Abstract

The invention relates to a variable intake valve system for an automobile engine. The system enables the engine without a valve rocker arm to automatically change from a four-stroke cycle working state to a two-stroke cycle idling state when the car is in gear and slides. When the gear is in the sliding state, it can automatically change from the two-stroke cycle idling cycle state to the four-stroke cycle working state, so that the car has a lower sliding resistance in gear, and at the same time does not reduce the reliability of the car brake, and does not need to change the normal driving operating habits.

Description

1. Technical field [0001] The invention relates to a variable intake valve system of an automobile engine. Its function is to make the four-stroke cycle operation of the engine become a two-stroke cycle operation when the car is in gear and coasting, that is, when the car is gliding, the engine cycle becomes a piston cycle operation. Inhale when going down, and exhaust when the piston moves up. The two-stroke cycle operation can automatically reduce the engine resistance when the car is gliding, so as to reduce the driving fuel consumption without changing the braking efficiency and reliability of the original car. 2. Background technology [0002] At present, the known automobile engine has three technical states in the sliding state of the automobile in gear, one is the forced idling state; the other is the idling state of stopping fuel supply; . Above-mentioned technical state all exists the technical defect that engine running resistance is big, fuel consumption is high...
