Briggs and Stratton Week 2 Pretest

Which component in the ignition system is responsible for generating the high voltage needed to create a spark at the spark plug?

• Distributor

• Ignition Coil

• Spark Plug

• Battery

What is the primary function of a carburetor in a four-stroke engine?

• To cool the engine

• To mix air and fuel in the correct ratio

• To lubricate engine parts

• To increase engine speed

Identify the type of ignition system that uses a computer to control the timing of the spark.

• Magneto Ignition System

• Distributor Ignition System

• Electronic Ignition System

• Capacitor Discharge Ignition System

Explain how the governor system in a four-stroke engine maintains a constant speed.

• By adjusting the throttle position based on engine load

• By changing the air-fuel mixture

• By altering the ignition timing

• By increasing the engine temperature

Which technique is used to adjust the air-fuel mixture in a carburetor for optimal engine performance?

• Changing the spark plug gap

• Adjusting the idle screw

• Replacing the air filter

• Modifying the exhaust system

Describe the process of adjusting ignition timing in a four-stroke engine.

• By changing the fuel type

• By rotating the distributor

• By adjusting the carburetor jets

• By replacing the spark plug

Analyze the impact of an incorrect air-fuel mixture on engine performance and emissions.

• It improves fuel efficiency

• It reduces engine power and increases emissions

• It has no effect on the engine

• It increases engine power and reduces emissions

Evaluate the advantages of using an electronic ignition system over a traditional distributor ignition system.

• Lower cost and complexity

• Improved fuel efficiency and reduced emissions

• Easier maintenance and repair

• Increased engine noise

How does the governor system respond to an increase in engine load to maintain speed?

• It decreases the fuel supply

• It increases the throttle opening

• It reduces the ignition timing

• It closes the exhaust valve

Propose a method to improve the accuracy of ignition timing adjustments in a high-performance engine.

• Use a timing light and adjust based on engine RPM

• Change the engine oil more frequently

• Install a larger carburetor

• Use a higher octane fuel
