Beautiful. I have no idea how you build something so small and so accurately and I'm sure I'm not the only person who thinks this. It would be wonderful if you could post videos during the build process of your next engine.

[@boksermotor]

Matthew F Holland Thanks for your kind Words. I have thought about making a video of an engine to be build, so perhaps I will.

loving the slow thumper thumper sound. reminds me of the bollinder my step grandad had in his canal boat. given these designs will burn almost anything in surprised they aren't more common. even the stratified combustion two stroke diesel is a variant of this. Brunel and his kin I'm sure are smiling upon you from the great bar in the skies.

[@adrienperie6119]

Find Hansen I have a question for you, why is this engine considered only semi-diesel ? Isn't the air fuel mixture ignited solely by compression ? Also, do you believe it would be possible to make an engine of similar size as this one but not diesel, with a spark plug ? And a third and final question, have you ever considered building a forced induction (like Americans say, "Supercharged") engine ? Also, since I am asking you a lot of questions, here is an engine you might not know about, which is amazing. It has powered boats and trains, it is called the napier deltic, and it is a British opposed-piston valveless, supercharged uniflow scavenged, two-stroke Diesel engine. A very interesting engine.

[@ruston48]

Hello Find Hansen, Superb! love it as it is. Your engines are some of You Tube's true Gems of all time! I bet you have tried already, will this engine run without blow lamp when running under some load ? Once a man with a Ruston hot-bulb engine told me his engine needed to be run under load to prevent it stopping, but I guess his are different circumstances. I'm imagining it running a fan or an old sewing machine :) Something without too much stress on it.

[@CHARLIE1955able]

[@DerpyRedneck]

Is it possible to build an engine like this one right here, but with an air compression of say.. 18:1 and only deliver the fuel to the cylinder only when the piston reached top dead centre like Akroyd Stuart himself did with his engines when he worked with engineers at Hornsby's?

[@gregorymalchuk272]

Derpy Redneck Yes. This guy has true diesel engines elsewhere on his channel.

[@hawks1ish]

So basically a hot bulb functions like a primitive glow plug? Or am I completely wrong and this also has glow plugs?

[@RJ1999x]

Joshua Lansell-Kenny I know nothing about hot bulb engines, but I build diesels and my guess to answer your questions is this. On a modern diesel the glow plug heats the intake to help start the cold engine, once started the compression creates the heat to keep it running. On this engine the flame acts like a glow plug by heating the incoming air and head, but because the compression is so low it needs the flame to keep creating the heat to combust the fuel

[@gregorymalchuk272]

Joshua Lansell-Kenny It works more like the glow plugs on nitro engines, where the heat of combustion keeps them glowing all the time.

[@cffellows]

Lovely engine, Find. I love how slow it runs. What is the compression ratio?

[@boksermotor]

Chuck Fellows Hello Chuck. Thanks for your kind Words. I think that the compression ratio is about 6-1. Regard Find

[@erniethecat5621]

Off by a decade. 1981.

[@jamest.5001]

