For this reason, a high percentage of the air in the cylinder is forced into the turbulence chamber during the compression event. The opening to the turbulence chamber becomes smaller as the piston reaches TDC, thereby increasing the velocity of the air. Velocity plus deflection of the air as it enters the auxiliary chamber creates considerable turbulence. This ensures a thorough mixing of the air and fuel. The greater part of combustion takes place within the turbulence chamber and is completed as the burning gases expand and force the piston down in the power event.
Energy cells differ in design and location.
In most engines, the cells are located in the cylinder heads. One type of energy cell that is located in the cylinder head is a divided chamber and turbulence chamber. The Lanova cell is the divided chamber type. Refer to figure 9-3 as we discuss how the energy cell system works. Study the construction and operation of a typical system, the Lanova design, shown in figure 9-3.
