Abstract:

A fuel supply system is provided for an internal combustion engine. The system comprises a fuel control valve metering fuel to the inlet of the engine and a governor for monitoring the output of the engine and adjusting the fuel control valve. A first fuel of low quality is fed to the inlet of the engine through a first valve regulating the supply of the first fuel. A fuel mixture controller responds to output signals from the governor and adjusts the position of a second valve for regulating the supply of a second fuel of high quality. The first and second fuels are combined in a mixture before being fed to the fuel control valve and the inlet of the engine.
