Abstract

The invention relates to a metering system for fuel of a PT pump fuel injector and a metering method of the metering system. Two kinds of metering systems for fuel of the PT pump fuel injector are provided, wherein the first system comprises a container for containing fuel to be metered, and a controller, and the controller is connected with at least one upper limit liquid level detection device used for detecting the set upper limit height threshold value of the quantity of fuel to be metered in the container, and further connected with a counting device used for counting the number of fuel injection times of the fuel injector. The second system comprises a container for containing fuel to be metered and a controller, wherein the controller is connected with a counting device used for counting the set number of fuel injection times, and further connected with a fuel amount detecting device used for detecting the amount of the fuel which is to be metered and is injected into the container by the fuel injector according to the set number of fuel injection times. The mode of fixing the amount and measuring the number of times is adopted in the first kind of metering system. The mode of fixing the number of times and measuring the total amount is adopted in the second kind of metering system. Both the metering systems can achieve detection on constant volume high-impact and non-continuous small flow of fuel injected by the PT fuel injector.

Description

technical field

[0001] The invention relates to a PT pump fuel injector fuel metering system and a metering method thereof, belonging to the technical field of fuel metering. Background technique

[0002] The application of modern electronic control technology in the engine injection system has greatly improved the engine performance. The fuel injection quantity characteristic of the fuel injector of EFI engine is an important factor to determine the performance of the fuel injector. Therefore, the high-precision and high-efficiency measurement of the fuel injection quantity of the fuel injector is an important part of the technical performance evaluation of the fuel injector, and it is also the basis for fault analysis of the faulty fuel injector. The fuel injection volume test of PT injector mainly detects the precise flow rate under different fuel supply pressures, different speeds, and different load conditions. The impact pressure reaches 1200 atmospheres, 20 times per...
