Abstract
Description
本発明は請求項1の前文に記載の内燃機関に関する。 The invention relates to an internal combustion engine according to the preamble of claim 1.
内燃機関の効率を高めるべく、内燃機関に排気駆動過給機を装備することは従来から公知である。排気駆動過給運転時ないしターボチャージ運転時、エンジンから排出される排気ガスがタービン内で膨張し、その際、タービンがエンジンに供給すべき燃焼空気を圧縮する圧縮機を駆動する。圧縮済み燃焼空気を所定の温度に冷却するため、圧縮機とエンジンとの間にインタクーラ(過給空気冷却器)が挿入接続される。かかる排気駆動過給運転ないしターボチャージ運転によって、内燃機関の効率が向上する。 In order to increase the efficiency of an internal combustion engine, it is conventionally known to equip an internal combustion engine with an exhaust drive supercharger. During exhaust drive supercharging operation or turbo charge operation, exhaust gas discharged from the engine expands in the turbine, and at that time, the turbine drives a compressor that compresses combustion air to be supplied to the engine. In order to cool the compressed combustion air to a predetermined temperature, an intercooler (supercharged air cooler) is inserted and connected between the compressor and the engine. The efficiency of the internal combustion engine is improved by such an exhaust drive supercharging operation or turbocharge operation.
排気駆動過給機の圧縮機は、圧縮機ロータないし圧縮機インペラと、圧縮機ロータの下流に置かれた圧縮空気案内装置とを利用している。この案内装置は、圧縮機で圧縮した燃焼空気を流れ転向するために用いる複数の静翼(固定案内羽根)を備える。圧縮済み燃焼空気流は、通常、圧縮空気案内装置から出て初めて渦形室を通って導かれ、続いてインタクーラに入る。圧縮済み燃焼空気流は、圧縮空気案内装置の領域で、約220℃の温度を有している。圧縮済み燃焼空気流はインタクーラで約45℃に冷却され、その際、圧縮空気案内装置とインタクーラとの間の流れ損失のために、燃焼空気圧力が低下する。 The compressor of the exhaust-drive supercharger uses a compressor rotor or compressor impeller and a compressed air guide device placed downstream of the compressor rotor. This guide device includes a plurality of stationary blades (fixed guide blades) used to flow and turn combustion air compressed by a compressor. The compressed combustion air stream is usually directed through the vortex chamber only after exiting the compressed air guide and subsequently enters the intercooler. The compressed combustion air stream has a temperature of about 220 ° C. in the region of the compressed air guide device. The compressed combustion air stream is cooled to about 45 ° C. by the intercooler, where the combustion air pressure is reduced due to the flow loss between the compressed air guide and the intercooler.
圧縮空気案内装置の高温領域は汚れの発生を助長する。特に油含有空気の圧縮時、炭化のため圧縮空気案内装置の汚れが生ずる。実際、圧縮空気案内装置を水で掃除することは公知である。しかしこれは、掃除のために別個の媒体が必要になる欠点を持つ。 The high temperature region of the compressed air guide device promotes the generation of dirt. Particularly when oil-containing air is compressed, the compressed air guide device becomes dirty due to carbonization. In fact, it is known to clean compressed air guides with water. However, this has the disadvantage of requiring a separate medium for cleaning.
上述の点から出発して、本発明の課題は新しい内燃機関を提供することにある。 Starting from the above points, the object of the present invention is to provide a new internal combustion engine.
この課題は、請求項1に記載の内燃機関にて解決される。本発明に従い、圧縮空気案内装置の少なくとも幾つかの静翼に孔が設けられ、インタクーラの下流で分岐された冷却済み過給空気が、孔を経て圧縮空気案内装置の領域で未冷却空気流に帰還又は導入される。 This problem is solved by the internal combustion engine according to claim 1. In accordance with the present invention, at least some stationary vanes of the compressed air guide device are provided with holes, and the cooled supercharged air branched downstream of the intercooler passes through the holes into an uncooled air flow in the region of the compressed air guide device. Returned or introduced.
本発明は、圧縮空気案内装置を冷却すべく、静翼に孔を設け、この孔を経て、インタクーラの下流で分岐し、従って冷却した過給空気を、圧縮空気案内装置の領域において未冷却空気流に帰還ないし導入することを特徴とする。 In order to cool the compressed air guide device, the present invention provides a hole in the stationary blade, which branches through the hole downstream of the intercooler, so that the cooled supercharged air is uncooled air in the region of the compressed air guide device. It is characterized by being returned or introduced into the flow.
これにより、別個の冷却媒体を利用せずに、かつ冷却に伴い一層の又は追加的な汚れを生ぜずに、内燃機関の排気駆動過給機の圧縮空気案内装置を冷却できる。従って、本発明によれば、内燃機関の排気駆動過給機の圧縮空気案内装置の効果的な冷却が可能となる。 Accordingly, the compressed air guide device of the exhaust-drive supercharger of the internal combustion engine can be cooled without using a separate cooling medium and without causing further or additional contamination with cooling. Therefore, according to the present invention, it is possible to effectively cool the compressed air guide device of the exhaust drive supercharger of the internal combustion engine.
本発明の有利な実施態様は、従属請求項および以下の説明から明らかである。 Advantageous embodiments of the invention are evident from the dependent claims and the following description.

本発明に基づく内燃機関の排気駆動過給機の圧縮機の範囲で圧縮された燃焼空気は、約220℃の温度を有している。本発明は、圧縮空気案内装置11を冷却すべく、圧縮空気案内装置11の静翼10に孔を設けることを特徴とする。該孔を通して、インタクーラの下流で分岐され、従って冷却済み燃焼空気が、圧縮空気案内装置11の領域において未冷却空気流に帰還ないし導入される。この結果、圧縮空気案内装置11の汚れの恐れなしに圧縮空気案内装置11の特に効果的な冷却が可能となる。

As can be seen from FIG. 1, each
図1から解るように、供給孔17も同様にハウジング16を通って延び、該ハウジング16に、インタクーラの下流で分岐した冷却済み過給空気を供給孔17、従って圧縮空気案内装置11に案内する配管20が接続されている。
