Energy-saving emission-reducing device of internal combustion diesel engine

Abstract

The invention discloses an energy-saving emission-reducing device of an internal combustion diesel engine. The energy-saving emission-reducing device comprises a water supply device, a vaporization chamber and a reduction device, wherein the water supply device comprises a water tank for containing softened water; the vaporization chamber comprises a vaporization chamber body, a vaporization chamber cover and a sealing pad which are combined into a whole through a sealing screw; a floater is arranged in the vaporization chamber; a steam discharge pipe is arranged at the upper end of the vaporization chamber; a water inlet valve, a support sheet, a support base, a steam outlet valve and a compulsive water inlet column are arranged on the vaporization chamber cover; the vaporization chamber is installed on an exhaust pipe of a cylinder; the reduction device comprises a cooling chamber; the cooling chamber is communicated with a steam outlet valve of the vaporization chamber through a soft pipe; and a steam outlet of the cooling chamber is communicated with an air inlet pipe of the cylinder through a soft pipe. According to the invention, the energy-saving emission-reducing device is simple in structure; heat generated by combustion of the internal combustion diesel engine can be sufficiently utilized; and water to be added into the cylinder is quantitatively and automatically supplied to the cylinder of the internal combustion diesel engine through the air inlet pipe of the internal combustion diesel engine, therefore, the purposes of saving oil plants and reducing emission of nitric oxides can be achieved.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing device for a diesel internal combustion engine, in particular to a water-adding auxiliary combustion work device for reducing the emission of nitrogen oxides of a diesel internal combustion engine and saving fuel. Background technique [0002] It is well known that adding water to participate in combustion in the combustion chamber of a piston internal combustion engine has many advantages. Water has the effect of preventing fuel deflagration. After adding a small amount of water into the intake air, you can use low-grade gasoline or diesel, or increase the compression ratio of the engine, both of which can improve the fuel efficiency of the engine. The water in the air has the effect of reducing the temperature of the intake steam. After adding a small amount of water to the intake air, the combustion chamber can inhale denser gas, which increases the actual compression ratio of the engin...
