Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] The turbocharger acceleration performance test device of this embodiment is to modify the fuel system of the existing test bench, that is, to add a set of fuel transient state that can adjust the fuel oil entering the combustion chamber 4 on the supply adjustment device of the original test bench fuel system. Variation of the device to achieve the acceleration performance test of turbocharger 8.

[0021] Specifically, such as figure 1 As shown, the supply regulating device includes a fuel tank 1, a fuel pressure pump 2, a regulating valve 3, a combustion chamber 4, a delivery pipeline 7, a turbocharger 8, a parameter measuring instrument and a data acquisition system, and the fue...

Abstract

The present invention provides a turbocharger acceleration performance testing device, on the premise of not changing the original fuel system regulation function during the turbocharger performance test, a set of devices capable of adjusting the transient change of fuel entering the combustion chamber is added . It can realize the acceleration performance test research of the turbocharger, and is applicable to the turbochargers of different specifications, and can ensure the repeatability of the test results.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas turbocharging, and in particular relates to a testing device and a measuring method for an acceleration performance test of a turbocharger. Background technique [0002] The turbocharger is an important part of the vehicle engine power system, and the acceleration of the turbocharger is the key to the transient response of the engine. The moment of inertia of the turbocharger rotor is the decisive factor for the acceleration response capability of the turbocharger. Therefore, the current research direction at home and abroad focuses on reducing the moment of inertia of the turbocharger rotor without affecting the efficiency and strength of the turbocharger. And the smaller turbine flow area is used as much as possible to improve its acceleration, mainly using low-inertia turbine rotors, small damping ball bearings and variable-section turbochargers. [0003] At present, there is no clear and ...
