Description

Piston internal-combustion engine
Technical field
The present invention relates to a kind of piston internal-combustion engine, particularly relate to a kind of two-stroke large diesel engine, it has at least one cylinder, an exhaust manifold is set in the back of cylinder and a pressurized air storage is set in the front of cylinder and has at least one exhaust-gas turbocharger, its turbine can be supplied with waste gas and its gas compressor by exhaust manifold and supply with the pressurized air storage with pressurized air, a charger-air cooler is arranged on the front of pressurized air storage, a device that is used for exhaust gas recirculation wherein is set, and this waste gas can on the pressure side be mixed in the pressurized air with respect to gas compressor.
Background technique
The recirculation of the part by waste gas can reduce NO xDischarge capacity, this is desired.With respect to the gas compressor of exhaust-gas turbocharger, waste gas and pressurized air have such advantage in mixing on the pressure side, and promptly gas compressor and whole exhaust-gas turbocharger therewith can be smaller.In addition, guarantee that whereby responsive compressor impeller does not come in contact with waste gas.
In the equipment of the beginning described type known by US-A-5 611 204, mix with pressurized air in order to make waste gas, an injector device is set in the back of charger-air cooler.Yet in the zone of charger-air cooler back, pressurized air also only has smaller kinetic pressure.In order to realize mixing of waste gas and pressurized air, at this, injector device must carry out strong acceleration to pressurized air, and this causes energy loss.Therefore it upwards is restricted greatly can reaching composite rate.
Summary of the invention
Therefore set out thus, the objective of the invention is, improve the equipment of the described type of beginning, make it not only can reach high composite rate with simple and cheaply mode, and can also be fully or prevent energy loss to a considerable extent.
According to the present invention, this purpose reaches in a kind of configuration of correlation type like this, is about to waste gas and the upstream that is set in charger-air cooler mixing of pressurized air.
Pressurized air carries out spiralling with higher speed in the upstream of charger-air cooler.Therefore the kinetic pressure that higher pressurized air occurs.On the contrary, static pressure is less.In exhaust manifold, only there is static pressure on the other hand.Therefore produce an enough big pressure and fall,, thus, can fully realize starting described principal advantages and still keep structural less expense so that there is not great additional support just can mix more waste gas.Therefore utilize and to avoid known according to measure of the present invention and the described shortcoming of beginning is set and keeps its advantage.Therefore obtain good especially Economy.
The favourable form of implementation of above-mentioned measure is illustrated in all dependent claims with the further formation that conforms with purpose.Like this, waste gas with conform with the zone that the destination is at least partially disposed on the housing of giving vent to anger of gas compressor mixing of pressurized air.The kinetic pressure of pressurized air is the highest there.
Advise in this case, connect the housing of giving vent to anger of the gas compressor of bleed adapter and exhaust-gas turbocharger by the rib of an annular.Obtain a doughnut by this way, it can be as being provided with collection chamber waste gas, that be communicated with the inner chamber of the housing of giving vent to anger.Being communicated with and realizing by the hole of passing common wall simply between collection chamber and the air inlet housing intracoelomic cavity in this case.Therefore such measure can be incorporated into the mixing arrangement one in the compressor housings with favourable mode.Therefore obtain one the simplest, cheaply with the device of compactness, in fact it can not be provided with additional parts.
According to another form of implementation, can be provided with one and rabbet the circulating line that gas compressor is bled and taken over, can be connected in recirculation conduit on every side, this circulating line partly is provided with by the short tube air inlet housing body wall of being told by it and mixes mouth.Can give vent to anger in this form of implementation rib between housing and the suction tude, this usually is satisfactory.
Another can add and use or replace possibility of using and may be, leads to the part of a pressurized air pipeline of charger-air cooler being at least partially disposed on waste gas and mixing of pressurized air from the housing of giving vent to anger of gas compressor.As long as it comprises a diffuser, then mix and to conform with order ground in the realization of the upstream of diffuser.Described measure makes mixing arrangement form good accessibility and therefore can realize a kind of simple additional configurations in an advantageous manner.
Another measure that conforms with purpose may be, a controlling device is set in the zone of the recirculation conduit that can be provided with waste gas.Can adjust desired composite rate by this way.
Another favourable measure may be, charger-air cooler is designed to be provided with the direct cooler of the nozzle that is used to spray into freezing mixture.It can prevent inner pollution in an advantageous manner especially, thereby the supply of waste gas is fully no problem with therefore carry out waste gas in the upstream of charger-air cooler with mixing of pressurized air.
The favourable form of implementation of other of above-mentioned measure is illustrated in remaining dependent claims and by following case description by means of accompanying drawing and can learns in more detail with the further formation that conforms with purpose.
