Abstract

A new lean-burn engine was developed as a 4-cylinder power plant for Honda’s next generation 2L-class vehicle. New mechanisms, such as i-VTEC which combines variable valve timing and lift control and continuously variable camshaft phase control, are applied to this power plant. As a result, a 113kW maximum output and a 186Nm maximum torque were achieved while at the same time a 14.2km/L fuel economy in the 10•15 mode and a 50% reduction over the Japanese 2000 Emissions standards were realized. Further, improved assembly conditions were facilitated by decreasing the weight of the engine by 10kg and the length of the engine by 54mm.
