Description
Technical field
The present invention relates to a kind of engine installation, especially relate to automobile and use engine installation.
Background technology
At present, the world car recoverable amount surpasses 1,000,000,000, and with annual 3.6% speed increase.Auto pollution discharges to human environment and brings great pressure, and constantly consumes a large amount of non-renewable mineral wealth, human is exploring a kind of pollution less and economical and practical new automobile always.
The automobile that has occurred multiple use hybrid power apparatus of oil and electricity in the prior art, for example battery combustion engine hybrid vehicle or fuel cell hybrid car etc.These mixed power plants are that driving engine and auxiliary power unit are made up, the motion of driven in common driving device drive load.Hybrid power apparatus of oil and electricity comprises power driven system and driving engine, and the battery in the power driven system is that electrical motor provides power, and auxiliary engine drives load operation, can effectively reduce the power consumption of driving engine, reduces disposal of pollutants.But there are little, the bulky characteristics of power in Vehicular battery, and cycle life is low, and charging duration is long, and cost is high, and battery itself also exists serious secondary pollution, has limited being widely used of hybrid power apparatus of oil and electricity.
Summary of the invention
The purpose of this invention is to provide a kind of energy-conserving and environment-protective, safe and reliable natural fuels and pressurized air mixed power plant.
Technical solution of the present invention is: a kind of natural fuels and pressurized air mixed power plant; It comprises natural gas engine, air compressor, storage tank, air motor and driving system; Wherein the clutch end of natural gas engine connects driving system and air compressor respectively; Air compressor is used for for storage tank provides pressurized air, and the air discharge port of storage tank is communicated with air motor, and the clutch end of air motor connects driving system.
Natural gas engine can provide power for air compressor, and mechanical energy is converted into the air pressure ability, is stored in the storage tank; When starting or quicken; Utilize the pressurized air in the storage tank to promote the air motor running, air pressure can be converted into mechanical energy, drive driving system; As the auxiliary power of natural gas engine, the performance when improving acceleration and startup; When the needs glancing impact, natural gas engine can be shut down, and driving system is the rotation of drive air motor under effect of inertia; Regulate pressurized air, make-up gas in storage tank through the air motor control cock; Thereby the braking energy actv. is reclaimed; Whole device be coupled natural gas engine and compressed-air power system, safe and reliable, efficient energy-saving.
Said natural gas engine is liquefied natural gas driving engine or compression natural gas driving engine, can be suitable for existing various natural gas engine, reduces improvement cost.
Advantage of the present invention is: with the coupling of natural gas engine and compressed-air power system, and energy-conserving and environment-protective, with low cost; Capacity usage ratio is higher, has the excellent popularization prospect.

The specific embodiment
Embodiment:
Consult Fig. 1; For a kind of natural fuels and pressurized air mixed power plant are applied in the structural representation on the vehicle; It comprises natural gas engine 1, air compressor 2, storage tank 3, air motor 4 and driving system 5 and the load 6 that is driven by driving system 5; Wherein the clutch end of natural gas engine 1 connects driving system 5 and air compressor 2 respectively; Air compressor 2 is used to storage tank 3 pressurized air is provided, and the air discharge port of storage tank 3 is communicated with air motor 4, and the clutch end of air motor 4 connects driving system 5.
In the present embodiment, natural gas engine 1 can be liquefied natural gas driving engine (LNG) or compression natural gas driving engine (CNG).Air compressor 2, storage tank 3, air motor 4 and driving system 5 are existing installation, are connected to routine techniques between it.
When automobile starting and acceleration, natural gas engine 1 work, its clutch end connects driving system 5, and mechanical energy is passed to 6 runnings of driving system 5 drive load; Storage tank 3 discharges pressurized air, and air pressure can be passed to air motor 4, and air motor 4 runnings can be converted into mechanical energy with air pressure, and air motor 4 clutch ends drive load 6 runnings through driving system 5.Transmit energy to driving system 5 simultaneously through natural gas engine 1 and storage tank 3; Startup and acceleration capability have been improved; When medium and small load condition, natural gas engine 1 to storage tank 3 energy storage, improves the rate of load condensate of natural gas engine 1 through air compressor 2; Reduce time of idle running, improved the efficient of natural gas engine 1.
When automobile needs brake snub; Natural gas engine 1 stops to transmit energy to driving system 5, and the inertia of driving system 5 and load 6 drives air motor 4 runnings, and air motor passes through adjusting control valve to storage tank 3 output pressurized airs; Supplement consumed, thereby with the energy recovery of glancing impact.This moment, natural gas engine 1 was operated under the idling mode, and also drive air compressor 2 runnings simultaneously are converted into the air pressure ability with mechanical energy, are stored in the storage tank 3.
Through existing transmission, clutch system, just can realize the variable speed control of natural gas engine 1 with air compressor 2 and air motor 4 guaranteed that natural gas engine 1 is operated in best combustion gas economic zone, reduce the consumption of natural fuels.
Above-listed detailed description is to the specifying of one of the present invention possible embodiments, and this embodiment is not in order to limiting claim of the present invention, and the equivalence that all the present invention of disengaging do is implemented or change, all should be contained in the claim of this case.
