1. 5 parts

2. 1. Burned gases removed by the motion of the a piston. 2. The movement of a piston from top to bottom or from bottom to top. 3. A sliding cylinder fitting within a cylindrical vessel that receives the force of combusting fuel. 4. The engine process in which burning fuels expands rapidly but evenly to drive the piston down. 5. Movement of a piston which expels burned gases from a cylinder. A. Exhaust stroke B. Power Stroke C. Piston D. Stroke E. Exhaust

3. 6. Doing the tasks that keep a machine in good condition. 7. Engine process of taking fuel and air into the combustion chamber 8. Movement of an engine piston to squeeze or compress the air-fuel mixture. 9. A spark igniting an air-fuel mixture 10. Turning force of the flywheel and other moving parts that carries an engine through nonpower strokes. 11. To replace a faulty part or make it work correctly A. Repair B. Momentum C. Intake stroke D. Ignition E. Compressio n Stroke F. Maintenanc e

4. 12. Determining what causes a malfunction in a machine or process. 13. All the events that take place as an engine takes in air and fuel, compresses the air-fuel mixture, burns the fuel, and expels the burned gases. 14. Device that burns fuel inside a cylinder to create a force that drives a piston. 15. A shaft with an offset projection that converts circular motion to reciprocal motion, or vice versa. A. Crankshaft B. Troubleshootin g C. Cycle D. Internal Combustion Engine

5. 16. Provides fuel and air to the engine in appropriate portions and volume. 17. Produces electricity by magnetism 18. The rotating part of a motor. 19. Seal between the head and the cylinder block 20. Complete the seal between the piston and the cylinder wall. 21. Stores and releases current to boost current in the Primary circuit. A. Head gasket B. Armature C. Condensor D. Magneto E. Carburetor F. Rings
