Abstract

The invention relates to a rocker arm auxiliary unit applied to an engine cylinder head. The rocker arm auxiliary unit comprises a check mechanism, and a contact portion arranged on a second air inlet rocker arm. The second air inlet rocker arm is further provided with a check end capable of making contact with the check mechanism, and the contact portion is arranged at the check end. The check mechanism comprises a framework which is provided with a containing portion and detachably arranged above a cam shaft seat, at least one elastic element located at the containing portion, and a check plunger capable of making contact with the second air inlet rocker arm below the check plunger. Convenience of maintenance engineering of the check mechanism is improved in this way.

Description

technical field [0001] The present invention relates to a rocker arm auxiliary unit for the engine cylinder head, especially the check mechanism used on the second intake rocker arm (high lift) of the intake rocker arm group, which is used for maintenance engineering convenience Rocker auxiliary unit for the engine cylinder head. Background technique [0002] In the technical field of engine variable valve lift mechanism, the applicant created the invention patent case of TWI479076 "Variable Valve Lift Mechanism of Engine". This provides a better variability of the engine valve lift. [0003] However, in the invention patent of TWI479076 "Variable Valve Lift Mechanism of Engine", the foot support mechanism A is arranged towards the direction of the cylinder body, that is to say, the foot support mechanism A is arranged under the intake rocker arm , thus causing the maintenance difficulty of the foot support mechanism A. Therefore, the applicant further made further improv...
