Abstract
The utility model discloses a 'cylinder-changing device for engine ' which belongs to the technical field of internal-combustion engine. The art is to cease the operation of partial cylinder according to the load factor of the engine, and alter the displacement capacity of the engine so as to realize energy-saving. The cylinder-changing device for engine adopts the method of directly controlling a valve tappet, to control a variable push rod with an electromagnetic coil, and the original device of the engine doesn't need to be altered. The utility model has the advantages of simple structure and low cost, and can either be used for designing the novel model of vehicle or rebuilding the old model of vehicle.
Description
The utility model belongs to technical field of internal combustion engines.Be a Rate of load condensate, change the technology of engine displacement according to motor.
At present, change engine displacement, the inlet and exhaust valve of closed portion cylinder when the low-load rate makes these cylinders become pneumatic spring, and oil-saving effect is remarkable.Therefore the technological scheme that various change cylinders occurred is as (No. 85200450 utility model patents, Beijing car industry technology development center); The former changes Rocker arm assembly triumphant enlightening dish gram V8-6-4 h type engine hs etc. (the complete works of Hubei of Hyundai Motor profit learn a skill publishing house, 132 pages), increases eccentric shaft and reaches the cylinder deactivation purpose.The latter controls rocking arm pivot (axle) point of Rocker arm assembly and realizes cylinder deactivation.But their shortcoming is a complex structure, need be to the Rocker arm assembly of motor, and parts such as cylinder cap, valve-chamber cover are done bigger change and are increased dragging motor.Complex structure, the cost height.
Main purpose of the present utility model is to provide a kind of gas distribution structure and Rocker arm assembly that does not change motor, and realizes that motor becomes the technology of discharge capacity cylinder deactivation.
According to a kind of structure of the present utility model, substantially by variable push rod, base, the device that electromagnetic coil is formed promotes the bayonet lock of variable push rod inside by electromagnetic coil, changes the constraint of bar core and shell, makes to promote valve rocker, and realizes closing cylinder.
According to another kind of structure of the present utility model, this device can be installed in the body, to adapt to the requirement of L-head engine.
According to the utility model, control switch and display unit are installed on the bridge instrumentation dish, control this device by the driver.Obviously also can use the method for automatic control instead.
Accompanying drawing 1～4th, an application example of the present utility model is applicable to 492 type petrol engine.The 4-3 that this device is finished becomes cylinder.
Accompanying drawing 1 is the side view of this example.
Accompanying drawing 2 is this example I-I sectional drawings.
Accompanying drawing 3 is this example II-II sectional drawings.
Accompanying drawing 4 is control section block diagrams.

This application example is like this work: (9) snap under the effect of (10) in the groove of (8) during automobile normal running, and (7) and (8) are subjected to being constrained to of (9) as a whole. Promoting valve under the effect of (15) opens or closes. (1) in the hole of (2), slides up and down. (6) pushed to the outside by (5).
When the needs cylinder replacing work, as long as open (16), A

2Connect, (3) adhesive (6) produces a lateral forces on (9), and move under above-mentioned effect laterally (9), breaks away from (8), makes (7) and (8) can relative movement, has not had constraint.At this moment (8) can only move up and down in (7) under the effect of (15), can not promote valve rocker, have so promptly realized closing the purpose of cylinder.
When opening (16), (17) are lighted (18) and demonstrate change cylinder state on the bridge instrumentation dishes.
Increase power character at needs, when recovering normal working, as long as close (16), the power supply of (3) is cut off.(6) push the outside under the effect of (5), the lateral force on the bayonet lock (9) disappears, and (9) push (8) under the effect of (10), and snap in the groove of (8).(7) and the constraint of (8) recover, be combined into an integral body, return to the state that does not become before the cylinder, extinguish (18).
The lubricated of this example supplied with by (14) by (13).Whole device is fixed on the cylinder cap fastening screw trip bolt by (4).
Become the result that cylinder is tested according to Beijing car industry technology development center, 4-3 becomes cylinder than 4 cylinder working fuel-economizings 10～16%, and CO and HC discharging significantly descend.This conforms to (seeing patent application specification CN85200450) substantially with test that the author is done on Zhengzhou 130.But the utility model is compared cost with above-mentioned No. 85200450 patents and reduced by 60%, and is easy to install, is not subjected to the restriction of air valve structure.The remodeling that can be used for new car also can be used for the transformation of old vehicle.The characteristics of the utility model maximum are that practicability is very strong.
By the description of above-mentioned application example, the utility model various motors (motivation such as diesel engine are readjusted the distribution in confrontation, must control oil supply system simultaneously) that can be used for simple in structure can be formed 8-6 easily as can be seen, 6-4, and 4-3 etc. become the cylinder control system.Obviously the utility model can have different structures to different types.Also different remodeling and mounting point can be arranged.
