Diesel Fuel Injection Systems

POZA 14At Express Diesel we provide the know-how on the latest diesel injection systems. We service and repair injection pumps and injectors produced by Bosch .

We have permanently aimed to be contemporary with the latest technologies, in order to offer quality services to a very large range of diesel system users. Following this idea, Express Diesel was the first service in San Diego area to use, for diagnosing the fuel injection aggregates, the Bosch EPS 815 test bench with electronic KMA. This test bench offers the possibility of diagnosing and fixing of both mechanical and electronic aggregates.

The Common Rail injection system is the latest system released on the automotive market. The system is named after the shared high-pressure reservoir (common rail) that supplies all the cylinders with fuel. With conventional diesel injection systems, the fuel pressure has to be generated individually for each injection. With the common rail system, however, pressure generation and injection are separate, meaning that the fuel is constantly available at the required pressure for injection. Common rail systems have a modular design. Each system consists of a high-pressure pump, injectors, a rail, and an electronic control unit.

With conventional diesel injection systems, the fuel pressure has to be generated individually for each injection. With the common rail system, however, pressure generation and injection are separate, meaning that the fuel is constantly available at the required pressure for injection. Pressure generation takes place in the high-pressure pump. The pump compresses the fuel and feeds it via a high-pressure pipe to the inlet of the rail, which acts as a shared high-pressure reservoir for all injectors – hence the name “common rail”. From there, the fuel is distributed to the individual injectors, which inject it into the cylinder’s combustion chamber.

This new system has a lot of advantages :

  • Clean and highly efficient fuel injection due to extremely short spraying distances and multiple injection
  • High engine power and smooth running with low consumption and emissions
  • Can be used with all vehicle models due to modular design, from micro cars to heavy luxury limousines, from cars to heavy-trucks, from engines to boats, from construction to agricultural machinery.

This new technology has become very popular on the diesel market in the last years, but requires very high quality test equipment, very well trained technicians, specialized tools and cleanliness in the workshop.

Diagnosing and repairing are complex methods which require professional touch, thus, it is the job of a diesel center to do the repairs of these modern diesel systems.

We, at Express Diesel, as San Diego’s diesel center, have this latest technology that can diagnose, adjust and repair Bosch Common Rail System. We are part of an international network of diesel specialists and we are the first in San Diego that can offer a repair with genuine parts, genuine software, genuine test-benches and genuine knowledge
