The World Gasoline Engine is a family of straight-4 piston engines, based on the Global Engine Alliance design.
Three engines have been produced: a 1.8 L, a 2.0 L, and a 2.4 L. The initial design of the engine block and cylinder head was handled by Hyundai as part of the Global Engine Alliance. The engines feature an aluminum engine block with siamesed cast iron cylinder liners (which do not allow coolant to flow between adjacent liners). By using cylinder liners, the engine's bore can be altered, therefore the displacement as well, just by adding a different set of cylinder liners. The engine also features an aluminum cylinder head with double overhead camshafts and variable valve timing.
The 1.8L is a dual overhead cam (DOHC) inline 4-cylinder gasoline engine capable of and of torque. The engine has displacement of with a bore of and a stroke of . The compression ratio is 10.5:1.
The 1.8L DOHC inline 4-cylinder engine served as the standard engine in the Dodge Caliber SE and SXT trim for the 2007âÂÂ2009 model years.
Applications:
The 2.0L DOHC inline four-cylinder gasoline engine is capable of and produces of torque. The engine has a displacement of with a bore and a stroke of . The compression ratio of the engine is 10.5:1. The 2.0 L engine was offered by Dodge in the Dodge Caliber. Outside North America, the 2.0 was the base engine for the 2007 Chrysler Sebring and 2008 Dodge Avenger.
Applications:
The 2.4 L, engine was used by Dodge in the R/T trim line of the Caliber. The dual overhead cam (DOHC) inline four-cylinder engine had of displacement with a bore and a stroke of . A turbocharged variant of this engine was used in the high-performance SRT-4 version of the Caliber.
Applications:
The Tigershark engine family is the name for the next generation of World Gasoline Engines, with work starting on them shortly after Fiat's acquisition of Chrysler. The major differences compared to the first generation are the updated valvetrain and intakes.
The 2.0 L Tigershark DOHC inline 4-cylinder gasoline engine has dual-variable valve timing and produces and of torque. It utilizes a bore and stroke of and a 10.2:1 compression ratio.
Applications:
The 2.4 L Tigershark SOHC inline 4-cylinder gasoline engine uses MultiAir 2 variable valve timing and variable valve lift technology and produces and of torque. Only Multi-Air heads feature electro-hydraulic variable valve timing and lift, although only on the intake side. The system is based on FIAT technology. It utilizes a bore and stroke of and a 10.0:1 compression ratio.
