What is the main difference between an Otto-cycle and Diesel-cycle engine?
Otto engines use spark ignition, while diesel engines ignite fuel through the heat created by high compression.
How does electronic fuel injection improve engine operation?
It uses sensors and a control unit to meter fuel precisely for better starting, performance, fuel economy, and emissions.
What does a turbocharger do in a car engine?
A turbocharger uses exhaust energy to force more air into the engine, allowing it to produce more power.
