What is the principle of the two wires in the reverse switch?

The principle of the two wires in the reverse switch is controlled by the controller motherboard for forward and reverse rotation, with the internal processor of the controller handling the conversion. There is a reverse signal wire on the reverse gear controller, which can be connected to the on-off switch on the right handlebar along with the negative terminal. The direction of the power input pulley on the engine side remains unchanged, while the reverse output gear inside the transmission engages with the output shaft, driving the output shaft to rotate in the opposite direction, ultimately causing the wheels to rotate backward for reversing. Below is an extended introduction: Reverse function: The controller has an added reverse function, which is disabled during normal riding. When the user stops, pressing the reverse function key enables assisted reversing, with the reverse speed not exceeding 10 km/h. High-speed control: The latest microcontroller designed specifically for motor control is used, incorporating a new BLDC control algorithm suitable for high-speed (below 6000 rpm), medium-speed, or low-speed motor control.

Why does the throttle jerk and feel weak when accelerating?

Here are the reasons for throttle jerking and weak acceleration: 1. Fuel quality issues: If low-grade gasoline is used, the octane rating is insufficient, leading to weak acceleration, reduced engine power, and increased fuel consumption. Additionally, carbon buildup in the fuel system, fuel pump failure, or clogged fuel filters can also cause a drop in engine power. 2. Insufficient oil pressure: Low oil pressure and poor sealing. Poor-quality oil can also lead to insufficient engine power, reduced fluidity, and increased driving resistance. 3. Engine issues: Besides fuel, the engine also requires air. If components like the air filter or throttle body are clogged or malfunctioning, resulting in insufficient air intake, the car will experience weak acceleration, slow speed increase, and a jerking sensation. 4. Ignition system issues: If the spark plugs are heavily carbonized and misfiring, it can also affect engine acceleration. 5. Throttle body, fuel injectors, and intake manifold: Excessive carbon buildup in the throttle body, fuel injectors, or intake manifold can cause jerking. Regular carbon cleaning is recommended.

Why Does the Engine Buzz at 100 km/h on the Highway?

Here are the reasons why the engine buzzes at 100 km/h on the highway: 1. Engine knocking: It is a sound similar to metal knocking, also known as cylinder knocking. The causes of the fault can be divided into three types: unqualified fuel, using inferior fuel or fuel with an excessively low octane rating; incorrect engine timing control, such as an excessively large ignition advance angle; excessive carbon deposits inside the engine. You can first try carbon cleaning through non-disassembly cleaning or high-speed driving. 2. Valve noise: After starting the engine, there is a "ticking" sound, which is the sound of the valves, especially when the engine is cold. This is because the oil pressure has not yet built up, and the valves are not properly lubricated. 3. Engine "backfire" fault: When the car decelerates and the throttle is released, there is a "popping" sound, which is the engine "backfire" fault, also known as engine "backfiring". Excessive carbon deposits on the valves or incorrect valve timing can cause abnormal noises. 4. Engine misfire: If one cylinder is not working, the engine will become unbalanced and produce abnormal noises, accompanied by severe engine shaking, insufficient power, and other faults. This may be due to faults in the ignition module, spark plugs, or fuel injectors, and the corresponding parts should be replaced.

What are the reasons why an EFI scooter won't start?

EFI scooter won't start for the following reasons: Poor sensor contact: Poor contact of the index signal sensor. Weak magnetic field or battery failure: Weak engine magnetic field or battery failure. Wiring issues: Problems with the ignition system wiring. Fuel supply issues: Poor fuel quality or engine failure. The troubleshooting methods for a scooter that won't start are as follows: Self-check the fuse: If there is no injector self-test sound, visually check if the fuse is blown and replace it if necessary. Check the index wire: Check the connection of the index wire and repair it. Check the signal: Check the strength of the magneto signal, etc.

What is the fuel consumption per kilometer for a 400cc motorcycle?

Generally, a 400cc displacement motorcycle consumes about 4-5L per 100 kilometers, which translates to approximately 0.04-0.05L per kilometer. However, if the motorcycle frequently travels on rough terrain, the fuel consumption may increase to about 5-6L per 100 kilometers, or 0.05-0.06L per kilometer. This is roughly equivalent to the fuel consumption of a car. To determine the fuel consumption per 100 kilometers for a specific motorcycle, you can fill up the fuel tank completely and record the mileage. Then, calculate the approximate fuel consumption range after all the fuel is used up. When refueling, you can also reset the odometer to zero and divide the amount of fuel added by the odometer reading to get the fuel consumption. If you want to improve fuel efficiency, it is recommended to avoid sudden acceleration or deceleration while riding and try to maintain a steady speed. This is the most fuel-efficient way to ride. Additionally, regular maintenance is essential to keep the motorcycle in good condition.
