1. In an internal combustion engine, fuel is burned the engine.
2. In the
stroke of the four-stroke cycle, the piston rises, compressing the air-and-
fuel mixture trapped in the combustion chamber.
3. In an engine, the stroke is the distance the piston
4. When a piston is at its lowest position in the cylinder, it's said to be at
5. During the
stage of engine operation, gases are released from the cylinder.
6. A four-stroke engine will contain at least two mechanical valves called the
valve
and the
valve
7. In the
stroke of the four-stroke cycle, air mixed with fuel is drawn into the
cylinder.
8. The total engine
I is stated as the volume of the space swept through by all the
pistons.
9.
A two-stroke engine completes all four stages of engine operation in four piston
strokes
10. During the
stroke of the four-stroke cycle, the mixture of air and fuel is ignited,
and the contained explosion of the fuel presses the piston back down in the cylinder.
11. The top of a cylinder is sealed by the cylinder
12. The
is the ratio of the total cylinder volume to the clearance volume.
