Description
【考案の詳細な説明】 本考案は空気冷却器付き内燃機関に関する。[Detailed explanation of the idea] The present invention relates to an internal combustion engine with an air cooler.
従来、この種内燃機関を塔載した車両、自動車
等においては、カーヒータ用の温水として、シリ
ンダヘツド出口の冷却水をシリンダヘツド出口と
サーモスタツト入口との間の冷却水路から分岐し
て使用していた。 Conventionally, in vehicles, automobiles, etc. equipped with this type of internal combustion engine, the cooling water at the cylinder head outlet is used as hot water for the car heater by branching it from the cooling water channel between the cylinder head outlet and the thermostat inlet. Ta.
カーヒータは、機関の始動後直ちに作動するこ
とが望ましいが、かかる従来のものにおいては、
機関の始動直後はサーモスタツトが閉じているた
め、シリンダヘツド出口とカーヒータからの温水
の戻り口である水ポンプの吸込口との間の水圧の
差が小さく従つて冷却水の流量が小さくなること
から、始動直後におけるカーヒータの効きが悪い
という問題点があつた。 It is desirable for car heaters to operate immediately after the engine starts, but in such conventional heaters,
Immediately after the engine starts, the thermostat is closed, so the difference in water pressure between the cylinder head outlet and the water pump suction port, which is the return port for hot water from the car heater, is small, so the flow rate of cooling water is small. Therefore, there was a problem that the car heater was not effective immediately after starting the car.
本考案は上記に鑑みなされたもので、機関始動
直後のカーヒータの作動を迅速化せしめた内燃機
関を提供することを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide an internal combustion engine in which the car heater can be activated immediately after the engine is started.

岐してカーヒータ２に接続される。 One embodiment of the present invention will be described below with reference to FIG. 1. 1 is an internal combustion engine, 2 is a car heater, 3 is a
is an air cooler, 4 is a radiator, 5 is an engine cylinder jacket, 6 is an oil cooler, 7 is a water pump, 8 is a cooling water outlet pipe from the engine cylinder head, 9 is a thermostat, and 10 is an air cooler 3 is a cooling water inlet pipe, 11 is a cooling water outlet pipe from the air cooler 3, 12 is a cooling water bypass pipe, 13 is a cooling water return pipe from the car heater 2, 14 is an outlet of the radiator 4 and a water pump 7. This is a cooling water inlet pipe that connects to the suction port, and the configuration thereof is the same as that of the conventional one. 15 is a hot water pipe to the car heater 2. The hot water pipe 15 branches from the cooling pipe line 10 between the discharge port of the water pump 7 and the cooling water inlet of the air cooler 3 and is connected to the car heater 2 .
上記機関において、冷却水は第１図矢印の如く

抵抗分だけ高くなつているので、カーヒータ２内
に温水が流れ易くなり、カーヒータ２に充分な量
の温水が供給される。 In the above engine, the cooling water flows as shown by the arrow in FIG. 1 to cool the air in the engine 1 and the air cooler 3. At this time, the water pressure in the cooling inlet 10 to the air cooler 3 is higher than the water pressure in the bypass pipe 12 or the cylinder head outlet cooling water pipe 8 by the resistance of the air cooler 3, so This makes it easier for hot water to flow, and a sufficient amount of hot water is supplied to the car heater 2.
本考案は以上のように構成されており、本考案
によれば、水圧の高い空気冷却器入口への冷却管
路中から分岐した温水をカーヒータに導くように
