Embodiment 1

[0020] Embodiment 1, a gasified powder internal combustion engine, including a feed system, a gasified fuel preprocessor, an air-fuel ratio regulator (18), an automatic control unit (15), an emission processor, etc., such as figure 1 shown.

[0021] The combustible solid adopts crop straw, which is pre-processed into a powder with a particle size of less than 10 mm and a water content of less than 12%. And add additives such as 2.5% dolomite powder, as powder fuel (2).

[0022] The feeding system is composed of a hopper (1), a feeder (7), a feeding controller (6), and a feeding port (8). The feed controller (6) supplies the powdered fuel (2) to the gasifier (3) in good time according to the instruction of the automatic control unit (15).

[0023] The fuel preprocessor is composed of a gasifier (3), a cyclone separator (4), a tar processor (5), a fan (13), an air volume regulator (14) and the like. The gasification furnace (3) is equipped with an igniter (9), a fire grate (1...

Embodiment 2

[0027] Embodiment 2, combustible powder direct injection internal combustion engine, such as figure 2 As shown, it includes an internal combustion engine body, a fuel preprocessor (50), an electronically controlled fuel injector (32), an automatic controller (46), an emission processor (40) and the like.

[0028] Combustible solids are pre-processed into fine powder fuels with a particle size of less than 5 microns, a water content of less than 5%, and a small amount of additives. The powdered fuel (2) is stored in the fuel tank (53), and the feeding pump (52) supplies the fuel pre-processor (50) in good time according to the instruction of the automatic control unit (15). A check valve is provided between the delivery pump (52) and the fuel preprocessor (50) to prevent the pretreated fuel from flowing back. The preconditioned fuel is passed to electronically controlled fuel injectors (32).

[0029] Electronically controlled fuel injector (32) is divided into in-cylinder in...

Abstract

An internal-combustion engine using combustible powder as fuel consists of fuel material preprocessor, mixer, fuel jet and discharging processor. The said combustible powder is prepared from plant residues, coal or combustible wastes and additives.

Description

technical field [0001] A combustible powder internal combustion engine relates to a technical method of a new internal combustion engine using combustible solid powder as energy. Background technique [0002] The internal combustion engine is a power machine in which fuel is burned in the engine cylinder to generate heat energy, which is converted into mechanical energy. It includes crankshaft connecting rod mechanism, gas distribution mechanism, fuel system, lubrication system, cooling system, control system, etc. Generally, the fuel for internal combustion engines comes from petroleum. Those that use diesel as fuel are called diesel engines, and those that use gasoline as fuel are called gasoline engines. [0003] Since the Gulf War, oil prices have continued to rise. The energy problem of internal combustion engine is a difficult subject before us. Due to the limited oil resources on the earth, according to the latest data, the oil reserves discovered so far in the CIS...
