[3] In addition to cycling the fuel injector (pulse-width time, on–off), the engine control computer also determined the ignition timing, idle speed, exhaust ...

It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system (one primary filter for transmission sump, one for the fluid cooler return system).

Prior to 1940 the term "jeep" had been used as U.S. Army slang for new recruits or vehicles, [10] [11] but the World War II "jeep" that went into production in 1941 specifically tied the name to this light military 4×4, arguably making them the oldest four-wheel drive mass-production vehicles now known as SUVs.

A pump collects oil from the sump and directly circulates it back through the engine. In a dry-sump system, the oil still falls to the base of the engine, but into a much shallower sump, where one or more scavenge pumps draw it away and transfer it to a (usually external) reservoir, where it is both cooled and de-aerated before being ...
