ABSTRACT:
The present invention relates to an improved fluid vaporizer for use in conjunction with an internal combustion engine comprising intake and exhaust valves, each of the valves including seats. An exhaust valve seat insert is provided for receiving and directing unheated fuel around the exhaust valve seat whereby the fuel is preheated by the cylinder. An intake valve seat insert receives the heated fuel from the exhaust valve seat and directs the now heated fuel from the intake valve seat and into the cylinder for increased combustion efficiency. A valve stroke adjuster is also provided for increasing or decreasing the amount the inlet valve is opened.
