Abstract

The utility model relates to a universal fuel-saving device with a variable rocker under an engine cylinder, belonging to accessories of gasoline engines. The utility model is a variable rocker cylinder stopping device made by an integral rocker changed to two half body rockers, the engine can be operated normally or operated in cylinder stopping mode according to the operation requirement. The utility model can be controlled by a people or an automatic device. The utility model has the advantages of simple device, low cost, convenient installation and operation, few pollution and no need to change the structure and layout of the engine. The structure of the utility model makes the engine operate with the variable cylinder and saves lots of fuel.

Description

Universal fuel-saving device with variable rocker under engine cylinder cutting-off state

Technical field is a gasoline engine part under the utility model---rocking arm.

At present, a large amount of gasoline engine cars is arranged all over the world, because the characteristics own and the structure of automobile, its power---petrol engine has higher reserve capacity, constantly change because of vehicle operating and load state again, make motor not waste a lot of fuel with best power and high-efficiency operation.According to automobile operating state and load variations, the PSD Partical Shut Down that makes motor car engine is a fuel saving method preferably.This method has been carried out a large amount of research abroad, produced multiple deactivation apparatus, they respectively possess some good points; But many defectives are arranged also: the one, complex structure, part is many, makes inconvenience; The 2nd, deactivation apparatus will be changed engine components, only suitable particular type motor, and versatility is bad.Domestic, have only two kinds of deactivation apparatus at present, and complex structure, also need assisting agency.

Reference: " external automobile ", " automotive engineering ", " driving skills art automatically " Japanese.Auto Mobile English.No. 85200450, Chinese patent.

The purpose of this utility model provides a kind of novel, and is widely applicable, cheaply, do not change the motor cylinder deactivation energy saving device of engine structure and layout.

Principle of the present utility model is the active force of change rocking arm to valve, and valve can normally be opened and closed, and can perseverance close again.Rocking arm is a rod member, a rod member of fixing can be become two movable rod members, and rocking arm just can change like this.The power of control change is spring force and electromagnetic force.The motor proper functioning, valve normally opens and closes, and pin locks arm, and spring is to the pin application of force.When electromagnetic force was pulled out pin hole with pin, rocking arm became the variable arm that shakes, though the energy proper functioning, can not be to the valve application of force, the valve-closing cylinder deactivation.The control of deactivation apparatus can be by people or robot device control.

With reference to figure (1) plan view, figure (2) is the amplification profile of figure (1), and the structural feature and the working procedure of this device is described.

This device is mainly by iron core (1), coil (2), spring (3), pin (4), pin hole (5), front arm (6), rear arm (7), pin (8), torsion spring formations such as (9), and iron core (1), coil (2), spring (3), pin (5) constitute the actuator of cylinder deactivation and proper functioning.Pin (4) and pin (8) are connected into whole rocking arm with front arm (6) and rear arm (7).One end diameter of pin (4) is littler than the other end diameter, and iron core (1) has two holes that diameter is identical and relative on the two ends, and coil (2) is installed in the two ends of iron core (1).All part all is installed on the rocking arm.

When the motor proper functioning, front arm (6) and rear arm (7) are connected for whole by pin (4) and pin (8), and valve normally opens and closes, the whole cylinder proper functioning of motor.

When motor needs the part cylinder deactivation, have in the coil (2) to produce elastic force that magnetic force overcomes spring (3) behind the electric current with pin (4) sucking-off pin hole (5), pin (4) and rear arm (7) are broken away from, rocking arm becomes two activity half arms, can not be to the valve application of force, valve can not breakdown.At this moment cylinder is a pneumatic spring.

Rocking arm is an intermittent motion mechanism, and therefore, pin (4) is easily with the connection of rear arm (7) with separating, and can not produce strong shock and vibration, and the rocking arm after the repacking can satisfy motor fully to the rocking arm performance requirement.

The current switching of coil (2) can be by people or robot device control.

This apparatus features: the one, volume is little, and is in light weight, simple in structure, and cost of production is low; The 2nd, need not change the structure and layout of motor, be applicable to existing or produce in motor install; The 3rd, operation and installation are convenient, all parts all rocking arm originally on one's body; The 4th, action is accurate, and speed is fast, and motor can be selected various cylinder deactivation schemes, as stops 1 cylinder, 2 cylinders etc.; The 5th, engine consumption reduces more than the 10%-30%, the fuel saving ratio height.

The structure of this device can be applicable on the rocking arm of motor of the valve mechanism of side and overhead cam valve mechanism.

Claims

1, a kind of adjustable cylinder deactivation rocker arrangement, it comprises pin, the pin of front arm, rear arm, series connection two arms and the electromagnet that is made of coil and iron core, it is characterized in that: pin constitutes the stepped cylindrical body by two different garden posts of diameter, one section that diameter is little is with spring, one section that diameter is big is inserted in the pin hole, coil is around an end of hollow iron core, and one section that the pin diameter is little is inserted in the iron core;

2, according to the described adjustable cylinder deactivation rocker arrangement of claim (1), it is characterized in that: be with on the pin and make rocking arm be tight against the torsion spring of valve.
