Abstract
Most currently produced lean-burn engines can achieve good fuel economy, but must be further developed to gain better vehicle performance and driveability. Honda has developed a new lean-burn engine which incorporates 3-stage variable valve timing and lift mechanism, swirl promotion at low engine speed, and a new intake port configuration. This engine generates approximately 40% more power over our current lean burn engine and improves the dynamic performance of the vehicle. At the same time, it maintains a fuel consumption level equal to that of the current engine.
