Viking Aircraft Engines - Engine Week 2020

[@TheArchitectJC]

Always loved Viking. more HP, range, fuel economy, and power than a Rotax 912, at quite literally half the price. I cant do it yet, but they are at the top of my list for when I finally build my long range bush plane. I just love that these are so affordable for the performance they offer. Other manufacturers have strengths and I still shop around just for fun and try to learn about others, but its hard for me to ever say "yes, this is worth double the price of a Viking". They dont push boundaries that much, but they do push the boundary of accessibility, and that is far more important to the world of aviation to me.

[@ExperimentalAircraftChannel]

Well I hope this glimpse into their shop and what they do there helps you with making a decision one day. Thanks for taking the time to join in on the conversation here! I appreciate your support!

[@desertfox3860]

Engine technology has certainly come a long way since I learned to work on them back in the mid 1950's. Thanks for the video.

[@henryware9440]

I have to salute this man for his incredible efforts and expertise making the Honda engines viable for aircraft use.

[@theflynlion]

Excellent video! The A to Z of how Viking acquires their engines and gets them ready for the customer. I was on the fence with regards to getting another Rotax versus an auto conversion engine. After visiting the shop myself and getting a personal tour from Jan and Alissa, I was very impressed with their facility and what they’re doing with these engines. Jan fired up a V90 for me...instantaneous start and it purred like a kitten. I was sold! Just purchased the V90 a couple of weeks ago for a CGS Hawk II that’s being built now.

[@ExperimentalAircraftChannel]

Very cool! Hope you get to fly your CGS Hawk early in 2021. Thanks for stopping by to say hello today!

[@theflynlion]

I was planning to have it on display at the already postponed DeLand Showcase in January, but now that’s been cancelled. All dressed up and nowhere to go, lol.

[@kencohagen4967]

I really like your videos. Keep them coming! When I took Auto Shop in high school we were given a Ford truck chassis, everything from the body down, to learn on. It had fallen off the truck when it was being delivered to a local Ford Dealer. That’s a great way to get an engine, if you can get a hold of one. When the EPA mandated their emission standards one of the areas that was needed improvement was an ignition system. The old points style ignition because when the points wore down the dwell of the ignition coil changes over time along with the ignition timing. Dwell is how long the coil is charged by the battery. The longer the better. In the old days dual point distributors had two sets of points the increase dwell, and that created a hitter spark. But dual ignition gave the engine two paces to wear. When they changed to electronic ignition, that was no longer a problem, and the engine won’t need constant tune ups to keep running clean. That also helps the engine run better longer, and in an aircraft that mean the horsepower rating remained constant, not high one day and after a few hundred hours of use would have to be serviced to bring everything back to spec.

[@ExperimentalAircraftChannel]

Will do! Thank You! All good points on the tech talk their. Thanks for sharing. Good story and great experiences!

I am putting one in my Zenith 750 STOL, once I stop dumping money in my Cessna 210. Different mission, goal is to leap off my own property and fly low and slow. The Viking will no doubt do the leap off the ground fast. I might have to build me a set of Cruzer wings and tail so I can move a little too.😄 I own a 1966 Corsair Corsa, I was looking hard at going that route, since I have already built 3 - 164 140HP engines., but the modern technology in the Viking and true 130HP performance won for me. Plus I can get a low mileage Honda, similar VIN replacement motor, if I ever need it, for less than $2000.

This is the most accessible manufacturer on the market. you get a lot from these guys! They are like having a Rotax 912, a very sought after engine, but with more horsepower, more reliability, a little less expandability, and literally half the cost.

[@MrWATCHthisWAY]

This is a subject I am extremely familiar with. I have been a Honda buff for years and know the quality control that goes into each build. Tolerances of .0001” essentially a blueprint build on each engine. I overhauled about 35 engines and tried to keep those tolerances on each build. I have ran the different engines at 7-8000 rpm continues and have never blown an engine while racing them. Crashed a few! The only issue I’ve seen with Mr. Wades system is the rubber torque bushing mount flange. I can see they have made a BIG improvement on the flange itself. I believe this WAS their only major issue and I’m glad they redesigned & manufactured new flanges. This is engine is on my short, short list. The only thing I will be changing is the radiator. I would prefer one that’s completely welded and not with plastic caps. Not that I have ever experienced a failure that wasn’t caused from a competitor throwing debris into my radiator it’s just a piece of mind. The only thing a pilot needs to worry about is enough fuel. Another good one Bryan.

