Problems solved by technology

Disadvantages are: troublesome operation, reduced vehicle braking reliability, no power generation, no air conditioning
This method has a good fuel-saving effect and is easy to use. The disadvantage is that it increases the labor intensity and wears out the release bearing of the clutch, which increases the failure rate and thus increases the operating cost of the car. No power generation during taxiing and no air conditioning

Embodiment Construction

[0022] The variable cycle system of the automobile engine is composed of a camshaft (1), a first intake valve rocker arm (5), a second intake valve rocker arm (7), a variable cycle rocker arm (6), a positioning spring (26), Timing piston (10), first synchronous piston (11), second synchronous piston (14), blocking piston (18), return spring (17), rocker arm shaft (8), oil pipe (32), solenoid valve (27), electric motor oil pump (33), voltage stabilizing valve (34), variable circulation control circuit (31) form.

[0023] Such as figure 1 As shown, the camshaft (1) is provided with the first intake cam (2), the second intake cam (4) and the variable cycle cam (3), the rotation direction n shows the variable cycle cam (3) and the first intake cam Corresponding positional relationship between the gas cam (2) and the second intake cam (4).

[0024] Such as figure 2 As shown, the function of the first intake cam (2) and the second intake cam (4) is to respectively drive the firs...

Abstract

The invention discloses an automobile engine variable-cycle system. After an automobile enters a gear engagement sliding state, the system enables a variable-cycle rocker arm and inlet valve rocker arms to be connected together in time to shake, and therefore the inlet valve rocker arms comply with drive of inlet cams and drive of a variable-cycle cam. An engine is changed into a two-stroke cycle from a four-stroke cycle; therefore, under the condition that original driving operation habits of the automobile are not changed, the engine resistance generated during gear engagement sliding can be reduced to the lowest so as to reduce running fuel consumption to the greatest extent, the brake reliability of an original automobile is not influenced, the operation content is not increased, and the power generation efficiency and the air conditioning efficiency can keep at the efficiency during the corresponding automobile speed; and as long as an accelerator pedal or a clutch pedal or a brake pedal is treaded, the engine is automatically changed into the four-stroke cycle from the two-stroke cycle.

Description

1. Technical field [0001] The invention relates to a variable cycle system of an automobile engine, which is used to change the four-stroke cycle operation of the engine into a two-stroke cycle operation when the car is gliding, that is, when the car is gliding, the cycle operation of the engine becomes air suction when the piston descends. , The two-stroke cycle operation of the exhaust when the piston is moving upwards 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, in the running state of known automobiles, especially for heavy-duty vehicles, the coasting state accounts for more than 30% of the total running time or mileage of the car. The methods of reducing engine resistance in the coasting state include: coasting at idle speed and forced idle speed into gear Coasting, coasting in ...
