Fuel consumption rate refers to the amount of fuel consumed by an engine working at one kilowatt of power for one hour, also known as the vehicle's brake-specific fuel consumption, often abbreviated as BSFC (Brake Specific Fuel Consumption); or it refers to the fuel consumption per unit of effective work per hour, usually expressed in fuel consumption per kilowatt-hour. Effective fuel consumption rate refers to the fuel consumption per unit of effective work, abbreviated as fuel consumption rate, measured in grams per horsepower-hour. It is a primary indicator for measuring the fuel economy of internal combustion engines. The fuel consumption rate for agricultural internal combustion engines is generally: diesel engines 170-220 (grams/horsepower-hour); gasoline engines 240-400 (grams/horsepower-hour). The fuel consumption rate of an engine can be divided into indicated fuel consumption rate and effective fuel consumption rate. The indicated fuel consumption rate refers to the fuel consumption per unit of indicated work, usually expressed in grams per kilowatt-hour of indicated power. The effective fuel consumption rate refers to the fuel consumption per unit of effective work, usually expressed in grams of fuel consumed per kilowatt-hour of effective work.

What Material is a Car Cover Made Of?

Car covers are made from materials such as PVC, single-coated fabric, double-coated flame-retardant fabric, nano flame-retardant fabric, PU material, and gold-pulled flame-retardant fabric. Car covers provide excellent protection for the vehicle's paint and windows. Regular use of a car cover can extend the lifespan of the paint, keeping it shiny and looking new. A car cover consists of three parts: the body, the buckle straps, and the spring hooks. Here is an introduction to the functions of car covers: Preventing Sun Exposure: They effectively protect against harmful dust settling into the car's interior and engine compartment, preventing sun damage that can age the interior and wear out mechanical components. Preventing Rainwater Corrosion: They effectively shield the car's surface from the acidic effects of rainwater and snow under urban pollution conditions. Preventing Excessive Interior Temperature: In summer, car covers can most effectively prevent the interior from overheating, protecting the upholstery from temperature-induced aging. Precautions for Using Car Covers: Do not cover the car immediately after turning off the engine. After the car is turned off, the system stops running, but the electronic water pump continues to cool critical areas like the turbocharger's intermediate bearing. Covering the car at this time is like putting a plastic sheet over a hot pot, leading to localized temperature increases and the formation of steam, which increases humidity. Before covering the car, ensure both the car body and the cover are clean. The inner layer of car covers is usually cotton-lined, providing some protection against minor scratches. However, if there are small particles like twigs or sand on the car body, the cover can act like sandpaper when blown by the wind, causing 360-degree "sanding" of the car's surface. When parking in areas with strict no-parking regulations, make sure the license plate is clearly and completely visible, or do not use a car cover. In such special zones, covering the car can easily be interpreted by traffic police as "intentional concealment of a motor vehicle's license plate," resulting in fines and penalty points.

Is It Necessary to Buy a Car If You Don't Drive Often?

For ordinary consumers, it is not necessary to buy a car because cars are meant to improve quality of life. If the car is not used frequently after purchase, then there is absolutely no need to buy one. Long-term non-use has significant impacts: When a vehicle is parked for a long time, the engine oil is prone to oxidation, which in severe cases may corrode mechanical parts; the car battery inevitably self-discharges when the vehicle is not started, leading not only to severe power loss over time but also shortening the battery's lifespan; prolonged parking can cause the vehicle's oil seals to age and leak; since tires are made of rubber, prolonged pressure on one spot can cause the part in contact with the ground to shrink and deform. If parked under poor conditions, tires are also prone to blowouts, posing a significant threat to travel safety. Vehicle depreciation: The longer the time, the higher the depreciation rate of the vehicle. Cars are consumables, and the vast majority of vehicles begin to depreciate from the first day they are driven.

What type of transmission oil should be used for the Corolla 1.2T?

Corolla 1.2T uses CVT transmission oil. Replacement frequency: Generally, it should be replaced every 80,000 to 100,000 kilometers. Criteria for replacing transmission oil: You can determine whether to change the transmission oil based on the operating condition of the vehicle's transmission. If the vehicle shifts smoothly and the transmission noise doesn't change significantly, you can continue driving without worry. However, if the vehicle feels sluggish when shifting, especially when the driving speed exceeds 100 km/h and the transmission noise increases noticeably, you should consider replacing the transmission oil. Replacing transmission oil is not actually difficult, but selecting, inspecting, and changing the transmission oil are the most critical steps. More than 80% of transmission failures are caused by deteriorated transmission oil. Therefore, timely inspection and replacement of transmission oil constitute proper transmission maintenance and can also extend the transmission's service life.

What gear should be used for climbing a slope with a Vios?

When climbing a slope with a Vios, generally shifting to D gear is sufficient. Climbing capability: The climbing capability of a car is evaluated by its maximum gradient, which refers to the maximum slope that a fully loaded car can overcome in first gear on a good road surface. Testing method for a car's maximum climbing gradient: Select a slope similar to the expected climbing gradient of the car, with a slope length greater than 25m and an 8-10m straight section before the slope. The test car should be parked on the straight section near the base of the slope, with the transmission set to the maximum traction output gear (usually first gear). After starting the car, press the accelerator pedal to the floor to climb the slope. If the car can successfully climb the slope, then select a steeper slope for testing until the car can no longer climb. The maximum slope that the car can climb is the maximum gradient it can overcome.

What to Do If You Accidentally Run a Red Light?

According to Article 2, Section 1, Clause 2 of the 'Scoring Standards for Road Traffic Safety Violations,' driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at a signal-controlled intersection or road section, crossing the stop line and continuing to drive. According to Article 26 of the 'Road Traffic Safety Law': Traffic signal lights consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. Article 44 states that motor vehicles passing through intersections must proceed in accordance with traffic signal lights, traffic signs, road markings, or the instructions of traffic police. Based on the following points, you can avoid running a red light: First, look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular indicator traffic lights. When arrow lights are present, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, you may turn right; when encountering an arrow signal light with a red right-turn arrow, you must not turn right, otherwise, you will be penalized for running a red light. Brake in time: When the red light turns on, do not let the front of your vehicle cross the stop line. If the front wheels accidentally cross and the rear wheels follow, the electronic camera will capture it, and you will be penalized for running a red light. If the front wheels have just crossed the stop line when the signal turns red, do not proceed through the intersection; wait for the green light before continuing. Check the green light countdown before proceeding: When the green light is flashing, if there is a countdown, use it to judge whether to proceed. If there is no countdown and your vehicle is close to the intersection with high speed, you may proceed to avoid running a red light due to delayed braking. If your speed is slow and you are far from the intersection, brake immediately to stop and avoid running a red light. Article 38 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China' states the following for motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signal lights, non-motor vehicles and pedestrians must follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If you are captured by surveillance cameras while yielding to such vehicles, manual review will not record the act of running a red light. Even if recorded, you can apply for reconsideration with the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights, the evidence of violation may be blurry, and the traffic police will not penalize you for mistakenly running a red light. Emergency situations: When transporting a critically ill patient to the hospital, you may run multiple red lights, and 12 points may not be enough. After delivering the patient, provide proof from the hospital or the person being assisted to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, it is best to call an ambulance to avoid accidents caused by running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at major intersections. Drivers must follow the gestures of the traffic police.