[@HobbitHomes263]

I sure would like a Honda engine. I have a 1990 Honda CBR 1000F motorcycle. It has 87,000 miles of very high RPM operation. It has never leaked coolant or oil. It doesn't burn oil. compressions are all factory fresh. The vavle buckets don't even need shims. I am totally impressed with their metallurgy.

[@johnpumphrey7655]

I really appreciated the detail in the video. Thank you. Unless I missed it, all discussion was on the Honda engines and didn’t notice the Viking 90 / Mitsubishi engine mentioned. Would it be fair to say that many of the modifications and testing processes are similar?

[@ExperimentalAircraftChannel]

YES. All very similar. Sorry... at the time of me popping in (and our schedules aligning) they had as you can see nearly a dozen of the 130hp models ready to go but none of the others at the time. I did "pan around" the installation on the aircraft in their hangar to showcase. Sorry I didn't go into detail on that one. Also didn't want to create a 30min episode... because then no one would watch! :-) We all have such short attention spans these days!

[@dirtcop11]

A Honda engine becomes a Viking. So if you modify a Saab engine does it become a Samurai? Loved the video. There are a lot of reliable engine adaptations for kit planes and scratch built planes. I am old enough to remember a Model A Ford engine in an airplane.

what sensor does the engine come with? coolant, oil levels and temps, pressures etc? EGT or O2? Being a crusty old fart, I just like Steam gauges. I suspect the 750 panel has plenty of room for my needs

[@gocanada9749]

I am curious, did these Honda engines come that that capsized car carrier in Charleston SC ? Sounds about right because it might take 8 miles from the port to the car carrier that picked up the Hondas, I know because I used to work on one of those ships !

[@quidestnunc9238]

Did I miss the Aeromomentum visit or the conversation with the Canadian who reps for Edge here in North America?

[@raydreamer7566]

To understand dual spark plugs in an older aircraft motor is to understand the failure rate of a magneto and that those motors could not produce full power without dual spark plugs because of a weak and low voltage spark. This is not the case in a newer modern gasoline motor.

[@allankrosner679]

The main reason for two spark plugs in classic aircraft engine is that their pistons are over five inches in diameter. The flame front moves too slow to span that distance with one spark plug.

[@JimBronson]

Was somewhat puzzled by the included equipment. Evans coolant? K&N air filters? Honda has an excellent OEM coolant that is very long lasting and IMO that's what should be used. Evans is for drag racing applications where you cannot use glycol based coolant due to the fact it fouls the track if it leaks coolant. Evans also does not cool as well as a water/glycol mix. Granted, the boiling point of Evans is 375F, but your engine will run hotter for a given load than it will with the OEM coolant. And K&N filters let more dirt through, period, proven many times by oil analysis. Use a traditional paper filter.

[@donjayamaha6174]

Do you use the Honda Original ECU for the conversion

[@Blackcloud_Garage]

Can it run on Low Lead AV gas found at airports or do have to plan on finding MOGAS at the destination?

[@alissaeggenfellner4613]

You can use either, when using 100 LL an additive should be used, this is similar to many engines using 100 LL

The Eggenfellner Back Story (and, as a long ago Reporter then Bureau News Editor for Dow-Jones Newspapers, I assure you that there is always a Background Story): probably before you, Bryan, were interested in Aviation, Jan E. was attempting to convert and sell Subaru auto engines for use in Experimental planes. Long story short, he had more than one hundred cash deposits (only he, his lawyer and bookkeeper know the exact number) and, after years of putzing with engineering problems, took that company into Bankruptcy with no refunds of deposits.

[@Talasas]

They don't use it because of sheer cost. It's used extensively in race cars where it can be re-used on frequent tear downs and car collections where the cars sit. I would have no issue running it, it's far less corrosive than glycol.

[@alissaeggenfellner4613]

We use it with a slight pressure (5 lbs) cars are much higher as you know. The reason being if there were ever to be a leak you wouldn’t lose as much fluid, it’s lifetime and doesn’t cause corrosion in the engine or radiator (water can), some places in the engine are hotter than other like around the exhaust manifold - which is built into the cylinder head, water could turn into steam pockets in those areas and not cool like Evans (which has a much higher boiling point) even without pressure.

Anyone have a 195hp on a murphy rebel? or any of the murphy aircraft?

[@MrBtdobie]

Auto manufacturers beat the crap out of these engines in testing. Thermal shock test, hundreds of hours at WOT, contaminated fuel, ect. Auto engines are very reliable, but they have an achilles. The whole operation of the engine is dependent upon a working electrical system unlike a traditional aircraft engine. Many also have the added complication of a gear box. So as with everything there are pluses and minuses.

