Air intake management and test system for internal combustion engine

Abstract

The invention provides an air intake management and test system for an internal combustion engine, belonging to the technical field of the power machinery. The air intake management and test system comprises an air intake pipe, an intercooler, a pressurizer, an air filter and a vacuum pump or a blower; the intercooler, the pressurizer and the air filter are communicated with each other in sequence; the vacuum pump or the blower is connected with a pressure stabilizing tank; the pressure stabilizing tank is connected with a current stabilizing tank through a pipeline which is provided with a flowmeter; a support is arranged on the top of the current stabilizing tank; a vortex measuring device and a cylinder sleeve are arranged on the support; a cylinder cover and the cylinder sleeve are sealed by interference fit; an air valve lift range control device is arranged above the cylinder sleeve; a displacement sensor is arranged above the air valve lift range control device; the air intake pipe is arranged on the cylinder cover and is connected with the intercooler through a measure section; and a pressure sensor and a temperature sensor area arranged on the measure section. The air intake management and test system can flexibly adopt the test form according to different test purposes, has wide air intake flow rate range, can be controlled in a wide range with a flexible method and can be arranged flexibly and is very practical.

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.
