Abstract
A fuel mixer box is provided for supplying a fuel mixture to each cylinder of an engine. The fuel mixer box includes a housing defining a chamber for receiving combustion gases generated by the engine during the operation thereof. Input conduits have inputs connectable to a fuel source for receiving fuel therefrom and outputs. Output conduits have inputs communicating with the outputs of corresponding input conduits and outputs connectable to corresponding cylinders of the engine. In addition, the output conduits communicate with the chamber to receive combustion gases to be mixed with the fuel to provide the fuel mixture. In addition, fuel may be supplied directly to the output conduits through corresponding venturis within the housing.
Claims17
A fuel mixer box for providing a fuel mixture to each cylinder of an engine, comprising:
- a first input conduit having an input connectable to a fuel source for receiving fuel therefrom and an output;
- a first output conduit having an input communicating with the output of the first input conduit and an output connectable to a first cylinder of the engine;
- a injection conduit having an input connectable to the fuel source and an output communicating with the output conduit;
- and
- a housing having an interior, and an opening therein for allowing combustion gases generated by the engine to enter the housing.
A fuel mixer box for providing a fuel mixture to each cylinder of an engine, comprising:
- a housing defining an outer chamber and an inner chamber isolated from the outer chamber, the housing having an opening therein for allowing the outer chamber to receive combustion gases generated by the engine during the operation thereof;
