Air intake management test system for internal combustion engines

Abstract

The invention relates to the technical field of power machinery and aims to provide an air intake management test system for an internal combustion engine. Including: intake pipe and intercooler, supercharger, and air filter connected in sequence; also includes: vacuum pump or fan connected to the surge tank, the surge tank is connected to the surge tank through the pipeline, and the pipeline A flow meter is designed; a bracket is provided on the top of the steady flow tank, and an eddy current measuring device and a cylinder liner are installed on the support, and the cylinder head and the cylinder liner are tightly fitted to ensure sealing; the valve lift control device is installed above the cylinder liner, and the valve lift control device A displacement sensor is arranged above; the aforementioned intake pipe is installed on the cylinder head and connected to the intercooler through the measuring section; a pressure sensor and a temperature sensor are installed on the measuring section. The invention can flexibly adopt test forms according to different test purposes; the range of air intake flow rate is wide, the controllable range is large, the control method is flexible, and the practicability is strong; and it can be flexibly arranged.

Description

technical field [0001] The invention relates to the technical field of power machinery, and more specifically, the invention relates to an air intake management test system for an internal combustion engine. Background technique [0002] With the increasing number of automobiles in our country, the emission of automobiles has attracted more and more attention from the country and the government. With the increasingly stringent emission regulations, automobile companies have taken a series of measures to improve the performance of the engine so that it can organize combustion as fully as possible, such as variable valve timing technology, multi-valve technology, variable swirl At the same time, a series of advanced post-processing methods are adopted to achieve the purpose of fully controlling emissions. In short, with the stringent national emission regulations and the improvement of market requirements, it is necessary to start from two aspects of the oil supply system and...

Problems solved by technology

They are often isolated from each other, rather than a whole. Many of their design values ​​are selected based on experience, and often only meet their own conditions. There is a lack of research on the overall performance of the intake system, especially the components of the intake system. Study on the matching characteristics between

Moreover, at present, the performance of the whole machine is often used as the basis for overall matching and verification. However, there are many factors affecting the performance of the whole machine, and it is difficult to accurately analyze the impact of a specific intake accessory on the overall performance.
