O princípio da alça do acelerador inclui principalmente dois tipos: acelerador eletrônico e acelerador tradicional .
Acelerador eletrônico
The electronic throttle controls the opening and closing of the throttle through the motor, abandoning the physical connection between the traditional throttle pedal and the throttle. The driver's acceleration intention is converted into an electrical signal through the position sensor on the throttle pedal and transmitted to the engine control unit (ECU). According to the received signal, the ECU accurately adjusts the state of the Trofar através do motor para controlar o suprimento de combustível e a velocidade de operação do motor . Este design permite que o acelerador eletrônico forneça controle mais preciso e melhor desempenho do veículo .
Acelerador tradicional (tomando motocicletas como exemplo)
Traditional throttles, especially early motorcycles, usually use carburetors to mix air and gasoline. The throttle handle controls the throttle valve and needle valve of the carburetors through the throttle cable, thereby controlling the intake and fuel supply. The carburetors are equivalent to the functions of the throttle and the fuel injector, providing power through the mixture of air and A gasolina . Quando o motorista gira a alça do acelerador, a abertura do acelerador aumenta, o fluxo de ar aumenta, a válvula da agulha é ajustada de acordo e o suprimento de combustível aumenta, aumentando assim a energia do motor .
Acelerador da mão
The hand throttle is an auxiliary mechanism, usually installed on the dashboard of the car, used to manually control the engine speed. For gasoline engines, the hand throttle is connected to the throttle through a cable, and the driver can manually fix the throttle opening to control the engine speed. For diesel engines, the hand throttle is connected to the injection pump through the handle to control the engine's Fornecimento de combustível e Flameout .
