Abstract
Several embodiments of fuel injection systems for internal combustion engines wherein certain components of the engine are lubricated directly by lubricant supplied by a lubricant pump and the lubricant pump also supplies lubricant to a fuel injection pump. In some embodiments, the fuel delivered to the injection pump is mixed with the fuel pumped by the injection pump for delivery to the engine through an injection nozzle.
