Development of High-performance and Low-emission Direct Injection Gasoline Engine

Article of Honda R&D Technical Review Vol.16 No.1

Summary

Honda has developed the first-ever 2.0L i-VTEC I direct injection gasoline engine employing a center injection system in which a high-pressure fuel injector is located in the center of the combustion chamber. This engine significantly improved fuel economy and emissions performance. Optimization of in-chamber fuel flow through redesign of piston shape and the spray characteristics of the high-pressure fuel injector and the application of VTEC has enabled the achievement of stable combustion of a stratified ultra-lean air-fuel mixture. Due to VTEC mechanism and the continuous variation of camshaft phase enabled by VTC, the engine has achieved top-class power for a high fuel economy engine. The new engine is fitted in the 2004 model Stream, and in combination with the CVT employed in the vehicle has enabled the Stream to achieve a low fuel consumption figure of 15.0 km/l in Japanese 10-15 mode. A large amount of EGR and a high-performance lean NOx catalyst to reduce emissions has further enabled the Stream to become the first vehicle with an engine employing ultra-lean stratified charge combustion to achieve an emissions level of only 25% of the level stipulated by the Japanese 2000 emissions regulations and obtain Ultra Low Emission Vehicle (ULEV) certification.
