If a written answer is required, it should be complete, concise, neat and grammatical. If your answer involves calculations, show all formulas, work and units and draw a box around your final answer. A. Difference in volume in the combustion chamber as the piston moves from bottom to 1. Match the following terms with th top 1. _____ Carburetion B. material used to produce heat or power by burning C. substance used to reduce friction and heat D. space inside an engine block commonly referred to as a cylinder E. machine that converts energy into mechanical motion (rotation motion to linear motion) F. cylindrical shaped engine part that is inside the combustion chamber G. instance of burning H. supplying an air/fuel mixture to the combustion chamber I. commonly measured as cubic centimeters, cubic inches, and liters J. pressure that is created in the combustion 10. _____ Piston chamber as the piston reduces the amount of volume within the combustion chamber

2. A. Determine the engine displacement of a 3-cylinder engine that has a stroke of 2.375 inches and a bore diameter of 75 mm. (1 inch = 25.4 mm).

B. What is the compression ratio for this engine if the total clearance volume is equal to 3 in3?

C. Diesel engines have a compression ratio between 14:1 to 25:1, whereas a gasoline engine has a compression ratio downward of 6:1 to 12:1. Based off of this, what fuel do you think is being run in this engine?

3. Determine the follow micrometer readings....
