Problems solved by technology

[0004] But when the engine is in normal running mode, the existing technology still powers the airflow throttle valve, which brings power loss
At the same time, when the engine is in the normal operating mode, the opening of the air flow throttle valve will still change in a small range on the basis of a certain opening, which undoubtedly increases the wear of the air flow throttle valve

Abstract

The invention discloses an air flow throttling valve control method of an engine and related equipment. The method is characterized in that a current working mode of the engine is obtained, when the current working mode is a normal operation mode, the air flow throttling valve of the engine is controlled to be powered off, when the current working mode is a heating mode or a DPF regeneration mode of a particle catcher, the air flow throttling valve of the engine is controlled to be electrified, so that a vehicle can run normally, and meanwhile, the unnecessary electric power loss of the vehicle when the engine is in the normal operation mode and abrasion of the airflow throttling valve are avoided, so that the electric energy of the vehicle storage battery is saved, and abrasion of a transmission mechanism of the airflow throttling valve is reduced.

Description

technical field [0001] The invention relates to the field of engine control, in particular to an engine airflow throttle control method and related equipment. Background technique [0002] On June 22, 2018, my country issued the national standard (standard number GB17691-2018) of "Heavy-duty Diesel Vehicle Pollutant Emission Limits and Measurement Methods (China Phase VI)". The national standard will come into effect on July 1, 2019. my country's pollutant emission requirements for various vehicles, including heavy-duty diesel vehicles, are getting higher and higher, which is conducive to the continuous optimization of my country's natural environment. [0003] In the prior art, vehicle exhaust gas is usually purified by selective catalytic reduction (SCR, Selective Catalytic Reduction) and particle trap (DPF, Diesel Particulate Filter). Since the SCR and DPF have certain requirements on the exhaust gas temperature, the engine of the vehicle sometimes runs in the heating m...
