Abstract
In the conventional homogeneous-charge spark-ignition engine, fixed lift characteristics and timings for opening and closing of the intake and exhaust valves compromise efficiency and maximum power. In order to minimize the compromise, numerous variable-valve-actuation (VVA) systems have been proposKeywords
