Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...

It’s been more than a decade since high-pressure common-rail technology revolutionized the diesel industry. With its first application appearing on the ’01 LB7 Duramax engine, it should come as no ...

Picture an old windup desk clock. Now cross it with a gasoline engine, adding a tiny crankshaft and pistons. Tack on a few Buck Rogers bits, so it looks like Rube Goldberg's toaster. Flow gasoline ...

Vapor injection heat pump systems represent a significant advancement in heating technology by integrating a secondary injection of refrigerant vapor into the compressor. This process enhances the ...

The key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

Gregg Petersen's Hilborn-injected Chevette. The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor ...
