Small Engines Pre Test

What is the purpose of using micrometers in small engine maintenance?

• To measure the engine's horsepower

• To check the engine's oil level

• To precisely measure small engine components

• To adjust the engine's timing

Difference between 4 and 2 stroke engines

• 4-stroke engines have intake, compression, power, and exhaust strokes while 2-stroke engines have intake/compression and power/exhaust strokes.

• 2-stroke engines are more fuel-efficient than 4-stroke engines.

• 4-stroke engines require a fuel-oil mixture for operation.

• Both engines have the same number of strokes.

Internal combustion engine:

• Converts chemical energy into mechanical energy

• Runs on electricity alone

• Does not require any fuel

• Only operates externally

What is the purpose of a clutch in a small engine vehicle?

• To control the engine's speed

• To engage and disengage power transmission

• To adjust the engine's fuel intake

• To regulate the engine's cooling system

How does the cooling system in an engine help prevent overheating?

• By increasing fuel consumption

• By regulating the engine's oil level

• By dissipating excess heat

• By reducing the engine's power output

4-stroke engines require how many rotations of the crankshaft to complete a full cycle?

• 1

• 2

• 3

• 4

What information is typically included in a work order for small engine maintenance?

• Customer's favorite color

• Detailed list of required parts

• Work to be preformed

• Employee's lunch schedule

Which type of engine is generally lighter and simpler in design - 2-stroke or 4-stroke?

• 2 stroke

• 4 stroke

Cooling System:

• Helps to maintain the engine at a constant temperature.

• Is not essential for engine operation.

• Only cools the exterior of the engine.

• Is not related to engine performance.

What does the acronym "CAN" stand for in the CAN bus system used in vehicles?

• Car Audio Network

• Central Access Network

• Controller Area Network

• Computerized Automotive Network
