DEVELOPMENT OF 2-STROKE ENGINE BRAKE USING THERMODYNAMIC AND MECHANICAL SIMULATION MODELS
Original language description
The simulation work aims at advanced valve lift and timing for a heavy duty Diesel application that enables advanced 2-stroke engine brake mode with superior performance. This system has not been used in series production yet and is being developed by HD engine manufacturers. The paper describes the principle of the 2- stroke engine brake and the meaning of used valve lifts. 1-D thermodynamic simulation coupled with advanced optimization tool allows finding feasible valve lift profiles enabling high negative brake torque. The optimized profiles must comply with restrictive constraints related to mechanical and thermal limits of the engine and constraints of the specific type of the proposed advanced valvetrain design. A mechanical simulation model is also used to provide a dynamic analysis of the valvetrain system and cam design.
