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)

:::: INFO ADDED ::::
Many do NOT understand the meaning "2-stroke", which 98.5% of the world
population do. The definition of "two\2-stroke" do NOT (I REPEAT; "DO
NOT"!!) say wether the engine has valves, carburettor, injection or not,
but rather how many strokes the piston has to take before new air\fuel
enters the cylinder. The modern type two stroke diesel engine have valves,
are direct injected, are supercharged\blowed and have full pressure oil
HOW A TWO STROKE DIESEL ENGINE WORK:
1. When the piston is at the top of its travel, the cylinder contains a
charge of highly compressed air. Diesel fuel is sprayed into the cylinder
by the injector and immediately ignites because of the heat and pressure
inside the cylinder. This is the same process as 4-stroke diesels.
2. The pressure created by the combustion of the fuel drives the piston
downward. This is the POWER STROKE.
3. As the piston nears the bottom of its stroke, all of the Exhaust valves open. Exhaust gases rush out of the cylinder,
relieving the pressure.
4. As the piston bottoms out, it uncovers the air intake ports. Pressurized
air fills the cylinder, forcing out the remainder of the Exhaust gases.
5. The Exhaust valves close and the
piston starts traveling back upward, re-covering the intake ports and
compressing the fresh charge of air. This is the COMPRESSION STROKE.
6. As the piston nears the top of the cylinder, the cycle repeats with step

This is just some video of me messing around in my driveway so all you
detroit diesel fans can hear the engine more. The last video I put up of
this truck became so popular I figured I'd put another one on here. I did
not put the engine in myself. It was like that before I obtained the
truck. It used to have a 350 gas motor in it.
This is our 24 cylinder Detroit that we are putting in a custom 359
Peterbilt. It will use an Allison Transmission, and the engine will be in
the front of the truck. We are starting off with 40 foot 4" X 14" rectangle
rails, not sure how long it will end up being.
