Crane and method and system for controlling flameout of engine

Abstract

The invention discloses a method for controlling flameout of an engine. The method comprises the following steps: S11, detecting whether the engine is in an idling condition and entering a step S12 if the engine is in the idling condition; S12, detecting whether a vehicle has an operation signal, entering a step S13 if the vehicle has the operation signal and entering a step S14 if the vehicle has no operation signal; S13, controlling the engine to be kept in the idling condition; and S14, controlling the flameout of the engine. When the method detects that the vehicle has the operation signal, no control is performed on the engine to flame out. Thus, other operations on the vehicle are considered when the engine is controlled to flame out; in order to guarantee the normality of the operations, the engine is controlled to be kept in the idling condition; and when no operation signal is available, the engine is controlled to flame out, so that long-term idling of the engine can be avoided, and normal operation of the vehicle is not affected. The invention also discloses a system for controlling flameout of the engine and a crane with the system.

Description

technical field [0001] The invention relates to the technical field of engine control, more specifically, to a crane, a method and a system for controlling engine flameout. Background technique [0002] The engine is one of the main driving parts of the vehicle. The vehicle enters the working state under the drive of the engine. After the engine is turned off, the vehicle will lose power and then stop. When the driver is driving the vehicle, he often adjusts the transmission to neutral to keep the engine in an idle state. [0003] During the driving process of the vehicle, due to the driver's lack of understanding of the normativeness of the vehicle's driving, it often occurs that the engine is idle for a long time. When the engine is in the idling condition, it not only wastes a lot of fuel, but also causes greater wear and tear on the engine and shortens the working life of the engine. In the automotive field, in order to solve the above problems, a hardware circuit can ...

AI Technical Summary

Problems solved by technology

[0004] However, because the hardware circuit controls the engine flameout by judging whether the vehicle is stopped, and in some occasions, the engine needs to be kept at idle speed for related debugging. If the hardware circuit is used to control the state of the engine, the above debugging operation will not be realized. , affecting the normal operation of the vehicle

[0005] In addition, the above-mentioned hardware circuit is mainly used in the field of automobiles, and in construction machinery equipment, because the circuit of the equipment itself is relatively complicated, if the hardware circuit is added, the circuit of the equipment will be more complicated
