Hyundai Beta engine

The Hyundai Beta engine is a family of inline four-cylinder petrol engines, ranging from 1.6 to 2.0 litres, that Hyundai built at its Ulsan plant in South Korea from the mid-1990s. Every version uses a dual overhead camshaft valvetrain in which the camshafts sit in the cylinder head and operate the valve tappets directly, and a distributorless ignition system managed by the powertrain control module. The first generation covered the G4GR 1.6 litre, G4GM 1.8 litre and G4GF 2.0 litre engines, which powered the second-generation Elantra and the Coupe, also sold as the Tiburon. The Beta II generation followed with the 1.8 litre G4GB and the 2.0 litre G4GC, the latter gaining continuously variable valve timing from 2003 and reaching the Elantra, Tucson and Trajet as well as several Kia models. An LPG version, the L4GC, was also offered.
