The GM LTG is a 2.0-liter turbocharged inline-four gasoline engine from the Ecotec family, introduced in 2013 and produced through approximately 2023. It features an all-aluminum
block and head, DOHC 16-valve configuration with dual variable valve timing, direct injection (SIDI), and a dual-scroll turbocharger. Power output typically ranges from 250 to 275 hp
with 260–295 lb-ft of torque, depending on the application.
The LTG uses a two-stage variable-displacement oil pump. This advanced design adjusts oil flow according to engine load, reducing parasitic losses at low load for improved fuel
efficiency while providing full flow and pressure under high-load and high-boost conditions. The pump works in conjunction with piston cooling jets and an oil cooler to maintain
optimal lubrication and temperature control. In many applications the oil pump is integrated with a modular balance shaft system located in the oil pan area and is driven by the crankshaft.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
