Bosch Inline Fuel Injection Pump, Feature : Durable, Heavy Power

Anand Automotive Traders is the best supplier and exporter of Bosch inline fuel injection pumps in Bhutan.

The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smoothly. Simultaneously, the pump also controls the amount of fuel needed to gain the desired power.

The injection pump does the job of both the throttle and the ignition system needed in gasoline engines. When troubleshooting a gasoline engine, you check compression, fuel, and spark.

A diesel doesn't have an ignition system, so there is one less thing to go wrong with it. Major advances in the development of the diesel engine are a direct result of better fuel injection. Here is how the injection pump works.

Working of Bosch Inline Fuel Injection

The first pumps to use plungers to force metered fuel to the combustion chamber were developed back in the 1890s. It took almost forty years, but in 1927 Bosch introduced the mass-produced helix-controlled inline pump. These first pumps look a lot like the Bosch P7100 (P-pump) on the '94 to '98 Dodge Ram 5.9L Cummins engines.

Sometimes called jerk pumps, they are constructed from separate pump and plunger units connected inline, one per cylinder. They are activated by a cam, which is mechanically connected to the engine. Still, the pump can vary timing, although not to the sophistication of an electronically controlled system.

Inline injection pumps look like mini-inline engines. The earliest inline injection pumps delivered 3,000-5,000 psi of injection pressure, while the newer Bosch P7100, found on '94 to '981/2 Cummins engines, delivers 18,000 psi of pressure.
