Is it mandatory to merge motorcycle and car licenses?

Motorcycle and car licenses must be merged. Here is additional information: Relevant regulations: Article 46 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses' states that after passing the examination, applicants must receive no less than half an hour of education on traffic safety, civilized driving knowledge, and case studies of traffic accidents. Situations requiring license retrieval: The vehicle management office shall issue the motor vehicle driver's license on the day the applicant participates in the swearing-in ceremony. For those applying to increase the number of permitted driving vehicle types, the original motor vehicle driver's license must be retrieved. For those who are retired, demobilized, or resigned, the military or armed police motor vehicle driver's license must be retrieved. Requirements: Implemented according to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses' effective from April 1, 2016. Points for road traffic safety violations are deducted as 12 points, 6 points, 3 points, 2 points, and 1 point.

What causes unstable idling in the Corolla 1.2T?

Unstable idling in the Corolla 1.2T is primarily caused by severe carbon buildup in the engine. Reasons for engine carbon buildup: When excessive carbon deposits accumulate inside the engine, the gasoline injected by the cold-start fuel injector gets largely absorbed by the deposits. This results in an overly lean air-fuel mixture during cold starts, making ignition difficult. Under these conditions, the engine only starts easily after the carbon deposits become saturated with gasoline. Once started, the gasoline adsorbed on the carbon deposits gets drawn into the combustion chamber by the engine's vacuum suction, making the mixture too rich. This fluctuation between lean and rich air-fuel mixtures causes unstable idling after cold starts. Reasons for excessive carbon deposits in throttle body and intake tract: When excessive carbon deposits and dirt accumulate in the throttle body and surrounding intake passages, the cross-sectional area of the air passage changes. This prevents the control unit from precisely regulating idle air intake, resulting in either overly rich or lean mixtures that lead to abnormal combustion.

Can I deregister and scrap a motorcycle without bringing it in?

No, if a motorcycle has reached its scrapping age, it must undergo deregistration procedures. Otherwise, the owner cannot participate in the small passenger vehicle license plate lottery. Here are the relevant details: Timely deregistration procedures: According to regulations, if an individual has a motor vehicle (including a motorcycle) that should be scrapped but has not undergone deregistration procedures, that person cannot register a new vehicle and thus is ineligible for the small passenger vehicle license plate lottery. Natural disasters: For motor vehicles lost due to natural disasters, when processing deregistration, proof of vehicle loss issued by government departments at the township level or above is no longer required. Required materials: The vehicle owner must submit a written statement declaring the vehicle as lost, detailing the time and place of loss, and including a statement such as 'I confirm the truthfulness of the facts stated and am willing to bear corresponding legal and financial responsibilities.' After review by the traffic police department, the deregistration can be processed.

Reasons for Motorcycle Starter Squeaking and Not Starting

The most likely reason for a motorcycle starter making abnormal noises and not starting is a depleted battery, or corrosion on the battery terminals causing excessive resistance. Check if the starter relay is faulty, if the starter motor's coil is burnt out, if the starter motor itself is malfunctioning, or if the starter overrunning clutch is stuck. Below are additional details: Inspection Items: The electric start of a motorcycle consumes a significant amount of power, while the headlight and horn consume very little. Therefore, functioning lights and horn do not necessarily mean the battery has enough power for the electric start. Issues with the spark plug may require replacement. Sometimes, fuel can flood the spark plug—check if the spark plug tip is oily or wet, as this can also prevent ignition. Carburetor: If the carburetor is faulty due to prolonged use, it needs to be cleaned. In winter, cold weather can make it difficult to start the engine. In warmer southern climates, unless the motorcycle itself has a fault, starting issues are less common. In northeastern regions during early spring or late autumn when morning temperatures drop below 0°C, the engine oil may thicken, causing difficulty in starting.

What are the symptoms of a bad motorcycle bearing?

Symptoms of a bad motorcycle bearing include loud noises, increased risk of cylinder scoring, accelerated part wear, and a knocking sound when giving throttle. Here are some related details: Causes of damage: Repeated burning of main bearings and connecting rod bearings weakens the support at the burnt areas. Fractures often occur at the root of the connecting rod journal for cylinders 2 and 5 (taking a six-cylinder engine as an example), issues with main journal concentricity, and improper maintenance. There are many factors contributing to crankshaft damage, which involves high technical requirements. The crankshaft bears heavy loads within the engine, with fractures typically occurring between the main journal and connecting rod journal. Excessive clearance: Excessive clearance between adjacent main bearings, especially between the rear two and front two main bearings. Due to the relatively thin crank webs, the crankshaft is heavily loaded at both ends with the flywheel at the rear and the pulley at the front. The crankshaft also directly or indirectly drives other components like the camshaft. Additionally, uneven front and rear loads on the crankshaft, combined with individual cylinders not functioning, create inconsistent stress on the crankshaft, despite its potential to operate for millions of kilometers.

Reasons for the T-Roc's Central Control Screen Not Lighting Up?

Reasons for the T-Roc's central control screen not lighting up: It might be due to the power being turned off, there is a manual power button, or the power supply is disconnected. If these two reasons are ruled out, then connectivity and signal input issues should be checked. Poor line contact can cause the screen not to light up. Fuse failure, as well as issues within the car's multimedia system, could also be due to damage to certain modules. Solutions for the T-Roc's central control screen not lighting up: If the power is turned off or disconnected, the power should be restarted to check if it is powered on. For issues like poor line contact, fuse failure, or problems within the car's multimedia system, it is advisable to visit a 4S shop for repairs.
