Heavy duty & off-highway Diesel Fuel Injection

Since the introduction of legislation in the early 1990s, the industry has seen a significant reduction in emissions levels. In fact, it would take 15 heavy duty vehicles today to produce the same level of particulate emissions as just one vehicle did 20 years ago. At Delphi, we’ve been at the forefront of these improvements, delivering cleaner, greener and more fuel efficient commercial vehicles. We also provide the parts, tools and know-how to service these vehicles, right the first time, every time. Keeping them driving as good as new for life.

Rich OE legacy

Our heritage dates back to the legendary CAV brand, and the introduction of in-line and the iconic DPA pump – the best-selling rotary pump worldwide. Both were revolutionary for their time, setting new standards for reliability and power, and we’ve continued to push the boundaries ever since.

Three choices for fleets

By providing three choices – new, reman and repair – we can provide fleet managers with convenient service and maintenance at a very competitive cost.

Latest generation OE technology

Our latest generation F3 system takes engines beyond the 2021 global emissions and fuel economy regulations and through the next decade. Based on our proven Euro VI Common Rail technology and capable of 3,000 bar injection pressure, it delivers a substantial improvement in emissions, fuel economy and refinement for the lifetime of the engine.

OE-approved repair

In addition to new and remanufactured units, we also offer authorised repair through our global network of Delphi Diesel Centres. Replacing all wearable and performance critical parts, with like-for-like OE, and using OE-approved test plans and equipment, it offers a quality but economical solution.

Reman

For an equally fast, yet more cost-effective turnaround we offer a range of remanufactured parts. Available off-the-shelf, typically within one to two years of vehicle launch, they are built using OE parts, equipment and processes, and are calibrated to exacting OE specifications.

OE expertise in the aftermarket

Of course, we’re committed to supporting these technologies in the aftermarket. We offer a range of new OE components, identical to those originally fitted, including our pioneering Electronic Unit Injector, Electronic Unit Pump, Smart injector and Multec® Common Rail.

Commercial vehicle diagnostics and test

Our dedicated diagnostic solution for trucks, buses and trailers, supports the key commercial vehicle manufacturers and systems, including the ability to carry out dosing tests, Adblue freeze monitoring calibration, system drain down and regeneration of the SCR system. We also offer a range of OE-approved test equipment for quick and accurate test and repair of the latest heavy duty applications.

Training from the OE experts

Designed to help you prepare for the very latest heavy duty diesel fuel injection technologies, our extensive training programme covers the repair of key systems, including Electronic Unit Injector and Pump and Smart injectors. Learn more about our training.

Resource Highlights

A diesel injector performs a simple, yet very important job – it delivers fuel as a fine mist into cylinders, where it then combines with air.

In this Masters of Motion video, our Delphi Expert looks at a common diesel injector fault found in transit vans. Discover all this:

• Spot the symptoms of a failing diesel injector

• The fault code to look out for

• How to replace the faulty part

What equipment do I need to pinpoint a fault?

Once you’ve narrowed down the fault to a failing diesel injector by knowing the symptoms, you will need a Delphi BlueTech DS480 to run the necessary checks.

Why do I need to know the symptoms of the fault?

By knowing what to look after you can save time tracing the problem and fixing it. Symptoms can include failure to start the vehicle or taking a long time to turn over.

What can happen if the fault isn’t fixed?

Failure to fix a faulty diesel injector can lead to other parts failing as a result and even a breakdown.

What is ‘limp home’ mode?

This is an early sign of a failing injector, and is a security feature which kicks in when the engine or transmission control unit picks up a fault. In this mode, the vehicle switches off less important functions, like the air conditioning, and reduces the speed of the car.
