Hydrogen and oxgen combustion has the same power as a gasoline engine ? pls automotive engineers only TY?

I have tried to put a voltage intensifier to increase the current in the electrolysis of water by using a special catalyst. I just remember the first law of electrolysis and I try to make a device that is needed to ionize the water more efficiently to split the compund water. the current is directly proportional for the ionization of waters compound to have production of hydrogen and oxygen.Ffor a short time I luckily started the engine with just the combustion of hydrogen and oxygen with the same power as of a gasoline engine w/out modyfying any part of the engine. by just installing it to the engine of a 1988 Sunny Nissan. the exhaust is water vapor. but I didn’t run it from a long distance. having problem with the moisture that makes my motor oil diluted. some of the water vapor are seeping to the piston rings. and the oil in the crank case is starting to have a thick sludge that affects the performance of the engine. Stan meyer Is also using a device called a voltage intensifier circuit
