Abstract

The invention provides an electronic variable valve timing system function testing device applied to the technical field of variable valve timing system testing. In the electronic variable valve timing system function testing device, a drive motor (2) is connected with an engine crankshaft (5), a cam shaft speed sensor (11) is connected with an acquisition control module (9), an adjustment motor (6) is connected with a motor control component (8), the motor control component (8) is connected with the acquisition control module (9), the acquisition control module (9) is connected with a rotational speed torque sensor (10), and the drive motor (2) is connected with the acquisition control module (9). The electronic variable valve timing system function testing device and a performance test method of the invention can accurately and quickly simulate the actual working conditions of the electronic variable valve timing system used in the engine to judge the product performance of the timing system and contribute to performance optimization.

Description

technical field [0001] The invention belongs to the technical field of testing variable valve timing systems, and more specifically relates to an electronic variable valve timing system function testing device. Background technique [0002] The variable valve timing system (VVT) can realize timing control on the opening and closing of the intake / exhaust valves of the engine, improve the output torque and power of the engine, improve fuel economy and effectively reduce emissions. However, the traditional hydraulic phase regulator needs to establish a certain unlocking oil pressure to adjust the engine valve timing, which means that the hydraulic VVT does not work when the engine is idling or at extremely low temperature; the traditional hydraulic VVT system adjustment The angle is limited, usually the maximum adjustment angle is 35 degrees camshaft angle. Electronic variable valve timing system (EVVT) products are composed of DC brushless motor, controller and gear reduction...
