Yeah diesel engines don't have a spark ignition system, the fuel essentially ignites by itself, so you can't just kill the sparks So the only way to shut it off is to either cut the fuel, cut the air, or release the compression entirely.

From study of these engines 200 cc is about 6 hp at full tilt , Fuel burn with diesel tends to be o.4 lbs per HP or 0.18 litres per HP . Life of good quality small types is about 2000 to 4000 hours about 170 days continuous . I would expect Chinese cheapo to be about 500 to 1000 hrs or 20 to 40 days continuous so on $200 dollors that is $0.50 cent to $25 cent per hour not counting consumables like fuel Lub oil and filters etc . These make good 12 volt or 24 volt generators from car alternators or dynamos to recharge battery banks . Best fuel effientcy tends to be top rated speeds but 60 % gas gives longer life of engines . Changing Lub oil frequently extends life so if oil change is every 50 hours do it every 25 hours as a example If engine is 6hp set alternator to be using max about 4 hp to not load engine too much and 4 hp is in 12 volt about 22 amps per HP or 88 amps . For go carts diesel is slow to change speeds so works best in steady speeds and direct drive no gears just clutch and reverse and forward . Boat engine works well also . Spare parts are often the same price as new engine so most peoples with cheapo gas and Diesel engine just buy another engine and cannibalise the engines as they buy them . Cold starts with di metal ether spray are hard on engine so de ice spray seems to work best from reports .Shaft outputs are better than side belts as the side force wears bearings out quicker . Used cooking oil cleaned and altered CETANE to run with 5% gasoline mix to thin out thick oil fuel will also probably work OK . Low temperature use often adding 30% Kero to fuel helps . If no Kero fuels available a 5% gasoline added helps or you make Kero with 7 parts paraffin and one part gasoline . It is common in many countries to sell diesel that is made mostly of Kero and that trick is common in many parts of the world to sell bad diesel oil mixed in with other junk fuels like methanol and used lubrication oils and water that can wreck these diesel engines and might explain the fuel instructions .Diesel pumps in diesel don't like pure Kero as they wear out from lack of lube oil but adding some Lub to Kero fuels can keep simplex pumps like these engines more happy . That trick won't often work with modern in line pump with its very high pressure solutions . Not good to breathe in these diesel fumes so best to make exhaust solutions to get rid of the micro particles that cause cancers . Keep up the good work

Clean fuel is critical with a diesel engine. The fuel shoud be run thru a fine filter before being put into the tank. The injector pump has minute clearances between parts, and anything that is even slightly abrasive in the fuel will kill the pump very quickly. Diesel will also develop interesting problems if used after standing for several years - apparently a bacteria or fungus will grow in the fuel, and clog the pump and injector! Also, air in the injector pipe will make the engine a reluctant starter, and may cause uneven running. Crack open the injector pipe coupling, release the compression, and pull the engine over until fuel leaks out of the loose fitting once the air has been expelled, then tighten the fitting again. And yes, there is an engine oil designed specifically for diesels. Normal petrol engine oil is not recommended for diesels.

[@snort455]

u can put a fungicide in the fuel to kill any fungus. Ive had fungus in bio fuel. Never in traditional diesel or heating oil.

[@Differentthings2006]

It sure is.

[@c.e.g7448]

The compression release is normally only for starting. It is best to turn the engine off with the throttle. That is why it does not keep running when you let the throttle handel go to minimum. This is the most simple diesel engine available. Everything is mechanically regulated. The amount of fuel injected is determined by the high pressure fuel pump. The injector does play an important role to. If the injector is not set up right it will open too soon and stay open to long. Or it will open to late and does not stay open long enough. In the first case the engine getst too much fuel and smokes a lot, it runs "to rich" as you call it. The power output will usually be ok. In the second case the power will be low and the engine will not start easily and does not run full out. These enginese are usually set up a little bit "to rich" as you call it. That way the engine starts easier and runs better. Fuel economy is less and the engine smokes more. Modern diesel engines have an electronic engine control unit (ECU) that controls the injectors and the high pressure fuel pump. This gives a much better fuel economy and less emissions.

[@Differentthings2006]

Interesting, I'm glad I'm able to learn about these things. It's cool that this engine runs fully mechanically. I am most familiar with small carbureted gasoline engines so a lot of the concepts carryover but it's interesting to learn the specific differences. Thanks for your comment.

