EA888 engine specifications and design
The EA888 engine has several variations, each designed with different specifications. In general, however, the engine is known for its:
- Lightweight construction – It is made of cast iron, which is lighter than the previous cast-iron block.
- Turbocharging – Its single-scroll turbocharger increases power output and throttle response.
- Direct injection – This delivers fuel directly into the combustion chamber for improved fuel efficiency and reduced emissions.
- Dual overhead camshaft – A DOHC valvetrain improves engine breathing for greater control over the engine’s valve lift and timing.
- Electric wastegate – This improves the turbocharger response, reducing turbo lag.
- Engine management system – A Bosch MED17 engine management system controls the engine’s ignition timing and fuel injection to optimize efficiency and performance.
