Diesel Injection Pump Housing
Pump Housing Product Overview
The pump housing component pumps diesel into the cylinders of a diesel engine. Developed more than 200 years ago for the rail industry, it’s a part that remains every bit as important today.
A typical diesel engine relies on compressed air to ignite fuel. It’s the job of the diesel pump to supply that air and the extreme heat to go alongside it.
This component is tasked with controlling the volume, pressure and timing of fuel sent to injectors. For this reason, it’s a part that needs to withstand heavy loads. Performance hinges not just on the delivery of the compressed air but the pumps ability to prevent leakage at the same time.
Diesel injection pump housings tend to operate thousands of times a minute, powered indirectly from the crankshaft via one of gears, chains or a toothed belt. Fuel is only ever provided to the fuel injector at the optimum point – delivering power only when it’s required.
Pump housings are calibrated in such a way as to deliver just the right amount of fuel into the combustion chamber.
The MAT Foundry Group offer a wide range of Pump Housing Applications for Common Rail Technologies. MAT has been a market leader for more than a decade in the design and production of pump housings made of ductile iron.
We ensure the highest level of quality at the best possible costs and the optimal weight.
How Do Pump Housings Work?
Unliked a Distributor Injection Pump - which uses a single injection pump that rotates to meet the combustion chamber individually - the Injection equivalent sees each cylinder in the engine encompass a pump and connected plunger.
When diesel fuel is added to the pump, one end allows it to move into the chamber ahead of combustion. The other is the plunger.
As the latter moves back and forth, it creates the all-important opening for the fuel to enter the combustion chamber.
This motion creates the necessary force to compress the air in the chamber, which in turn creates the heat needed to ignite the fuel.
Diesel Injection Pump Housing Facts
It takes 250 millionths of a second to inject fuel into an engine’s combustion chamber.
The first pump housings were developed 200 years ago
Diesel injection pumps are believed to last between 100,000 and 150,000 miles
