Title:
METHOD FOR DETERMINING GAS RELEASE QUANTITY IN GAS RELEASE VALVE, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/165589
Kind Code:
A1
Abstract:
A method for determining a gas release quantity in a gas release valve and a device. The method comprises: acquiring a pressure value collected by an exhaust pressure sensor of an engine; determining a first pulse pressure value on the basis of a first pulse pressure coefficient and the pressure value, and determining a second pulse pressure value on the basis of a second pulse pressure coefficient and the pressure value, wherein the first pulse pressure coefficient and the second pulse pressure coefficient are both determined by utilizing the rotational speed of the engine and the fuel injection quantity of the engine; and determining the gas release quantity of a gas release valve by using a third pulse pressure value obtained via the first pulse pressure value and the second pulse pressure value.
