four stroke engine with valves for admission and discharge two times more extensive than the four valves; punterie with one trigger point and two bearings reggispinta equipped with bumps that imare the law of up.

摘要

the new induction has light discharge is on the walls of the cylinder at the top, in the area where the bands can arrive.the valve of the load form unusual "donut" to obtain the maximum area of passage.the drain is required that the valve has a form similar to the crack of discharge, which is circumferential, similarly to the cylinder.since the opening to occlude develops around the upper part of the cylinder.the command show of both valves is transferred to a destruction particularly consists of one drop of recall for both the valves and two bearings reggispinta.equipped with speed bumps in the side adjacent to punterie roller, which impose the law of up. such architecture leaves wide freedom for the design of the combustion chamber.
