Numerical Simulation of a Controlled Trajectory Rapid Compression Machine

In conventional internal combustion engines, due to the unstable and “unpredictable” turbulent combustion phenomena, heavy crank shafts are used to ensure stable and robust operations by their large inertia. Such heavy crank shafts limit the flexibility of the piston motion such as compression ratio, which is a bottleneck for the improvement in fuel economy. In addition, the piston trajectory is fixed for all operation conditions (i.e., speed...
