Toyota is adding 1.2 million vehicles to a major recall in the U.S. to fix possible fuel pump failures that can cause engines to stall.
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
In 1981, a Delco Electronics ECU was used by several Chevrolet and Buick engines to control their fuel system (a closed-loop carburetor) and ignition system. [10] By 1988, Delco Electronics was the leading producer of engine management systems, producing over 28,000 ECUs per day.
The L is the first L engine produced. Toyota solely refers to it as the L engine, not the 1L engine. 2.2 L (2,188 cc), four-cylinder diesel engine. [7] Bore and stroke are 90 mm × 86 mm (3.54 in × 3.39 in), with compression ratios of around 21.5:1 [8]
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
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 reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
