increase additional diesel fuel, and combined with O2, the combined gas will be burned completely and enlarge cylinder volume and displacement.
2. to make up powerless at high sea level
When sea level is high, relatively low content of oxygen in the air, the oxygen content in the cylinder is relatively smaller,it can provide more pressurized air into the cylinder so as to increase the oxygen content, the power will return to normal condition at the altitude.
3. Turbocharger can make fuel burn more fully, thereby reducing emissions, reduce pollution and protect the environment
