This is an area of technological change and advancement.
As Euro 6 CO2 emissions take effect, common rail technology is advancing even faster. Control of emissions over time has become even more stringent, hence the requirement for improvement in technology in the fuel injection industry.
We are keeping pace with market place changes, and provide a service whereby we can supply, on an exchange basis, new or fully reconditioned common rail pumps.
Provided with these pumps is a twelve month guarantee protecting you against component failure.
Once the part is ordered, we can have it with you for next day delivery, as with all our products.
Common Rail has had such an impact on the diesel fuel injection trade, consequently demand for old type pumps and injectors has dramatically fallen but thanks to a number of enthusiasts restoring old vehicles and engines there has been a resurgence in popularity. In line with, we stock some old type pumps and injectors but we also have a wealth of experience in sourcing old style units.
Modern vehicles are well known for poor fault diagnosis. A vast amount of money and time can be used to try and diagnose errors. Test and reports help to eliminate any errors or faults with pumps and injectors as part of the diagnosis process.
We aim for a twenty four hour turnaround in fault diagnosis once we have received the unit for test. We can test 95 % of the current market of pumps and injectors and a swift diagnosis will help you pinpoint the fault quicker improving service to your customer.
Make and Models: Citroen Jumper, Fiat Ducato, Peugeot Boxer and Ford Transit Models
This engine was nicknamed the Puma and is part of the Ford Duratorq range of engines and it was introduced in 2004. The Puma engine range also includes 2.4 and 3.2 TDCI variants. These engines feature a Denso diesel fuel injector pump. Denso are a well-established, reliable supplier of automotive components which was founded in 1949, after becoming independent of Toyota car company. The 2.2 Duratorq is, ultimately, a development of the old Endura-D diesel engine that saw service in the Mark 2 Ford Mondeo in the 1980’s and 1990’s. The Endura – D engine has a trusted reputation for being reliable with a good build quality and this reputation has continued with the Duratorq range.
If you have a Denso diesel fuel injector pump that requires reconditioning, we would be happy to help. As with all reconditioning work we undertake, we will use brand new parts and provide a 12 month warranty. If you don’t have a pump to exchange, please call us on 01254 53545, because we may have the diesel fuel pump you need in stock.

This 1.7 litre diesel was originally designed by Isuzu and features a Denso fuel injection pump. Isuzu collaborated with General Motors in the design of the engine, with Isuzu having a reputation for the efficiency of the diesel engines it designed. The engine came into use in Opel and Vauxhall cars in Europe, and also by Honda. The engine was manufactured in Poland at the General Motors plant in the city of Tychy. This 1.7 litre engine was given the name Circle L.
This Circle L engine was developed over time, and had different variations. In 2010 the variant called the A17DTR was developed into the A17DTS. The engine power was 130 hp with torque increasing to 221 lb⋅ft between 2000 and 2500 rpm. The very first Circle L engine was called the Y17DT and was fitted to Vauxhall and Opel Astra, Combo, Corsa and Meriva 1.7 models from 1999 to 2003. All these models had Denso fuel injection pumps. If you have a Denso fuel injection pump that needs to be reconditioned, we would be very happy to help. Brand new parts are used in the reconditioning process and we provide a 12 month warranty. If you don’t have a unit to recondition, we may have a stock item on our shelves. Please call us on 01254 53545.
Makes and Models: 2010 Mitsubishi ASX (RVR), 2010 Mitsubishi Lancer, 2012 Peugeot 4008, and 2012 Citroën C4 Aircross.
This 1.8 litre diesel engine with Denso fuel management and injection pump is part of the Mitsubishi 4N1 range of engines that went from 1.8 litre to 2.4 litre capacities. The engines are developed and manufactured by Mitsubishi at its engine facility in Kyoto, Japan and are intended for its worldwide mid-sized passenger cars. The engine is a lightweight all alluminium unit, and development started originally in 2006, with full production commencing in 2010.
The engine is notable for being the world’s first passenger car diesel engine to feature a variable valve timing system (VVT). It also features a variable vane turbine in the turbo charger and a variable geometry turbocharger both of which provide ideal boost pressure for different driving conditions.
As well as being used in Mitsubishi passenger cars, this unit also found its way in to the Peugeot 4008 and Citroen C4 Aircross in 2012, and it has proven to be a highly reliable unit. The larger engines in this 4N1 range were only used in Mitsubishi vehicles.

Diesel Fuel Pumps
Prior to the advent of common rail, the diesel pump was one of the most important components in delivering diesel to the combustion chamber. The pump had to be timed within a degree to the engine, so to produce the fuel delivered into the compression ignition cycle. However, with common rail the fuel pump delivers fuel to the rail and the pressure and amount of fuel are controlled via the ECU using pressure sensor, volume sensor or pressure valve.
Our stock of common rail fuel pumps is wide and varied. The pumps will be either new or reconditioned in our workshops. With pre-common rail pumps, although our stocks are not what they were, we pride ourselves in sourcing exchange and/or outright pumps.
With over 48 years experience, our industry sourcing knowledge is second to none, so it is highly likely that we will be able to help out with your particular needs.
In the unusual circumstances that we are not able to supply your requested pump, we can collect your pump unit, recondition it in our workshops with a minimum of a three-day turnaround on the part. Please contact us for more details.
The function of a diesel injector is to convert diesel fuel from a liquid to a vapour that is sprayed into the combustion chamber of the diesel engine. It creates an explosion under compression.
On the old style of diesel, the timing of when the injector injects the fuel into the chamber was determined by the pump. With common rail and EUI engines the timing is now determined by the ECU or on board computer. The nozzle in the injector will spray the atomised fuel at a specific angle depending on the application.
On common rail systems, the injector can be triggered several times before the main injection and several times after the main injection, thus creating better fuel efficiency and noise reduction. These injectors are set up on equipment working to tolerances within 1 micron (0.001mm).
With almost 20 years experience in the test and repair of common rail and electronic unit injectors, Darwen Diesels can provide an experienced- backed quality service.
