Diesel Fuel Injection

Common Rail Diesel

The times of smoke-blowing, slow and noisy, rattling diesel are truly over! Common Rail, modern high-pressure injection systems, the VP44 distributor-pump and Unit Injector and have certainly revolutionised the ever increasing diesel-powered vehicle market. The new Diesels are not only highly fuel-efficient, but also clean and powerful thanks to innovations in fuel delivery, turbo chargers and engine management systems. These systems let Diesel engines return torque, power, performance and emissions superior to other fossil fuelled engines and the same time produce better fuel economy.

Older conventional diesel engines have an engine driven injector pump and individual injectors on each cylinder. The pump sends a set amount of fuel to each injector via individual lines according to engine speed.

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, where the fuel pump output and pressure, and the injectors are controlled by an engine control unit that varies the timing and volume of injection to optimise performance. 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. The 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.

 

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. 

 

We hold dealerships with the main manufacturers of diesel fuel injection equipment like Bosch, Denso, Delphi and Siemens VDO Continental. We repair new, current and older technology fuel systems for a vast range of diesel applications and brands.

Is your vehicle lacking power, blowing smoke, using to much fuel? Contact our experienced Diesel Fuel Injection team on 1300 990 163 today for a quote or service.
