Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 小ターボから大ターボへの切換えをスムーズ になし得ると共に、切換時のスモークの発生を防止する ようにしたディーゼルエンジンのシーケンシャル過給装 置を提供する。 【構成】 ディーゼルエンジン1の排気管4に小ターボ 2と大ターボ3とを並設し、排気ガス量が少ないときに は小ターボ2を用い、排気ガス量が多くなるにしたがっ て大ターボ3に切換えるようにしたシーケンシャル過給 装置において、小ターボ2のタービン流入管5に、排気 ガスの一部を大ターボ3のタービン3tへ導く予回転管 28を設け、その予回転管28に、小ターボ2から大タ ーボ3に切換えるに先立って開弁される予回転弁29を 設けことを特徴とする。 (57) [Summary] [Purpose] To provide a sequential supercharging device for a diesel engine, which can smoothly switch from a small turbo to a large turbo and prevents smoke from being generated at the time of switching. [Structure] A small turbo 2 and a large turbo 3 are installed in parallel in an exhaust pipe 4 of a diesel engine 1. When the exhaust gas amount is small, the small turbo 2 is used, and the large turbo 3 is switched to as the exhaust gas amount increases. In the sequential supercharging device described above, the turbine inlet pipe 5 of the small turbo 2 is provided with a pre-rotation pipe 28 that guides a part of the exhaust gas to the turbine 3t of the large turbo 3. It is characterized in that a pre-rotation valve 29 that is opened prior to switching to the large turbo 3 is provided.
