Abstract
The invention relates to a simple and effective automobile fuel-saving technology. A gear detection device is used to detect the gear shift in the running process of an automobile, a central control device is used to carry out judgment, and an idle speed control device is used to adjust the idle speed of the automobile. By using the invention, the idle speed can be reasonably and automatically adjusted according to the gear shift of the automobile: when the automobile is in neutral gear or parking gear, the idle speed of an engine is lowered to reduce the fuel loss; and when the automobile is in running gear or reverse gear, the idle speed is raised for recovery, so that the engine can return to a normal working state without affecting the normal running of the automobile. Thus, by reasonably adjusting the idle speed, the environmental protection effects of fuel saving and pollution emission reduction can be achieved.
Description
Technical field the present invention relates to a kind of vehicle fuel saving technique.
Consumption oil was bigger when the background technique auto idle speed was high, particularly went in the city of traffic congestion, often run into traffic congestion, etc. red light, stand in a long queue, these situation can not be stopped working again, can only neutral idle idle running, fuel oil wastes.Turn down idling and can reduce fuel oil waste naturally, but low idling particularly can cause job insecurity during low speed driving at cruising, even dead fire.Existing technology does not solve this contradiction.
Summary of the invention the present invention seeks to disclose a kind of technology that reaches fuel-economizing through the control idling.
Technical characteristics of the present invention is the gear change that detects automobile running through gear detection device, is judged by the center control gear, when vehicle is in neutral gear or park, engine idle is turned down, to reduce the fuel oil loss; And when shelves or reverse gear are gone in the vehicle entering, heighten the recovery idling immediately, and make motor recover normal working, do not influence automobile normal running.
The present invention reasonably adjusts idling automatically according to the gear change of automobile: when vehicle is in neutral gear or park, engine idle is turned down, to reduce the fuel oil loss; And when shelves or reverse gear are gone in the vehicle entering, heighten the recovery idling immediately, and make motor recover normal working, do not influence automobile normal running, reach the environment protection effect of saving fuel oil, reducing disposal of pollutants like this through reasonable adjusting idling.
Appended drawings is a fundamental diagram of the present invention.
Embodiment describes the embodiment of the invention with reference to the accompanying drawings:
Among the figure, gear detection device is used to detect the range state of automobile, and present embodiment only detects its neutral gear and park; Can be directly connected in the gear display circuit for the automobile that has gear to show and to obtain gear signal; This signal is delivered in the central control circuit, these signals is carried out logic judge, when automobile is in neutral gear and park; The control signal of the low idling of output, otherwise the control signal of (just automobile is in go shelves or reverse gear) output high idle speed.Idle speed controller is used for this control signal is carried out; Can adopt an electromagnetic valve, thereby control the mode that air inflow is controlled idling through closure, automobile is with normal idling work during unlatching; Automobile reaches the fuel-economizing purpose with low idling work when closing.
