Abstract

The invention relates to a high-pressure tumble air intake testing device for an engine. The high-pressure tumble air intake testing device comprises an air compressor 1, a first pressure stabilizing box 2, an inlet pressure regulating valve 3, a flowmeter 4, a second pressure stabilizing box 5, an air duct pressure sensor 6, a lift sensor 7, an air valve lift adjusting mechanism 8, a to-be-measured cylinder cover 9, an in-cylinder pressure sensor 10, a simulation cylinder 11, a blade anemometer 12, a third pressure stabilizing box 13, a fourth pressure stabilizing box 14 and an outlet pressure regulating valve 15, and the high-pressure tumble air intake testing device for the engine can be used for performing testing research on change rules and influence factors of tumble and flow capacity of a gasoline engine air intake duct under high air intake pressure. The invention further relates to a high-pressure tumble air intake testing method for the engine.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine high-pressure tumble intake test device. Background technique [0002] The airflow movement in the cylinder of the internal combustion engine has a decisive influence on the formation of the mixture and the combustion process, and directly affects the power, economy and other characteristics of the internal combustion engine. The airflow movement in the cylinder is largely affected by the airway flow performance. Therefore, the air intake design is very important. [0003] The airway steady flow test device is the most commonly used test device in the industry to comprehensively evaluate the flow characteristics of the intake port. The existing steady-flow airway test device mainly consists of an air extractor, a vacuum regulating valve, a pressure-stabilizing box, a simulated cylinder liner, a vortex meter and a flow meter. The measurement adopts the con...
