Pioneer Engine

This engine, with slight variations, is a model of RudyKouhoupt's "PIONEER".
It is a non-compression engine. When the crank has the piston at 6 degrees ATDC, the intake valve is opening and fuel enters the cylinder as the piston moves. When the crank is at 78 degs, or the piston is halfway down the cylinder, the intake valve closes.
At 79 degs the breaker points open firing the spark plug. At 180 degs the exhaust valve opens and stays open until 360 degs when it closes and the cycle repeats.

will you sell that?! lol i want on of those

Unless I build duplicates in the future none of my steam or gas engines are for sale, but thanks for asking.

Interesting! Two questions, though: What do you mean by "Non-Compression?" How does that work? Fuel won't combust effectivley unless it's pressurised. Also, how powerful is it?

[robertfilipiak]

The engine fires midway through it's intake stroke or 90 degrees from top dead center. It's entire power stroke is only the next 90 degrees making it a rather inefficient engine, but a real curiousity. Gasoline does not have to be pressurized to combust. An open container of gas will ignite if a flame is placed near it.

What`s the point of noncompression engine?

[robertfilipiak]

Just the fact that it was non-compression was reason enough for me to build one. It really wouldn't be practical as a working engine because it dosen't develop as much HP as a conventional one.

The real pioneer was a Belgian. By 1859, Etienne Lenoir's experimentation without electricity led him to develop the first single-cylinder two-stroke engine which burnt a mixture of coal gas and air ignited by a "jumping spark" ignition system by Ruhmkorff coil, and which he patented in 1860. The engine differed from more modern two-stroke engines in that the charge was not compressed before ignition. This one is a copy.

it could power a pencil sharpener

I have been drawling plans to build an engine i am almost finished will proly start the build this comming summer, and i kinda thought that u might just be able to run this on compressed air and or steam since there is no compression stroke? i guess u could call it a doulble slide valve single acting steam engine?

[mechfeist15]

that is awesome! any chance you could go it to more detail on how it works? if i could work out what was going on i'd have a go at making one.

Good for you ... and remember ..... some of the best inventions come from engineers as we are much more open minded to try new things than scientists.

Look up the 'Eric Laithwaite Lectures' ... he was a great engineer.
