BJ492 / 4RB / DK4A

The engines Beijing Automotive built for the Chinese Pajero and the Beijing Jeep Cherokee — BJ492, the 4RB petrol fours and the DK4A diesel.

⚑ These cars look like Mitsubishis and Jeeps and are not. Beijing Automotive built both under long-running joint ventures with its own engines beside the licensed ones, and a Chinese-market Pajero of this period frequently carries an engine the Japanese car never had. Ordering parts from a Mitsubishi or Jeep catalogue is the standing mistake.

The BJ492 traces back to a 1960s design and stayed in production for decades — it is simple, mechanical, and still supported in its home market long after the vehicles left every other one.

Establish which engine is actually fitted before anything else. The badge, the model name and the chassis plate will not tell you; the engine's own casting number will.

Documentation outside China is essentially nonexistent, and that is the practical constraint rather than anything about the engineering.
