Abstract (en)
The lubrication of seats is possible thanks to the incorporation of an internal pressurized oil circuit that is driven through a pump circulating an oil flow rate towards the camshaft and rocker arm shaft seats through various pipes. These seats are located in a cylinder head, whereas the rocker arm shaft seats are located in an upper support sit on an upper surface of the cylinder head, while also holding a part of the camshaft in correspondence with its seats. The improvements are characterized in that the cylinder head (1) includes at least two transverse bores (2-3) that are part of the pressurized oil circuit, and from which upstream pipes (4-5) are extended flowing into the camshaft (8) and rocker arm shaft (9) seats (6 -7).
