Starting with the 1986 model year, the AMC straight-4 engines used a throttle body injection (TBI) or single-point, fuel injection system with a new fully computerized engine control. [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 ...
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).
The Willys L134 (nicknamed Go Devil) is a straight-4 flathead automobile engine that was made famous in the Willys MB and Ford GPW Jeep produced during World War II. It powered nearly all the Jeep vehicles built for the U.S. and Allies. [1] It was later used in a variety of civilian Jeep vehicles.
When emissions and fuel economy are a priority, the final MPFI versions of AMC's 2.5 L engine are considered superior. [10] Tests of the newly downsized 1984 Jeep XJ with the initial carbureted version and five-speed manual transmission returned 15.3 mpg ‑US (15.4 L/100 km; 18.4 mpg ‑imp) on the first tankful. [12]
While for direct-injection systems, the in-tank fuel pump transports the fuel to the engine, where a separate fuel pump pressurises the fuel (to a much higher pressure). Since the electric pump does not require mechanical power from the engine, it is feasible to locate the pump anywhere between the engine and the fuel tank.
The Willys MB and the Ford GPW, both formally called the U.S. Army truck, 1 ⁄ 4 ‑ton, 4×4, command reconnaissance, [9] [10] commonly known as the Willys Jeep, [nb 5] Jeep, or jeep, [12] and sometimes referred to by its Standard Army vehicle supply nr. G-503, [nb 6] were highly successful American off-road capable, light military utility ...
For the 1999-2004 Jeep Grand Cherokees using the NV247 transfer case, in "4-All Time" mode torque is applied to only the rear wheels under normal driving conditions. A gerotor pump is connected between the front and rear output shafts and senses any speed difference between them. When the shafts are turning at different speeds (wheel slippage ...
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
