Is 6L per 100km considered fuel-efficient on highways?

How Long Is the Break-in Period for a Car Generally?

During the break-in period of a new car, avoid sudden acceleration and braking. The engine speed should not exceed 3,000 rpm, and the speed on highways should not exceed 120 km/h. After running in the engine and transmission, the first oil change should be done at 5,000 kilometers to complete the break-in. Below are precautions for the break-in period of a new car: 1. Warm up before starting: This applies to fuel-injected cars. Before starting, turn the key to the second position and wait for 5-10 seconds before ignition. This is because the fuel pump starts working once the ignition is turned on, adjusting fuel pressure and injection volume. Therefore, waiting a few seconds before starting helps protect the new car's engine. 2. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. 3. Avoid overloading: Running a new car at full load during the break-in period can damage the components. Therefore, within the first 1,000 kilometers of driving, domestic cars should not exceed 75%-80% of the rated load capacity.

What is the difference between a steering wheel and a circle?

The difference between a steering wheel and a circle lies in the design of the bottom part: one is flat-bottomed, while the other is round. Advantages of a flat-bottom steering wheel: It can save space in racing cars as well as in family vehicles, effectively reducing the space occupied by the steering wheel. This is particularly beneficial for drivers with larger builds, who often need extra room to maneuver around the wheel. Due to its flat design, the flat-bottom steering wheel can be positioned closer to the legs, enhancing control. It also helps lower the vehicle's center of gravity, improving driving stability and safety. Advantages of a round steering wheel: It is more ergonomic, especially when turning the wheel back to center, providing a much better feel compared to a flat-bottom steering wheel. When turning the wheel more than a full rotation, the round design offers more obvious advantages, particularly during U-turns or sharp turns, ensuring smooth and effortless handling. It gives a sense of solidity and stability. There is no definitive superiority between round and flat-bottom steering wheels, nor are they indicators of a vehicle's quality. Most people do not have strong preferences regarding whether a steering wheel is round or flat-bottomed; the best choice is the one that suits the individual driver.

Methods to Determine the Condition of an Oil Pressure Sensor

Methods to determine the condition of an oil pressure sensor include observing the oil pressure indicator light, noticeable power loss, and reading fault codes with a diagnostic tool. Observing the oil pressure indicator light: If the oil pressure indicator light remains on after starting the vehicle, the engine should be shut off immediately and the vehicle should be sent for repair as soon as possible. Noticeable power loss: A faulty pressure sensor can lead to inadequate engine lubrication, increasing friction within the cylinders and resulting in reduced power output. Reading fault codes with a diagnostic tool: A specialized diagnostic tool can read the fault code "P01CA," which indicates that the oil pressure sensor voltage is above the upper limit. Causes of oil pressure sensor failure: Insufficient engine oil, dirty or viscous oil, thin oil or excessively high engine temperature, oil pipe leakage, improperly set bypass valve opening pressure, faulty oil pressure switch, pressure gauge or circuit issues, weak pressure relief valve spring, sticking, or damaged ball. Solutions for oil pressure sensor failure: Top up the engine oil, replace with higher-quality oil, inspect and repair the cooling system, oil pipes, and replace the pressure relief valve. There are two types of oil pressure sensors: bimetallic strip type and variable resistance type. When the ignition switch is turned to ON, current flows through the heating coil of the bimetallic strip 4, causing it to deform and separate the contacts. The strip then cools and straightens, closing the contacts again. This cycle repeats, creating a pulsed current in the circuit. When oil pressure is low, the sensor diaphragm 2 deforms less, resulting in lower contact pressure, shorter closing time, longer opening time, and lower frequency changes. This leads to a smaller average current in the circuit, less bending deformation of the bimetallic strip 11, and a smaller pointer deflection angle, indicating low oil pressure. Conversely, when oil pressure is high, the pointer deflection angle increases, indicating high oil pressure. When the base is under force, the resistance strain gauge changes, altering the resistance and thus the voltage across the resistor. However, since this resistance change is minimal, an amplifier is required to amplify the electrical signal. When oil pressure decreases, the resistance of sensor 5 increases, reducing the current in coil L1 and increasing the current in coil L2. The rotor 2 drives the pointer 3 to rotate counterclockwise with the resultant magnetic field, indicating low oil pressure. When oil pressure increases, the resistance of sensor 5 decreases, increasing the current in coil L1 and reducing the current in coil L2. The rotor 2 drives the pointer 3 to rotate clockwise with the resultant magnetic field, indicating high oil pressure.

Does the Dash Cam Continue Recording When the Car is Turned Off?

Normally, a dash cam cannot record when the car is turned off. If the dash cam has a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is limited. This is because the dash cam's power is supplied by the car, so it can only operate when the car is running. Some dash cams have built-in batteries, but the battery capacity is too small to support prolonged operation. Connecting the dash cam directly to the car battery can cause prolonged discharge, which may affect the battery's lifespan. A dash cam is a device that records video and audio information during vehicle operation. After installation, it can document the entire driving process, providing crucial evidence in case of traffic accidents. Parking monitoring functions in dash cams come in two types: one is continuous recording, and the other activates short-term recording only when the vehicle detects vibration. However, there are currently no dash cams capable of continuous long-term recording after the car is turned off. For parking monitoring to work, the dash cam must either have an embedded rechargeable battery or be connected to the fuse box (ACC power). After the vehicle is turned off, it automatically enters parking surveillance mode, where sensors continuously monitor the vehicle's status. If any abnormal activity or vibration is detected, the dash cam automatically records and stores the footage separately. Compared to constant power connection, dash cams with parking monitoring connected via the fuse box (ACC) are more energy-efficient and reduce harm to the car battery. However, if the vehicle remains unused for several days, the battery may still drain, making it difficult to start the car.
