A car is generally composed of four major parts: the engine, chassis, body, and electrical equipment. Below is the relevant information: Engine: crankshaft connecting rod mechanism, valve train, fuel supply system, ignition system, lubrication system, cooling system, and starting system. Chassis: transmission system, running system, steering system, and braking system. The transmission system transmits the engine power to the driving wheels and consists of assemblies such as the clutch, transmission, universal transmission device, and main reducer. The running system is composed of the frame, steering axle, driving axle, suspension, wheels, etc. The steering system consists of the steering gear and steering mechanism. The braking system generally consists of two independent devices, namely the service braking system and the parking braking system. Body and electrical equipment: The body is used to accommodate the driver, passengers, and cargo. The electrical equipment consists of the power supply, ignition system, starting system, as well as the car lighting system, signal system, and instruments.

When I first started learning about cars, I found the knowledge a bit complicated, but gradually realized the basics are quite simple. It mainly covers a few areas: First, the powertrain—the engine is like the heart of the car, running on fuel or electricity; the transmission helps shift gears and affects acceleration smoothness. Second, the control components—the steering wheel changes direction, while the brake and accelerator pedals control speed. I remember my driving instructor always emphasized gently pressing them, not stomping suddenly. Third, safety features—seat belts must be fastened tightly, airbags deploy during collisions to protect you, and tire pressure monitoring reminds you to maintain safe pressure. Fourth, routine maintenance—I regularly check the levels of engine oil, coolant, and brake fluid, and inspect tire wear weekly to avoid alignment issues. Fifth, keeping up with the times—electric vehicles are spreading fast now, with similar basic operations but added charging knowledge. I started with books and friends' experiences—don’t fear mistakes, practice gradually, and you’ll get the hang of it. Remember one thing: no matter what car you drive, safety always comes first.

What Causes the Noise in the Steering Gear Rack and Pinion?

Noise in the steering gear rack and pinion may be caused by lack of lubrication, steering gear failure, insufficient tire pressure, and other reasons. Lack of Lubrication: If there is a lack of lubrication in the screws inside the steering wheel, it is necessary to remove the steering wheel cover and add lubricating oil inside. This should lubricate the tracks and shafts, resolving the issue. Steering Gear Failure: The steering gear may also malfunction. Normally, if the steering is turned too sharply during operation, it places a greater load on the steering gear, leading to severe wear and resulting noise. It is recommended to inspect and replace the faulty components. Insufficient Tire Pressure: Uneven tire pressure in the left front or right front tire can cause the front of the car to deviate, leading to unbalanced car bearings and misaligned steering gear, which in turn causes noise and deviation.

How many times can a vehicle be re-inspected if it fails the environmental protection test?

If a vehicle fails the environmental protection test, it can be re-inspected twice. Below is additional information regarding environmental protection inspections: Reasons for failing the environmental protection test: Use of low-quality fuel: Frequent use of poor-quality fuel can lead to excessive carbon buildup after combustion. It may also impair the performance of exhaust purification devices, reducing their lifespan and increasing pollutant emissions, resulting in failed tailpipe emission tests. Clogged or poisoned catalytic converter: If the vehicle is frequently driven at low speeds or uses inferior fuel, the catalytic converter may become clogged or poisoned, leading to malfunction. Precautions before the environmental protection test: You can purchase professional cleaning agents to remove and clean the catalytic converter, or drive at high speeds for a certain distance. High-speed driving helps clean the engine's fuel system and cylinders effectively. Therefore, before the annual inspection, it is advisable to fill up with high-quality gasoline and drive at high speeds before undergoing the test.

What is the reason for the AC light not working in Nissan Tiida's air conditioning?

Nissan Tiida's air conditioning AC light not working is due to the power fuse of the air conditioning switch being broken, which does not send a signal to the vehicle's compressor, naturally preventing it from cooling. Replacing the AC fuse located in the engine compartment's fuse box will resolve the issue. Function of the AC Button: The AC button is the switch for the air conditioning compressor. In summer, when using the air conditioning, the AC button must be turned on to activate the cold air. On the other hand, the warm air simply utilizes the internal heat circulation of the car and does not require the activation of the air conditioning compressor. Therefore, to use the warm air, you only need to adjust the air conditioning button without turning on the AC switch. Warm Air: The warm air comes from the heat generated by the engine during operation. When the engine's cooling system dissipates heat from the engine, the fan directs this heat into the car to create warm air. When the warm air is not in use, the fan stops, the heat vent closes, and the dissipated heat is completely released into the atmosphere.

What does it mean when the EPC light comes on in a vehicle?

Possible reasons for the EPC light to illuminate: The car's throttle is dirty and needs cleaning. Brake system malfunction, in which case the brake light may also not work. Fuel quality issues can trigger the EPC warning light. EPC (Electronic Power Control) stands for Engine Electronic Power Control System. When a sensor fails or detects abnormal conditions, the control system will take appropriate measures according to pre-set programs. Common causes of EPC light activation: Engine intake system failure, throttle malfunction, fuel system issues, Engine failure, ECU control unit problems, brake light failure. Solutions for EPC light illumination: Troubleshoot intake system issues, use qualified fuel, clean throttle body, etc. Remove carbon deposits from relevant components through cleaning. Re-flash related data (this applies when other solutions fail to resolve the issue). Other potential faults cannot be ruled out. Actual vehicle diagnostics should determine the exact cause before proceeding with repairs. When the EPC light comes on, follow these steps: Restart the vehicle after turning it off. If the EPC light doesn't reappear, it may indicate no serious problem - sometimes external interference can trigger it temporarily. If the EPC light frequently illuminates over time, first check whether brake lights are functioning. If brake lights don't work, inspect the brake switch, bulbs and wiring (sometimes a burnt-out brake bulb may be the cause - simply replacing it may solve the issue). If the EPC light persists after checking brake lights, visit an authorized service center for inspection. EPC indicator lights typically appear in two colors: yellow and red. A yellow EPC light means the vehicle can still be driven cautiously to a repair facility, while a red EPC light indicates serious problems requiring immediate parking and contacting professional technicians. Continued driving with a red EPC light may damage core components or compromise driving safety.

Can You Go Straight on a Left Arrow Green Light?

You cannot go straight on a left arrow green light. Classification of Traffic Signals: Traffic signals can be divided into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and railway crossing signals. Relevant Regulations on Signal Passage: Traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. Legal Liability Article 90: Motor vehicle drivers who violate road traffic safety laws and regulations regarding road passage shall be given a warning or fined. Where this law provides otherwise, punishment shall be imposed in accordance with the relevant provisions.

What to Look for in Urban Road Sign Recognition?

Urban road sign recognition generally refers to guide signs on ordinary roads. Guide signs for ordinary roads: Color and graphics: blue background with white graphics, white borders, and blue edging. Classified by function: route guidance signs, location guidance signs, roadside facility guidance signs, and other road information guidance signs. Principles for reading road signs: The general principles are: left for near, right for far; top for near, bottom for far. Route guidance signs are divided into: intersection advance signs, intersection notification signs, and confirmation signs. Intersection advance signs for ordinary roads are mainly used on highways. Due to the high density of urban road networks and short distances between intersections, such advance signs are rarely installed on urban roads. The layout and information selection for intersection notification signs are consistent with advance signs, with the only difference being that advance signs include distance information on the sign panel.
