Abstract

In fall 2003, Honda introduced a passenger vehicle diesel engine to the European market. During the development of this engine, research was conducted on combustion technologies to reduce fuel consumption, combustion noise and emissions.By adopting the pilot injection while also advancing the start of main combustion event, fuel consumption and combustion noise are both lowered, but emissions performance was not improved. Dispersion of the air-fuel mixture and the extension of the appropriate period for dispersion ensured a lean local air-fuel ratio and resolved the emissions issue.The use of these combustion technologies has enabled fuel consumption and emissions out of engine to be reduced with no increase in combustion noise. Fitted in a 1590 kg equivalent inertia class vehicle in combination with the catalyst, the vehicle satisfied the 2005 European diesel exhaust emissions standards (EURO IV), and achieved a low fuel consumption of 5.4L / 100 km and superb quietness.
