Description
Technical field
The present invention relates to a kind of method and exhaust aftertreatment device of controlling the fuel injection amount of burner; More specifically; The present invention relates to a kind of method and exhaust aftertreatment device of fuel injection amount of such control burner; Wherein control burner, thereby stably reduce waste gas based on the exothermic effect that causes by catalytic filter.
Background technique
Usually, spend because DENG has than higher power of petrol engine and lower fuel, so DENG is widely used in vehicle, construction equipment, boats and ships etc.
Yet DENG is such four stroke engine, wherein; Fuel is sprayed in the motor to burn with the ignition by compression method then; In the self ignition process of fuel, partial combustion can appear owing to the inhomogeneous of air fuel ratio, therefore can produce deleterious particle (waste gas).
Particularly, deleterious particle mainly comprises NO
x, particulate matter (PM) and CO, have and report that deleterious particle accounts for 40% of total air pollution.Therefore, in many countries, stipulated toxic emission, in order to meet this regulation, disclose a kind of exhaust aftertreatment device, this exhaust aftertreatment device is inserted in the outlet pipe to reduce waste gas.
In most of after-treatment devices, the waste gas that in DENG, produces is introduced in the filter with catalyzer, in filter, burns then, thereby reduces exhaust gas discharging.
Yet, give the credit to the low temperature of waste gas when waste gas is introduced filter simply, also developed a kind of new technology, in this new technology, before waste gas is introduced filter, increase the temperature of this waste gas, thereby increase rate of combustion.
In order to increase the temperature of waste gas, proposed a kind of fuel and sprayed after-treatment device and the after-treatment device that uses burner.
Spray in the after-treatment device at fuel, injected fuel is oxidized through catalytic filter and/or preceding catalyst converter the time, thereby increases the temperature of filter, in said filter, collects soot through this reaction.
Yet, in fuel sprays after-treatment device, because the exothermic reaction that utilizes the catalytic oxidation through fuel to occur increases the temperature of waste gas, so need the long time obtain target temperature value.In the situation that excessively sprays into fuel, can discharge unreacted fuel, thereby environmental pollution occur.In addition, typically 180 ℃ of needs or higher temperature come to realize effectively catalytic oxidation, if but utilize exhaust gas driven vehicle with the temperature that is lower than 180 ℃, can't realize catalytic oxidation reposefully so.Particularly, in discharging the situation of unreacted fuel, can discharge milky soot, possibly in driving, cause serious safety problem, also possibly make degraded appearance.
In utilizing the after-treatment device of burner, burner is set between motor and the catalytic filter so that direct heat exhaust gases, and in tail-off or idling mode or engine-driving state operating burner.
In the situation of the method that removes soot through operating burner in tail-off or idling mode,, therefore can stably drive motor owing to operating burner under identical condition.Yet, because operating burner in the saturated state that collected soot arranged of catalytic filter only, thus wittingly shutting engine down with operating burner and inconvenient.
In the situation of the method that removes soot through operating burner in the engine-driving state, must measure the temperature of the waste gas that is introduced into burner and the temperature of burner rear end, to confirm to be supplied to the fuel injection amount of burner.If the front end place at catalytic filter provides preceding catalyst converter, must measure the temperature of the waste gas of catalyst converter before being introduced into so, to confirm to be provided to the fuel injection amount of burner.
Yet, with engine application in the situation of vehicle, the temperature of waste gas and quantity can change fast when powered vehicle.Therefore, compare with the amount that reality is essential, possible errors ground calculates the fuel that sprays into the after-treatment device that uses burner.
The temperature of measuring when the front end place that in the situation of only using catalytic filter, is utilized in catalytic filter or be utilized in the situation of catalyst converter and filter before use before the temperature of front end place measurement of catalyst converter when deciding fuel injection amount, can not reflect the thermal effect that causes by the heat that when the fuel that is provided to burner is oxidized through catalytic filter and/or preceding catalyst converter, is produced.
In other words, be 500 ℃ if use the set temperature value of the after-treatment device of burner, the setting temperature of so rear end (front end of catalytic filter) of burner being located remains in the predictive error scope.But owing to excessive through catalyzer the time, can produce heat, it possibly be 900 ℃ between catalytic filter and preceding catalyst converter or in the rear end of catalytic filter therefore through the temperature of the waste gas after catalytic filter or the preceding catalyst converter through catalytic combustion with unreacted hydrocarbon.
If temperature excessively increases as stated, the durability of filter is understood variation so, and in the poorest situation, filter possibly be damaged.
