Basics of diesel intake, compression, power and exhaust

Some 2.0 HDi vehicles may develop hard or non-start problems which can be attributed to the fuel injection system. This may be due to failures in either the low pressure feed to the high pressure pump, or the high pressure pump itself.

Despite making its debut in the mid 1950’s, Gasoline Direction Injection (GDi) has only recently come into its own, as vehicle manufacturers look for more meaningful ways to meet increasingly stringent emissions standards.

Here we take a look at the common causes of injector failure, what the symptoms are and how to diagnose them for a best practice injector service.

For smaller shops, it’s not always feasible to buy large testing equipment to check the flow rate of diesel injectors. In those cases, you can use the high voltage lead test...

It’s important to avoid contamination of injectors during a repair. Contamination during repairs can come from dirt around the fittings, your wrenches, your hands and many...

Non common rail technology can be broken out into three types: in line, which is sometimes called a rotary pump; an individual control pump and a unitized injection pump.

PIDs – or Parameter IDs – are important to understand when making diesel repairs. They are part of the heart of the diesel common rail and system.

Understanding how diesel injectors spray can help you understand injector diagnosis better.

Insufficient pressure and flow are an indication that a fuel pump is under-performing, but do not necessarily mean that it is failing.

Ten years ago, diesel got a bad rap. But today, the Delphi common rail is earning diesel a reputation for efficiency and power. Common Rail is the fuel injection system that meets strict emission regulations. It includes a high pressure pump, injector, rail, filter and ECU. Proof that engineering a fine fuel mist, like a fine wine, gets better with time. Please visit our DNA application to check your Common Rail Injector has been repaired by a Delphi Approved Workshop using Genuine OE Delphi parts.