I was thinking of buildings something similar, only larger and opposed piston twin cylinder, and nearly 200 cubic inch displacement, use a indirect injection, using a hydraulic pump to drive a piston / air compressor, at a small volume, high pressure, 50 bar +/-, and a second similar piston for the used oil fuel or diesel, the air gets forced into the injector each firing event the same, both into a 3mm orifice with a basically a small pipe protruding about 3mm, from a solid bar 30-40mm, with about 12mm of it, turned down to about 15mm, this screws into the head/ injection chamber, being about 25mm x 35mm that will also house a glow plug, the 3mm tube having a 1-1.5mm hole merging. With the 3mm at about 60° angle, the fuel connects there, then a 4mm ball with a 1.5-1.75mm rod coming off it, , the ball seating in the tube in the combustion chamber, the rod connects to a spring, keeping the ball seated, the spring has a cap threaded covering it, with a 6-8mm tubing connected to the cap, the fuel use about 4mm tubing, the injection pistons close by, with the check valves making it work, the air use a a 20 mm x 45mm bore and stroke , the fuel using a 8mm x by 20mm stroke, the hydraulic pump should make high pressure low volume, with enough volume to actuate the injector pistons with a fraction of a rotation of the crank, maybe use a spring loaded reservoir to store pressurized oil to actuate the injectors, when required, use a 50mm piston with 60 mm stroke, with about 500 psi springs keeping the piston/chamber closed, when filled it should have about 600-700psi using a safety relief valve to stop filling,. The ignition is controlled by a valve releasing the pressure to fire the injector pistons, the fuel injector piston is controlled by a bypass valve, throttling the engine, using a governor, the air blast should push the ball off the seat, ( it would probably be a good idea to use a guide on the ball shaft, ) but the fuel being injected into the air blast, should be vaporized when leaving the ball and seat, it also works as a check valve for the combustion, it's a Rube Goldberg injection system, go back to 1923 and it's probably about 3steps backwards for compression ignition engines, but I believe the extreme pressure air being injected through the fuel, into a high compression engine, (22:1 +) the injection air should be about 30-40:1 compression ratio, into the combustion chamber, it will probably run at a peak of 400-600 rpm, using heavy flywheels, probably 4, weighing 50lbs each, with a crank made from two similar flywheels, with about 200mm stroke, and a 4" bore, the injector should reduce the amount of fuel required, and burn extremely clean, it should be as clean as gasoline, if not cleaner,, I'm sure there is better ways to achieve the injection method that is mich simpler, this is the only way. I can think to build it at home, with machined components, it should make lots of TQ, I would like to build a 2stroke version also, similar to the Detroit 2stroke diesels, except use a secondary large bore piston, with a shorter stroke, to scavenge the cylinder, possibly enough displacement to slightly supercharge the intake stroke, or maybe incorporate a turbo, to allow the scavenger pistons to only be used on start up, I want it for a stationary engine, for power generation, a 10 HP gas engine running gets old fast! A low rpm engine with extremely long stroke, with a bit of sound management, can be basically silent, being opposed twin, it should be well balanced, so not shaking the house from 300meters away , Sorry to ramble, I would like your opinion if you can follow my rambling! Thanks, and good day! ✌️

[@thisoldchevy2371]

how does a hot-bulb engine work? does the hot bulb cause combustion?

[@twistedyogert]

Yes, the hot bulb is heated by a blow lamp before starting. Before the power-stroke when the piston is at bottom-dead-center i.e.: at the end of it's stroke length before it starts rising, an injector squirts some fuel into the hot bulb. The heat of the bulb causes the fuel to evaporate and while some of the fuel does burn, there isn't enough air for a big fire, when the piston begins rising, air is forced into the bulb, causing even more fuel to burn, forcing the piston down to begin the exhaust stroke.

[@robot797]

who does it stop when there is no heat to the glow lamp normal engines wont stop running after the heat is removed

[@mattgrooms3298]

This engine uses heat for ignition. A gas engine uses a spark plug for ignition and a Diesel engine uses compression to ignite fuel. This engine has no spark plug and low compression so it can't run by itself.

[@deserteagle190x8]

Johndeere 100 hot bulb engine can normally run with out the heat (heat is normally any to get it started) about this one can not sustain it own heat there for it need it all of the time.

[@boksermotor]

Johndeere 100 Thanks for your comments. There are two reasons why the blow-lamp must be burning all the time. 1. much heat is conductedto the cylinder-head and the water-cooled injector because of the short distance, 2. low compression heat because of the short 20 mm stroke.

[@sc0tte1-416]

+Find Hansen Thank you for the explanation, I'm not an expert on diesel engines but I was wondering why the compression alone wouldn't cause combustion to occur. I was not aware that this type of engine had a lower compression. This engine is an amazing piece of work, hopefully it will be taken care of and passed on for generations to come and be enjoyed!
