Abstract

The cylinder head is provided with recesses to receive a reinforcement unit. The space between the recesses has vertical air cooling fins. The cylinder head sides are provided with air cooling fins laying parallel to the two inlet valve seats and valve guide bores are provided whose centres are symmetrical to a plane vertical to a longitudinal axis. The centre distances are greater than that of the inlet valve centres owing to bigger valves being employes for the exhaust. The vertical ribs are rounded off to allow an injector to be fitted.
