How many cylinders can an engine have according to the classifications mentioned?

• Four, five, six, eight, 12

• Two, three, seven, nine

• One, three, five, seven

• Ten, eleven, thirteen, fourteen

What is the arrangement of cylinders in an engine?

• V-type, inline

• Overhead cam, pushrod

• Air or liquid

• Gasoline, diesel

What is the purpose of the power stroke in a four-stroke engine?

• To move the piston and produce power

• To compress the air-fuel mixture

• To release exhaust gases

• To cool the engine

What happens during the power stroke in an engine?

• The piston moves upward, pushing exhaust gases out.

• The piston is at TDC and combustion pushes it down.

• The intake valve opens to allow air-fuel mixture in.

• The crankshaft rotates twice.

How many times does the power stroke occur per second at 4,000 RPM?

• 5 times

• 10 times

• Over 30 times

• 20 times

What is the main purpose of the exhaust stroke?

• To ignite the air-fuel mixture

• To remove spent gases from the cylinder

• To compress the air-fuel mixture

• To lubricate the engine

What is a common feature of gasoline-powered engines?

• They are all two-stroke engines.

• They are all electric engines.

• They are four-stroke, reciprocating piston engines.

• They have no exhaust system.

What happens when the piston in a two-stroke engine moves downward?

• The intake and exhaust ports are closed

• The intake and exhaust ports are covered

• The intake and exhaust ports are both uncovered

• The reed valve opens

How do diesel engines ignite fuel?

• Using a spark

• Using compression ignition

• Using a reed valve

• Using a supercharger