If that crushed air filter tore the paper of the filter you'll dust your engine in short order. Look for a replacement as soon as possible and then fasten it down with a low plastic wing nut to help prevent futuristic over tightening,

[@ericdziadosz7145]

With diesel engines of any size, its not the speed that they are bought for, its the torque, and also why it has a larger flywheel. Double check your users manual for the correct weight of oil. Most gasoline small engines are in the SAE 30 oil viscosity range (how thick the oil is). Working on older diesels, I have seen as high as SAE 50 for summer time operation. Got called when a guy I know put 5w20 into a lawn mower engine that called for SAE 30, and wrecked the compression rings and started burning oil like crazy. Yeah, it rolls a lot of coal, but older EPA-exempt diesels will do that. Use the throttle to shut it down, the decompress is just holding a valve open, but it is still injecting fuel into the cylinder as it shuts down. Doesn't matter if its a single cylinder pull start 196cc or a 15,000cc 6 cylinder Cummins or a 32,000cc C32 Caterpillar 12 cylinder or any other sort of diesel. They all operate on a similar principle, just a heck of a size difference.

Yeah you're gonna want to use rotella or mobil1 or something for that. The sulfur and other crap just turns it black and conventional oil will degrade faster because of it.

Ether can cause a lot more detonation. Propane from a torch head is acceptable too in a pinch.

There are 3 grades of fuel for this type of engine it says to use Red fuel. You cant use the other 2 types. I didnt know this untill I saw a trucker talking about what type of fuel they have to use, they get tickets if they use the wrong kind.

[@marcmo7138]

Red fuel is off red fuel like farmers use. However back in the day you could buy Knox Super Red on road fuel but that was in the early 90's.

[@jcolbyt82]

The main difference between red diesel or #2 fuel oil versus non red diesel is where it’s legal to burn it. You can burn the non red diesel in any diesel engine that you want to. The red diesel has a red dye added to it to signify that it is not for on road use. Any diesel that goes in a vehicle meant for driving on the roads cannot have dyed diesel in it’s tank. Why? Because red dyed diesel does not have per gallon Federal or State road tax added. Roadway diesels have to burn clear diesel because when you buy clear diesel from a gas station, you are paying federal and state road taxes. That’s the biggest source of revenue for highway maintenance and construction. You can burn clear diesel in any diesel engine, even off-road or this diesel engine. It works the same, it just doesn’t have dye added. Plus you are paying highway tax for off-road use. No penalty from the govt for paying the tax when you don’t have to. If you drive a diesel vehicle on the road and they pull you over, stick a tester down in your tank and it comes out red, you are going to pay a fine. And not $100. In most states it is $10 per gallon or $1,000, whichever is greater. So for most it will be $1000. For large tractor trailers that hold several hundred gallon, the $10 per gallon rule kicks in and will go into the multiple thousand dollar range. So yeah, that’s the only difference between them. In the past the red diesel (fuel oil) would have higher sulfur levels but my understanding now is that it has the same low sulfur content of regular clear diesel. I have farm tractors and buy bulk red diesel. When I’m out sometimes I will buy road diesel and put in my tractor. It runs just the same. You can also burn kerosene in diesels. We used to put half kerosene and half diesel during really cold weather so that the diesel wouldn’t gel (freeze). But that was when kerosene was about the same price as diesel. Now you couldn’t afford to do that as high as kerosene is.

[@Differentthings2006]

@@jcolbyt82 wow, very in-depth comment. I did not know that, Good information.

[@brianbaird6528]

It's not smoking because it's running rich. Diesels don't have a rich or lean because they don't mix the air and fuel. They get full air intake all the time. How much power you get is determined by the amount of fuel injected. More fuel=more heat=more pressure in cylinder=more power. The governor adjusts this based on where you set the speed control (incorrectly called a throttle) and how fast the engine is running. If it's running much under the speed control setting, the governor's job is to get the rpms up to where the speed control lever is set as quickly as possible. This means it will inject maximum amount of fuel for a few firings until it gets the rpms up. In this case there is more fuel and it can't all burn. Petroleum based fuels like propane, gasoline, and diesel are made of hydrocarbons, chains of hydrogen and carbon atoms joined together. When there is not enough oxygen and too much fuel, the result is that the hydrogen all burns up and some of the carbon burns and then the oxygen is used up before all the carbon is burned up. That carbon is in very fine powder mixed with the carbon monoxide and carbon dioxide and water vapor that is blown out the exhaust. You call that black smoke. A black smoking diesel may be producing a lot of power, but it's wasting that carbon. It's the same as throwing out some of the charcoal out of the bag onto the ground before you fill up your charcoal BBQ grill. That's really kind of wasteful. If you need that much power on a regular basis, get a bigger engine so you don't waste fuel. A larger engine will also last longer because it's under less stress.

[@Differentthings2006]

Thank you for your comment. What you have said, is true. Although, I don't think it's incorrect to use the term throttle to describe the speed control lever. And as you described, having too much fuel for the oxygen to completely react with is the definition of a rich burn. Although in the case of the diesel does not negatively affect the horsepower. I have learned a lot about diesel engines since making this video, a lot of people have commented the same things that you said.

