The quality of GAC Trumpchi's engines is still good. It is independently developed and has good performance.
This 4B20J1 engine uses in-cylinder direct injection technology, with an injection pressure of 350bar, which is much higher than the 200bar of conventional in-cylinder direct injection. The higher the injection pressure, the better the atomization effect of gasoline, which greatly improves the combustion efficiency of gasoline, achieving the effects of saving fuel and improving power. The technology of in-cylinder direct injection GCCS high tumble combustion chamber is a patent of GAC Group. Through the unique design of the air inlet and piston top, the air entering the cylinder is fully mixed with the gasoline to increase the combustion speed. This is the core key to the 4B20J1 engine being both fuel-efficient and powerful.
