In the present work, we discuss the four stock engine to develop a hydrogen gas engine in the four stock two wheelers most of people affected in the Traffic Jam CO2 gas emission in the recent who research in World Health Organization [WHO]. We developed a safety feature of hydrogen gas in the sea water or salt water in the electrochemical reaction of the anode and cathode of the both electrode plates passing through a current in the steel or aluminum plate to produce a hydrogen gas in the positive terminal plate in the same negative terminal that has produced oxidation in the same electrochemical tank. But we need only hydrogen from the tank to attach another tank of pure water to fill in the area near the tank to dip both hydrogen and oxidation from the tank to split it into pure hydrogen in the tank. When hydrogen gas is fed directly into the engine, it completely backfires. As a result, we use a hydrogen and oxidation of the to split up tank to cut off a backfire from the engine. The engine was developed with a bi-fuel of the hydrogen gas in the modified engine and a carburetor to set a lean mix of the fuel in the carburetor to reduce the fuel flow rate, which is too low, and the air flow rate, which is too high, in the engine, resulting in a higher peak of torque at 13.2 Nm @ 3250 rpm in the hydrogen engine. But petrol engine is higher than the hydrogen engine of the torque is 19.2 Nm @ 2850 rpm to be the also in the also discussed in the paper.
