Embodiment Construction

[0073] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0074] The turbocharger acceleration testing device of the present invention measures the acceleration of the turbocharger when the turbocharger is in a simulated working state (the supercharger is installed on a test stand).

[0075] The turbocharger acceleration testing device is used to measure the turbocharger acceleration when the supercharger is in a simulated working state (the supercharger is installed on the test stand). In order to make the simulated working state of the supercharger more consistent with the actual working state of the supercharger installed on the engine, the turbocharger 21 should be given a certain energy (temperature, pressure, mass flow) gas to drive the turbocharger 21 , make its rotating speed start from 0, accelerate to rated rotating speed (or arbitrary rotating speed), also can make the turbocharger 21 acce...

Abstract

The invention discloses an acceleration performance evaluation test method and a test apparatus of a turbo-charger. The acceleration performance evaluation parameters of the turbo-charger are obtained according to formula computing by measuring the parameters of the turbo-charger such as pressure, temperature, flow rate and rotate speed. The invention has the following advantages: the acceleration performance of the turbo-charger is accurately and conveniently evaluated by measuring and computationally analyzing acceleration parameter Acnp, and provides measuring means and judgment basis for improving and optimally designing the turbo-charger, compressor impeller and rotor system and improving the acceleration performance of supercharger.

Description

technical field [0001] The invention relates to an acceleration performance evaluation test method and a test device, in particular to a turbocharger acceleration performance evaluation test method and a test device. Background technique [0002] Turbocharging is one of the main directions of the development of piston internal combustion engine technology in the world today, and it is the most important way to strengthen the engine. The engine adopts turbocharging technology, which can greatly increase output power, increase volume and weight power density, improve economy, save energy, improve exhaust pollution, reduce noise, and compensate for power loss in plateau environments. Without changing the basic structure of the engine, compared with a naturally aspirated engine, a turbocharged engine can increase power by 30% to 100%, reduce fuel consumption by 5% to 10%, and reduce emission pollution by more than 10%, while the cost only increases by 8. %~10%, the weight incre...
