High-altitude oxygenating starting device of engine

Abstract

The invention discloses a high-altitude oxygenating starting device of an engine. The device comprises a plurality of air cylinders of the engine, an air filter, and an oxygen transmission and distribution device, and is characterized in that the oxygen transmission and distribution device comprises a liquid oxygen storage tank, a liquid pressure regulator, a liquid oxygen gasifier, an oxygen regulator, and an oxygen content meter; the liquid oxygen storage tank, the liquid pressure regulator, the liquid oxygen gasifier, and the oxygen regulator are commercially available products; the liquidoxygen storage tank, the liquid pressure regulator, the liquid oxygen gasifier and the oxygen regulator are respectively and sequentially connected through a oxygen delivery pipe; the front end of theoxygen delivery pipe is connected with an engine air inlet pipe of the air filter; the engine air inlet pipe is connected with the multiple air cylinders of the engine; and the oxygen content meter is arranged on the engine air inlet pipe. According to the high-altitude oxygenating starting device of the engine, the oxygen content in mixed gas in the engine air cylinders in a high-altitude area can reach the standard content, so that the engine can output the design power and the running-out design speed in the high-altitude area, and a series of adverse factors such as the maintenance amount, the high oil consumption and the like when various engines are used in the high-altitude area are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an oxygen supplement starting device for an engine under the condition of hypoxia in a high-altitude area. Background technique [0002] The land surface of the earth is uneven, and the engine can work normally and reach the design power within a certain altitude range, but as the altitude increases, the oxygen content in the air will gradually decrease with the change of the earth's gravity, about The oxygen content in the air decreases by about 10% every time the altitude rises by 1000 meters. The fuel in the mixture in the engine cylinder needs oxygen to support combustion. The amount of oxygen in the mixture directly affects the output power of the engine. The oxygen content in the air is about 20%. When the engine output power can meet the design requirements, as the altitude rises, the oxygen content in the air will gradually decrease, and the engine will affect the reduct...

[0002] The land surface of the earth is uneven, and the engine can work normally and reach the design power within a certain altitude range, but as the altitude increases, the oxygen content in the air will gradually decrease with the change of the earth's gravity, about The oxygen content in the air decreases by about 10% every time the altitude rises by 1000 meters. The fuel in the mixture in the engine cylinder needs oxygen to support combustion. The amount of oxygen in the mixture directly affects the output power of the engine. The oxygen content in the air is about 20%. When the engine output power can meet the design requirements, as the altitude rises, the oxygen content in the air will gradually decrease, and the engine will affect the reduction of the engine output power due to the decrease of oxygen in the air. Some data show that the engine increases every 1000 meters above sea level. The output power is reduced by more than 10%

[0003] Traditional engine improvement technology: taking measures such as turbocharging, intake and exhaust twin turbocharging can only make some partial improvements, and cannot solve the problem of full power output, and cannot solve the problem of fresh air supply that meets the standard oxygen content
