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 glass jar.
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)

How a 2 stroke detroit diesel engine runs
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

PAUT MOTOR-REVOLUTIONARY ENGINE.wmv
PAUT ENGINE -
Prototype 2 is performed as an engine with two-sided pistons, positioned
at 90° to each other, in combination with PAUT two-stroke cycles (fig 1).
Such construction provides an engine containing less assembling parts,
having smaller mass to power and overall-dimensions to power ratios, which
are the presumptions for a successful product to be accomplished and for
low cost production/exploitation to be expected. Smaller mass, compared to
the prior art engines, derives from the fact that PAUT engine contains
considerably less assembling parts lacking elements such as: rods,
camshafts, camshaft's driving parts, some valves, large heads.
The very construction of the two-sided piston (fig 3) has more
advantages. Contact area between two-sided piston and cylinder is
considerably larger compared to prior art pistons. Hence, specific
pressures are lower and since the two-sided piston is lubricated under the
pressure, the friction is considerably smaller, the more so as we know that
normal force Fn in the engine center equals zero (fig 2a).
All these results with less wear of the piston and the cylinder. Such a
two-sided piston has considerably smaller mass compared to the prior art
assembly it replaces, consisting of two pistons with their prison-shafts
and two belonging rods, resulting in lessening of linear motion inertial
This construction has still more advantages as compared
to prior art engines such as:
- better controlled cooling of cylinders not being adjoined to each other
- smaller friction inside the engine due to less moving parts
- increasing the capacity of this engine, though considerably, results in
overall dimensions to increase only slightly
- gravity center is posted lower (it is in the engine center)
- better forces configuration in the very engine, while negative forces and
torques nullify each other completely (fig 2b)
- it is possible to dismount pistons and cylinders without entire
dismounting of the engine
- no special tools nor machines were used to produce this engine
- there is less noise due to the design of the two-sided piston
- though the cycle is of two-strokes, the lubrication is performed as if it
The objections on this construction should be as follows:
- due to the compressed construction , the starter should be mounted on the
gear box, but with some endeavour it is possible to mount it on the very
- the force on the output journal of the crankshaft (fig 2a) is twice
compared to the one at prior art engines, but this problem becomes
negligible with a proper design of the journal and of the operating shaft
- there is no oil sump at this engine, hence an additional oil-pump is
- since it is a two-stroke cycle engine, the engine cylinders are submited
to higher mechanical and thermical load comparing to four-strike cycle

Banks Top Diesel Dragster: NHRDA Nationals
On March 6th, 2010 the Banks crew tested out the rail's new "Stroker" 427
cu. in., twin-turbo 7.0L Duramax engine
at the NHRDA Nationals in Wittmann, Arizona. The numbers for this trip out
were 7.670 @173.54. We were a little faster back in April 2009 when we ran 7.17 @
181.08. We've also run a best trap speed of 190MPH with the car on a
separate test session. All those runs were with our twin-turbo'd Duramax, and now we're getting set to hit
the track with a supercharged configuration. Stay tuned for that! More info
