I am trying to get a reasonably sound and fact-based estimate of oil consumption for a six liter six cylinder two stroke uniflow scavenged and turbocharged diesel engine. So my question is: Can you provide an estimate of the expected oil consumption of a newly rebuilt (to original standards) DDC...
Assume that mean piston velocity, displacement, and brake mean effective pressure are constant. Also assume (for the purposes of this discussion) that the crankshaft is infinitely long.
Regarding torsional excitation to the crankshaft, we know that the torque dynamic signature is much greater...
I have been trying to confirm the definition of effectiveness for an air-to-air intercooler installed between a turbocharger compressor discharge and an engine intake manifold. I looked around the internet and found a number of answers (some contradictory - no surprise), and I finally went to a...
We are making plans to set up an air cooled opposed 6 cylinder engine with digital electronic fuel control. As the target bmep is about 25 bar, the heat load on the engine exceeds the typical air cooling function, and we plan to use water injection to help cool the cylinder head and prevent...
More than a year ago (12 Feb 09), Painterman(Mechanical) started a thread 71-237389 to address the question of opposed piston engines. The thread was popular, and some of the discussion diverged to the subject of Prof. Ingr. Dr. Peter Hofbauer's OPOC engine. (Hofbauer is the ex VW Powertrain...
I am interested in bsfc and bsac data for the 3 cylinder 799 cc diesel engine that Mercedes employs in the Smart Car. I think the engine is a 65.5 bore x 79 stroke 3 cylinder, but I don't know the Daimler Benz engine code (which I also would like to know if anyone knows it).
I think the...
I've done a bit of web searching for wear data for hydrogen fueled ICE poppet valve and valve seat inserts. I am primarily interested in various material combinations. Most of what I have found has been anecdotal. I suspect that quantified wear data is closely guarded, but I'd like to ask the...
