(54) СИЛОВАЯ УСТАНОВКА(54) POWER INSTALLATION

Изобретение относитс к машиностроен 1гаю; в частности двигателестроению, а именно к системам охлаждени силовых установок, содержащих дизель и вспомогательный пусковой двигатель.This invention relates to mechanical engineering 1y; in particular, engine building, in particular, to cooling systems of power plants containing a diesel engine and an auxiliary starting engine.

Известны силовые установки, содержащие дизель и вспомогательный пускобой двигатель с автономной воздушной системой охлаждени или с жидкостной .системой охлаждени , объединенной с системой охлаждени дизел . 1} .Power plants are known that contain a diesel and auxiliary start-up engine with an autonomous air cooling system or with a liquid cooling system integrated with a diesel cooling system. one} .

В известных конструкци х пусковые двигатели с жидкостным охлаждением не примен ют на дизел х с воздушным охлаждением и - наоборот.In known designs, liquid-cooled starting engines are not used on air-cooled diesel engines and vice versa.

Целью изобретени вл етс обеспечение ВОЗМОЖНОСТИ применени унифииирован11ых пусковых двигателей на дизеп к жидкостного и воздушного охлаждени путем использовани дизельного топлива в качестве охлаждающего тела.The aim of the invention is to provide the POSSIBILITY of using diesel engine start-up engines for diesel and air cooling by using diesel fuel as a cooling body.

Дл достижени поставленной цели трубопроводы подвода и отвода охлаждающей жидкости пускового двигател жидкостноГО охлаждени подсоединены к топливному баку и образуют замкнутый контур шфкуЛЯЩ1И охлаждающей жидкости через бак и рубашку охлаждени блока пускового двигател .In order to achieve this goal, the piping for supplying and discharging the coolant of the liquid-cooled starting engine is connected to the fuel tank and form a closed loop of the cooling fluid through the tank and the cooling jacket of the starting engine.

Дл осуществлени циркул ции может быть использован насос с приводом от пускового двигател .A pump driven by a starting motor can be used to circulate.

На чертеже представлена схема уста10 новки.The drawing shows an installation diagram.

Установка содержит дизель 1, например воздушного охлаждени с топливной системой 2, включающей топливный бак 3 и вспомогательный пусковой двигатель жид15 костного охлаждени 4, снабженный трубопроводом подвода 5 и отвода 6 охлаждающей жидкости (дизельного ;топлнва) от рубащки охлаждени , а также насосом 7 дл осуществлени циркул ции дизельного The installation comprises a diesel engine 1, for example, air cooling with a fuel system 2 comprising a fuel tank 3 and an auxiliary engine for bone cooling 4, equipped with a supply line 5 and a drain 6 for cooling fluid (diesel) from the cooling jacket, as well as a pump 7 for carrying out diesel circulation

Claims

20 fuel from the fuel tank 3 through the pipeline 5 to the cooling jacket of the starting engine 4 and through the pipeline 6 back to the diesel fuel tank 3. 3973 The Silovoy installation operates as a fighter. The fuel used in a diesel engine from fuel tank 3 through line 5 is poured into the cooling jacket of auxiliary start-up engine 4 by pump 7, which is included in the engine start cooling system, and after cooling the starting engine block 4, fuel returns through line 6 to fuel tank 3 and be used to feed a diesel into the combustion chamber. Thus, an auxiliary start-up engine, the cooling jacket of the block of which is not connected to the diesel engine cooling system, but is connected to its fuel system, can be applied to air-powered diesel engines and other coolants. Claims 1. The power plant contains a diesel with a fuel system including 84 fuel tank and an auxiliary liquid-cooled starting engine equipped with pipelines for supplying and discharging coolant from the cooling jacket of its unit, distinguishing it with standardized engines for diesel and air cooled diesel engines, the supply and removal pipelines for the starting engine coolant are connected to the fuel tank and form a closed circuit for circulating coolant through the tank and the cooling jacket of the engine starting unit.

2. Installation according to claim 1, that is to say that the pump with the drive from the starting engine is included in the circulation circuit. Information sources taken into account during the examination 1, USSR Copyright Certificate No. 499413, cl. F 01 P 3/20, 1976.
