DEVICE FOR TESTING LOW-POWER EXTERNAL COMBUSTION ENGINES

摘要

The proposed device for testing low-power external combustion engines contains a pump, a vacuum manometer, a pressure transducer, and a direct-recording unit. The working chamber of the pressure transducer is coupled with the cavity of the cylinder of the engine. In the chamber, an elastic diaphragm with a movable contact is installed. The pump and the vacuum manometer are coupled with the working chamber of the pressure transducer. The direct-recording unit contains a drum, which is coupled with the flywheel of the engine, and a pen, which is coupled with the pointer of the vacuum manometer.
