What is FSI ENGINES explain?

FSI (Fuel Stratified Injection) engines are a type of gasoline engine technology developed by Volkswagen that optimizes fuel efficiency and performance. In an FSI engine, fuel is injected directly into the combustion chamber rather than mixing with air in the intake manifold, allowing for a more precise fuel-air mixture. This stratified charge approach enables better combustion at lower engine loads, improving fuel economy while maintaining power output. FSI technology is often used in conjunction with turbocharging to enhance engine performance and responsiveness.
