Dongfeng JAC 3.8L CY4102BZLQ Engine

The 3.8L CY4102BZLQ engine (manufactured by Dongfeng Chaochai and extensively cross-listed with JAC commercial vehicles in aftermarket catalogs) is a legendary and virtually indestructible inline-4 turbo-diesel engine engineered for extreme heavy-duty commercial performance and massive load-bearing capacity. Developed as the absolute backbone of China's light and medium-duty truck industry, this robust powertrain features a highly reliable Overhead Valve (OHV) 8-valve configuration, a gear-driven camshaft, and a proven Direct Injection system. Combined with a heavy-duty Turbocharger and Intercooler (denoted by the "ZLQ" designation), it ensures massive low-end torque delivery and consistent efficiency under severe overloading conditions. With a displacement of 3,856 cc, it produces a highly capable output ranging from approximately 110 to 120 hp, and up to 350 Nm of torque. This engine is highly compatible with iconic commercial models such as the Dongfeng Duolika and the JAC Junling/Kangling series, providing dependable and economical performance for urban logistics, construction transport, and regional freight hauling. Designed to maximize fleet uptime in the harshest environments, the CY4102BZLQ engine offers an all-cast-iron construction, extreme mechanical simplicity, and a highly accessible global parts ecosystem. Its mature engineering reinforces its reputation as the ultimate "workhorse" diesel powertrain suitable for demanding global transport conditions, particularly in emerging markets.
