What's the difference between 1.2 and 1.5?

Can a motorcycle battery still be used after being left unused for a year?

Motorcycle batteries cannot be used after being left unused for a year. Avoid storing in a discharged state: A discharged state refers to when the battery is not recharged promptly after use. The longer the battery remains idle in a discharged state, the more severe the damage will be. When the battery is not in use, it should be charged once a month to extend its service life. Regular inspection is necessary: During use, if the electric bike's range suddenly drops by more than ten kilometers in a short period, it is highly likely that at least one battery in the pack has issues such as broken cells, softened plates, or shedding of active material from the plates, leading to a short circuit. In such cases, it is advisable to promptly visit a professional battery repair facility for inspection, repair, or replacement.

Why Is the Clutch of a Manual Transmission Car Stiff?

Manual transmission car clutch stiffness may be caused by clutch plate, clutch pressure plate, release bearing failure, or clutch master/slave cylinder malfunction. Clutch function: As the component directly connected to the engine in the automotive transmission system, it handles the engagement and disengagement of power and the transmission system. This ensures smooth vehicle starting, seamless gear shifting, and prevents transmission system overload. Friction clutch: Refers to a clutch that transmits torque through friction between driving and driven components. Widely used in modern vehicles. Hydraulic coupling: Refers to a clutch using fluid as transmission medium. Previously used in automatic transmissions, now rarely employed in automobiles. Electromagnetic clutch: Refers to a clutch operating through magnetic transmission, such as those used in air conditioning systems.

What speed should the engine run at 2000 RPM?

When the engine is at 2000 RPM, the vehicle speed can generally reach around 80 km/h. Of course, the engine speed and vehicle speed are not in a one-to-one correspondence, as it also depends on the current gear, which is the transmission ratio. For new cars, the engine speed should not exceed 3000 RPM: Both excessively low and high RPMs are detrimental to engine break-in. The break-in period is divided into the initial, middle, and final stages, which is the process of forming an oxide protective film on internal engine components. Therefore, the quality of the break-in period directly affects the engine's lifespan in the long run. Generally, the first 500 km is the initial break-in period: It is advisable to keep the speed below 80 km/h and the RPM below 2200. The tire break-in period is 300 km, and since new tires lack optimal friction, driving should be cautious during this time.

What Are the Reasons for Headlights Not Working?

There are several reasons why car headlights may not be working: Circuit Fault: Due to poor connections or looseness in the wiring. Fuse Tripping: The fuse in the circuit has tripped or burned out. Poor Contact in Light Switch: The bimetallic strip contacts in the light switch have poor contact or fail to close. Turn Signals: Turn signals are the most commonly used signal lights, activated when the vehicle needs to turn. They should be turned on approximately 30 to 100 meters before the turning point, not just when reaching the intersection, to avoid causing rear-end collisions by catching following vehicles off guard. Headlights: Headlights have two modes: high beam and low beam. Use low beam on roads with streetlights in urban areas, and high beam on roads without streetlights or when driving on highways. When meeting another vehicle, switch from high beam to low beam. Tail Lights (Brake Lights): When the brake lights illuminate, they signal to following vehicles that the car is braking, prompting them to slow down. Emergency Signal Lights (Hazard Lights): Used in emergency situations such as temporary parking due to vehicle malfunction or in poor visibility conditions. Hazard lights are crucial for driving safety and should be regularly checked to ensure they are functioning properly.