[@brianbaird6528]

@@Differentthings2006In the original usage of "throttle", at least in my understanding, meant to strangle an animal, cut off it's air. A diesel's speed control doesn't do that. A gas engine has a true throttle, because it blocks the air to the cylinder.

​@@brianbaird6528 Interesting, I have never heard that use. I think you're right, that technically a throttle requires some kind of valve, whether it be a flat slide or butterfly valve, etc. to block airflow. But I think of it as a synonymous term with speed control.

What's the advantage of diesel over gasoline when diesels twice as much do not use starting fluid on these little engines the engines are louder not really any more power several videos on KZbin about diesel engines today small engines everybody go out and buy them one do not use starting fluid on these little engines

[@Differentthings2006]

This engine has served me well for about a year and a half powering an air compressor. A gasoline engine probably would be better suited for the application but the diesel engine works just fine and the video performed far better than any other video I've ever posted, so people like diesel content, (hard cold facts). Diesel engines do have some benefits over their gas counterparts such as better fuel economy, and increased longevity. I bought it more for the cool novelty factor of having a single cylinder diesel engine, but it works great and I have no regrets.

[@Differentthings2006]

Another advantage of diesel engines over gas engines in the small engine world is you don't have to worry about cleaning carburetors I am draining gas before storage. Diesel fuel has a much much longer shelf life than gas and especially ethanol gas. So a diesel engine can sit with fuel in it for a long time and still be able to start up just fine.

[@twinklermystik7644]

Some of what I was going to say has already been covered in other comments, so I won't repeat them. The size of the flywheel is because of the compression ratio. It takes a lot of inertia to get it over top dead center. The higher the compression, the greater the rotating mass is required. And that extra rotating mass is the reason for the slower throttle response. And 19 to 1 compression is not unusual when you do not have glow plugs. Lower compression does not heat the air as hot and requires additional heat for initial combustion. But putting diesel fuel in a red can for gasoline is stupid. I've seen a guy destroy a $4000 motorcycle because he thought it was gasoline in a red can. Someone filled it with diesel. Get blue, yellow, or green. Anything but red.

[@Differentthings2006]

This is all good information that I've learned about the diesel engine engine except the compression ratio is 20 to 1 but of course the same principle applies. As for the red gas can I'm very familiar with what it contains, it's the only one we have that is that shape and size, so no one will be confusing at anytime soon. Although it would be smarter to get one that's a different color, we just didn't have one at the time of buying the diesel fuel.

[@antibrevity]

They're obviously trying to give this shipping protection, but it's still not quite good enough and they should probably attach the base plate to the bottom of the wooden box to completely keep it from moving and *then* add the styrofoam cap on top to prevent sway and protect the tank. If you're already paying for a wooden box, then you might as well use its rigidity to your advantage, much like wearing a selt belt in a car. As it is, there are too many sharp edges repeatedly cutting into the styrofoam as the engine flops around without restraint.

Procedendo alla cieca rischi pure di rompere qualcosa? Tu te ne intendi di pompe di iniezione per giudicare? Hai visto se c'e olio nella coppa dell'olio? del motore? Se l'olio nel motore probabilmente non c'è per questioni di trasporto, versare la quantità di olio motore prevista prevista; Per provare ad avviarlo, versare il gasolio nel serbatoio; poi facendo ruotare il motore, cominciare a spurgare di aria i tubi alta pressione dalla pompa di iniezione all'iniettore quando l'aria è completamente spurgata, il motore se non ha problemi si avvierebbe! un'atra cosa ; il motore che hai acquistato probabilmente lo devi montare su una macchina; la presa di forza( la puleggia) la hai già procurata? h visto che ala fine lo hai avviato l'olio nel motore c'è? Insomma video inutile! Traslate: Hello 1st mistake: Putting the manual aside: As a no less expert person, it is important to read the manual to acquire as much information as possible! Without going blind! (by trial and error) You dismantled everything from the valve cover which you should have dismantled just to check the valve yoke and instead you focused on the depressor lever! Why did you need to dismantle the injection pump? To see how it's made; If you had read the manual you would probably have been able to learn the preliminary operations necessary for starting! If afterwards the engine leaks a little oil from the tappet cover; At the base of the injection pump, No, you can complain: it's probably due to your tampering. Do you risk breaking something by proceeding blindly? Do you know anything about injection pumps to judge? Have you seen if there is oil in the oil pan? Of the engine? If there is probably no oil in the engine for transport safety reasons, you must pour in the required amount of engine oil; Before trying to start it, pour the diesel into the tank; Then by rotating the engine, begin to bleed the air from the high pressure pipes from the injection pump and the injector when the air is completely purged, the engine could start if it has no problems!

I saw that in the end you started the engine: there was oil in the engine ? In short, the video is incomplete and therefore useless!

Taking things apart, is how I learn, and I know enough about the engine to know that taking things apart and seeing how they work it's never a bad idea.
