The 'bang' sound when starting the engine is caused by the meshing of the starter gear with the ring gear. Here are some precautions regarding the use of automobile engines: 1. Avoid driving in neutral: The engine itself has a fuel-cut function during deceleration, and driving in neutral is not conducive to fuel economy. 2. Pay attention when using the vehicle: If you notice oil on the ground, determine whether it indicates an engine oil leak and promptly communicate with the car 4S shop to eliminate potential safety hazards. 3. Do not turn off the engine immediately: For vehicles equipped with turbochargers, do not turn off the engine immediately after high-speed driving or climbing a slope. Let the engine idle for 10 minutes before shutting it off. Vehicles with turbochargers accumulate carbon deposits several times faster than naturally aspirated vehicles.

Is the Fuel Consumption Displayed on the Car Accurate?

The fuel consumption displayed on the dashboard is for reference only. Additional information is as follows: 1. Fuel Consumption: Fuel consumption refers to the fuel economy indicator when a car is driving at a constant speed on good road conditions. 2. Tips for Saving Fuel: When starting the car, simply turn the key without pressing the accelerator or preheating. While driving, shift from 1st gear to 2nd gear as early as possible; the longer the driving route, the lower the fuel consumption. Throughout the driving process, avoid pressing the accelerator all the way down; instead, maintain it at 50% to 70%. When encountering a red light, shift to neutral, release the accelerator and clutch to achieve zero consumption. In this state, the car runs on inertia without consuming a drop of gasoline. Before reaching a turn, release the accelerator or apply the brake to reduce speed and maintain a steady pace. When going uphill, the driver should maintain as fast a speed as possible until more than half of the slope is climbed, and when going downhill, release the accelerator to let the car coast naturally. Driving with the windows open at a speed of 100 km/h increases fuel consumption by 5%. Incorrect tire pressure leads to unnecessary fuel consumption, and overloading or improper car modifications also result in higher fuel consumption.

What are the types of vehicles?

Here is an introduction to the types of vehicles: 1. Passenger cars: Designed to carry 2~9 passengers (including the driver), primarily for private use. Passenger cars can be classified by engine displacement: Mini passenger cars -- engine displacement below 1L; Subcompact passenger cars -- engine displacement between 1.0~1.6L; Compact passenger cars -- engine displacement between 1.6~2.5L. 2. Buses: Designed to carry more than 9 passengers, mainly for public services. Depending on the service type, buses can be categorized into city buses, long-distance coaches, group buses, and sightseeing buses. 3. Trucks: Used for transporting various goods, with a cabin that can accommodate 2~6 passengers. Due to the diversity of cargo, trucks vary in load capacity and body structure, mainly divided into general-purpose trucks and specialized trucks. 4. Towing vehicles: Primarily used for towing trailers, which can be classified into semi-trailer towing vehicles and full-trailer towing vehicles. Semi-trailer towing vehicles are equipped with a fifth wheel coupling at the rear to tow and support the front of the semi-trailer. Full-trailer towing vehicles come with their own cargo body, resembling trucks in appearance but with shorter length and wheelbase, and a tow hook at the rear. Towing vehicles are equipped with trailer braking systems and electrical connection panels for trailers.

Is an Annual Inspection Required for New Cars After Two Years?

New cars require an annual inspection after two years. According to Article 11 of the 'Opinions on Strengthening and Improving Motor Vehicle Inspection Work,' starting from September 1, 2014, non-commercial vehicles and other small and mini passenger vehicles within six years are exempt from inspection. However, exemption from inspection does not mean exemption from review. During the six-year exemption period, vehicle owners must still provide proof of compulsory traffic insurance and proof of payment or exemption from vehicle and vessel tax every two years, and directly apply for the inspection label from the traffic management department of the public security bureau. Notes for the annual inspection: 1. Car Wash: Wash the car before the annual inspection to keep the exterior clean. It's best to clean the engine area under the front hood to ensure that the staff can clearly see the engine number and chassis number. 2. No Car Stickers: Stickers on the front windshield can obstruct the driver's view, and large decorative stickers on the car body or dazzling club logos are considered unauthorized modifications of the vehicle's appearance and will not pass the annual inspection. 3. Regular Maintenance: Regular maintenance is also crucial. Many owners neglect maintenance, leading to excessive exhaust emissions.

What does the SVS indicator on the dashboard mean?

The SVS light in a car is similar to the engine malfunction indicator light. When the SVS light is on, it indicates that the engine control unit has detected an error signal from a certain sensor or that the sensor has exceeded its usage standard. When the ignition is turned on, the SVS light will illuminate for an automatic check and then turn off after a few seconds, allowing the vehicle to operate normally. Here are some related details: 1. Can the car still be driven if the SVS light stays on? You can try to start the engine. If it fails to start, it might be due to an abnormal fuel pump that cannot supply fuel properly to the engine. If the engine starts, it could be a fault with another sensor. In this case, the car can still be driven, but the fault may affect normal vehicle operation, such as increased fuel consumption or body shaking. 2. How to handle the SVS light being on: First, check if other car equipment shows any abnormalities, such as the coolant temperature gauge or oil pressure warning light. If only the SVS light is on and the engine can still start, drive cautiously, control your speed, and go to a repair shop for inspection as soon as possible. If symptoms like increased combustion chamber temperature or the oil pressure warning light appear, continuing to drive may lead to increased engine wear and early engine damage.

What Causes the Squeaking Noise from the Left Front Wheel of a Sedan?

The reasons for the squeaking noise from the left front wheel are as follows: 1. Severe brake pad wear: Normal brake pads are about 10mm thick. When the brake pads wear down to below 6mm, the vehicle may experience tire noise and weak braking. In this case, the brake pads need to be replaced. 2. Foreign objects on the brake disc: If sand, mud, or other foreign objects adhere to the brake disc, friction between them can cause noise. This situation only requires cleaning the brake disc. 3. Deformation of the left front wheel hub: If the car frequently travels on bumpy roads or high-speed sections with potholes, the strong impact can cause the front wheel to deform, leading to noise. For safety reasons, it is best to replace the wheel hub in this case. 4. Wear of the left front tire: Excessive wear of the left front tire or punctures from nails or stones can also cause noise. In this situation, further inspection at a repair shop is necessary. 5. Steering gear failure: If the steering gear malfunctions, it can also cause tire noise. In this case, a professional should be consulted for inspection.
