Abstract (en)
[origin: WO2021165993A1] The present subject matter relates to a power unit with variable valve timing system. The power unit (100) comprises a cylinder head assembly (102). A variable valve timing system provided on the cylinder head assembly (102) comprises a first cam (142) for actuating one or more first valves (132) through a first rocker arm (144) pivotable about a first axis (S-S1)· A secondary cam (152) for selectively actuating the one or more first valves (132) through a secondary rocker arm (154) pivotable about the first axis (S-S1). An engaging unit (145, 160, 162) is disposed about the first axis (S-S1) is configured to selectively engage the secondary rocker arm (154) with the first rocker arm (144). The present invention provides a system with lower inertia due to mass accumulation near to the first axis (S- S') thereby enabling ease of operation and operation at higher speed of the power unit.
