Q

What is the average piston speed of a 4 cycle diesel engine with a 12 inch stroke, operating at 900 RPM?

🔍 Key Concepts

• Formula for average piston speed in a 4-stroke engine • Relationship between stroke length, RPM, and distance traveled per minute • Unit conversion from inches to feet

💭 Think About

• First, determine how many inches the piston travels in one complete crankshaft revolution in a 4-stroke engine. • Then figure out how many revolutions occur per minute at 900 RPM, and multiply to get total distance per minute. • Convert the total distance per minute from inches per minute to feet per minute and compare with the options.

✅ Before You Answer

• Remember that in one crankshaft revolution the piston travels from TDC to BDC or BDC to TDC, not both. • In a 4-stroke engine, think carefully about how many strokes occur per two crankshaft revolutions versus per one revolution. • Be sure to convert 12 inches of stroke into feet correctly before matching your final value to the multiple-choice answers.
