Abstract

A 660cm3 3-cylinder engine has been developed for the new model of the Honda Life. The basic structure of the engine has been redesigned to achieve improved environmental performance, increased compactness and weight savings, and a higher level of quietness.The development concept was to produce an engine that excelled under normal driving conditions. To respond to the high frequency of high engine loads and engine speeds in minicars, the i-DSI engine employs a short stroke to reduce friction. The use of i-DSI twin plug ensures rapid combustion, enabling fuel economy and output to be increased through the use of a high compression ratio.The innovations outlined above have increased torque by 7% under normal driving conditions, and enabled the achievement of a class-topping fuel economy of 19.8 km/L in Japanese 10-15 mode. The increased idling fuel economy achieved by improved combustion and reduced emissions and NV make the new engine an extremely high-quality unit.
