本考案はアフタクーラつきエンジンでデュアルサーキッ
トアフタクーラの制御装置に関するものである。[Detailed Description of the Invention] The present invention relates to a control device for a dual circuit aftercooler in an engine with an aftercooler.
デュアルサーキットではアフタクーラ出口空気温度が低
くなるので部分数荷時騒音、および排気ガスの臭いが問
題になっていた。With dual circuits, the air temperature at the aftercooler outlet is low, which causes problems with noise and exhaust gas odor when loading parts.
本考案は上記の事情に鑑みなされたものであって、その

費馬力を低減させることにある。The present invention was developed in view of the above circumstances, and its purpose is to prevent air from flowing into the aftercooler during partial load or when the engine water temperature is low, thereby preventing a drop in the aftercooler outlet air temperature, and reducing noise. The objective is to eliminate the odor of generated and exhaust gas, and to reduce the driving power consumption for cooling water by separating the water pump from the water pump of the engine cooling circuit.
以下、本考案を図面を参照して説明する。Hereinafter, the present invention will be explained with reference to the drawings.
図面中１はエンジン２に具備されたアフタクーラであり
、３はラジ毛−タ、４は水ポンプである。In the drawing, 1 is an aftercooler provided in the engine 2, 3 is a radiator, and 4 is a water pump.
水ポンプ４の吐出側は第１配管５を介してアフタクーラ
１の入口側に通じている。The discharge side of the water pump 4 communicates with the inlet side of the aftercooler 1 via a first pipe 5.
アフタクーラ１の出口側は第２配管６を介してラジェー
タ３の高温側に通じており、ラジェータ３の低温側は第
３配管７を介して水ポンプ４の吸込側に通じている。The outlet side of the aftercooler 1 communicates with the high temperature side of the radiator 3 via a second pipe 6, and the low temperature side of the radiator 3 communicates with the suction side of the water pump 4 via a third pipe 7.
また、図面中８はエンジン２の冷却用ラジェータである
。Further, 8 in the drawing is a radiator for cooling the engine 2.
水ポンプ４は電動モータ９で駆動されるものであり、電

びエンジン水温が低いときには電動モータ９は停止する
ものである。The water pump 4 is driven by an electric motor 9, and the control unit of the electric motor 9 receives a signal from the lever position of the fuel pump 10 during partial load and a detection signal from the water temperature at the outlet side of the cooling radiator 8. When the electric motor 9 is turned on and the engine water temperature is low, the electric motor 9 is stopped at partial load and when the engine water temperature is low.
しかして、水ポンプ４の、駆動により冷却水は第１配管
５を介してアフタクーラ１に入り、アフタクーラ１を出

ンプ４にもどる。By driving the water pump 4, cooling water enters the aftercooler 1 via the first pipe 5, and cooling water leaving the aftercooler 1 enters the radiator 3 and returns to the water pump 4 via the third pipe 7.
そして、部分負荷時又はエンジン水温が低いときには電
動モータ９の制御部に停止信号が入り、この電動モータ
９が停止し水ポンプ４が停止する。Then, at partial load or when the engine water temperature is low, a stop signal is input to the control section of the electric motor 9, and the electric motor 9 is stopped and the water pump 4 is stopped.
このためにアフタクーラ１に冷却水が流れない。For this reason, cooling water does not flow into the aftercooler 1.
これによりアフタクーラ１の出口空気温度の低下を防ぐ
。This prevents the outlet air temperature of the aftercooler 1 from decreasing.

御装置である。As described in detail above, the present invention includes an aftercooler cooling circuit which returns the cooling water discharged from the water pump 4 to the water pump 4 via the aftercooler 1 and the radiator 3, and which is separate from the engine cooling circuit. The water pump 4 is separate from the water pump in the engine cooling circuit, and the water pump 4 is driven by an electric motor 9 that stops rotating upon receiving a stop signal during partial load or when the engine water temperature is low. This is a control device for a dual circuit aftercooler.

低減させることができる。Therefore, when the engine is under partial load or when the engine water temperature is low, the drive of the water pump 4 is stopped to prevent the cooling water from flowing into the aftercooler 1, thereby preventing a drop in the outlet air temperature of the aftercooler 1, thereby preventing noise generation and exhaust gas odor. In addition, the water pump 4 can be made separate from the water pump of the engine cooling circuit, and the horsepower consumption for driving the cooling water can be reduced.
