Abstract (en)
[origin: EP0474217A2] The present invention relates to a self-operating mechanism for a 4-cycle internal combustion engine comprising more than two intake valves and a plurality of exhaust valves, specifically to a 5-valve engine. In order to provide sufficient space for the cooling jacket on the exhaust side of the cylinder head and/or increasing the valve lift of the exhaust valves without increasing the total height of the engine, the valve spring retainers of the exhaust valves together with the upper ends of the associated exhaust valve springs are accomodated inside the exhaust valve lifters, respectively, while the valve spring retainers of the intake valves are disposed adjacent to a lower end of the associated intake valve lifters. <IMAGE>
