Why can't the key be pulled out when the smart car is parked in P gear?

Is it okay for a new car to run continuously for four hours?

During the break-in period of a new car, it can be driven continuously for 4 hours, but the engine speed should not exceed 2000 rpm, and the speed should not exceed 80 km/h. Break-in process: The break-in mileage for a car is 1000–2500 kilometers, while imported cars generally have a longer break-in period, mostly 1500–3000 kilometers. The break-in period is divided into three stages. The initial break-in occurs within the first 100 kilometers, the preliminary break-in is achieved by 200 kilometers, and an oxide film forms by 3000 kilometers. Driving speed: During the break-in period, it is best to drive at low speeds. Generally, the maximum speed for a loaded truck should not exceed 45 km/h, while for passenger cars, the top speed should remain within 50–80 km/h.

What are the three functions of a flywheel?

Here is an introduction to the three functions of a flywheel: 1. Energy storage and speed stabilization: The flywheel utilizes its own moment of inertia to store part of the work input to the crankshaft during the power stroke, which is then used to overcome resistance in other strokes, driving the crank-link mechanism past the top and bottom dead centers, ensuring the crankshaft's rotational speed and output torque are as uniform as possible, and enabling the engine to overcome short-term overloads. 2. Driving component: It serves as the driving component of the friction clutch, engaging and disengaging with the clutch, transferring the engine's rotational force through the transmission to the drive wheels. 3. Flywheel ring gear: A flywheel ring gear is mounted on the outer edge of the flywheel, meshing with the starter's drive gear for starting the engine.

What is the approximate fuel consumption for a 3.5L displacement car?

3.5L displacement fuel consumption is 11-13L. Below are relevant introductions about fuel consumption: 1. Introduction: Generally refers to the gasoline consumption per 100 kilometers, which is a theoretical indicator for vehicles. 2. Methods to reduce fuel consumption: The longer the idling time when parked, the greater the fuel consumption, so minimize idling time; avoid rapid acceleration, slamming the gas pedal, and driving at low RPMs. 3. Factors affecting fuel consumption: Various working conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, all have an impact. 4. Calculation of fuel consumption: Fuel consumption per 100 kilometers = Volume of fuel (liters) ÷ Distance the car can travel with that amount of fuel (kilometers) × 100.

Can I Change a Spare Tire on the Highway Myself?

You can change a spare tire on the highway yourself, but you must move to the emergency stopping lane and set up a warning sign. Here are some precautions to take when changing a spare tire on the highway: 1. When parking: If your vehicle breaks down and you have to stop, immediately pull over to the right hard shoulder or emergency stopping lane, and turn on your hazard warning lights. If it's nighttime, don't forget to turn on your side marker lights and tail lights. 2. Setting up a warning sign: Set up a warning sign, commonly known as a triangle warning sign. It is usually stored in one of three places in the car: the trunk, the inside of the trunk lid, or under the trunk cover. Place the reflective side of the warning sign facing outward, walk in the direction of oncoming traffic, and place it 150 meters away in the corresponding lane. 3. Evacuation: Immediately move to the outside of the right guardrail and call the national highway emergency rescue number 12122 for assistance.

What are the penalties for driving in the wrong lane on highways?

Here are the penalties for driving in the wrong lane on highways: 1. Driving in the wrong lane on highways: If a motor vehicle is driven in the wrong lane on a highway, the penalty standard is: 3 demerit points and a fine. 2. Driving in the wrong lane on urban expressways: If a motor vehicle is driven in the wrong lane on an urban expressway, the penalty standard is: 3 demerit points and a fine. 3. Driving in the wrong lane on roads other than highways and urban expressways: If a motor vehicle is driven in the wrong lane on roads other than highways and urban expressways, the penalty standard is: no demerit points, but a fine. 4. Driving improperly on highways or expressways under low visibility weather conditions: According to new traffic regulations, driving improperly on highways or expressways under low visibility weather conditions results in a fine and 6 demerit points per violation. 5. Driving in the wrong guide lane: There are two scenarios: a) Driving in the wrong lane on highways or urban expressways results in 3 demerit points, a warning, or a fine; b) At intersections with traffic signals and marked guide lanes, driving in the wrong guide lane results in no demerit points but a warning or a fine.

Reasons for Shaking During Start-up of a 500-Kilometer Scooter?

Issues with the clutch system can also cause severe body shaking during the semi-engaged state at the moment of starting, leading to vibration in the brake pedal. There are two types of car accelerator pedals: suspended type and floor-mounted type. Here is some extended information: 1. Accelerator Pedal: The accelerator pedal is a control pedal that regulates car acceleration. Whether it's a left-hand drive or right-hand drive vehicle, it is installed on the right side and is best operated with the right foot. 2. Floor-Mounted Pedal: The pivot is located at the bottom of the pedal, allowing the entire foot to rest on it. The pedal itself acts as a fulcrum, making it easier for the calf and ankle to control the pedal, thereby improving precision in foot control and reducing fatigue. 3. Suspended Accelerator Pedal: The pivot is located at the top of the pedal bracket, and the lower structure is relatively simpler. This design makes the pedal lighter to operate, and the pedal bracket can be designed as an iron rod. This largely reduces costs, making it a preferred choice for manufacturers.
