Abstract
The present invention relates to a turbo supercharging piston type hydrogen fuel engine which mainly comprises a supercharger, an ignition type piston engine, a turbine, an electromagnetic three way valve, a heating interlayer, a hydrogen storage barrel, a controller, a pressure sensor, a needle valve and a flame arrester. After the hydrogen in the hydrogen storage barrel passes through the flame arrester, the pressure of the hydrogen is regulated by the needle valve, and the hydrogen enters a cylinder of the engine to carry out combustion. The generated exhaust gas enters the turbine and promotes the turbine to do work. Then the exhaust gas enters the heating interlayer of the hydrogen storage barrel through the electromagnetic three way valve to heat the hydrogen storage barrel. Finally, the exhaust gas flows in the atmosphere. The side surface of the hydrogen storage barrel is provided with the pressure sensor. When the pressure in the hydrogen storage barrel reaches to a limit value, the controller sends out an instruction to control the switching of the electromagnetic three way valve. The exhaust gas of the turbine is directly drained in the atmosphere and does not heat the hydrogen storage barrel so as to reduce the liberation velocity of the hydrogen. Air is pressurized by a turbo supercharger and enters the cylinder of the engine to carry out combustion with the hydrogen. The supercharger and the turbine do coaxial rotation, and the turbine driven by waste gas drives the supercharger to work.
