Geely GeTec engine series with high efficiency and green energy saving, derived from G=Green=Geely, e=Efficient=Engine, Tec=Technology, is developed by Geely based on the technical concepts of high efficiency , energy saving, green and environmental protection, continuous innovation and continuous breakthroughs. A series of advanced motor products with completely independent intellectual property rights.
The engine of the γ platform is a series of 4-cylinder gasoline engines with golden displacement. There are currently 1.5L and 1.8L displacement models, both of which are currently the best-selling displacement models on the market. The γ engine uses advanced technologies such as an all-aluminum alloy cylinder block, plastic intake manifold, DCVVT, gear timing drive and electronic throttle to deliver excellent power while holding economic accountie fuel. In addition, γ series engines also have a wide range of alternative fuel engines, such as CNG compressed natural gas engines, ethanol engines, methanol engines, etc., to meet the different market needs. The γ engine is another core engine platform from Geely, supporting Geely A-B class models, such as Emgrand EC7, Vision, British SC7 and the upcoming Emgrand EX7 SUV model.

Generally, cars use four-stroke engines. The order of the four strokes is the intake stroke, that is, when the piston. moves from bottom dead center to top dead center, the mixed gas of air, fuel and lubricating oil enters the crankcase; after completing the compression stroke, the spark plug ignites and starts the power stroke, and the piston moves from top dead center to top dead center. bottom dead center, quickly When reaching the bottom dead center, the exhaust port opens first and the high temperature burnt gas is discharged. However, the scanning port opens almost at the same time. Gas mixed in the crankcase is forced into the crankcase. cylinder from the scavenging port by the descending piston, and the burnt gas is discharged from the exhaust port. The air port is then expelled to complete ventilation.
