Engine and automobile

The utility model relates to an engine and an automobile. The engine comprises a cylinder body, an oil-gas separator and an intake manifold, a containing cavity is formed in the cylinder body, and the containing cavity is communicated with a crankcase of the cylinder body; the oil-gas separator is at least partially arranged in the accommodating cavity, and a gas inlet of the oil-gas separator is communicated with the accommodating cavity; a gas inlet channel of the gas inlet manifold is used for communicating a gas outlet of the oil-gas separator with a combustion chamber of the engine. Compared with the arrangement mode that the oil-gas separator is arranged on the cylinder cover cap in the prior art, the scheme can shorten the distance between the oil-gas separator and the crankcase, so that the blow-by gas can reach the oil-gas separator without flowing through the cylinder cover and the cylinder cover cap, the flowing path of the blow-by gas can be effectively shortened, and the oil-gas separation effici
