さらに本発明に係る過給機の洗浄方法では、内燃機関から導かれた排ガスによって駆動される過給機の洗浄のための洗浄剤が貯留された洗浄剤貯留部と、前記内燃機関へ導く圧縮空気が貯留された圧縮空気貯留部と、該圧縮空気貯留部の前記圧縮空気の一部を前記洗浄剤貯留部へと導く第１配管と、前記洗浄剤貯留部に貯留された前記洗浄剤を前記圧縮空気とともに前記過給機のタービンへと導く第２配管と、を備えた過給機洗浄装置を備えた過給機の洗浄方法であって、前記圧縮空気貯留部から前記内燃機関へ前記圧縮空気を供給するエアブロー時に、前記第１配管を介して供給された前記圧縮空気によって、前記洗浄剤貯留部に貯留された前記洗浄剤が前記第２配管を介して前記過給機のタービンへと供給することを特徴とする。 In yet cleaning method of the turbocharger according to the present invention, a cleaning agent reservoir for cleaning agents for the cleaning of the turbocharger stored driven by flue gas derived from the engine, to the internal combustion engine a compressed air reservoir which compressed air is stored for guiding, the said part of the compressed air of the compressed air reservoir and the first pipe that leads into the detergent reservoir, the reservoir has been the cleaning to the detergent reservoir A supercharger cleaning method comprising a supercharger cleaning device including a second pipe for introducing an agent to the turbine of the supercharger together with the compressed air, wherein the internal combustion engine includes the compressed air reservoir and the internal combustion engine. to when the air blow supplying the compressed air, by the compressed air supplied via the first pipe, the cleaning agent stored in the detergent storing part of the supercharger through the second pipe It supplies to a turbine, It is characterized by the above-mentioned.
洗浄対象となる過給機５は、エアクーラ７の上部にステーを介して設けられ、内燃機関１から導かれた排ガスにより回転駆動される図示しないタービンと、一端にタービンが接続された回転軸と、該回転軸の他端に接続された空気圧縮機とを備えている。この空気圧縮機は、タービンによって得られた回転力が回転軸を介して伝達されて回転駆動させられるようになっており、これにより吸込空気を圧縮する。空気圧縮機によって圧縮された圧縮空気は、エアクーラ７にて冷却された後に、内燃機関１へと供給される。 Turbocharger 5 to be cleaned is provided via a stay on top of the air cooler 7, a turbine (not shown) rotationally driven by a flue gas derived from the internal combustion engine 1, the turbine is connected to one end rotation The shaft includes an air compressor connected to the other end of the rotating shaft. In this air compressor, the rotational force obtained by the turbine is transmitted through a rotary shaft and is driven to rotate, thereby compressing the intake air. The compressed air compressed by the air compressor is cooled by the air cooler 7 and then supplied to the internal combustion engine 1.
タービンは、排ガスを受けて回転するタービン翼から構成されており、タービンケーシング内に収容されている。タービンケーシングは、内燃機関１の排ガスマニフォールド２から排ガスが導かれる過給機入口４と、タービン翼を通過した排ガスをタービン外へと導く過給機出口６とに対して接続されている。 Turbine is composed of turbine blades rotated by the flue gas, it is housed in the turbine casing. Turbine casing is connected to the exhaust manifold 2 of the engine 1 and turbocharger inlet 4 flue gas is led, a supercharger outlet 6 for guiding the flue gas passing through the turbine blade to the turbine out ing.
圧縮空気による内燃機関１の始動が完了すると、制御部１４からの指令によって電磁弁１５が閉とされ、始動用空気タンク１３内に貯留された圧縮空気の供給が停止される。そして、内燃機関１は、図示しない燃料噴射ポンプからの燃料と、過給機５からの圧縮空気とによって通常運転を行う。この通常運転の際に、第２配管９に設けた逆止弁１０によって、過給機５から洗浄粉ホッパー１１ないし始動用空気タンク１３へと向かう流れを防止するようになっている。 When the start-up of the internal combustion engine 1 by the compressed air is completed, the electromagnetic valve 15 is closed by a command from the control unit 14 and the supply of the compressed air stored in the start-up air tank 13 is stopped. The internal combustion engine 1 performs a normal operation with fuel from a fuel injection pump (not shown) and compressed air from the supercharger 5. During this normal operation, a check valve 10 provided in the second pipe 9 prevents a flow from the supercharger 5 toward the washing powder hopper 11 or the start air tank 13.
以上の通り、本実施形態によれば以下の作用効果を奏する。
主配管３から分岐させて圧縮空気を洗浄粉ホッパー１１へと導き洗浄粉を過給機入口４へと供給することとし、始動時およびエアブロー時に合わせて洗浄粉を過給機５のタービンへと供給することとした。これにより、洗浄剤を噴霧するタイミングを特別なタイミングとして把握する必要がなく、圧縮空気を内燃機関１に導くタイミングに合わせて自動的に洗浄剤を噴霧することが可能となり、過給機５のタービンを健全な状態で保つことができる。
また、洗浄粉を供給するタイミングを得るための過給機５の回転数検出装置等が不要となるため、過給機洗浄装置の構造を、より簡便な構造とすることができる。
As described above, according to the present embodiment, the following operational effects are obtained.
The compressed air is branched from the main pipe 3 and the compressed air is guided to the cleaning powder hopper 11 to supply the cleaning powder to the supercharger inlet 4. The cleaning powder is supplied to the turbine of the supercharger 5 at the time of start and air blow. It was decided to supply. Thereby, it is not necessary to grasp the timing of spraying the cleaning agent as a special timing, and it becomes possible to spray the cleaning agent automatically in accordance with the timing of guiding the compressed air to the internal combustion engine 1. The turbine can be kept healthy.
Moreover, since the rotation speed detection apparatus of the supercharger 5 for obtaining the timing which supplies cleaning powder becomes unnecessary, the structure of a supercharger washing | cleaning apparatus can be made a simpler structure.
第２配管９に、過給機５から圧縮空気貯留部１３へと向かう流れを妨げる逆止弁１０を設けることとしたので、内燃機関１の通常運転時において、過給機５側から圧縮空気貯留部１３へと排ガスが逆流することを防ぐことができる。 The second pipe 9, so it was decided to provide a check valve 10 that prevents the flow directed from the turbocharger 5 to the compressed air reservoir 1 3, during the normal operation of the internal combustion engine 1, the compression from the supercharger 5 side it is possible to prevent the flue gas from flowing back to the air reservoir 13.
