Problems solved by technology

[0004] This traditional fixed-point limit method for diesel injection pump idling fuel supply has always been regarded as the only engine idling point limit method. Idle fuel consumption is unavoidable for common operating conditions where push driving is not necessary

Embodiment Construction

[0011] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0012] In the accompanying drawings, the engine speed sensor is equipped with a movable member that has a corresponding action relative to the changing speed information; the load control lever of the diesel injection pump controls the fuel supply and is linked with the accelerator pedal; when the diesel injection pump is set Under the premise of the minimum fuel supply at the idling point that can maintain the minimum engine speed and stable normal operation, the information of the engine speed change during the vehicle running is transmitted to the speed sensor device, and the corresponding components generated by the speed change are used to control the diesel injection. The load control lever of the pump implements the dynamic limit of fuel supply and non-fuel supply; during the driving process of the vehicle, when the accelerator pedal is stepped on, t...

Abstract

The invention discloses an oil saving method for a diesel automobile, and its technical solution has key points of: transmitting engine speed variation information to a speed sensing device with movable component in the automobile operating course, using corresponding component action caused by speed variation to implement oil-feed or not-oil-feed dynamic spacing for the load control level of a diesel jet pump for controlling oil quantity, thus not consuming the oil in all ordinary working conditions (including level roads and slopes) of forced running by vehicle inertia. The invention is easy to implement and does not influence normal operation of a driver and normal running of the vehicle; it has obvious oil-saving effect, and can assure enough brake air and illumining electricity.

Description

technical field [0001] The invention relates to the technical field of automobile energy saving, in particular to a fuel-saving method for a diesel automobile. Background technique [0002] When the car is started but not running, the speed at which the engine runs normally at the lowest speed is called free idling; after the vehicle is running, due to some special operating conditions in the driving process, the engine speed that is forced by the inertia of the vehicle itself is called forced driving. Idle speed, the fuel consumption of the engine in the above two idling conditions is called idling fuel consumption. [0003] Since different vehicle engines have different idle speed performance requirements, the traditional method is to set the minimum idle fuel supply of the automobile engine by using a special idle speed limit adjustment screw pair at a specific position of the diesel injection pump to control the fuel supply of the pump. The fi...
