Common Rail 101: Injector leak test

Drivers demand more from their vehicles, expecting them to run as reliably in year 10 as they did in year one. Delphi is ideally positioned to meet such high expectations...

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

Replacing a fuel pump can become a costly mistake if it is not the true cause of a fuel related problem.

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.

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 other places....

Here’s a safe, fast and easy way to check the alcohol content of gasoline using a graduated cylinder.

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

Tested to OE standards to be fast, accurate and efficient. Proven to significantly reduce emissions.

Achieving future emissions targets will require even more meaningful innovation as vehicle manufacturers look to improve engine management, electrical power consumption, vehicle weight and integration of alternative powertrains, without compromising on vehicle performance. The good news - as a leading OE manufacturer, we already offer a range of proven, green technologies that deliver significant improvements in fuel economy, emissions and engine performance. 

Delphi electronic unit injectors feature OE engineering and advanced technology to offer significantly enhanced fuel economy and performance. 

Precision is key for the fuel pressure regulator on any vehicle. So when you need to pick a replacement part, choose Delphi — the brand that’s been OE engineered to perform consistently. We test our fuel pumps for performance and durability, and we use our results to make better parts. That’s why Delphi holds more than 30 OE-proprietary innovations and 150 patents in fuel module and pump design.

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.

When it comes to building fuel modules, Delphi applies its OE expertise and technological leadership to deliver the highest level of performance and customer satisfaction. Delphi engineers each fuel module with the same stringent standards we apply to the parts we make for top vehicle manufacturers like Volkswagen and PSA.

Achieving future emissions targets will require even more meaningful innovation as vehicle manufacturers look to improve engine management, electrical power consumption, vehicle weight and integration of alternative powertrains, without compromising on vehicle performance. The good news - as a leading OE manufacturer, we already offer a range of proven, green technologies that deliver significant improvements in fuel economy, emissions and engine performance. Whether it’s a diesel, gasoline or electrified vehicle. Or a car, light commercial, heavy duty or off highway application. Better still, we keep these vehicles running the same way throughout their lifetime with a comprehensive range of aftermarket solutions including OE parts, tools and know-how.

Delphi fuel parts aren’t just high quality, they’re Delphi quality. We put over 100 years of under-the-hood experience into every part we make, so they deliver 100% satisfaction for you and your customers.
