A new 2.2L 4-cylinder diesel engine has been developed to comply with the EURO-IV regulations. This engine will be utilized in the ACCORD model to be marketed in Europe from the early of 2004. The engine has the following distinctive features:
The engine is provided with a 1600 bar second-generation common rail system and combustion has been optimized. In addition, the combination of a continuously variable swirl control valve, EGR cooler and De-NOx catalyst has enabled the engine to clear the EURO-IV requirements.
Adoption of engine structure and layout technologies including a lightweight aluminum cylinder block (manufactured using a new production process) and roller chain has significantly reduced weight and increased compactness.
Adoption of advanced combustion technologies, a variable turbo and low-friction technologies, including an offset crank, has enabled a balance of both high fuel efficiency and power output at the top of this class.
Combustion control and increased structural rigidity result in quietness rivaling that of a gasoline engine.
The development concept stressed a powerful, high-quality and refined diesel engine, and these technologies have enabled its full realization. This paper presents an overview of the newly developed diesel engine and discusses its core technologies.
