The embodiment of the invention provides a capsule type engine oil pulse buffer and an automobile. The capsule type engine oil pulse buffer comprises an outer cylinder formed by welding of a thin-wallsteel tube and an inner cylinder made of rubber; the inner cylinder is arranged in the outer cylinder and fixedly connected with the outer cylinder, and a cavity in the inner cylinder is an engine oil cavity allowing circulating of engine oil; an engine oil inlet and an engine oil outlet are correspondingly formed in the two ends of the outer cylinder and communicate with the engine oil cavity; and six protrusions towards the inner side are arranged on the inner wall of the outer cylinder and serve as a supporting structure to support the outer wall of the inner cylinder, so that a gap is reserved between the outer wall of the inner cylinder and the inner wall of the outer cylinder. By using the capsule type engine oil pulse buffer, the pulse effect of the engine oil can be effectively reduced, and the NVH problem caused by the pulse effect is eliminated; the capsule type engine oil pulse buffer is small and ingenious in size, and rearranging the pipeline trend for the capsule type engine oil pulse buffer is not required; and a main body steel structure is high in reliability and has a certain mass so that the effect of reducing the amplitude of an oil tube can be achieved. The capsule type engine oil pulse buffer is mounted in an oil circuit of the engine oil.
