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.
内燃機関の効率および出力を高めるべく、内燃機関に排気駆動過給装置を装備することは既に公知である。排気駆動過給装置の場合、エンジンから排出された排気ガスがタービンで膨張し、該タービンが圧縮機を駆動し、エンジンに供給すべき燃焼空気を圧縮機で圧縮する。圧縮した燃焼空気を所定の温度に冷却すべく、圧縮機とエンジンの間にインタークーラを設けている。かかるクーラによって、例えばディーゼル又はガソリンエンジンを含む内燃機関の効率を向上できる。 In order to increase the efficiency and output of an internal combustion engine, it is already known to equip an internal combustion engine with an exhaust drive supercharger. In the case of an exhaust drive supercharger, exhaust gas discharged from an engine is expanded by a turbine, the turbine drives a compressor, and combustion air to be supplied to the engine is compressed by the compressor. In order to cool the compressed combustion air to a predetermined temperature, an intercooler is provided between the compressor and the engine. Such coolers can improve the efficiency of internal combustion engines including, for example, diesel or gasoline engines.
タービン並びに圧縮機を持つ上述の単段式排気駆動過給装置は、実現可能な過給圧力並びに実現可能な効率に関してそれらの経済的限界に突き当たり、そのため内燃機関の効率と出力を一層高めるべく、多段式、特に2段式の排気駆動過給装置が実用化されている。該過給装置では、内燃機関のエンジンに高圧過給装置と低圧過給装置を付設している。高圧過給装置は、エンジンから出る排気ガス流を供給され膨張させる高圧タービンを備え、該タービンは高圧圧縮機を駆動し、該圧縮機はエンジンに供給すべき燃焼空気流を圧縮する。高圧圧縮機とエンジンとの間にはインタークーラを設けている。 The above-described single-stage exhaust-drive supercharger with a turbine and a compressor has reached their economic limits with respect to achievable supercharging pressure and achievable efficiency, and therefore to further increase the efficiency and output of the internal combustion engine, A multi-stage, particularly a two-stage exhaust drive supercharger has been put into practical use. In the supercharging device, a high-pressure supercharging device and a low-pressure supercharging device are attached to the engine of the internal combustion engine. The high pressure supercharger comprises a high pressure turbine that is supplied and expanded with an exhaust gas stream exiting the engine, which drives a high pressure compressor that compresses the combustion air stream to be supplied to the engine. An intercooler is provided between the high-pressure compressor and the engine.
低圧過給装置は、高圧タービンから出る排気ガス流を供給され膨張させる低圧タービンを有している。このタービンは低圧圧縮機を駆動し、該圧縮機は、エンジンに高圧圧縮機を介して供給すべき燃焼空気流を予圧縮する。低圧圧縮機と高圧圧縮機との間に、通常、別のインタークーラを設けている。 The low pressure supercharger has a low pressure turbine that is supplied and expanded with an exhaust gas stream leaving the high pressure turbine. This turbine drives a low-pressure compressor that precompresses the combustion air stream to be supplied to the engine via the high-pressure compressor. Usually, another intercooler is provided between the low-pressure compressor and the high-pressure compressor.
従って2段式排気駆動過給装置を備えた内燃機関の場合、内燃機関のエンジンに2つの過給装置、即ち高圧過給装置と低圧過給装置が付属している。これら両過給装置は、従来は両方ともエンジンに据え付けていた。各シリンダ列に別個の排気駆動過給装置を利用するV形構造のエンジンでは、2段式排気駆動過給装置は、エンジンに固定すべき過給装置の数が4台に増え、各シリンダ列に各々高圧過給装置と低圧過給装置を設けている。 Therefore, in the case of an internal combustion engine equipped with a two-stage exhaust drive supercharger, two superchargers, that is, a high pressure supercharger and a low pressure supercharger are attached to the engine of the internal combustion engine. Both of these turbochargers have been installed in the engine in the past. In a V-type engine using a separate exhaust drive supercharger for each cylinder row, the number of superchargers to be fixed to the engine is increased to four in the two-stage exhaust drive supercharger. Each is provided with a high-pressure supercharging device and a low-pressure supercharging device.
エンジンに固定ないし支持すべき過給装置の数が増大すると、過給装置の大きな所要空間のために取付上の問題を生ずる。更に内燃機関の強度と振動挙動に悪影響が生ずる。 As the number of supercharging devices to be fixed or supported on the engine increases, mounting problems arise due to the large required space of the supercharging devices. In addition, the strength and vibration behavior of the internal combustion engine are adversely affected.
本発明の課題は、上述の問題から出発して新しい内燃機関を提供することにある。 The object of the present invention is to provide a new internal combustion engine starting from the above-mentioned problems.
この課題は、請求項1記載の内燃機関によって解決される。本発明に基づき、低圧過給装置を別個のモジュールとして形成し、低圧過給装置を別個のフレームないし架台に支持することでエンジンから切り離す。 This problem is solved by the internal combustion engine according to claim 1. In accordance with the present invention, the low pressure supercharger is formed as a separate module and is separated from the engine by supporting the low pressure supercharger on a separate frame or cradle.
本発明では、少なくとも2段式の排気駆動過給装置を備えた内燃機関において、低圧過給装置を別個のモジュールとして形成し、低圧過給装置を別個のフレームないし架台で支持するようにしてエンジンから切り離す。かくして、内燃機関の強度と振動挙動が単段過給式内燃機関と変わらなくなる。低圧過給装置の取付けや組立における場所的問題は回避できる。低圧過給装置を別個のモジュールとして形成するので、単段式排気駆動過給装置付きの既存の内燃機関に、エンジンや高圧過給装置の構造を変更することなく、低圧過給装置を簡単に追加装備できる。 In the present invention, in an internal combustion engine provided with at least a two-stage exhaust drive supercharger, the low pressure supercharger is formed as a separate module, and the low pressure supercharger is supported by a separate frame or gantry. Disconnect from. Thus, the strength and vibration behavior of the internal combustion engine are no different from those of the single-stage supercharging internal combustion engine. Location problems in the installation and assembly of the low pressure supercharger can be avoided. Since the low-pressure supercharger is formed as a separate module, the low-pressure supercharger can be easily changed to an existing internal combustion engine with a single-stage exhaust-drive supercharger without changing the structure of the engine or the high-pressure supercharger. Can be equipped with additional equipment.
高圧過給装置をエンジンと共に共通のフレームや架台で支持し、その際、高圧過給装置とエンジンを特に1つのモジュールとして形成するとよい。 The high-pressure supercharger is supported by a common frame or gantry together with the engine, and at this time, the high-pressure supercharger and the engine are particularly preferably formed as one module.
