Title: Innovations of Peter W Harper
Introduction
Peter W Harper is a notable inventor based in Ramonville St. Agne, France. He has made significant contributions to the field of fuel injection systems, holding 2 patents that showcase his innovative approach to enhancing engine performance.
Latest Patents
One of his latest patents is a "Fuel injection system with fuel mapping." This invention features a digital-analog fuel injection system that controls fuel lean out through a fuel mapping circuit. The circuit provides one of sixteen levels of percent lean out control of the fuel pulse width supplied to an injector. To ensure immediate updates based on engine demands, a pulse generation circuit operates in real time. The fuel mapping circuit makes corrections to the pulse generating circuit on a sampled update basis, utilizing a digital word generated by a microprocessor to control a multiplying digital to analog converter. This converter's reference input represents the present manifold pressure and an offset voltage that accounts for various system variables. The output signal from the fuel mapping circuit is then applied to a pulse generating circuit to control the fuel pulse width delivered to a fuel injector driver.
Another significant patent is the "Quadrature trigger system for sequential fuel injection." This system employs a single lobe timing cam connected to the camshaft of a four-cylinder internal combustion engine. Two proximity sensors positioned in a sensing relationship to the cam generate bilevel electrical signals with a fifty percent duty cycle, spaced ninety electrical degrees apart. These signals are decoded in a logic network to direct fuel injection pulses from either of two pulse generators to the appropriate sequenced fuel injector.
