Fuel Injection

Diesel Fuel Injection


The Common Rail system takes its name from the shared pressure accumulator (Common Rail), which supplies all cylinders with fuel. Common Rail diesel injectors share a single fuel rail that is driven by a high-pressure mechanical pump. The fuel pump output and pressure along with the injectors are controlled by an engine control unit that varies the timing and volume of injection to optimise performance.


Forget having a smoke-blowing, slow and noisy and rattling diesel engine. Advances in Common Rail, modern high-pressure injection systems, the VP44 distributor-pump and unit injectors have certainly revolutionised the diesel-powered vehicle market.


New diesel engines are not only highly fuel-efficient but also powerful thanks to innovations in fuel delivery, turbochargers and engine management systems. These systems let diesel engines return torque, power, performance and emissions superior to other fossil-fuelled engines while producing better fuel economy.

Do you need genuine new or exchange injectors at great prices and fast delivery? Want to chat with an expert for technical advice? Call us on (02) 96817700 or email

Sophisticated Diesel technology requires sophisticated testing, calibration, repair and service equipment. Sydney Diesel Centre has highly-trained and experienced technicians to test, calibrate and repair pumps and injectors to manufacturers specifications.

The Electronic Diesel Control (EDC) controls all the injection parameters with extreme precision – such as the pressure in the rail and the timing and duration of injection – as well as performing other engine functions. A more precise fuel mix delivers better efficiency, which usually means more power and lower fuel consumption. Common Rail engines are usually quieter and more refined as well.
