| 摘要 |
A liquid-cooled engine and method for its operation is described wherein the engine includes a cylinder head comprising at least one coolant jacket and exhaust manifold at least partially integrated therein. In one particular example, the exhaust pipes merge in stages within the cylinder head before merging into a common exhaust gas collector outside the cylinder head. Inclusion of a coolant system according to the present disclosure allows the thermal load of the cylinder head to be controlled, which thereby allows cooling to be achieved in a targeted manner inside the cylinder head by means of liquid cooling and forced convection.
