Abstract
SECONDARY FUEL MODULATING VALVE
Abstract of the Disclosure A valve for controlling the flow of secondary fuel to a turbo-charged diesel engine. The valve incorporates a cylinder, a first inlet port which couples the cylinder to a secondary fuel reservoir, a second inlet port which couples the cylinder to the engine's turbo-charger, a discharge port which couples the cylinder to a secondary fuel inlet of the engine, and a piston which is slidably displaceable within the cylinder to controllably open and close the discharge port in response to changes in the turbo-charger's boost pressure. The piston moves between a closed position in which the piston blocks secondary fuel flow from the first inlet port to the discharge port, a first range of open positions in which the piston allows progressively increasing amounts of secondary fuel to flow from the first inlet port to the discharge port, and a second range of open positions in which the piston allows progressively decreasing amounts of secondary fuel to flow from the first inlet port to the discharge port.
