Abstract Transition from conventional combustion to low temperature combustion was studied by using closed loop combustion control system. The test results reveal that the cyclebased closed loop control system can follow c （crank angle corresponding to 50% of total heat release） step input and restrain system disturbances such as speed, load, rail pressure and exhaust gas recirculation (EGR). During the transition process, fuel injection timing can be adjusted in time to keep the combustion phase at the set point, in other words, combustion stability is ensured.
