この考案はターボチャージャにパワリカバリータービン
の機能を兼用させて、パワリカバリータービンを省略し
たターボコンパウンドエンジンに関する。[Detailed Description of the Invention] This invention relates to a turbo compound engine in which the turbocharger also functions as a power recovery turbine, and the power recovery turbine is omitted.
従来ターボコンパウンドエンジンはエンジンの排気によ
り駆動されるタービンの他に、エンジンに直結するパワ
リカバリータービンが設けられていて、排気圧がさらに
エンジンの回転に寄与するようになっている。Conventionally, turbo compound engines are equipped with a power recovery turbine that is directly connected to the engine in addition to a turbine driven by the engine's exhaust gas, so that the exhaust pressure further contributes to engine rotation.
しかし上記構成のものではターボチャージャの他に余分
なターボが付加されて構造が複雑高価になると共に、ダ
クト部などに圧力ロスが生じて逆にエンジンの性能を低
下させるなどの不具合があった。However, with the above configuration, an extra turbo is added in addition to the turbocharger, making the structure complicated and expensive, and there are also problems such as pressure loss occurring in ducts and the like, which conversely deteriorates engine performance.
この考案はかかる不具合を除去する目的でなされたもの
で、ターボチャージャの回転軸とエンジンの間をワンウ

、パワリカバリタービンを省略したターボコンパウンド
エンジンを提供して、構造の簡素化と圧力損失によるエ
ンジン性能の低下などを防止しようとするものである。This invention was made with the purpose of eliminating such problems, and by connecting the rotating shaft of the turbocharger and the engine via a one-way clutch, the turbocharger doubles as a power recovery turbine, and the power is increased. The aim is to provide a turbo compound engine that omits a recovery turbine, thereby simplifying the structure and preventing deterioration of engine performance due to pressure loss.
以下この考案を図示の一実施例について詳述する。This invention will be described in detail below with reference to an illustrated embodiment.
図において１はエンジン、２はターボチャージャで、エ
ンジン１の燃焼室１ａより排出された排気ガスの圧力に

転軸２ｂを介して直結されたコンプレッサ２ｃとよりな
り、コンプレッサ２ｃによって加圧された吸気が上記エ
ンジン１の燃焼室１ａへ過給されるようになっている。In the figure, 1 is an engine, 2 is a turbocharger, a turbine 2a is rotated by the pressure of exhaust gas discharged from the combustion chamber 1a of the engine 1, and a compressor 2c is directly connected to the turbine 2a via a rotating shaft 2b. Thus, intake air pressurized by the compressor 2c is supercharged into the combustion chamber 1a of the engine 1.
また上記エンジン１のクランク軸１ｂにはワンウェイク
ラッチ３を介して駆動軸１ｃが同軸的に設けられている
と共に、この駆動軸１ｃと上記ターボチャージャ２の回
転軸２ｂの間は歯車などの動力伝達機構４を介して連動
されている。Further, a drive shaft 1c is coaxially provided on the crankshaft 1b of the engine 1 via a one-way clutch 3, and a power transmission device such as a gear is used between the drive shaft 1c and the rotating shaft 2b of the turbocharger 2. They are linked via a mechanism 4.
この考案は以上詳述したようになるから、エンジン１が
低速かつ低負荷時には、ターボチャージャ２側の回転よ

増加に伴いターボチャージャ２の駆動力が伝達機構４を
介してクランク軸１ｂへと伝えられてエンジン１の回転
に寄与するようになる。This idea has been explained in detail above, so when the engine 1 is at low speed and under low load, the rotation ratio on the engine 1 side is larger than the rotation on the turbocharger 2 side, so the one-way clutch 3 is in an idling state, and therefore the normal speed is low. When the engine 1 operates as a supercharged engine and the engine 1 reaches a high speed and high load and the rotational speed ratio of the engine 1 and the turbocharger 2 reaches a certain value, the one-way clutch 3 is connected, and from then on as the load increases, the turbocharger 2 The driving force is transmitted to the crankshaft 1b via the transmission mechanism 4 and contributes to the rotation of the engine 1.

となくターボコンパウンドエンジンとしての機能が得ら
れるようになり、複数のターボを必要としないのて構成
が簡単でかつ安価になると共に、ダクト部での圧力損失
も生じないのでエンジン性能を低下させる虞れもない。In other words, it is possible to obtain the function of a turbo compound engine without installing a power recovery turbine like in the past, and the configuration is simple and inexpensive since multiple turbos are not required, and the pressure loss in the duct is reduced. Since this does not occur, there is no risk of deterioration of engine performance.

ーボチャージャの回転が上ることかないため、エンジン
１の筒内圧が上り過ぎてエンジン１が損傷されるなどの
不具合も発生しない。Furthermore, when the rotation of the turbocharger 2 increases and is interlocked with the engine 1 via the one-way clutch 3, the rotation of the turbocharger will not increase any further, causing the cylinder pressure of the engine 1 to rise too much and damage the engine 1. There are no problems such as
