TH53778B - Valve timing gear for variable valve timing in the vehicle's internal combustion engine during operation. - Google Patents

Abstract

DC60 (22/03/16) to provide a valve gear for variable valve timing on the engine. Burns the inside of the vehicle while in operation. which can protect the actuator from external forces by No specific shield assembly is required. and the actuator operation noise is isolated. The variable valve timing actuation mechanism (60) is customized to deliver the action. The actuator (61) goes to the slider mechanism (52) to change the valve timing. The internal combustion engine is suspended by the body frame (2) of a saddle-mounted vehicle with cylinders that tilt forward slightly The fuel tank (6) supported on the fuselage (2m) looks like a straddle truss from above, covering the internal combustion engine from above so that the head cover (20) is facing. It approaches the bottom plate of the fuel tank (6) and the actuator (61) is supported on top of the header cover (20) is covered by the fuel tank (6) from the top. and was placed in one position which overlaps the camshaft of the valve system (41) when viewed in the direction of the axis of the cylinder Amends the invention summary 22/03/2016 to provide a valve gear for variable valve timing in the engine.
