Technologies
Technologies that make the combustion process efficient
- Direct fuel injection - Injects fuel directly into combustion chamber metering fuel more precisely.
- Variable valve timing - Varies intake and/or exhaust valve opening and closing times demanded by the engine.
- Turbochargers - Increases cylinder pressure, more air larger explosion. More power from smaller engines.
- Cylinder deactivation - Literally deactivates a set of cylinders stopping combustion.
