Abstract

The invention discloses a three-valve overhead single-camshaft engine gas distribution system. According to the system, each air cylinder is provided with an air inlet valve and two exhaust valves, when an automobile runs, the system enables an air inlet supercharged engine to work in a four-stroke circulation state, and the sectional area of an exhaust channel is increased so that exhaust resistance can be reduced to reduce power loss caused by exhaust; after the automobile enters a sliding state with a gear, the four-stroke circulation operation of the engine can be changed into the two-stroke circulation operation of air suction and air exhaust, so that the operation resistance is reduced. When the automobile enters the deceleration operation with the gear, the engine is changed into anair compressor, four-stroke circulation operation is changed into circulation mode operation of an intake stroke (intake valve intake), a compression stroke (exhaust valve deflation when the compression stroke is about to be ended), a vacuumizing stroke (exhaust is closed shortly after an original expansion stroke is started) and an exhaust stroke (exhaust valve exhaust), so that the operation resistance of the engine is increased to generate brake slow-acting energy.

Description

[0001] 1. Technical field [0002] The invention relates to a gas distribution system for a three-valve overhead single camshaft engine. Its function is to make the intake boosted engine run in a four-stroke cycle when outputting power, and to have a larger exhaust passage. Cross-sectional area and smaller exhaust power loss; when the car is sliding with gear, the engine with intake boost can be changed from four-stroke cycle operation to "intake stroke (intake valve intake), exhaust stroke (intake valve exhaust), intake stroke (intake valve intake), exhaust stroke (exhaust valve exhaust)" two-stroke cycle operation, in order to reduce the engine resistance when the car is sliding, so that the original car system is not changed. Reduce driving fuel consumption under the premise of dynamic performance and reliability; and when the car is running with gears and decelerating, the engine can also be automatically turned into an air compressor, with "intake stroke (intake valve intak...
