Xxx internal combustion 4

When the fuel is injected directly against the cylinder head face, and the air layers swirl in a smooth substantially circular path about the bore axis, a secondary air motion becomes noticeable. I illustrates a longitudinal section through the upper portion of ti piston in a cylinder and also shows a fuel jet in the arrangement according to the present invention. The core member 29 is integral and is located and extends over both cylinders, being arranged with its axis in the axial plane common to the two cylinders. That is, only a smattering of fuel particles wet the cylinder head face or combustion chamber walls. The amount of axial displacement is prefercirculation of water or other cooling medium,.

In operation, the opening and closingmovements of the two intake valves 80 and 84 are scheduled so that, initially, during the first part of the intake stroke, approximately three-quarters of the total air charge enters through the primary valve with an axial swirling motion. If this be reguired the oil may be introduced through a not leading to the cylindrical chamber out of register with the control ports but in register, if desired, with oil ports in the valve sleeve.
