   facet fuel injection pump

The fuel injection system comprises a Fuel Injection Pump, Injection Nozzles, a Fuel Filter, and a Fuel Tank. The fuel that is drawn from the fuel tanks by the Feed Pump is filtered through the Fuel Filter, and is delivered to the injection Pump.The fuel that is delivered to the Injection Pump is pressurized into a highly compressed state, and is delivered via the Injection Steel Pipe to the Nozzle. The fuel is then injected in an atomized state into the Combustion Chamber, where combustion takes place.

A portion of the fuel that is delivered to the Nozzle lubricates the sliding portion of the Nozzle and returns to the Fuel Tank via the Overflow Pipe. To prevent the fuel delivered to the injection pump from becoming excessively presurrized, an Overflow Valve is provided in the Fuel Filter or in the Injection Pump itself. If the feed pressure from the Feed Pump exceeds a prescribed value, the Overflow Valve opens to allow excess fuel to return to the Fuel Tank via the Overflow Pipe.
