Champion RC78PYP natural gasoline Generator Spark plug for Denso GK3-1A , GK3-5A

What is spark plug:

A spark plug is a device used in an internal combustion engine — that is, an engine that derives its power via exploding gases inside a combustion chamber — to ignite the air-fuel mixture.

Cars typically have four-stroke gasoline engines, which means there are four strokes, or movements, to the moving parts inside the engine per rotation. Inside each cylinder is a piston, which moves up and down within the cylinder to compress the gas for combustion, and pushes the exhaust gases out after combustion. The piston is operated by an arm that attaches to the crankshaft, a shaft that extends through the bottom of the engine. The piston goes up and down twice during each rotation, hence the four strokes -- up, down, up, down.

The spark plug is positioned at the top of the cylinder, where the air-fuel ratio is compressed. The tip of the plug sits inside the engine, recessed into the side of the cylinder wall. The other end remains outside the engine and is attached to a wire that is also attached to the distributor
