Abstract

Se describe una disposicion de conversion para convertir un motor de encendido por chispa para operar con combustible gaseoso. La disposicion deconversion incluye un controlador electronico que opera sobre varios principios novedosos para proveer comportamiento/respuesta superior y para reducir lasemisiones de escape. El controlador de acuerdo con la invencion asume el control completo de sincronizacion de encendido por chispa cuando se habilitael modo combustible gaseoso y generasenales de encendido de chispa independientes adaptadas al combustible gaseoso. El controlador también generauna senal de inyeccion de combustible gaseoso modulada por ancho de pulso independiente que controla una válvula solenoidede inyector electronicade alta velocidad para suministrar combustible gaseoso al motor. La velocidad de inyector variable se usa para compensar el rango dinámico del motor. Unesquema de aprendizaje en bloque de conjunto doble novedoso se usa paraproveer control de combustible eficiente en motores con disposiciones decontrol a lazo cerrado y recirculacion de gas de escape. Además, provee un modo de refuerzo de potencia con nafta permitiendo potencia extra cuandose demanda por torsor máximo del motor. La ventaja es una disposicion de suministro de combustible eficiente que provee todas las ventajas de loscombustibles gaseosos mientras que conserva la capacidad de potencia de los combustibles líquidos, y minimizalas emisiones de escape.A conversion arrangement for converting a spark ignition engine to operate on gaseous fuel is described. The conversion arrangement includes an electronic controller that operates on several novel principles to provide superior behavior / response and to reduce exhaust emissions. The controller in accordance with the invention assumes full control of spark ignition timing when the gaseous fuel mode is enabled and independent spark ignition signals are matched to the gaseous fuel. The controller also generates an independent pulse width modulated gaseous fuel injection signal that controls a high speed electronic injector solenoid valve to supply gaseous fuel to the engine. Variable injector speed is used to compensate for the dynamic range of the engine. A novel dual assembly block learning scheme is used to provide efficient fuel control in engines with closed loop control and exhaust gas recirculation arrangements. In addition, it provides a power boost mode with gasoline allowing extra power when demanded by maximum engine torque. The advantage is an efficient fuel supply arrangement that provides all the benefits of gaseous fuels while retaining the power capacity of liquid fuels, and minimizing exhaust emissions.
