How to Use BMW Cruise Control?

The following introduces the usage of BMW cruise control: 1. The BMW cruise control switch is located on the left side of the steering wheel, with a total of three buttons. The I/0 button is used to turn the cruise control on or off. 2. Press the I/0 button to activate the function, and the central control screen will display that the cruise system is ready. 3. When driving reaches the desired speed, press the "SET" button to set the vehicle at the current cruising speed, and release the accelerator pedal to achieve cruise control. 4. To adjust the speed, you can use the lever. Pushing it up is to accelerate; pushing it down is to decelerate. 5. Press the brake pedal or clutch pedal to cancel the cruise system. Press the "RES" button to restore the original speed. Press the I/0 button again to cancel the cruise control.

Why Can't a Motorcycle Engine Start?

Motorcycle engine failure to start can be caused by abnormal spark plug ignition, engine cylinder scoring, loss of magnetism in the motorcycle generator flywheel magnet, or poor contact between the ignition wire and the generator. When encountering difficulty starting or failure to start, it is essential to promptly troubleshoot to avoid unnecessary hazards. Abnormal Spark Plug Ignition: If the air gap between the magneto and the charging coil core is too large (the normal gap should not be less than 0.80mm), it can cause abnormalities when cutting the magnetic lines of force. Additionally, friction between the motorcycle flywheel and the charging coil core can cause a sharp rise in coil temperature, reducing insulation performance. Both scenarios can lead to abnormal ignition, potentially damaging the spark plug. Check if the spark plug has excessive carbon buildup and replace it promptly if necessary. Engine Cylinder Scoring: Cylinder scoring is a common issue during engine operation, leading to insufficient cylinder pressure, which prevents the motorcycle from starting normally or causes it to stall. After cylinder scoring occurs, professional repair is required, involving the replacement of critical components such as the cylinder liner, piston, and piston rings. Loss of Magnetism in Motorcycle Generator Flywheel Magnet: Most motorcycle engine generator magnetic fields consist of two or more sub-magnetic fields. However, when the magnet loses its magnetism, the magnetic field strength of each sub-field varies, resulting in asymmetric adjacent magnetic field strengths and significant current fluctuations. Professional repair shops should inspect and service the generator. Poor Contact Between Ignition Wire and Generator: Loose connections between the generator's output terminal and the ignition coil's input terminal can lead to poor contact, causing "jumpy" current fluctuations. Disordered current severely disrupts the spark plug's normal ignition function. Inspect whether the rubber sleeve connected to the ignition coil's secondary terminal and the protective sleeve of the terminal are sealed. Also, check for loose metal connectors inside. It is advisable to seek professional assistance.

What Causes the Abnormal Noise When Braking After Rain?

The reasons for abnormal noise when braking after rain: 1. Mismatch between brake pads and brake discs; 2. Fine sand carried by water adhering to the brake discs or rust on the brake discs after rain; 3. Brake pads worn to the limit; 4. Faulty brake system; 5. Missing or damaged fixing screws of the brake discs. In rainy conditions, brake discs can develop rust due to physical phenomena. When brake discs are rusty, a noticeable noise can be heard during braking. Almost all vehicles in the industry using cast iron brake discs experience this phenomenon, but it does not affect braking performance. The friction blocks have a certain rust removal capability. When the vehicle is parked for a while and the rust on the brake discs is minimal, after driving a certain distance and applying the brakes a few times, the rust on the brake discs will be removed, and the abnormal braking noise will disappear.

Why does the throttle of Changyong 1115 fluctuate?

The fluctuating throttle in Changyong 1115 could be due to a clogged fuel line. How to handle unstable motorcycle throttle: Check for blockages in the air filter and carburetor, ensure the fuel line is unobstructed, verify if the carburetor's air-fuel mixture is incorrect, inspect for air leaks in the intake pipe or valves, and examine the spark plug and ignition system components along with their wiring for any issues causing misfires. Also, check if the choke is closed, whether the carburetor needs cleaning, and if the fuel delivery system requires servicing. The importance of motorcycle throttle control: During startup; Starting requires sufficient torque, which varies by vehicle type and displacement. Some bikes have low torque at low RPMs, requiring gradual clutch release while applying throttle, while others may have enough torque at idle to start without throttle input—here, clutch control is key. During deceleration; Braking isn't always necessary—smoothly rolling off the throttle while downshifting can effectively reduce speed, though emergency situations demand coordinated brake and throttle use. In corners; When entering a curve, the bike leans to counter centrifugal force, making balance precarious. Braking becomes a harsh control method here as it disrupts equilibrium, whereas throttle modulation offers superior speed control. Maintain throttle in the linear power/torque range for instant acceleration or deceleration readiness. During gear shifts; Gear changes are deeply linked to throttle response. Different gears require specific engine RPM ranges for immediate power delivery—all controlled via throttle. The shift moment creates engine no-load conditions where abrupt throttle input may cause RPM spikes, leading to post-shift power instability and jerking. Thus, execute throttle-off shifts with simultaneous throttle blips. Downshifts requiring smooth power maintenance need slightly higher RPMs for better acceleration.

When to Turn on the Position Lights While Driving?

Position lights should be turned on in the following situations while driving: during nighttime driving, driving at dusk, when visibility is poor during rain, and when visibility is low in foggy conditions. Position lights, also known as width markers, are lamps installed at the front and rear high points of the vehicle. They are primarily used during driving periods such as dusk or overcast days to indicate the vehicle's width and height, helping other vehicles judge their relative positions and size during encounters or overtaking. Typically, the color of position lights is white at the front and red at the rear. The types and functions of vehicle lights include: 1. Brake lights: to alert people or vehicles behind; 2. Turn signals: to notify surrounding vehicles and pedestrians; 3. License plate lights: to illuminate the vehicle's license plate at night; 4. High beams: to check the road conditions ahead at a distance.
