Briggs & Stratton 841837 Engine Standard Piston Assembly

The Briggs & Stratton 841837 Engine Standard Piston Assembly is a moving internal part of the motor that converts the combustion power to the connecting rod during operation. It is carried in the cylinder where it compresses the air-fuel mixture before it is ignited and the gases after combustion to drive the cylinder. The assembly is mounted in the cylinder of the engine and operates in conjunction with the piston rings, the wrist pin and the attached rod to ensure regulated movement. The proper piston movement ensures even power distribution, combustion and engine stability under standard operating conditions.
