High-pressure common-rail injection technology has revolutionized the diesel industry. Over the last decade, it has allowed engine builders to run higher injection pressures (as much as 29,000 psi in ...

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 ...

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 ...

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 ...

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 ...

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 ...
