Abstract

The invention relates to an internal combustion engine with at least a cylinder, the engine comprises: at least one cylinder cover, and a liquid cooling structure, the liquid cooling structure is provided with at least two coolant jackets (2, 8) integrated in the cylinder cover, wherein each cylinder is provided with at least one air outlet used for discharging exhaust at an outlet side, and at least an air inlet used for supplying fresh air at the inlet side. The invention aims at providing the internal combustion engine in the above type, and optimization is obtained in two aspects of cooling and wearing. In order to realize the purpose, the internal combustion engine is characterized in that, in the cylinder cover, at least a coolant jacket (2) is disposed at the outlet side and at least a coolant jacket (8) is disposed at the inlet side, wherein at least two coolant jackets (2, 8) are spaced part and belong to different independent coolant circuits.

Description

technical field [0001] The invention relates to an internal combustion engine with at least one cylinder, comprising: at least one cylinder head, and a liquid cooling structure with at least two cooling jackets integrated in the cylinder head, each cylinder having at least one gas outlet on the outlet side for It is used for discharging exhaust gas and has an air inlet on the inlet side for supplying fresh air. Background technique [0002] An internal combustion engine of the above-mentioned type is used as drive for a motor vehicle. In the context of the present invention, the term "internal combustion engine" includes diesel engines and spark ignition engines, as well as mixed fuel internal combustion engines, ie internal combustion engines which operate with a mixed combustion process. [0003] The internal combustion engine has a cylinder head and a cylinder block, which are connected to one another at the assembly end side to form a single cylinder. [0004] Cylinder...
