Automotive Engine Performance Flashcard

Front

What is the function of the throttle body in an automotive engine?

Back

The throttle body regulates the amount of air entering the engine.

Front

What is the role of the exhaust system in an automotive engine?

Back

The exhaust system removes exhaust gases and reduces noise, while also optimizing the flow of exhaust gases to improve engine performance.

Front

What are common causes of engine misfire?

Back

Common causes of engine misfire include spark plug issues, fuel delivery problems, vacuum leaks, and mechanical issues.

Front

How does engine misfire affect engine performance?

Back

Engine misfire can lead to reduced power, rough idling, and increased fuel consumption.

Front

What is engine tuning?

Back

Engine tuning can improve engine performance by optimizing power output and efficiency through adjustments to fuel and air mixture, ignition timing, and other parameters.

Front

What is the difference between naturally aspirated and turbocharged engines?

Back

Turbocharged engines produce more power and torque compared to naturally aspirated engines.

Front

What is the impact of a dirty air filter on engine performance?

Back

A dirty air filter restricts airflow to the engine, leading to reduced power and efficiency.

Front

What is the purpose of the fuel injector in an automotive engine?

Back

The fuel injector delivers the correct amount of fuel into the engine's combustion chamber.

Front

How does a catalytic converter affect engine emissions?

Back

A catalytic converter reduces harmful emissions by converting toxic gases into less harmful substances before they exit the exhaust.

Front

What is the significance of engine compression ratio?

Back

The engine compression ratio affects power output, efficiency, and the type of fuel that can be used.
