Design

The designs optimize fuel injection and intake porting to improve combustion performance, particularly low-temperature combustion stability though lean air-fuel rationing.

This ensures that we satisfy the world’s strictest exhaust emission standards while providing the smooth, quiet and efficient power for which Hyundai SeasAll is becoming known.
