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 motor vehicle energy-saving method is that action mechanism is equipped in engine, when motor vehicle electric-controlled system does not test fuel feeding accelerator and engine is on the state of anti-draw, action mechanism with valve lever driven by order moves a certain distance toward burning chamber, and this make valve does not complete closed in the reciprocating movement of valve level; when motor vehicle electric-controlled system tests that accelerator has already fuel-feed, braking or engine speed already reached to approach idle speed, sending order make action mechanism reset, valve lever is also reset by valve spring. The remarkable effect of the present invention is: eliminating anti-draw of oil supply condition in running motor vehicle, motor vehicle moves more distance depending on inertial property during the periods of stopping oil supply, so energy-saving and economy effect are achieved.

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...
