Modified cars can be legally driven on the road if they comply with regulations. Detailed explanation on making modified cars legal for road use: Aftermarket parts should match the original wheel size (including J-value and ET-value). If new tires are installed, the diameter difference between the old and new tires should ideally be kept within 3%. Policies allow the installation of roof racks with a height not exceeding 30 cm. Side steps are generally categorized into fixed and electric retractable types, both of which can be modified. Parts that cannot be modified include: Powertrain, exhaust system, and spoiler modifications. Any modifications require filing with the authorities.

How to Deal with the Abnormal Noise in Nissan Sunny's Clutch?

The main causes and solutions for the abnormal noise in Sunny's clutch are as follows: 1. Coordination issue between the accelerator and clutch. Poor coordination between the accelerator and clutch will definitely cause abnormal noise, such as stepping hard on the accelerator in a semi-clutch state or incorrect gear shifting timing. This can be resolved through continuous practice and understanding the car's "habits." 2. Lack of lubrication in the clutch pedal spring or insufficient spring tension. Re-lubricate or replace the spring. 3. Failure of the clutch "three-piece set." If there is a "clicking" sound when pressing the clutch, and the noise disappears after releasing, it is likely a fault in the release bearing, which needs to be replaced. 4. Dirty oil inside the wet clutch. For automatic transmission vehicles with a wet clutch, dirty oil inside the clutch can also cause abnormal noise.

What does TC displayed in the car mean?

The appearance of TC in the car indicates that the Traction Control System is active. Here is some relevant information about the Traction Control System: 1. The Traction Control System, also known as the Track Control System or Anti-Slip Regulation System, is part of the vehicle's active safety systems. It is a slip control system adopted after ABS and serves as a further development and important supplement to ABS functionality. While the functionality of the Traction Control System is the same across different manufacturers, the names vary. For example: Mercedes-Benz calls it ASR, Toyota calls it TRC, BMW calls it DTC, and Cadillac calls it TCS. 2. TCS is the abbreviation for Traction Control System; ASR stands for Acceleration Slip Regulation. When braking on slippery surfaces, the wheels may skid, potentially causing loss of directional control. Similarly, during acceleration or rapid acceleration, the drive wheels may also skid, leading to dangerous loss of control on icy or other slippery surfaces. The Traction Control System is designed to address such issues.

What is the difference between automatic block and semi-automatic block?

The differences between automatic block and semi-automatic block are as follows: 1. Automatic block divides several block sections between two stations, while semi-automatic block takes the distance between two stations as one block section. 2. Automatic block sections are equipped with track circuits, while semi-automatic block only has short track circuits at both ends of the station. 3. The unlocking of automatic block sections is automatically performed by the train's track circuit, while semi-automatic block sections require the duty personnel to complete procedures before they can be opened. Information about automatic block and semi-automatic block is as follows: 1. Semi-automatic block: This type of block requires manual handling of block procedures. Trains depart based on the display of the departure signal, but after the train departs, the departure signal can automatically close, hence it is called semi-automatic block. 2. Automatic block: Based on the train operation and block section conditions, the signals can automatically change their display. Trains run according to the signal display, and this block method is completely automatic, hence it is called automatic block. Automatic block is a device that automatically completes block tasks for running trains.
