Embodiment
Below in conjunction with diagram, preferred embodiment of the present utility model is described in detail.
During engine operation, fuel oil must become suitable ratio with the air sucking, and could form the mixed gas that can burn; The ratio of this fuel oil and air is called air fuel ratio.In theory, every gram of minimum air grams that fuel oil perfect combustion is required, is called chemically correct fuel, and this chemically correct fuel is roughly 14.7, and one kilogram of fuel oil perfect combustion needs the air of 14.7 kilograms in theory.When actual mixing ratio is greater than chemically correct fuel, gas heavy wool is few, burning is complete, oil consumption is low, it is little to pollute, but output power is less; When actual mixing ratio is less than chemically correct fuel, although output power is large, the few oil of gas is many, incomplete combustion, oil consumption is high and pollute greatly.
The air fuel ratio of motor (as petrol engine) is maximum at 12 to 13 o'clock power, minimum oil consumption in 16 o'clock, minimum in 18 left and right contaminant concentration.Therefore, in order to reduce oil consumption and to reduce and pollute, should use the weak mixture that air fuel ratio is larger as far as possible, only motor during in heavy duty state (during open loop situations) rich mixture is just provided, and motor (during closed loop state) when light-load state should provide weak mixture.The heavy duty state here or open loop situations are that mean engine is provided with according to the exhaust oxygen content of the lambda sensor feedback of automobile and adjusts fuel injection quantity, refer generally to automobile in startup, idling, anxious accelerate or full-power state under; Under this state, in order to export enough power, the air fuel ratio of motor is roughly 12.5 left and right.The light-load state here or closed loop state refer to that motor adjusts fuel injection quantity according to the exhaust oxygen content of the lambda sensor feedback of automobile, and under this state, the air fuel ratio of motor is roughly chemically correct fuel (i.e. 14.7 left and right).
Please refer to Fig. 1, Fig. 1 is the structural representation of the first preferred embodiment of automobile oxygenerator of the present utility model.The automobile oxygenerator of this preferred embodiment comprises source of compressed air 41, nitrogen oxygen segregation apparatus 42 and motor air supply pipe 43.Source of compressed air 41 is for providing pressurized air; Nitrogen oxygen segregation apparatus 42, for pressurized air being carried out to nitrogen oxygen lock out operation, is exported high-concentration oxygen; Motor air supply pipe 43, for described high-concentration oxygen and air are mixed into after oxygenation air, exports this oxygenation air to motor, mixes and burns with fuel oil.In motor air supply pipe 43, be provided with control valve 431, this control valve 431 can, according to the oxygen fuel oil ratio of motor, be controlled the output quantity of high-concentration oxygen.
When the automobile oxygenerator of this preferred embodiment is worked, first source of compressed air 41 provides corresponding pressurized air to nitrogen oxygen segregation apparatus 42,42 pairs of these pressurized air of nitrogen oxygen segregation apparatus carry out nitrogen oxygen lock out operation, output high-concentration oxygen, the oxygen concentration of this high-concentration oxygen is generally 30% to 90%; Then under 431 of the control valve in motor air supply pipe 43 controls, in motor air supply pipe 43, high-concentration oxygen and air are mixed into oxygenation air, the oxygen concentration optimum range of this oxygenation air is 23% to 25%, the oxygen concentration of this oxygenation air is a little more than the oxygen concentration of normal atmosphere, can make in-engine fuel oil burn more fully, the oxygen concentration that simultaneously also can not make mixed air is too high and produce too much oxynitrides.
The oxygen concentration of this oxygenation air is according to controlling for air quantity, the oxygen concentration of high-concentration oxygen and the tolerance of high-concentration oxygen of mixing.Because the oxygen concentration of the air quantity for mixing and high-concentration oxygen is generally design load (substantially constant), the tolerance of therefore controlling high-concentration oxygens by control valve 431 can make the oxygen concentration of oxygenation air be positioned at 23% to 25% optimum range.
Last motor air supply pipe 43 exports mixed oxygenation air to motor, mixes and burns with fuel oil; Because the motor of existing automobile all be take the air fuel ratio of open loop situations as 12.5 left and right (oxygen fuel oil ratio is 2.62 left and right), the air fuel ratio of closed loop state is that 14.7 left and right (oxygen fuel oil ratio is 3.08 left and right) arrange.And in air the lower area of oxygen concentration, no matter although motor is can reach this air fuel ratio in open loop situations or closed loop state, all cannot reach corresponding oxygen fuel oil ratio, caused the burning of fuel oil insufficient, environment has been caused to pollution.The automobile oxygenerator of this preferred embodiment, by oxygenation air is input in motor, make motor when operate in open loop state state, the oxygen fuel oil ratio of motor is 2.88 to 3.12, motor is when closed-loop working state, and the oxygen fuel oil ratio of motor is 3.38 to 3.68, and the oxygen fuel oil ratio of motor is equal to or higher than normal level, the burning of fuel oil is more abundant, has reduced pollution on the environment.In-engine air does not carry out supercharging simultaneously, has avoided the generation of noise and phenomenon of detonation.
The automobile oxygenerator of this preferred embodiment, controls the oxygen fuel oil ratio of the motor in different conditions by control valve, make motor always in best working state, and the burning of fuel oil is more abundant, has reduced pollution on the environment.
