Project: Common Rail - Fuel Injection in Diesel Engines
Contact: Senior Research Scientist Pekka Rantanen
The aim of the study is to control combustion in the diesel engine with the aid of an exactly controlled fuel spray in a way that high efficiency and small emissions are achieved. Characteristics and control alternatives of present electrically controlled systems and are studied, and tools for the dimensioning and choice of diesel-injection systems of various types and sizes will be developed by using mathematical modelling and simulation as well as measuring.
Injection systems based on new common-rail technology and electrical control systems governing the entire engine are the key components to reach the object.
A fast injection control valve for medium speed engines is one of these components under development. Valve is based on a piezoelectric actuator.
Project is led by Tampere University of Technology/IHA (Institute of Hydraulics and Automation) and industrial partners are Wärtsilä Corporation, Sisu Diesel Inc, Mitron Oy and Tampere Multivisions Oy
Project is part of national ProMOTOR technology programme 1999-2003. The project is being supported by the National Technology Agency TEKES.
