Effects of engine parameters on performance can be investigated by using a mathematical model of the engine cycle, and the computed results may be used to optimize performance. The following design ...

Diesel is dead? Not quite yet. Achates announced Friday that it has produced a heavy-duty, two-stroke diesel engine with near-zero emissions that costs less than a conventional engine and is expected ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

SAN ANTONIO -- Nov. 12, 2019 -- Southwest Research Institute engineers developed a new certification cycle, the Low-Load Cycle (LLC), to gauge the performance of heavy-duty diesel engine ...

Manufacturers are leaving no stone unturned in the quest to improve the efficiency of their internal combustion engines. Just this week, we've seen a fastidiously engineered diesel engine from Ford ...

Internal combustion engine blowby, whether gasoline or diesel, occurs when part of the compressed mixture of air and fuel leaks past the piston rings during the compression or power strokes of a ...
