Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] In order to realize the energy saving of the motor vehicle, the present invention is provided with an action mechanism in the engine. When the electric control system of the motor vehicle detects that the throttle is not supplied with oil and the engine is in the reverse drag working condition, an instruction is issued to make the action mechanism drive the valve stem toward the combustion chamber. direction to move a certain distance, so that the intake and exhaust valves cannot be completely closed. When the electronic control system of the motor vehicle detects that the throttle resumes fuel supply, brakes or the engine speed drops to close to idle speed, the action mechanism resets, and the valve stem is in the position of the valve spring. It is also reset under the action. The normal reciprocating movement of the valve stem under the action of th...

Abstract

A method for energy saving of a motor vehicle, which is to install an action mechanism in the engine, and when the electric control system of the motor vehicle detects that the throttle is not supplied with fuel and the engine is in reverse dragging mode, an instruction is issued to make the action mechanism drive the valve stem to the direction of the combustion chamber Move a certain distance so that the valve stem cannot completely close the valve during the reciprocating movement; when the electronic control system of the motor vehicle detects that the throttle resumes fuel supply, brakes or the engine speed drops to close to idle speed, it sends an instruction to reset the action mechanism, and the valve stem The valve spring also resets accordingly, and the action mechanism is a rack-and-pinion, eccentric shaft or hydraulic structure. The remarkable effect obtained by the invention is: the anti-drag phenomenon in the state of no oil supply is eliminated during the running of the motor vehicle, and the distance traveled by the inertia of the motor vehicle is longer when the engine stops fuel supply, thereby achieving the effect of energy saving and fuel saving.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle energy saving, and in particular relates to a method for controlling the engine under specific working conditions to achieve energy saving of the whole vehicle. Background technique [0002] When the motor vehicle is started, the speed that maintains the engine running stably and normally at the lowest speed is called free idle speed; while in some special states during the driving of the vehicle, such as a long downhill, the engine speed when the vehicle is forced to drive by its own inertia is called forced idle speed . The fuel consumption of the engine under the above two working conditions is collectively referred to as idling fuel consumption. The fuel consumption at free idle speed is necessary to maintain the minimum operation of the engine; while the fuel consumption at forced idle speed is completely unnecessary, because at this time, the vehicle relies on its own inertia to forci...
