Problems solved by technology

Since the compressor sucks in air and compresses it, the amount of air supplied to the combustion chamber is often greater than the amount of air required to drive the turbine, and the air energy is not fully utilized, which in turn leads to waste of high-pressure gas energy.
The turbocharger performance test bench with this structure cannot make full use of the air compressed by the compressor, is inconvenient to make full use of energy, has high cost, and is not energy-saving enough. How to make full use of this part of energy has become an important issue for today's turbocharger benches. important exploration questions

Abstract

The invention relates to a turbocharger test device, in particular to a test stand used for testing self-circulation performance of double turbochargers and provided with a high-pressure gas shunt device. The test stand is characterized in that the gas shunt device is arranged at an outlet end of a gas compressor of a high-flow main turbocharger on a main test stand rack and shunts high-pressure gas compressed by the gas compressor into two pipelines, and gas in one pipeline returns to a main test stand rack combustion chamber through a main turbocharge self-circulation communication valve; gas in the other pipeline passes an auxiliary test stand rack access control valve and drives a low-flow auxiliary turbocharger through an auxiliary test stand rack combustion chamber, and the auxiliary test stand access control valve is switched off after the low-flow auxiliary turbocharger operates stably. According to the test stand, performance testing in an actual state can be simulated really, tests of two different types of turbochargers can be met simultaneously, and the test stand is applied to various operating conditions for test. Besides, the test stand is simple in mechanical structure and easy to adjust, realizes energy conservation and emission reduction, reduces cost and improves the test efficiency.

Description

technical field [0001] The invention relates to a turbocharger test device, in particular to a double turbocharger self-circulation performance test bench with a high-pressure gas splitting device. Background technique [0002] The turbocharger uses the exhaust energy of the internal combustion engine to drive the turbine to do work, increasing the intake pressure of the internal combustion engine, thereby increasing the power of the internal combustion engine, reducing fuel consumption and exhaust pollution. "High efficiency, energy saving, and emission reduction" are the main goals of today's automotive engine technology development. The market demand for turbochargers is increasing. Pure theoretical calculations cannot fully describe the performance of turbochargers, and their performance must be tested through experiments. . Therefore, designing an energy-saving, environment-friendly and high-efficiency turbocharger test bench has become an important topic in the resear...
