Abstract

A condensed liquid outlet port 50, 70 is provided at the lowest point of the gas inlet passage of an i.c. engine 12. The intake air may pass through a cooler, eg an intercooler 24 and a small (eg 0.5mm diameter) orifice 50, fig. 1, may be provided beneath the cooler allowing condensation products, eg water, to escape while minimizing loss of intake air. The water may be discharged or may be fed to a container or tray. Alternatively, the outlet port may be in the inlet manifold 14. The intake passage may receive exhaust gases from an EGR system having an EGR cooler 40 and the outlet port 70, fig.2, may be connected to the exhaust system 30 by drain passage(s) 72-78 which terminate upstream of, or between, exhaust after-treatment devices 32-36. An orifice 50 as in fig.1 may also be provided.

Description

Charge Cooling System
Field of the Invention
The present invention relates to a charge cooling system for an internal combustion engine.
Background of the Invention
Various steps are taken in internal combustion engines to cool the gases, predominantly air, supplied to the engine intake charge system. In exhaust gas recirculation systems the EGR gas is cooled by means of a heat exchanger to allow the introduction of more gas. Engines can also be provided with intercoolers or aftercoolers as charge cooling devices.
A problem which can arise particularly in these cooling devices (but also elsewhere in other parts of the engine intake charge system) is the accumulation of condensation products, predominantly water. The condensation occurs in the intake stream as a natural consequence of the thermodynamic conditions of the intake charge (temperature and pressure) The condensed liquid so produced can cause corrosion or other forms of damage to engine components.
Aspects of the present invention seek to eliminate or at least partially remove such condensed liquid from the system to maintain a robust engine.
Summary of the Present Invention
According to a first aspect of the present invention there is provided an internal combustion engine charge system comprising a gas inlet passage, a condensed liquid outlet port being provided at the lowest region of said passage.
According to a second aspect of the present invention there is provided an internal combustion engine charge and exhaust system comprising a gas inlet passage arranged to be connected to an engine intake, and an exhaust gas system arranged to be connected between the lowest region of the gas inlet passage and the exhaust gas system.
According to a third aspect of the present invention there is provided an engine system comprising an internal combustion engine having a gas intake and a gas outlet, and a gas inlet passage connected to the gas intake, a condensed liquid outlet port being provided at the lowest region of said passage.
Brief Description of the Drawings
Preferred embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, of which: Figure 1 is a diagram of an internal combustion engine gas supply and exhaust system in accordance with a first embodiment of the present invention; and Figure 2 is a diagram of an internal combustion engine gas supply and exhaust system in accordance with a second embodiment of the present invention.
Description of the Preferred Embodiments
The term "charge" as used in this specification means the gas intake to an engine. The charge is usually mostly air, but often includes entrained exhaust gases or other gases and possibly entrained liquid droplets.
Referring now to the drawings, Figure 1 shows an engine gas charge and exhaust system 10 comprising an internal combustion engine 12 with a gas intake manifold 14 and a gas discharge manifold 16. Incoming air passes through a system of inlet pipes or passageways 21, 22 and an intake cooling device 24, typically a heat exchanger. From cooling device 24, the air travels through a passageway 26 to intake manifold 14.
The exhaust from outlet manifold 16 passes into an exhaust pipe system 30 having various aftertreatment devices 32, 34, 36 such as catalytic converters, including oxidation catalysts, soot filters, lean NOx traps and/or SCR catalysts.
As shown, the system employs exhaust gas recirculation (EGR) so that, before the exhaust gases are discharged to the atmosphere at exit 38, a fraction of the exhaust gas is fed back via an EGR cooler 40 to inlet pipe 21.
Although all engine charge intake systems are likely to suffer from undesired condensation at certain regions at certain times, the use of coolers 24 and 40 gives rise to an increased probability of condensed liquid (mostly water) at various points of the pipe network. Accordingly at the lowest point of passageway 22, where condensation products could otherwise accumulate, there is provided a relatively small orifice 50 for the condensation products to escape from the intake system. The orifice size is selected to balance the requirement to allow the condensation to escape while minimizing the loss of useful intake air charge. It is sufficiently large to avoid plugging over time but sufficiently small to minimise intake pressure loss.
Preferred diameters lie in the range 0.3 to 0.8mm, preferably substantially 0.5mm.
The condensation products can simply vent to the atmosphere. Liquid droplets can fall from the system to the ground. Alternatively, they may be fed to an open container or tray, from which they subsequently evaporate into the atmosphere. In an alternative modification they are fed to an enclosed container for storage and possible subsequent removal by the user.
An advantage of the above-described system is that potentially-damaging condensation products are removed from the charge and exhaust gas systems. By efficiently removing these products, a higher throughput of gas is permitted through the system. Thus for example a higher EGR rate may be employed. Also, a more aggressive cooling of the engine inlet charge is possible. The robustness of the engine system is improved and the arrangement permits the implementation of more charge cooling design options because any resulting condensation is manageable. The arrangement is cost-efficient and also provides a degree of control over emissions. The system has the advantage of being a passive system, the controlling parameter being the size of the orifice 50.
Various modifications may be made to the above-described embodiment. For example, the outlet port 50 can be provided at any convenient point along the passage 26 from the outlet of cooler 24 to the intake manifold 14. In particular, the outlet port can be provided in a base part of the cooler 24.
Alternatively, the outlet port can be provided in the inlet manifold 14. More than one outlet port can be provided, and these may be spaced around the lowest region of the charge system in particular along the passageway 26.
There may be more than one inlet passage 22, and each may have a respective cooler 24. There may be more than one exhaust passageways 30.
Figure 2 shows a second embodiment of a gas charge and exhaust system 60, in which the same components have the same reference numerals as in Figure 1. In this embodiment an outlet port or orifice 70 constitutes a bleed orifice which is connected to the exhaust system 30 by a passage or pipe 72. As shown, the passageway 72 opens into the exhaust pipe upstream of the aftertreatment devices 32, 34 and 36.
Thus instead of being discharged from the system, as in the embodiment of Figure 1, the condensate products enter the exhaust flow from the engine 12. This is advantageous, since it avoids a discharge of the condensate products to the environment and enables them to be controlled and monitored together with the other waste products exiting via the exhaust system.
In addition, the second embodiment has all the advantages of the first embodiment. Moreover, the same modifications may be made to it.
Instead of passageway 72 feeding into the exhaust system upstream of the aftertreatment devices, it may be connected via a passageway 74 downstream of the aftertreatment devices.
Alternatively, it can feed via a passageway 76 into a point between two aftertreatment devices of the aftertreatment system, or via a passageway 78 into one of the aftertreatment devices themselves. Any desired combination of passageways 72, 74, 76 and 78 may be employed.
The actual point or points of introduction of the
condensate products into the exhaust system depends on the nature of these products and the architecture of the aftertreatment system. With suitable positioning, the condensate products can be controlled to reduce the proportion of hydrocarbon products.
In addition, there may be provided an outlet port corresponding to orifice 50 of Figure 1 so that part of the condensed liquid leaves at orifice 50 and part passes into the exhaust system. A valve (not shown) may be provided for adjusting the ratio between the parts. The valve may have end settings, in one of which no condensed liquid leaves at the orifice and, in the other of which, all the condensed liquid leaves at the orifice.
It will be understood that the above description of the present invention is susceptible to various modification, changes and adaptations.
