EXPERIMENTAL Deposit analysis

Several OEMs and FIE suppliers provided field injectors or sticking injector components for evaluation. Some of these came from engines running development tests and others came from vehicle field failures. Some were from LDD engines and some from HDD engines. In addition, one failed high pressure fuel pump was also received. In each case, the

Background on diesel injector internal deposits

Regulations mandating a reduction in emissions from diesel engines have resulted in changes to both engine fuel system design and diesel fuel composition. The use of High Pressure Common Rail (HPCR) fuel injection systems has become more common place as engine and vehicle manufacturers strive to reduce emissions. Diesel fuel and diesel fuel additives are

Background on diesel fuel additives

A variety of additives are added to diesel fuel for many different purposes. Many additives are added at very low dosages, typically from 10 to 200 ppm by weight, except for cold flow and cetane improvers, which can exceed 1000 ppm. In this publication, deposit control additives (DCA) and corrosion inhibitors are specifically mentioned. DCAs

Diesel injector internal deposits in High Pressure Common Rail diesel engines

J Galante-Fox, J Bennett Afton Chemical Corporation, USA ABSTRACT The phenomenon of diesel injector internal deposits is a growing issue in several key fuel markets, with an increasing range of automotive vehicle manufacturers reporting problems in the field. This paper will describe Afton Chemical Corporation’s in-depth investigations into the sources of these deposits. Afton was

KEY CONTROL STRATEGIES

The system and its control strategies make a huge contribution to the performance of the engine. The Delphi control strategies integrate injection system strategies and overall engine strategies [3]. The torque and power strategies, figure 9, are mainly driven by the system control (Delphi EMS calibration). FUEL INJECTION L3C B ■ APC / SPC Individual

DCM3.7 ELECTRONIC CONTROL UNIT

The DCM3 ECU family is largely used on Euro 4 and Euro 5 applications. Depending on the type of application, such as small MD engine or large MD engine, two fixing options exist: engine mounted or chassis mounted ECU. The key advantage of the DCM family of ECU is its high degree of integration, including

DFI 2.5 INJECTOR

Delphi’s DFI2.5 Diesel fuel injector, figure 8, is the latest generation of solenoid actuated injector that is used on MD applications. Due to the larger capacity engine application range in comparison to the LD one, some elements of the design were taken to strengthen the current injector technology to cope with higher flow requirements and

Drivetrain components

The drivetrain is a key element to improve in this Medium Duty application high pressure pump. The DFP3.2 pump is used on Tier 3 Medium Duty application [1]. For the DFP4.2 Medium Duty application, the specific load on the bearing induced by the pumping event at equivalent pressure will remain the same as the Light

High pressure components

As previously presented and taking into account that the work done for the Medium Duty application is significantly higher than that of the passenger car applications, the inlet and outlet valve design were judged marginal on the hardest passenger car & light commercial vehicle application, requiring to be reinforced. Since the performance of the valve

DFP4.2 DEVELOPMENT

The key areas to focus the development of the DFP3 based Medium Duty Common Rail pumps on, are the outlet valve, inlet valve, bearings, and seals.
