What is the speed of urban buses?

Urban buses typically travel at speeds between 25 to 50 kilometers per hour, not exceeding 60 kilometers per hour, but can reach up to 80 kilometers per hour in suburban areas. Here are specific details about buses: Large-scale transportation: Buses are the most common form of mass transit. Increasing demand: The development of urbanization and motorization has led to continuous growth in urban population and areas, resulting in a corresponding rapid increase in the demand for public transportation, which requires public transport companies to deploy more buses. According to statistics of 0.6 buses per 10,000 urban residents, the existing urban bus fleet is approximately 264,000 vehicles. By 2010, this number needed to reach at least 630,000, with an average annual increase of 3 to 4 thousand buses, plus replacements for scrapped buses, totaling an average annual increase of 55,000 buses. Purpose: Buses serve as a means of transportation for the general public to commute to and from work, offering affordability.

How often should a 5-seater SUV undergo inspection?

5-seater SUVs are categorized into commercial and non-commercial use. For commercial passenger vehicles, inspections are required once a year within the first 5 years, and every 6 months after exceeding 5 years. Small and micro non-commercial passenger vehicles are exempt from annual inspections within the first 6 years, require inspection once a year after exceeding 6 years, and every 6 months after exceeding 15 years. A 5-seater SUV falls under the small passenger vehicle category. Annual inspection, also known as annual review, refers to the safety inspection conducted every year or every two years, covering comprehensive checks including the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, etc. Annual inspection usually refers to the examination of certain formal IC cards, while annual review is more commonly used in daily life.

How to Solve the Problem of the Starter Motor Not Turning When the Engine is Hot?

Solutions for the starter motor not turning when the engine is hot: 1. Wait for the engine to cool down and restart. If the motor turns normally, it indicates an issue with the electromagnetic switch, which should be replaced; 2. Check if the battery is low on power. If the battery is in good condition, inspect the starting circuit. If the circuit is also intact, the problem lies with the motor, which should be replaced directly; 3. Examine the coolant temperature sensor and intake air temperature sensor. If their resistance values do not meet the standard, they should be replaced immediately. The motor, also known as the starter, is an electric motor or engine that operates by the force exerted on an electrified coil in a magnetic field, causing the starter rotor to rotate. The small gear on the rotor drives the engine flywheel to rotate, which is the working principle of the motor, also referred to as the starter.

Does High RPM in Low Gear Damage the Car?

High RPM in low gear can severely damage the car, leading to wasted gasoline, engine damage, and excessive carbon buildup. Wasted Gasoline: The biggest impact of driving at high speed in low gear is increased fuel consumption. When driving in low gear, the faster the speed, the higher the engine RPM, resulting in relatively higher fuel consumption. The increase in fuel consumption varies depending on the vehicle model and gear, but generally, high RPM in low gear can increase fuel consumption by 2 to 3 times, with a difference of up to 12 milliliters compared to normal driving. Engine Damage: Failing to fully utilize the car's kinetic energy forces the engine to operate at high RPM. Since the gearbox is in low gear, suddenly shifting the car into high RPM operation will cause the engine to be driven by the car's movement, leading to noticeable changes in sound, which is not advisable during operation. Excessive Carbon Buildup: Long-term high RPM in low gear can cause significant carbon buildup due to incomplete fuel combustion and poor oil sealing under high temperatures. These conditions contribute to carbon deposits. When carbon buildup reaches a certain level, it can lead to difficulties in starting the vehicle, increased fuel consumption, reduced engine power, and sluggish acceleration.

What Type of Oil Should Be Changed During the First Car Maintenance?

During the first car maintenance, the type of oil to be changed primarily depends on the engine type: 1. For naturally aspirated engines, synthetic or full synthetic oil is recommended; 2. For turbocharged engines, full synthetic oil is recommended. Engine oil, also known as engine lubricant, plays crucial roles in the engine, including lubrication, cleaning, cooling, sealing, reducing wear, damping vibrations, and preventing rust and corrosion. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. The purpose of car maintenance is to eliminate potential hazards, prevent faults, and extend the service life.
