Description
Technical Field

[0002] The exhaust system refers to the system that collects and discharges exhaust gas. It is mainly composed of exhaust manifold, exhaust pipe, three-way catalytic converter, resonator, muffler and other components. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe (exhaust tail pipe). The main functions of the automobile exhaust system are as follows: ① Lead the exhaust gas to the rear of the vehicle to prevent harmful gases from entering the cab. ② Improve the emission pollution of the engine and reduce the harm to the atmosphere. ③ Reduce the noise of the engine exhaust gas.
[0003] In order to increase the air intake of the engine, thereby increasing the power and torque of the engine and making the car more dynamic, some cars are equipped with exhaust gas turbochargers, which use the exhaust energy of the internal combustion engine to drive the exhaust gas turbocharger to achieve engine supercharging. The exhaust gas turbocharger (referred to as turbocharger) is mainly composed of two main components: turbine and compressor, as well as shafts and bearings, lubrication systems, cooling systems, seals, thermal insulation devices, etc. The high-temperature and high-speed exhaust gas discharged from the engine cylinder is supplied to the turbine of the turbocharger through the exhaust pipe, driving the turbine to rotate, and the turbine then drives the impeller of the compressor coaxial with it to rotate. The compressor compresses the inhaled air and supplies the air with increased pressure into the cylinder of the engine, thereby achieving the purpose of supercharging.
[0004] The temperature of the exhaust gas from the engine to the exhaust manifold is about 800℃-900℃, the temperature in the front exhaust pipe is about 600℃-700℃, the temperature entering the turbine housing of the turbocharger is about 600℃-650℃, the temperature in the muffler on the exhaust pipe drops to basically 200℃-300℃, and the temperature of the tail muffler is about 150℃.

In addition, the heat in the exhaust manifold and the turbocharger (if installed on the car) is also wasted. Utility Model Content

In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

The muffler 15 is an original part of the car, but the water generated inside it will be recycled into the water recovery tank 16, and then pumped into the water storage tank 1 by the water pump B17 for storage, so as to realize the reuse of water resources. Preferably, the capacity of the water recovery tank 16 is V 1 , the capacity of water in the water recovery tank 16 is A water level sensor B is installed at the bottom of the water recovery tank 16, and a water level sensor C is installed at the bottom of the water recovery tank 16. If the water level sensor B detects that the water level in the water recovery tank 16 is too high, the water pump B17 can increase the horsepower to pump water into the water storage tank 1 to discharge more water in the water recovery tank 16. If the water level sensor C detects that the water in the water recovery tank 16 is insufficient, the water pump B17 will stop working to allow the water recovery tank 16 to store water.
[0046] Furthermore, the engine exhaust heat recycling system also includes an air-conditioning condenser 22 branch, and the air-conditioning condenser 22 branch includes a tee 18, a one-way valve B19, a water pump C20, a water collecting tank 21 and an air-conditioning condenser 22. The return pipe 14 includes a pipe section A141 and a pipe section B142.

[0047] The steam generating device for vehicle of the utility model has double-layer design for double-layer exhaust pipe 3, double-layer exhaust manifold 6 and turbine housing 7, which absorbs the heat of engine exhaust gas to generate steam. After the double-layer design, the outer layer of double-layer exhaust pipe 3, double-layer exhaust manifold 6 and turbine housing 7 are designed with water pipe interface for water circulation. The water in the channel generates steam under the action of high temperature of exhaust gas. The steam passes through steam-water separator 10 and is sent to steam turbine 11 through pipeline. Steam turbine 11 drives generator 12 to generate electricity, which adds another part of electric energy to the extended-range electric vehicle, improves the utilization rate of fuel, and reduces high-temperature exhaust gas emission. The gas after steam turbine 11 works is introduced into steam radiator 13 through pipeline, and distilled water is formed after cooling.

After the water in the double-layer exhaust pipe 3 is preliminarily heated to hot water in the first channel 33, it is divided into two paths through the tee 18, one path flows to the second channel 65 of the exhaust manifold, and the other path flows to the third channel 73 of the turbine casing 7. The water is heated by the high temperature of the exhaust gas and boils to generate steam. The steam then passes through the steam-water separator 10 and then enters the steam turbine 11. The steam turbine 11 drives the generator 12 to generate electricity. The water vapor discharged from the steam turbine 11 after working is sent to the steam radiator 13 through a pipeline to cool it into distilled water. The distilled water is sent back to the water storage tank 1 through the return pipe 14 to be reused.