[@knottymatt]

Massive Honda fan and also a fan of offering affordable engine options for aircraft, I have a Honda car, bike, lawnmower myself, but isn't that 1.5L turbo 'earth dreams' the engine that has reliability issues and has been banned in China? Dilution of oil and carbon build up issues (Scotty Kilmer). Keen to understand what work Viking to prep it for aircraft installs.

[@alissaeggenfellner4613]

Dilution of oil and carbon build up are avoided by running it overboard just like a typical aircraft engines. I think this was mostly an issue in the early years (not now) We have some videos called “Viking Talks” that go through a bit of the process more and are always sharing more

[@knottymatt]

@@alissaeggenfellner4613 Thanks! I'll have a watch.

[@ExperimentalAircraftChannel]

I hope your question(s) were answered below...if not ASK AWAY. I want you to be able to get an education from this ENGINE WEEK series and be able to make a decision if this is an option for you... or not. Thanks for taking the time to watch today!

[@JimBronson]

The issues you mention are endemic to turbo direct injection engines of any make. Doing a lot of short tripping on them with 87 octane fuel leads to oil dilution because they run a rich air-fuel ratio (AFR) to avoid knocking and detonation on the lower octane fuel. In a grocery-getter or soccer-mom application the oil never gets to a high enough temperature to burn off the extra fuel that ends up in the oil. This issue is mitigated by running these engines on higher octane fuel that doesn't require as rich of an AFR to avoid knocking/detonation and/or running the engines harder and longer, which results in appropriately higher oil temperatures that will burn off any fuel that does end up in the crankcase. An alternate way to mitigate the dilution/loss of oil viscosity is to just run thicker oil. Honda recommends 0w20 oils even in their turbo engines but I personally would move that up to somethingW-30 synthetic at least. And do oil analysis to set your change regimen, don't rely on the oil life monitor in the car. Once the oil falls out of viscosity range - 9.3 to 12.4 centistrokes viscosity for Xw30 at 100C/212F, change it. As Mrs. Eggenfellner notes this would be less of an issue in an aircraft application because it will be running at relatively high power settings even in cruise.

[@nishanttomar7826]

Viking aircraft,why can't you buy new parts from oem,s

[@John-nc4bl]

This Honda / Viking engine has too many parts to go wrong and is too heavy when compared to Lycoming and Continental aircraft engines.

[@deeremeyer1749]

Those engines are basically "scrap metal" going to the "vendor" and they come out of "JDM" (Japanese Domestic Market) vehicles that no longer "meet specs" per the "supplier" Honda and the "Japanese government" and must be replaced instead of "serviced" because they CANNOT be "serviced" sufficiently to "meet specs". The "markup" on those BOAT ANCHORS. is at least 10,000% if you consider their "value" on arrival from the "vendor" to be "scrap price". And this assclown refers to "robotically put together" specifically to suggest "human error" had nothing to do with their "scrap" status. That is complete bullshit. There is some "automation" involved in "mass production" of "car engines". But there is no "autonomy" whatsoever where "robots" have "replaced human workers" and are "building engines" actually assembling ANY precision "internal" OR "external" engine parts.

[@YooperScott]

Those that are new to the game make whatever decision you’d like, but do your due diligence and research Mr Eggenfellner’s past with Subaru engines on airplanes before you purchase. Same guy and basically same marketing story now as then just a different engine manufacturer. It did not end well. Again make whatever decision you’d like, but buyer beware.

[@oktavius8292]

Just got our Eggenfellner Subaru back together with its third short block. Really getting old fixing stuff. Really ruins the idea of alternative engines as there are a lot of engine specific choices to wiring and fuel system. Lot of work and money to swap to a traditional engine. Not saying all alternative engines are a bad choice but we definitely believe the Eggenfellner Subaru was the wrong choice. But at least I get a laugh every time I remove the Eggenfellner intake manifold and looking at the frying pan emblem on the bottom (yes, intake is two pans welded together). "Farberware - Quality Cookware" I'm sure the non-stick coating was an eggeneering decision.

[@PARTner91]

There’s no doubt that automotive engine technology is fantastic and reliable. However, since any particular engine model offered here has a low (maybe zero) number of installs in a given aircraft model, it’s like you’re being a long term test pilot for that engine install. I’m more comfortable going with an engine such as a Rotax which has thousands of installs in a given aircraft model.

