Cummins Fuel Systems

Cummins is a well-established manufacturer of diesel engines and specialist parts, including fuel systems. Cummins fuel systems deliver the right amount of fuel to your diesel engine’s combustion chamber to drive optimal performance and fuel efficiency, as well as reduced emissions.

Cummins fuel systems offer a range of technologies, tailored to each engine model, encompassing traditional mechanical systems and more advanced electronic components.

Foxwood Diesel can supply Cummins fuel systems and pumps, which are readily available from stock.

Cummins mid-range fuel systems are also available from stock, including:

Cummins fuel systems offer an array of benefits, particularly for those with larger fleets, such as:

1. Improved fuel economy

2. Decreased fuel emissions

3. Precise fuel delivery

4. Durable and long-lasting designs

While a Cummins fuel system’s inner workings can vary depending on the specific model, the process generally goes as follows:

The fuel begins its journey in the fuel tank. It is then supplied to the fuel system by the fuel pump. The fuel pump draws fuel from the tank and sends it to the fuel filter.

The fuel passes through the primary and secondary filters, which remove any dirt and debris that could interfere with your diesel engine’s fuel system components. The fuel may also pass through a water separator, which removes water from the fuel. This helps prevent damage to the fuel system and avoids a decrease in combustion efficiency.

The fuel pump pressurises the fuel before sending it to the injectors. It generates the high pressure needed for fuel injection.

The fuel injectors have the role of delivering fuel to the combustion chamber. These injectors can be electronically controlled, delivering fuel at precise times, pressures, and quantities in order to optimise the combustion process. Once delivered, the fuel mixes with the compressed air and spontaneously combusts.

After combustion, the exhaust gases produced are transported out of the combustion chamber and through the exhaust system. Cummins fuel systems often employ various emissions control technologies to mitigate the environmental impact of diesel exhaust.
