how does a diesel engine work vs gas
How Direct Injection Works. Direct injection engines use two fuel pumps, a low-pressure pump and a high-pressure pump. The low-pressure pump sends fuel from the tank, through the fuel filter and into the high-pressure pump. The engine’s camshaft drives the high-pressure pump, allowing fuel pressure as high as 2,500 pounds of force per square
But, there’s more. Diesel engine compression is 20:1, while that of gas engines is 10:1. This implies that the compression of air is almost double in diesel engines which is why parts therein such as block and cylinder heads, crankshafts, pistons, and valves are designed to be more resilient. Moreover, the higher compression ensures complete Chevrolet offers owners of Silverado 3500HD and 2500HD a choice between the Vortec TM 6.0L V8 gas engine and Duramax® 6.6L V8 turbo diesel engine. The Ram 3500 trucks come with the 5.7-Liter V8 HEMI® gas engine. Finally, the GMC Sierra 3500 has the Vortec ® 6.0L Variable Valve Timing V8 SFI gas engine. Figure 1. 1:fuel injection, 2:ignition, 3:expansion ( work is done), 4:exhaust [1] A heat engine is a type of engine, (like the motor in a car) that produces macroscopic motion from heat. When people rub their hands together friction turns mechanical energy (the motion of our hands) into thermal energy (the hands get warmer).We’ve previously discussed this in our overview of what a glow plug is, as well as how many spark plugs does a diesel engine have. A diesel engine compresses at a ratio of between 14:1 and 25:1, whereas a gasoline engine compresses at a ratio between 8:1 and 12:1. This higher compression ratio of the diesel engine results in better efficiency.
