Runaway Mini Model True Diesel Engine-Safety Valve ?

A runaway situation even for a small model diesel engine, is not for fun.

I had my runaway situations, when the engine failed to start after several start attempts caused by missing compression, it could be a sticking exhaust valve. Then after full compression again, the engine started with very heavy pre-ignitions because of the unburned fuel in the combustion chamber that ignited far to earley, and ran on that fuel for a few seconds with very high speed. That is why I made a safety valve, mostly to prevent the heavy pre-ignitions. I would like to thank you all very much, for your kind and warm comments. Best regards. Find.

[@raygale4198]

Your projects are always immaculate, when do you have the time? :-) The safety valve you have fitted was often fitted to old diesel engines in the early 20th century, it was not intended for over speed protection but for cylinder overpressure limiting to prevent blowing of head gaskets or in extreme situations cylinder liners splitting in high load conditions. Early gaskets and metallurgy had their weaknesses. A positive way to stop an overspeeding engine that was used by General Motors on their 2 stroke diesels was to have a spring loaded flap in the air inlet duct, the flap was held open by a cam and pawl, in an overspeed the pawl was lifted allowing the cam and flap to rotate and close the air inlet, it was a last resort stop as the high negative pressures developed in the inlet duct could draw the oil seals out of the Rootes blowers. Love your projects.

[@magnificentmuttley154]

Thank you for posting! Seems like ancient history now, but in the 70's & 80's small kit engines were still made in the USA. Gasoline & steam powered were most common. Diesels weren't easy to find, but still available. This was to teach school children the basics of internal combustion engines, & inspire a new generation of future engineers... My personal experience as a child was with gas powered model airplane engines, & the Capsela modular toy set, from which a variety of cars, bulldozers, & boats could be built. Also water pump, air pump, for model aquaduct & water reservoirs to be built in a sandbox or terrarium

[@chrisegan7537]

You can still find steam models, and glow and gas engine powered models are still around but certainly sold as "big boys toys". While IC power will always have a place in certain models it has largely been replaced by electric, brushless when you need all out power and brushed for when you need fine control of speed. Also small scale aeronautics has gone full high tech with FPV UAV's both winged and multirotor. Engine models like the one in this video are finely crafted pieces by a small handful of people, mostly retired machinists and mechanics that have dedicated themselves to making running art!

What a beautiful piece of engineering that is. All engineered to work well and look good - I agree that flywheel is particularly nice. And very interesting to hear the rough calculations of the forces involved - much bigger than I would have guessed.

Another way could be adapt the adjustment handle for the compression, so if a runway occurs, you can stop the compression and so it stops the engine? I noticed that even with the safety valve opening, the engine still gains speed.

I had and old automatic diesel L300 1 ton van. I was always worried about a runaway engine. I'm aware that even putting a manual into a high gear @ a standstill & letting the clutch out will not nessirarily stall a runaway engine. Nice, smooth driving (& slow) van, but engine under the front seats gave me no confidence of stopping a runaway.

[@dustinandtarynwolfe5540]

Yea it's cool but I think the valve is getting too much play here. Maybe it's just me but I'd prefer to have the engine be able to rev at least a bit without dumping all the compression out. Of course it's just a model engine but I think I'd probably want to power something with it. Otherwise it's just a paperweight. But to each their own, it's a cool thing anyway.

[@pirminkogleck4056]

you can adjust this valve ! if he built stronger spring , the valve pressure can be higher, also it depends on the lengh of the spring and the diameter of the spring wire! this engine is able to rev a lot higher but its usefull torque is in the lower rpm as you can see as he puts a good ammount of load on the flywheel ! i am sure you can power a small watchmakers lathe or a small drillpress with that engine ! or a water pump would be powered with ease! Finds engines are a work of art. i am curently building a injector and want to build a replic of those engines, and i can tell you the injector needle alone is a pretty crazy part to machine ( 0.8mm thick ) i spend days only for this needle ....Find is realy telented , or is it godgivenb, i cant tewll..but those engines are a art !

[@andrewbaillie6291]

Beautiful work you do.

[@kaithomsen9726]

I cant see how the valve would stop a runaway situation. It´s function looks to be the same as the pressure relieve valves on the old B&W diesels. The valve opens from ignition pressure at startup so the engine doesn´t blow the cylinderheads or headgaskets from excessive pressure. As soon as the engine is up to normal speed the valve stays closed, even under full load.

Beautiful. I still don’t understand the safety valve, what makes it “safe”? Is it to bleed off excess compression?

[@Texassince1836]

If the engine were to run away (stick at full throttle) the valve will open, preventing it from reaching an unsafe speed

[@joeblough2485]

@@Texassince1836 Some engines can run away even if you close the throttle. They can start to run on their own engine oil. Detroit 671/6V53 comes to mind. It has to have a blower to run and some have turbo's also, They can begin to run backwards if you stall them. Fun.

[@Texassince1836]

@@joeblough2485 close the throttle on a detroit and itll stop. The only throttle on a detroit is only there to stop the motor if it runs away. And if you were to bleed off cylinder compression (what this video is showing) a Detroit wouldn't be able to burn its own engine oil.

[@joeblough2485]

@@Texassince1836 I see what you are saying. having been around many Detroit runnaways myself, i can honestly say that is not always true. If the fuel injector shaft sticks open or if the governor is stuck or inverted, then the engine can still breath through the crankcase...etc ..you know how it goes.

[@jenseirikskogstad5901]

I had the Sabb semidiesel engine who run away so insanelly, it was danger then I cut the fuel due motor oil came from crankcase since the engine was a two stroke engine. The motor oil was ignited by hot bulb and ran fast before the oil was empty in the crankcase before I opened the fuel to run normal (Sabb semidiesel is lubricated by force feed box lubricator who has motor oil who are not reused again after the oil has been into the bearings, cylinder etc). In the large diesel engine has safety valve such as in ship engine to prevent damage the engine in case the propeller came out of sea and in the sea again in the sea who affected the engine due load of propeller in this high wave in bad weather.

Could you not cut off the fuel in a runaway situation? Lovely engine.

[@mybuickskill6979]

Alot of times runaway is from fuel being dumped in unchecked from another source. Like the seals on a turbo being too worn and dumping oil(which burns like fuel) into the intake... The best method is cutting air to the intake, or compression(spark source) which the valve here does.

[@darioinfini]

@@mybuickskill6979 Kinda makes you wonder why they don't incorporate a safety valve into diesel engines. You can just search right here for diesel runaways, scary and destructive. Some kind of emergency pull valve would save a lot of hassle.

[@mybuickskill6979]

I was curious same just a big valve like an exhaust cut out post turbo in the intake stream could do a pretty solid service in the event of a runaway. I think the biggest issue. Is the rarity of it happening today, makes the "it'll never happen to me!" Excuse pretty close to useful @@darioinfini
