Diesel Engines
Diesel engines do not have preignition problems because fuel is injected at the end of the compression stroke, therefore higher compression is used. Most modern diesel engines use a turbocharger. This is because the exhaust from a diesel is exceptionally strong making it excellent for powering a turbo. The range of engine speed is narrower, allowing for a single turbo to fully power the entire engine range. Turbochargers can also achieve higher boost pressure than superchargers, which is necessary for most diesels.

Famous quotes containing the word engines:
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
