Abstract

The invention provides an automobile exhaust pipe heat insulation system and an automobile with the same. The automobile exhaust pipe heat insulation system comprises a heat insulation piece, a rotating piece and a driving piece which are arranged in sequence. The heat insulation piece is fixedly connected with the rotating piece; and the rotating piece can rotate under the driving of the driving piece, so that the heat insulation piece rotates relative to the automobile exhaust pipe. The automobile exhaust pipe heat insulation system provided by the invention is simple in structure, the position of the heat insulation piece can be adjusted according to different heat released by an exhaust pipe, so that high-temperature heat insulation can be achieved, and waste heat utilization at low temperature can also be achieved.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas utilization, in particular to an automobile exhaust pipe heat insulation system and an automobile having the same. Background technique [0002] After the engine burns fuel, about 40% of the energy is dissipated in the form of exhaust waste heat, and the temperature of the exhaust pipe of a car can reach 400-500°C. Especially after the implementation of the National VI emission standards, turbocharging technology and particulate filters are widely used in automobiles, which makes the temperature of automobile exhaust higher. Turbocharging is a technology that uses the exhaust gas generated by the operation of the internal combustion engine to drive the air compressor, which can significantly increase the intake air volume of the engine, thereby improving the power and fuel economy of the engine. The ceramic filter in the system can effectively reduce the emission of particulate matter...
