Horizontal low-temperature insulating air cylinder and vehicle power system taking gas as power source

Abstract

The invention relates to a horizontal low-temperature insulating air cylinder which comprises a casing, an internal cylinder, a distributor, a cylinder pipeline of a pipeline control system, a neck tube, a supporting piece and an insulating layer. The invention further relates to a vehicle power system taking gas as a power source, which comprises the horizontal low-temperature insulating air cylinder, a gasifier, a pressure regulating tank, an air engine, an operation and control mechanism, a power source control pedal, a chassis and a vehicle body; the power source control pedal is connected with a power input part of the operation and control mechanism; a power output part of the operation and control mechanism is connected with a control rod of a control valve of the pressure regulating tank; a gas outlet of the horizontal low-temperature insulating air cylinder is connected with a gas inlet of the gasifier through a connecting pipe; a gas outlet of the gasifier is connected with a gas inlet of the pressure regulating tank through a connecting pipe; a gas outlet of the pressure regulating tank is connected with a gas inlet of the air engine through a connecting pipe; a power output part of the air engine is connected with a power input part of a transmission system of the chassis; and the power source control pedal is connected with the control end of the control valve of the pressure regulating tank through the operation and control mechanism.

Description

technical field [0001] The invention relates to a low-temperature heat-insulating gas cylinder and a power system of an automobile, in particular to a power system of an automobile using gas as a power source. Background technique [0002] With the rapid development of the world economy, the global energy crisis is imminent. In recent years, my country's automobile industry has developed rapidly, and automobile production has increased year by year, which has brought about more and more prominent energy and environmental problems. As a country with a large energy demand, my country's energy demand is increasing rapidly year by year. Due to the relative shortage of domestic fossil energy, especially oil and natural gas production, my country's energy supply will increasingly rely on the international market in the future. renewable energy. Traditional cars use gasoline engines, diesel engines, liquefied natural gas engines, etc. These engines consume a lot of oil and gas res...

Problems solved by technology

If the valve 14 at the gas release port 13 has been opened before the pressure boost regulating valve 16 is automatically closed, the amount of gas supplied from the gas discharge port cannot be exactly the same as the amount of gas delivered into the gas cylinder 1 by the pressure boost regulating valve 16. Equal, if the gas supply volume is greater than the input gas volume, the gas supply pressure will drop, and if the gas supply volume is less than the input gas volume, the pressure in the gas cylinder 1 will rise, which eventually leads to the frequent closing and opening of the boost regulating valve 16 , and the problem of unstable air supply pressure also occurs

It can be seen that the welded insulated gas cylinders of said document are not suitable for use in pneumatic motors because they cannot provide stable pressure.

[0009] Due to the limitation of the space size of the car, especially the pneumatic engine as the power machine must be installed on the chassis, so the existing vertical cryogenic insulating gas cylinders cannot be used in medium-sized cars, especially small cars, and can not be used in large cars. more troublesome
