The invention relates to an engine power system, and aims to provide a pneumatic and internal combustion hybrid system based on multi-stage utilization of afterheat of cooled water. According to the system, an air inlet pressure stabilization box of a pneumatic engine is connected with an air storage tank through a high pressure air pipeline; an air cylinder body and an air cylinder cover of a water-cooled internal combustion engine, a water pump and a pipeline form loop circulation; a circulation loop of the cooling water in the water-cooled internal combustion engine is divided into three stages; the first stage of the circulation loop is small circulation of the internal combustion engine body; the second stage of the circulation loop and the third stage of the circulation loop are respectively added into a pneumatic engine air cylinder and a water and air heat exchanger; and the stages of circulation loops are switched by turning on and turning off an electronic thermostat. The system makes full use of the afterheat of the cooling water in the internal combustion engine, so that the working environment of the pneumatic engine is improved, the circulation output power of the pneumatic engine is improved effectively, and the air consumption rate of the pneumatic engine is reduced finally; furthermore, the energy consumption of the internal combustion engine is reduced; and the dynamic property and the economy of the power system are improved.

The invention discloses energy-saving non-negative pressure equipment. The equipment comprises a water supply main pipe, a voltage stabilization tank and a water tank, wherein a double-valve-position floating ball valve is arranged on a pipe body, the voltage stabilization tank is connected to the part, on the front part of the double-valve-position floating ball valve, of the water supply main pipe, the voltage stabilization tank is connected with a first water pump for supplying water to a water pipeline, the voltage stabilization tank is used for keeping the water inlet pressure of the first water pump stable, the water tank is connected with the water supply main pipe and arranged behind the double-valve-position floating ball valve, the double-valve-position floating ball valve can be opened or closed according to the liquid level in the water tank, the water tank is connected with a second water pump, and the second water pump is used for pumping water in the water tank to the water pipeline of a user. The invention discloses a design method of energy-saving non-negative pressure equipment. According to the secondary water supply energy-saving device and the design method, the supply and demand parties can be integrally optimized, the benefits of water supply enterprises are protected, the operation electric charge of a box-type pump station is saved, and social resources are saved.

The invention discloses a breathing boost device of an automobile engine, comprising an air inlet arranged in a shell at the front end of an automobile, wherein the rear port of the air inlet is connected with the air inlet of an engine air filter; the air outlet of the engine air filter is connected with an air inlet manifold of the engine; and the air inlet manifold of the engine is connected with the air inlet of the engine. By using the wind speed and the wind pressure generated at the front end of a driving car (including various sedan cars, camions and other vehicles), the breathing boost device can automatically adjust to increase the inlet pressure of the automobile engine, improve the engine power, reduce oil consumption and save energy. In addition, the breathing boost device is simple in structure, low in cost and not only easy for implementation on a new vehicle, but also applicable to modification of an old vehicle.
