Gamvdout Diesel Engine Model Physics Experiment Equipment Teaching Instrument Diesel Engine Model Working Principle of Internal Combustion Engine Physical Experiment

Purpose: Used for teaching demonstration of heat engine part of physics class in middle school. Features:It can clearly explain the basic working principle of four-stroke single-cylinder gasoline engine and the main structure of common single-cylinder gasoline engine. The compression ratio of a gasoline engine is generally 5-8, so when the piston rises to the top dead center, a certain gap is left proportional to the top of the cylinder. The left side of the instrument is the flywheel, the right side is the crank timing gear, and the camshaft timing gear. This instrument is equipped with a light display device, and the power supply voltage is 1.5 volts. When the receiver is running, the lights will flash in sequence, which can more intuitively explain the actions of intake, exhaust, and ignition.
