Gamvdout Gasoline engine model Internal Combustion Engine Model 4 Stroke Internal Combustion Engine Model Kit for Middle School Physics Course Experiment Teaching.

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