Audited Supplier Gasoline engine model for school
Product Introduction
The front of the gasoline engine model for school is a section cut along the longitudinal axis of the cylinder, the cylindrical cavity in the middle is the cylinder, and the light-colored parts on both sides of the cylinder represent the section of the cooling water jacket. The piston moves up and down in the cylinder. The fingerprints on the piston indicate the piston ring and the oil ring. The square cavity below the cylinder is the crankcase. The rear one is a camshaft with two cams in different positions, which push the push rod to move up and down in turn, and control the opening and closing of the intake valve and exhaust valve at the top of the cylinder through the rocker arm. At the top of the cylinder is the spark plug.
The left side of the instrument is the flywheel, the right side has the crank wheel, and the camshaft timing gear.
The compression ratio of gasoline engines is generally 5-8, so when the piston rises to the top dead center, there is a certain gap at the top of the cylinder in proportion to the top.
This instrument is equipped with a light display device. The supply voltage is 1.5 volts. When the instrument is running, the lights will flash in sequence, which can more intuitively explain the actions of intake, exhaust and ignition.
There is a handle on the flywheel, which is only used to drive the flywheel to rotate during demonstration, and there is no thing.

Product feature and application
For the teaching demonstration of the heat engine part of the physics class in the middle school.
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.
Maintenance and precautions
This gasoline engine model for school is generally adjusted, and the actions of all parts are coordinated. There is no need to adjust it when using it. However, after a long time, there may be obstacles in some places. It is common that the points of the power distribution circuit are in poor contact, and the small electric beads will not Lights up, each contact needs to be checked in turn.
The model should pay attention to keep the rotating parts clean and add lubricating oil. If the electric beads do not light up during use, you can check whether the electric beads are burned out, whether the joints are falling off, and whether the printed circuit board (behind the flywheel) is oxidized, and then repair it.
