    Why not a 4 Cyl diesel in a light truck

    I am developing a 3 cylinder diesel that I believe will light up a F150 or Siverado truck. 240 CI common rail injection that is light weight. I have been working on the project for over two years and I hope to have running prototypes on the dyno in a few months. Thanks, Mike

    Torque vs RPM carachteristic in diesel engines

    Torque is relative to cylinder pressure. If you move the torque closer to operating Rpm you will inevitably increase the engine operating temperature. Most marine diesels can only survive if they free up at operating rpm. Most marine failures are because of improper gearing or proping placing to...

    Harmonic Dampeners

    These engines are all four cylcle. We will be using pilot injection and that helps with the detonation issue. The bearings are 4" od full compliment needle bearings. We are not completely sure that this will work but the force is being spread accross two of these bearings with each combustion...

    Harmonic Dampeners

    I understand the dampener, but we also intend to internally balance the engine and I feel that this cnc part aproach will hopefully eleminate the need to balance the crankshaft. Other parts will need to be balanced as well. I appreciate the recomendation. I'll contact them and see what they have...

    Harmonic Dampeners

    This crank will be used on a three, four and six cylinder in-line engine application. The crank is sectional. The wings are billet machined so that all are the exact same. The main journals as well as rod journals are also billet machined. The parts are put together by the use of induction...

    Harmonic Dampeners

    This dampener will be used on a new diesel engine design. It will have a new sectional crankshaft with HD needle bearings on the mains and rod journals.

    Calculating exhaust gas CFM.............

    I am developing a new diesel engine design and we are begining to machine and assemble the prototypes. During our dyno test research we found that we could make 340hp with 575cfm of ambient air. This was accomplished in a 305ci four cylinder at 2800rpm running 37psi boost. The new designs should...

    Harmonic Dampeners

    Is tuning of a dampener necessary on diesel engines that have a max rpm of 3500? Is any good rubber dampener okay?
