Abstract
The invention relates to the field of automobile industry and particularly relates to a combustion gas turbine suitable for automobiles. The combustion gas turbine adopts a combustion gas turbine technology in which closed waste gas circulation and opened combustion gas circulation are adopted together. The combustion gas turbine comprises a gas pressing machine, an exhaust pipe, a power turbine, transmission shafts, a combustion chamber, a high-pressure gas pipe, a fuel mixed gas inlet pipe, an oil injecting mouth, an electromagnetic valve, a plunger type gas compressor and a gas storage tank, wherein the gas pressing machine, the high-pressure gas pipe, the combustion chamber and the power turbine form the closed waste gas circulation; the plunger type gas compressor, the gas storage tank, the electromagnetic valve, the fuel mixed gas inlet pipe, the combustion chamber, the power turbine and the exhaust pipe form the opened combustion gas circulation; the two circulation types are combined in the combustion chamber, heat exchange is achieved, then the power turbine is driven to act, and power can be output by the transmission shafts at the two ends. By adopting the technology, the oil consumption of the combustion gas turbine during low load and idling can be reduced, two ends of the transmission shafts can be used for outputting the power, the mode that the two ends of the transmission shafts can be used for outputting the power is consistent with that when a conventional four-stroke engine is adopted, the overall arrangement of the engine is convenient; when the automobile brakes for reducing the speeding, part of energy can be recycled by adopting a method in which a dragging compressor is adopted for increasing the pressure of the gas storage tank.
Description
Technical field
The present invention relates to auto industry field, is the gas turbine that a kind of applicable automobile uses.
Background technique
At present, what motor car engine generally adopted is four-stroke gasoline engine and diesel engine, and they exist that vibration noise is large, pollution from exhaust emission is high and the shortcoming such as the thermal efficiency is low.Although that existing gas turbine has advantages of is lightweight, volume is little, it is low to discharge, it can discharge large quantity of exhaust gas when low-load and idling, causes unnecessary thermal loss, causes excessive oil consumption, fails so far to assemble widely automobile.So, only have the problem that solves gas turbine high oil consumption when low-load and idling operation, it could meet oil consumption and the emission request of automobile.
Summary of the invention
Technological scheme of the present invention is adopt a kind of waste gas to remain silent gas turbine technology that circulation and combustion gas opening circulate and deposit, and waste gas is remained silent to circulate and can be reduced exhaust loss, and combustion gas opening circulates and can keep machine internal pressure basicly stable.This gas turbine comprises gas compressor, outlet pipe, power turbine, transmission shaft, firing chamber, high-pressure air pipe, fuel mixture inlet pipe, oil nozzle, electromagnetic valve, plunger type air compressor and gas holder; Gas compressor, high-pressure air pipe, firing chamber and power turbine form the waste gas circulation of remaining silent; Plunger type air compressor, gas holder, electromagnetic valve, fuel mixture inlet pipe, firing chamber, power turbine and outlet pipe form the circulation of combustion gas opening.Two circulate in that firing chamber is mixed and heat-shift after promote power turbine acting, finally by the transmission shaft outputting power at two ends.
For the needs that burn, by plunger type air compressor, fresh air is pressed in gas holder, the air pressure of gas holder will be higher than the pressure of blower outlet.Oil nozzle can spray different oil masses under the different operating modes of gas turbine, can pass through the size of electromagnetic valve adjusting air inflow quantity, makes fuel mixture meet the requirement of air fuel ratio.Outlet pipe accesses and leads in atmosphere between power turbine and gas compressor gas, this means that the pressure of power turbine airflow outlet end approximates atmospheric pressure, and fuel mixture inlet pipe leaked-in air flow approximates the air mass flow that outlet pipe is discharged.
For example, gas turbine is when low-load and idling work, oil nozzle sprays fuel with pulse mode, electromagnetic valve also sprays the air of corresponding chemical equivalent with pulse mode, only have the waste gas of small part to discharge from outlet pipe, overwhelming majority waste gas is sucked and in gas turbine, forms circulation by gas compressor, thereby has reduced exhaust loss.When braking automobile deceleration drags gas turbine, oil nozzle and electromagnetic valve are all in closed condition, fuel mixture inlet pipe leaked-in air flow equals zero, the air mass flow that outlet pipe is discharged also equals zero, the temperature of gas turbine can obviously not reduce during braking and fuel cutting-off, because now gas turbine is operated in closed circulation state.
Technique effect of the present invention is to adopt technique scheme can reduce the oil consumption of gas turbine when low-load and idling; Power can be transmitted in the two ends of transmission shaft, consistent with traditional four stroke engine, is convenient to engine compartment layout; When braking automobile slows down, can be with the method recovery section energy that drags compressor and improve gas holder pressure.

Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
As shown in FIG., gas compressor (1), high-pressure air pipe (6), firing chamber (5) and power turbine (3) form the waste gas circulation of remaining silent; Plunger type air compressor (10), gas holder (11), electromagnetic valve (9), fuel mixture inlet pipe (7), firing chamber (5), power turbine (3) and outlet pipe (2) form the circulation of combustion gas opening.The air-flow of two circulations mixes also and promotes power turbine (3) acting after heat-shift in firing chamber (5), final by transmission shaft (4) outputting power at two ends.
For the needs that burn, by plunger type air compressor (10), fresh air is pressed in gas holder (11), the air pressure of gas holder (11) will be higher than the pressure of gas compressor (1) outlet.Oil nozzle (8) can spray different oil masses under the different operating modes of gas turbine, can pass through the size of electromagnetic valve (9) adjusting air inflow quantity, makes fuel mixture meet the requirement of air fuel ratio.Outlet pipe (2) accesses and leads in atmosphere between gas compressor (1) and power turbine (3), the pressure that this means power turbine (3) outlet end approximates atmospheric pressure, and fuel mixture inlet pipe (7) leaked-in air flow approximates the air mass flow that outlet pipe (2) is discharged.
For example, gas turbine is when low-load and idling work, oil nozzle (8) is with pulse mode ejection fuel, electromagnetic valve (9) also sprays the air of corresponding chemical equivalent with pulse mode, only have the waste gas of small part to discharge from outlet pipe (2), overwhelming majority waste gas is sucked and in gas turbine, forms circulation by gas compressor (1), thereby has reduced exhaust loss.Automobile is when brake deceleration drags gas turbine, oil nozzle (8) and electromagnetic valve (9) are all in closed condition, fuel mixture inlet pipe (7) leaked-in air flow equals zero, the air mass flow that outlet pipe (2) is discharged also equals zero, the temperature of gas turbine can obviously not reduce during braking and fuel cutting-off, because now gas turbine is operated in closed circulation state.
