| Description | Journal: Journal of Physics: Conference Series The device collects the heat energy in the exhaust gas of the car, and realizes the recovery and utilization of the heat energy according to the unique heat energy collection device and the highly efficient linear opposed generator. Through the experiment, it is obtained that the exhaust temperature of the fuel car after doing work can reach about 600-800°C, and if it is a turbocharged engine, the exhaust temperature can reach more than 900°C. Investigations and studies have shown that only 20% to 45% of the energy released by automobile fuel combustion is effectively used, and the rest is dissipated as heat. Among them, the energy carried by engine exhaust accounts for 50%-60% of the total dissipated energy. Therefore, we recover the exhaust gas of the car and convert the low-quality thermal energy into high-quality directly usable electrical energy and use it reasonably. In this work, a set of automobile exhaust heat energy recovery device is designed to modify the automobile exhaust pipe part. In the scheme, the exhaust pipe manifold is converted into a spiral structure, and the opposite linear generator is designed. We use the spiral structure to heat the high-temperature thermal energy in the exhaust gas, heat the internal water to high-temperature, high-pressure saturated steam, and then send it to the opposite linear generator cylinder. Our design makes use of the exhaust sequence of the engine, opposites each other, and works back and forth to achieve the purpose of energy recovery [1]. In this scheme, only the exhaust manifold needs to be modified, and no other consumables other than water are needed during operation. The recovered energy can be used for automobile driving and storage. At the same time, the absorption of high-temperature exhaust gas will also reduce the emission of nitrogen oxides. Through this scheme, energy recovery and the elimination of harmful gases can be achieved at the same time, and the purpose of energy saving and emission reduction can be achieved [2]. |
