Motorcycle piston force

The piston is one of the most critical components in the engine. The role of the piston is to withstand gas pressure, and through the piston pin to the connecting rod drive the crankshaft rotation, the top of the piston and the ring, cylinder head combustion chamber, so the piston in high temperature, high pressure, high speed, poor lubrication conditions.

Gasoline piston is mainly made of aluminum alloy, the piston shape is complex, the need for processing equipment and more production processes more demanding, bearing capacity, high temperature resistance, small expansion coefficient (piston skirt shape is oval, heated large size Slightly smaller), corrosion-resistant and so on.

Motorcycle pistons are mainly divided into four-stroke and two-stroke, the difference between the shape of them mainly in the ring groove and a little two-stroke piston surface window. Parts are often overlooked and do not know what they do, but as a professional motorcycle rider, it is important to understand the function and function of each part to better focus on their "health" issues and to make them more " treatment". Safety is not your car driving, safe driving on it, the mount is not sick is the most important.

Motorcycle piston force: the pressure in the piston ring gas pressure, the ring's own elastic force, ring reciprocating inertia, ring and cylinder and ring groove friction, as shown. As a result of these forces, the ring will generate axial, radial and rotational movements. In addition, the piston ring due to its movement characteristics, along with the irregular movement, inevitably occur due to axial irregular motion caused by the suspension and axial vibration, radial irregular motion and vibration, torsional movement and so on. These irregular movements often prevent the piston ring from functioning. When designing a piston ring, give full play to beneficial sports, control the negative side.

Motorcycle piston is thermal conductivity: the heat generated by combustion, passed through the piston ring to the cylinder wall, it can play the role of cooling the piston. Through the piston ring to the cylinder wall heat, generally can withstand 30 ~ 40% of the top of the piston to withstand heat.
