The air heat exchanger 7 and the gas heat exchanger 16 are connected in series with a low-temperature cooling water device for exchanging heat between the air and gas passing through them. The air inlet pipe 13 and the gas inlet pipe 14 are respectively connected to the engine via flexible connections.

[0019] Both the air collection chamber 10 and the gas collection chamber 15 are fixed to the common base 11 by the collection chamber bracket 12. The air heat exchanger 7 and the gas heat exchanger 16 are respectively provided with a low-temperature water outlet and a low-temperature water inlet, which are respectively sealed and connected to the inlet and outlet of the low-temperature cooling water device. The low-temperature cooling water device uses an engine low-temperature water pump to realize the delivery of low-temperature water. The air heat exchanger 7 and the gas heat exchanger 16 are connected by a pipeline. The air booster 2 and the air distribution chamber 6 are sealed and connected by an air transmission pipeline, and an air throttle valve 5 is provided on the air transmission pipeline between them. An air filter 4 is sealed and connected to the air booster 2 by an air transmission pipeline. An air valve 3 is installed on the gas pipeline between the two. One end of the gas booster 22 is provided with an air inlet pipe, and a gas valve 23 is installed on the air inlet pipe. The other end of the gas booster 22 is sealed and connected to the gas distribution chamber 19 through a gas pipeline. A gas throttle valve 21 is installed on the gas pipeline between the two. A housing structure 20 is provided on the common base 11 to cover the air cooling device and the gas cooling device to protect their strength. The air booster 2 and the gas booster 22 are installed on the upper end of the housing structure 20. An exhaust gas distribution pipe 1 is provided between the air booster 2 and the gas booster 22 for automatic distribution between the two.

[0020] A high-temperature cooling water device is connected in series on the air heat exchanger 7 and the gas heat exchanger 16.

Air booster 2 obtains the kinetic energy of engine exhaust gas through exhaust gas distribution pipe 1, and boosts the air to 150-200 kPa. Air heat exchanger 7 reduces the air temperature to about 60°. The gas passes sequentially through the gas valve 23, gas turbocharger 22, gas throttle valve 21, gas distribution chamber 19, gas heat exchanger 16, and gas collection chamber 15, and finally enters the engine cylinder through the gas intake pipe 14. The gas turbocharger 22 and the air turbocharger 2 share the exhaust gas distribution pipe 1 and are equipped with an automatic distribution valve to distribute the exhaust gas at a ratio of 3:1. The heat exchanger reduces the gas temperature to about 55°C to prevent the gas from decomposing due to high temperature. The engine cryogenic water pump outlet sequentially passes the cooling water through the cryogenic water inlet, the gas heat exchanger 16, the cryogenic water outlet, and the air heat exchanger 7, and then enters the engine cooling circuit to achieve the function of pre-cooling the air and gas. When starting up in winter, the air and gas are heated by high-temperature water.