[@alissaeggenfellner4613]

I’m confused at your response, we have over 600 Zenith installs and many in Kitfox, RANS, Searey, PPC. Over many years we have over 1000 engines sold. The engines are very well tested before they ever hit the market. Even a tested Rotax can fail, but it’s about picking what’s best for you.

Go with what you know... or take the time to learn about something new. That is the point of this ENGINE WEEK Series. I hope to reveal most of the details that were or are in question to have you better informed so you can more easily make a choice. And I only wanted to cover engines that are actually "In Production" and the most popular of those. These are quite popular and being installed in aircraft at a pretty aggressive rate these last few years. But of course.... you can decide which platform you feel most comfortable with for your application. Thanks for taking the time to comment here today and for watching!

Some technical points to consider: - GDI as implemented on an auto engine provides negligible improvements in efficiency at aero application (high) loads, as explained in detail in the EPA Technical report: www.epa.gov/sites/production/files/2018-10/documents/sae-paper-2018-01-0319.pdf - GDI has a single high pressure mechanical fuel pump, with no redundancy - Auto ECUs have not been optimized for the aviation use case, and must be hacked to reduce the potential of switching into limp mode due to non redundant sensor failures. - the Gearbox damping is still being tested in the field , by customer installations. 4cyl gearboxes are very difficult due to large reverse torque pulses, and resonance issues with unloaded props. For reference: www.epi-eng.com/propeller_reduction_technology/torsional_vibration_issues.htm and more specifically for 4cyls www.epi-eng.com/piston_engine_technology/torsional_excitation_from_piston_engines.htm - present day high compression auto engines with this much complexity added to meet auto industry mileage goals (see point 1), are very heavy in comparison with simpler, lower parts count, aviation purpose designed engines (example rotax, ULPower etc), even those with injection.

The gearbox dampening system has been tested for almost a decade with over 600 flying, in fact it offers dampening to prop strikes, which allows protection to the engine. There is no limp mode in our ECU is in fact optimized specifically for use. Please understand the entirety of the system before writing false ideas. There has NEVER been a high pressure fuel pump problem. If someone wants accurate information I suggest talking with us directly or customers There is reasons for everything that is done and has been tested through and by us before ever hitting the market. The comments in fact show you don’t understand the system and/or conversion or what is done.

@Pete Zut I had a few similar concerns to he honest. I am not an "owner" but I also have been following this platform for some time. And I would say that the "proof-is-in-the-pudding." I respect that JAN flies behind every one of his engines (butt-in-the-seat) and has made improvements over the years. And it seems that there are now many flying with no issues. I am NOT defending anyone here...simply stating the facts that have presented themselves over the last several years. You are very welcome to come to you own conclusions of course, and you should, but so far so good on these Honda's. Thanks for watching today and engaging in conversation! I welcome you back anytime. Are you currently building something and if so... what? :-)

@@ExperimentalAircraftChannel thx for your channel! Its a great asset to the eaa homebuilding community (speaking as a 25yr member - also following viking and Jan over the years). I commented only to provide the community with something to complement cute puppies and couples ;) i am building a europa (with both short and long wings), fly a europa (rotax uls) as well as a hoot’n’a’half Hummelbird (1/2vw). kzbin.info/www/bejne/rZ2cgmyKd5WCrM0 Cheers and blue skies!

Thank you for the input Pete. We love port injection and direct injection. It is true that we were somewhat amazed at the difference the GDI proved to provide, once testing started 5 years ago. I think the gain for an aircraft is 2 fold: First, the knock threshold is much greater, allowing high compression AND advanced ignition timing, all on mid grade fuel. Another 4-5 percent is gained by allowing full open throttle and flying the engine on the propeller. Eliminating pumping losses over the throttle plate.

[@PeteZoot]

@@eggenfellner to your last point, Hondas throttle by wire system, as well as their ecu programming on their earthdreams engines utilizes stratified charge (leaner than stoic and your wide open throttle scenario) only at low/mid power and warm up with regular injection patterns at stoic at high power settings. Are you changing the honda ecu gdi programmingand using their throttle by wire? If not, your last point is confusing, as it isn't a diesel.

Why would you insist on 4130 chromoly tubing to be TIG welded when it was specifically designed with Metallurgy requiring it to be oxy-acetylene welding. When 4130 and I believe 4140, chromoly tubing is TIG welded it must be stress relieved at all the weld with an oxy acetylene torch. Otherwise you have an Austin medicazone which is subject to failure. Even NASCAR was making this mistake requiring roll cages to be TIG welded instead of oxy-acetylene welding. That metal was specifically designed for oxy-acetylene welding???

Fantastic video !
