I have a couple videos of my 2 stroke detroit diesel powered pickup here on youtube, and I have gotten hundreds and hundreds of questions about how in the world it runs, and lots of people who do not believe that it really is a 2 stroke. So, I'm sorry, I don't have the best voice in the world, and I'm not the best at explaining things or getting the right words to come out, but I did my best in this video to try to give you an idea of how it runs.
Working view of 2 Stroke Opposed piston Engine
Saw this at the Mount Gambier show and had to share.
Really appreciate the interest shown so far.
Some good views of rockers and scavenge blower and a look in the inlet
showing the piston working as the valve plus the injector shooting into a
As a kid I remember the sharp bark these engines made at full noise.
Apologies to anoraks who want to know all the details but it was hard to
hear the chap at the engine because of surrounding noise.
The chugging noise you can hear is the vintage Ronaldson Tippett engine
which is turning this engine over slowly so you can see how it works.
Further notes: It is a 2 stroke cycle which fires every revolution and uses
the piston on the inlet side to open and close the port and the piston on
the Exhaust side to uncover the Exhaust at the appropriate time while the
blower is not to supercharge but to "scavenge" the spent gases ( basically
the air blows in the inlet and out the Exhaust at a slight pressure)

Cummins Diesel Engine First Start
STARTS AT 3:10 ---
This engine and its twin were built by my father. He installed them in his
33' Bertram. Sorry about all the cranking. I meant to cut out a large
section of that, but somehow I forgot about it.
FAQ: Why is it white? It is common for boats to have white engines.
Why is water coming out of the Exhaust? The engine is cooled by a continuous
flow of seawater, or in this case water from a hose. It comes out of the
Why is it cranking for so long? Is the starter fried now? The starter is
fine. Everything was completely dry at the beginning of the video. It
just took some time for the fuel to be delivered.
Both engines are running (and starting) great over 5 years later. Thanks
