Inject fuel to force the vehicle to pass at 2 speeds When it is high, it can be τ, and after falling to the setting of five, the description of the invention (3), and then return to the speed limit 'another way to drive forward to the speed change does reach the low speed, the lower limit of speed perception speed is low The step of receiving or supplying the engine ’s speed signal is explained by the periodic setting. The out-of-date near-open system burns to protection. This is the sequential step of this speed limit control. Set the value when the vehicle is in The high-speed i receives the previous control signal transmission, and the opening or low-speed opening degree is suddenly sensed for the car's set value. The opening period is set between the states of the periodic resupply aspect, and the damage is automatically changed. The manufacturing method includes a supply. , The vehicle speed exceeds the step of the lower limit step; the return signal does not output the speed limit and the vehicle setting value that the speed limit control knows, and the setpoint fuel that is maintained. This speed system is related to 'the machine senses that the car receives the output before the fan sets the two-speed setting, and outputs the wheel and the signal processing method of the processing step. Do not switch the speed and the throttle setting, and the vehicle time is the output to be close to the time. In the week, the effect of the unloading is 4 locomotive injection speed and the step value is distinguished from the limit value, and the other control signal is continuously sensed. 俾 · The feedback step 'its throttle signal threshold according to the signal' has exceeded the control when the speed is lower than The news reaches zero, and the setting is set to interrupt the burner. Vehicle jet bow 丨 If the converted vehicle speed is speed, the control signal is output to know the speed of the signal; the other sequence includes the output opening signal as the throttle valve. The vehicle speed is set to pass the time signal. The vehicle speed control throttle threshold is set. After the oil nozzle engine is over-speed, it becomes a signal. The upper limit value of the signal controls the signal to control the change of the combustion process. In addition to the sensory perception step signal, the number is set to be processed periodically when the opening degree is determined. The statutory opening degree is to avoid self-lubricating oil, and use the high-speed and over-speed control output of the vehicle gas breakage data and the high-speed number to deal with the interruption of the step oil, and to control the locomotive injection speed and economy at any time. Receive; when the step is based on, open to all the points, then set the value, if the step;
