Abstract
Patente de Invenção:<B>"MéTODO E DISPOSITIVO PARA CONTROLAR A VELOCIDADE EM MARCHA LENTA DE UM MOTOR"<D>. Um método e um aparelho para controlar as condições de operação em marcha lenta de um motor de combustão interna de um veículo motorizado, mediante a variação da potência extraída do gerador de tensão (W4) pelo circuito elétrico (L-BA). A velocidade de marcha do motor é detectada por uma unidade lógica de controle (ME), por exemplo, um microcontrolador, em relação à freq³ência do gerador de tensão dentro de uma faixa de velocidades de marcha predefinida; pela mesma unidade lógica de controle (ME), o estado conectado ou desconectado da carga elétrica de corrente alternada (L) do veículo é detectado e, dependendo das informações recebidas relativas ao estado conectado ou desconectado da carga elétrica (LO) ao gerador de tensão (W4) e a velocidade de marcha do motor, a unidade lógica de controle (ME) provoca a ativação ou desativação de uma chave eletrónica de controle (SCR3 - figura 4) para ligar o gerador de tensão (W4) à terra.Invention Patent: <B> "METHOD AND DEVICE FOR CONTROLLING THE SPEED OF AN ENGINE." <D>. A method and apparatus for controlling the idling operating conditions of an internal combustion engine in a motor vehicle, by varying the power extracted from the voltage generator (W4) by the electrical circuit (L-BA). The running speed of the motor is detected by a logic control unit (ME), for example, a microcontroller, in relation to the frequency of the voltage generator within a predefined running speed range; by the same logic control unit (ME), the connected or disconnected state of the alternating current electric load (L) of the vehicle is detected and, depending on the information received regarding the connected or disconnected state of the electric load (LO) to the voltage generator (W4) and the engine speed, the logic control unit (ME) causes the activation or deactivation of an electronic control switch (SCR3 - figure 4) to connect the voltage generator (W4) to earth.
