Diesel Fuel Injector Pump

The automotive Diesel Fuel Injector Pump is the device that pumps fuel into the cylinders of a diesel engine. Traditionally, the pump is driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft. It rotates at half crankshaft speed in a conventional four-stroke engine. Its timing is such that the fuel is injected only very slightly before top dead centre of that cylinder's compression stroke. It is also common for the pump belt on gasoline engines to be driven directly from the camshaft.

When an automotive fuel injector goes bad, automotive engine performance is negatively affected. The purpose of a fuel injector is to inject a predetermined amount of fuel into an engine cylinder to facilitate engine combustion. A bad or faulty fuel injector disrupts normal engine combustion by altering the amount of fuel that is injected into an engine cylinder. A faulty fuel injector may cause a rough engine idle if it fails to deliver a steady, constant stream of flow to a vehicle's engine. A dysfunctional fuel injector may inject too much or too little fuel into an engine's cylinders. Both scenarios can cause a rough engine idle. A faulty fuel injector (or injectors) will prevent a car's engine from starting. If no fuel reaches a car's engine, engine combustion (starting) cannot occur. If a fuel injector cracks or develops a split fuel-injector line, fuel can leak out onto the engine manifold of a car's engine. offers a wide selection of top brand name aftermarket parts shipped same day from local warehouses around the country.
