Abstract

This invention describes a fuel system for an internal combustion engine of the diesel type which is completely compatible with methanol and other low cetane liquid fuels. The fuel system is also capable of handling methanol liquid fuel, and other low cetane highly corrosive liquid fuels, of materials fully compatible with the fuel and adapted for long term durability use. Further, a fuel system is disclosed that is free of particulates of less than one micron in size thereby providing superior long term durability protection against scoring within the fuel pump and fuel delivery injectors. The invention also provides a fuel system comprising primary and secondary fuel filters, a fuel pump, and the fuel injectors designed to provide acceptable durability and reliability despite the lack of lubricity in methanol and similar fuels.
