Abstract
A new lean-burn engine was developed as a 4-cylinder power plant for Hondas 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.
