Power generator and internal combustion engine unit for boats 10

The invention relates to a unit for boats, consisting of a cooled power generator and a power generator that drives it, directly attached internal combustion engine cooled by outside water, in particular diesel engine.

Generators with a water-cooled diesel engine that drives an air-cooled power generator (generator) are known for boats. These are built in a size of around 2CJ k to hO KVA and are relatively noisy without additional soundproofing measures. The high volume is largely due to the air noise from the generator cooling.

.25 The object of the invention is to provide a unit of the type mentioned at the outset which, with sufficient cooling and high performance and with little technical effort has a low noise level.

According to the invention, this object is achieved in that

• · · · «a tit ta ·«

Generator and motor have a common cooling water flow »whereby the one coming from the generator * the Generator heat dissipating line with the cooling water inlet

of the motor is connected.

Such a unit is very quiet with a high cooling capacity. Due to the lack of air cooling, the technical Relatively little effort, and the unit is particularly small * The small construction makes itself special noticeable when the unit is encased in a noise-absorbing manner, since due to the low noise level of the Aggregate, the encapsulation must be less strong than usual. This means that the external dimensions of the capsule are also small. Furthermore, the unit is very inexpensive because it is lower

^ Measures for noise insulation are required.

Although it is known per se to cool electricity generators with water, this has not hitherto been done in the case of generator sets for boats, in particular not in a size range from k to HO KVA.

It is preferably proposed that the line supplying water to the generator be connected to the outside of the boat is. A simple discharge of the water is achieved if the exhaust of the engine is the outlet for the cooling water from the generator and engine.

An embodiment of the invention is shown in the drawings and will be described in more detail below described. Show it:

The power-generating unit 1 has an internal combustion engine, in particular a diesel engine 2, on the output shaft of which an electric power generator 3 is attached directly, so that the motor and generator form a unit. The diesel engine 2 also has an air filter k for the intake air, a cylinder head 5, a starter 6 and an exhaust 7.

The diesel engine 2 also drives a water pump 8, which is fastened on the side opposite the generator 3 and whose inlet is connected via a line to the outside of the boat below the water level. The pump 8 sucks in the water that surrounds the boat and delivers it from the pump outlet 10 via a first line 11 inside the generator 3. With this outside The fresh water (outside water) taken from the boat is cooled by the generator 3. The one heated by the generator Water enters a second line 12 from the generator, which is connected to the cooling water inlet 13 of the diesel engine connected is. The water, which is slightly heated by the generator 3, then cools the diesel engine and then passes through it the exhaust 7 together with the exhaust gases.

The advantages of the invention are particularly evident when using a diesel engine and with an output of H to kO KVA.
