Abstract

The invention discloses an engine variable valve timing system performance testboard, relating to an engine variable valve timing system performance test device. The invention aims to solve the problems of engine variable valve timing system performance detection and has simple structure, strong universality, easier installation and more accurate and reliable measured data. The invention has the technical scheme that the testboard comprises a cylinder cover. A cam shaft is arranged in the cylinder cover; the front end of the cam shaft is connected with a phase shifter and the rear end thereof is connected with a cam angle sensor; a valve assembly is arranged in the cylinder cover and actuates along with the rotation of the cam shaft; the cylinder cover is provided with an engine oil control valve; a drive motor drives a crankshaft sprocket through a transmission synchronous belt; the crankshaft sprocket drives the phase shifter through a chain; a crankshaft position sensor is arranged below the crankshaft sprocket; and hydraulic oil enters from the oil inlet arranged on the cylinder cover and flows out from the oil outlet. The invention is mainly applied to the performance test of an engine variable valve timing system.

Description

technical field [0001] The invention relates to a performance testing device for an engine valve timing system. technical background [0002] The variable valve timing system is widely used in new automobile engines, which can increase engine power and torque, and reduce fuel consumption and exhaust emissions. Variable valve timing can optimize valve characteristic parameters, improve engine and exhaust performance, and better meet the requirements of power, economy, and exhaust emissions of the engine at high and low speeds, high loads and light loads, and improve the overall performance of the engine. Comprehensive performance. Nowadays, variable valve technology has become one of the key technologies to measure engine performance. Through the research and innovation of variable valve technology, internal combustion engine manufacturers are gaining stronger and stronger competitiveness. [0003] The continuously variable cam phaser system uses the internal oil pressure t...
