Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
Kugelfischer injection (also called System Kugelfischer) is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH [1] Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles.
Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber. Direct injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or a sophisticated common-rail injection system. The last is the most common system in modern automotive engines.
Before electronic fuel injection showed the way forward, European engineers created radically and wonderfully complicated mechanical fuel-injection systems.
The Ramjet is a continuous-flow port-injection system. Unlike later fuel injection systems that used electronics, this one is based on purely mechanical principles. The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel ...
The 4JB1 is a 4-cylinder naturally aspirated watercooled in-line direct injection and also a high revving high output diesel engine with its VE rotary injection pump. Horse power is 90ps industrial version. torque is 135 lb.-ft. at 2000 rpm . while the light version 4JB1 uses gear type oil pump and Bosch "A" Type mechanical injection.
