Of course, they can be produced at the same time. Additionally, most of them are produced at the same time.
Actually, what is said above is not correct.
The waterproof performance of motors used on water is better, but the waterproof performance of motors used in cars and generators is not so good. However, it is not waterproof. Otherwise, your car will not be able to drive when it rains.
If it is a powerboat or outboard engine, the horsepower is usually less than that of a car engine. It is difficult to say whether the generator power is large or small. If it were used in a power plant, its power would be surprisingly high. But if it's like a generator in a car, the power will be much lower.
As for professional waterproofing methods, in fact, they are not professional.
Because, theoretically bylant, as long as water does not enter the air inlet and exhaust port of an engine, everything will be fine even if other parts are soaked in water.
Actually, a general engine can be sealed as long as it is built into a sealed box (of course, the problem of air inlet and exhaust port must be resolved).
To give the simplest example, have you ever seen a walk-behind tractor? The above diesel engine can be used on ships. And it's very common. Of course, it is not used on speedboats!
You once said that this was true, and this idea is also very good. Personally I think this just solves some problems. You should be able to:
1) The method. Water electrolysis takes a lot of time. For large currents, the motor must provide part of the energy it consumes.
2) The current engine itself presents udoes significant energy loss, such as the above-mentioned resistance to crankshaft rotation, piston action, camshaft, valves, etc., due to drive resistance , heat loss. , etc.
3) The current level cannot achieve a complete internal combustion engine, and the fuel utilization rate is not high. Some of the energy in the fuel will be lost.
4) What is the power of the same engine? Its loss through friction, the energy required to drive the body, the energy of the generator driven by the electrolyzed water, as well as the energy loss caused by incomplete combustion.
If these issues are resolved, this should be feasible.
Personally, I think this will allow for a better re-examination of the hydrogen fuel cell. Hydrogen power generation is directly driven by electrolysis and directly driven by the engine, andthis also avoids the loss of thermal radiation due to incomplete combustion of the fuel cell. engine fuel.
