Description
Technical field
The present invention relates to a kind of in combustion air mixed fluid fuel and gaseous fuel make the double fuel explosive motor of its burning.
Background technique
In recent years, the combustion gas restriction of vehicle is strengthened day by day, wherein, the lorry and the bus that carry explosive motor relatively realize that the innoxious requirement of waste gas is strong day by day.In this waste gas countermeasure, have the improvement engine body the burning form, reduce harmful matters such as the black smoke be contained in the waste gas, NOx, HC, CO discharge capacity gimmick and remove the gimmick of harmful matter by the waste gas cleaning plant of being located at exhaust steam passage, in most of occasions, and with the corresponding toxic emission restriction of two gimmicks.As the former a waste gas countermeasure, the double fuel explosive motor that also burns with gaseous fuel and liquid fuel has been proposed.In the fuel supply form of this explosive motor, have with dispersed state gaseous fuel is supplied to the premixing mode in the combustion air and gaseous fuel sprayed the spray regime supply in the firing chamber by gas ejector.
In spray regime, though similarly in compression stroke, spray supply gas fuel with liquid fuel by gas ejector, have from compression stroke initial stage to mid-term supply gas fuel near the low pressure high voltage supply form (the special fair 6-39916 communique of Japan, real fair 3-55810 communique) supplying with form and the top dead center of compression stroke, spray supply gas fuel substantially simultaneously with liquid fuel.In most of occasions, this gas ejector is by controlling time for spraying and emitted dose from the control oil of actuating the pump conveying.Actuating the fuel-injection pump that pump and liquid uses similarly utilizes engine power synchronously to drive.In the special fair 6-39916 communique of Japan, by 1 sparger feed fluid fuel and gaseous fuel.The premixing mode can for example see in Japanese special fair 6-43814 communique and the clear 62-500674 communique of Te Biao, wherein, under the gaseous fuel that will adjust to low pressure is mixed into state in the combustion air, supplies with by gas-entered passageway.
The advantage that have the double fuel explosive motor that acts as a fuel with the natural-gas as described above low public hazardsization that realize waste gas simultaneously and fuel cost reduce, even but can be no problem in the occasion of newly-designed motor, in the application of the existing motor that is equipped on the lorry that used and bus etc. difficulty very.In order to make existing motor double fuelization, must add gas ejector being set and actuating pump or actuate drive system that pump uses etc. at least, but must carry out the bigger transformation of motor and change the outfit etc., burden incurs great expense.
As described above, in existing fuel supply mode, have spray regime and premixing mode, have speciality respectively, but also respectively have shortcoming.In spray regime, owing in the way of compression stroke, spray supply gas fuel, so, can prevent from non-inflammable gas is discharged in the waste gas, and can strictly limit the delivery volume of gaseous fuel.Yet, owing in the compression stroke way, spray supply gas fuel, so, be difficult to equably gaseous fuel is distributed in the combustion air, be easy to produce partial combustion.Particularly near the occasion of top dead center, spraying simultaneously supply gas fuel with liquid fuel, because the pressure in the firing chamber is higher, so, fuel gas can not be distributed to equably the liquid fuel of combustion air and spraying, the result may produce black smoke.
For this point, in the premixing mode, owing in advance gaseous fuel is distributed in the combustion air that is inhaled in the firing chamber, so, but therefore relative combustion even air ground mixed fuel, can realize perfect combustion.Yet,, have the problem that is easy to produce so-called unburned gas owing in the beginning intake stroke, the combustion air of air inclusion fuel is directed into the firing chamber.This be because, at the initial stage of intake stroke, because intake valve and exhaust valve both sides are for opening the valve state, so a part that flow into the gaseous fuel in the firing chamber is gone out to the exhaust passage from exhaust valve one thruster.
