Abstract

"SISTEMA DE LIMITAçãO DE VELOCIDADE DE VEìCULO". A invenção refere-se a um limite de velocidade de veículo que quando se concretiza por meio do empobrecimento da ignição, a quantidade de gás não-queimado aumenta, CO e HC aumentam, a carga do catalisador aumenta e a vida útil do catalisador é significativamente reduzida. A Figura A ilustra um controle de divisão, um primeiro limiar de velocidade de veículo e um segundo limiar de velocidade de veículo, o qual é maior do que o primeiro limiar de velocidade de veículo, o controle normal é executado até o primeiro limiar de velocidade de veículo, o controle de decréscimo é executado entre o primeiro limiar de velocidade de veículo e o segundo limiar de velocidade de veículo e o controle de decréscimo e o controle de ignição (empobrecimento da ignição) são executados acima do segundo limiar de velocidade de veículo. A Figura B ilustra a operação de fechamento e abertura de uma válvula solenóide (19) e a Figura C ilustra o controle de ignição, concretamente, o caso da ignição está empobrecida ou não. A velocidade de veículo é suavemente diminuída por meio do controle de decréscimo em um primeiro estágio e é seguramente diminuída por meio do controle de ignição em um segundo estágio. à medida que a combustão continua, sob controle de decréscimo, a quantidade de gás não-queimado é reduzida e um nível de emissão pode ser melhorado."VEHICLE SPEED LIMITATION SYSTEM". The invention relates to a vehicle speed limit which when realized by ignition depletion, the amount of unburned gas increases, CO and HC increase, catalyst loading increases and catalyst life is significantly reduced. reduced. Figure A illustrates a split control, a first vehicle speed threshold and a second vehicle speed threshold, which is higher than the first vehicle speed threshold, normal control is performed to the first speed threshold. decrease control is performed between the first vehicle speed threshold and the second vehicle speed threshold and the decrease control and ignition depletion control are performed above the second vehicle speed threshold. . Figure B illustrates the closing and opening operation of a solenoid valve (19) and Figure C illustrates ignition control, specifically whether the ignition is depleted or not. Vehicle speed is smoothly decreased by decreasing control in a first stage and is safely decreased by ignition control in a second stage. As combustion continues, under decreasing control, the amount of unburned gas is reduced and an emission level can be improved.
