AI Technical Summary

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 circulation system of the automobile coasting engine is composed of a cylinder head (17), a camshaft (1), a first lifter (4), a second lifter (5), a first lifter guide (31), and a second lifter guide (32), exhaust valve rocker arm (6), variable cycle rocker arm (7), positioning spring (19), rocker arm shaft (8), timing piston (10), synchronous piston (18), blocking piston ( 14), return spring (15), machine oil pipe (27), pressure regulator valve (29), solenoid valve (25), electric motor oil pump (30), variable cycle control circuit (24) form.

[0023] Such as figure 1 Shown, cam rotation direction n, there is the relative relation of exhaust cam (2) and variable circulation cam (3) on camshaft (1).

[0024] Such as figure 2 As shown, the exhaust cam (2) corresponds to driving the first tappet (4), and the variable cycle cam (3) corresponds to driving the second tappet (5)

[0025] Such as image 3 As shown, during the exhaust stroke, the first lifter (...

Abstract

The invention discloses an engine cycle-changeable system for automobile coasting. According to the system, under the condition that normal driving habits are not changed, when an automobile is switched to a gear-shifting coasting state, an engine can be automatically switched from a four-stroke cycle to a two-stroke cycle so that the running resistance generated by the engine which is dragged by a driving wheel to rotate can be obviously reduced, and when the automobile is switched to an accelerating or braking state from the gear-shifting coasting state, the engine can be automatically switched from the two-stroke cycle to the four-stroke cycle.

Description

1. Technical field [0001] The invention relates to a variable circulation system of an automobile sliding engine, which can make the automobile have lower running resistance of the engine when the automobile is sliding in gear, so that the automobile has a longer safe sliding distance. Background technique [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 neutral with the engine off, coasting in gear with the engine off, coasting in gear with the engine off, and sliding with the clutch in gear. [0003] Each taxi mode has its own disadvantages: [0004] Idling and neutral coasting, the engine runs at idling speed, this method has a longer gliding distance and better fuel saving effect...
