The Chery 372 engine is a classic small displacement power unit independently developed by Chery Automobile in China, featuring an inline three cylinder, 1.0-liter naturally aspirated design. This engine is installed in micro cars such as Chery QQ3 and was once known for its high efficiency and energy saving. It has a maximum power of 50kW/6000rpm and a peak torque of 93N · m/3500-4000rpm. By optimizing the combustion chamber structure and lightweight aluminum alloy cylinder body, a low fuel consumption performance of 5.3L/100km has been achieved, which meets the National IV emission standard. As an early positive research and development achievement of Chery, the 372 engine demonstrates the domestic brand’s technological breakthrough in the powertrain field. Its compact layout and reliable durability help Chery models succeed in the entry-level market, laying the foundation for subsequent engine technology upgrades.
