The engine was first introduced in 1996 Opel Corsa as a 3-cylinder version.
New, updated version of the engine, introduced in 2003. Features TwinPort technology - twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy.
For model year 2011, the Ecotec Twinport 1.2 and 1.4 engines have been updated with double cam phasing.
Ecotec TwinPort engines are used in:
The EcoFlex engine is a version of the TwinPort tuned to provide better fuel economy and lower emissions. The 1.4 L engine was introduced in 2008 and 1.0 L engine in 2010.
The EcoFlex engine is used in:
Opel and US-market Chevrolet versions of the Delta II platform compact cars use a turbocharged version of the 1.4 L engine with of variable valve timing; in the future, an optional gasoline direct injection system will be introduced.[1][2] This small turbocharged engine will deliver the performance of much larger naturally aspirated engines while maintaining fuel efficiency of a small engine. EPA estimated highway fuel economy is 42 mpg. [3] Opel versions feature Start&Stop system from 2011; a lower-power 120 ps version has been introduced as well.
The engine is used in:
The direct injection version of 1.4 L VVT Turbo engine will be able to operate in ignition-less HCCI (Homogeneous Charge Compression Ignition) mode [4][5] when equipped with two-step adjustable valve lift with variable cam phasing and advanced ECU with cylinder pressure sensors. 6.8–8 km/litre (16-19 mpg) in the city(over 800 km). 9–12 km/litre (21-28 mpg) on the highway (over 800 km) [in which vehicle?].
