Development of Diesel Engine using New Fuel Injection System - Direct Monitoring of Fuel Injection Pressure using Injector with Built-in Sensor, and its Applications

1. Overview Recently, diesel engine has been improving its environmental performance. However, it is still difficult for the diesel engine to adopt the strengthening of emission regulation and various kinds of diesel fuels simultaneously. Thus, we have developed on injection system to automatically compensate over the course of its lifetime, which is called i-ART (Intelligent Accuracy Refinement Technology), and adopted IMV (Innovative International Multi-purpose Vehicle) diesel engine (KD model) for Brazil. This engine equipped with the i-ART has successfully passed a new emission regulation and is compatible with the various kinds of diesel fuels used in Brazil.

Diesel Engine Potentials by Hydraulic Tuning of the G4S Solenoid Common Rail Injector with 3-Way Function

The emission legislation for diesel engines, both heavy duty and passenger car diesel engines, have been strengthened in the last years significantly. Currently no further reduction of emission limits is planned but still legislation changes will require further improvements as briefly summarized in this introduction chapter.
