Motorcycle 400cc refers to a displacement of 0.4 liters. Displacement is the total volume of all engine cylinders from top dead center to bottom dead center. The size of displacement affects engine power and fuel consumption. Under normal circumstances, engines with larger displacements have stronger power. Motorcycles are gasoline-powered two-wheeled or three-wheeled vehicles steered by handlebars, known for their lightness, flexibility, and speed. They are widely used for patrol, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.

A 400cc displacement refers to the size of a motorcycle engine, meaning 400 cubic centimeters. This falls into the medium displacement category, sitting between small displacements like 125cc and super-large displacements like 1000cc. When I ride a 400cc bike, I find it exceptionally balanced—it has enough power without being too aggressive. Many people recommend 400cc for beginners learning to ride because it accelerates smoothly and is super convenient for city commuting. It's also fuel-efficient, consuming around 3 to 4 liters per 100 kilometers in urban riding, which is much more economical than larger displacements. Maintenance is straightforward, with parts being easy to find, so you don’t have to worry about it being too troublesome. Overall, a 400cc bike is a versatile choice—great for daily commutes and perfect for weekend joyrides.

What are the reasons for the reversing camera turning black and white?

The reasons for the reversing camera turning black and white are as follows: 1. Vehicle computer crash: Nowadays, vehicles have many electronic components, especially with the continuous updates and iterations of car connectivity systems. Many vehicles have complex multimedia systems, leading to an increased likelihood of dashboard screen malfunctions. You can try turning off and restarting the vehicle and the onboard computer to see if the screen display can be restored. If repeated attempts fail to resolve the issue, it is necessary to visit a 4S store for inspection, refreshing, or repair of the relevant module. 2. Loose or detached wiring clips: Many wiring connections are made through direct plug-in clips. When encountering bumpy roads or due to original installation quality issues, clips may become loose or detached, causing the dashboard screen to malfunction. This can only be resolved by visiting a 4S store or repair shop to open the back of the screen and reinsert the clips tightly. 3. Failure of the car multimedia module: This situation is relatively common. Sometimes, due to the abundance of electronic products in the car, the content displayed on the large screen becomes too much, leading to interference between internal modules. This can easily cause issues with the car multimedia system. Repeated restarts may not help, and the only solutions are to restore factory settings or visit a 4S store for a software refresh.

How Long Does the First Car Inspection Take?

Car first inspection takes one to two hours. The content includes replacing engine oil, brake fluid, clutch fluid, air filter, air conditioning filter, etc. The purpose of the first car inspection: It is to identify factors that affect product quality during the production process as early as possible. Engine oil and oil filter need to be replaced because, due to poor air quality and harsh environments, both the engine oil and oil filter must be replaced during the first inspection to extend the engine's service life. Precautions for the first car inspection: The first car inspection only requires checking easily worn parts such as engine oil, oil filter, tires, and lights. Before the inspection, prepare the necessary materials: the handler's ID card, the car's valid compulsory traffic insurance policy (a copy, original, electronic policy, or transcript with the insurance company's red stamp within the validity period, which must include the vehicle and vessel tax), and the car's driving license. During each maintenance session, inspect the transmission. Although there is no need to replace the transmission oil, regularly check the transmission fluid level and avoid using non-original oil for replacement.

What's the Matter When There's a Gasoline Smell in the Car but No Oil Leak?

If there's a gasoline smell in the car but no oil leak, it could be a normal phenomenon, and the situation should be assessed case by case. When encountering this issue, ensure personal safety by parking the car and then inspect to identify the source of the gasoline smell. Poor sealing of the fuel tank cap: The rubber gasket needs to be replaced. Leakage at the gasoline pipe connection: Sometimes, there may be leakage at the connections of the gasoline pipes, allowing the gasoline smell to enter the car through the air conditioning system. Gasoline pipes generally do not leak, but if a leak occurs, the gasoline smell can enter the air conditioning system. If there is leakage at the connection point, over time, dust may accumulate on the surface, forming sludge. Residue during fuel pump installation or removal: Installing or removing the fuel pump must be done inside the car, and during this process, some residue may inevitably remain. If not cleaned properly, a gasoline smell may be noticeable during car use. Overfilling the fuel tank: If the fuel tank is overfilled, gasoline may flow into the carbon canister through the pipes. The carbon canister, originally designed to collect gasoline vapors, may release excess gasoline vapors through the vent holes when invaded by liquid gasoline. When the air conditioning is in the external circulation mode, the gasoline smell can enter the car.

What Causes Abnormal Noises from Car Tires?

Tire abnormal noises can be caused by nails or debris puncturing the tire, worn brake pads, uneven tire tread, or wheel bearing issues. Nails or debris in the tire: The noise occurs once per tire rotation, sounding like a "tap" or "click" hitting the ground, with the rhythm accelerating as speed increases. For debris, simply removing it may solve the issue. If it's a nail and tire pressure remains stable, you can drive directly to a repair shop for a patch in urban areas. Worn brake pads: Front brake pads usually have electronic wear indicators, while rear ones often use mechanical alarm tabs. When brake rotors become excessively thin, they produce a metallic "screeching" sound. The noise is faint when not braking but intensifies when braking becomes harsh. Immediate slow driving to replace pads is necessary. Brake pad thickness can often be checked through wheel rim gaps - replacement is critical when thickness falls below 3mm. Uneven tire tread: This manifests as a continuous "rumbling" noise, as if driving over obstacles, typically accompanied by steering wheel vibration and wandering. Tire replacement is recommended in such cases. Wheel bearing noise: This produces a "humming" sound that increases with speed. To identify the problematic bearing, lift the wheel and inspect following diagnostic procedures. Confirmed bearing issues require prompt workshop attention to prevent axle or body damage.

Where are the car turn signals located?

Car turn signals are located at the front and rear of the vehicle. Pushing the lever downward with the left hand activates the left turn signal, while pushing it upward activates the right turn signal. Function of car turn signals: Turn signals are the primary devices indicating a vehicle's dynamic information. Installed at the front and rear of the vehicle, they are activated when the car turns. They enhance driving safety by allowing others to anticipate the vehicle's movements and make correct judgments. Precautions for using car turn signals: Turn signals are categorized into contact-type flashers and non-contact-type flashers. If a contact-type turn signal malfunctions, the corresponding indicator light on the dashboard will flash continuously. Turn signals should be activated 10 to 20 seconds before making a turn to give following drivers sufficient reaction time. However, the exact timing may vary based on road conditions, traffic, and speed, but generally should not be less than 10 seconds. Use the left turn signal when entering a highway and the right turn signal when exiting, as entering involves a left turn and exiting involves a right turn. When merging onto a main road from an auxiliary road, use the left turn signal, and when moving from the main road to an auxiliary road, use the right turn signal.

What is the structure of a car?

The structure of a car consists of four basic parts: the engine, chassis, body, and electrical equipment. The engine of a car: The car engine is the device that provides power to the car, serving as its heart. It determines the car's power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems. The chassis of a car: It is composed of four parts: the transmission system, running gear, steering system, and braking system. The chassis supports and installs the car engine and its various components and assemblies, forming the overall shape of the car. It also receives the power from the engine to make the car move and ensures normal operation. The body: The main functions of the car body are to protect the driver and create a good aerodynamic environment. A good body not only enhances performance but also reflects the driver's personality. Car body structures are mainly divided into two types: body-on-frame and unibody. Electrical equipment: It can be summarized into three major components: the power supply system, control part (including circuits), and electrical devices. It consists of the battery, alternator, regulator, charging indicator, etc.
