Supplemental system for fuel agency

摘要

A supplemental fuel system for a combustion engine has a primary fuel supply feeding the combustion chamber directly and a supplemental fuel supply which feeds into the combustion air intake. The supply of primary fuel is appropriately reduced or regulated by automatic control and the supply of the supplemental fuel is continuously automatically adjusted to the supply of primary fuel. Initially the supplemental fuel in vapor state is introduced into the air intake until the heat exchange vaporizer system warms up, when there is an automatic shift to the liquid state of supplemental fuel. A temperature compensator in the air intake connected to the supplemental fuel supply holds the temperature of the supplemental fuel at the same temperature as the air with which it is mixed before passing to the final metering orifice and then to the combustion chamber. In case of failure or malfunction of the supplemental fuel supply system, a fail-safe mechanism automatically cuts off the supplemental fuel portion of the system allowing the entire system to operate at restored full power output on the primary fuel.
