History of JAC Engines
JAC engine production began in the early 2000s. The first power units were used in JAC J3 passenger cars and HFC series commercial trucks. The HFC4DA1-1C and HFC4DE1-2D engines provided sufficient power and stable performance for cargo transportation and daily operation.
During the period from 2008 to 2015, JAC modernized its engines by introducing the HFC4DA1-2B and HFC4DE1-3B models, which featured improved fuel efficiency, higher torque, and reduced emissions. At the same time, cooling systems, fuel injection, and electronic control systems were further developed.
Modern JAC engines (HFC4DB1-2D, HFC4DE1-3D) comply with Euro-4 and Euro-5 standards and are used in trucks, commercial vans, and passenger vehicles. They provide high reliability, durability, and the ability to operate under intensive conditions on all types of roads.
