How to Open the Fuel Tank of 812 Superfast?

How many kilometers can you drive with a broken oil pump?

It is best to repair a broken oil pump promptly. The following is a related introduction to the oil pump: 1. Working principle: The oil pressure relief valve consists of a valve or ball and a coil spring. After the oil is sucked in through the filter screen, it is sent to the oil filter. When the oil supply pressure increases with the engine speed, the relief valve opens. At this time, the oil enters the inlet side from the outlet side via a bypass to maintain the specified pressure. Since the spring stiffness value used on the relief valve is very precise, the maximum pressure of the oil pump can be guaranteed. If the stiffness of the spring increases, the oil pressure will also increase. However, the discharge volume of the pump will not increase. 2. Influencing factors: Other factors that affect engine oil pressure include: the speed of the oil pump, as oil pressure increases with speed; the viscosity of the oil, as higher viscosity leads to higher oil pressure; and the oil clearance, as bearing gaps can hinder the oil pump from building pressure. When bearings are worn, it becomes difficult to form adequate pressure.

What Does the Exclamation Mark in the Car Mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or fault in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates a general performance, component, or functional fault in the car. Common issues include parking sensor faults, fuel cutoff system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, indicating a fault in the brake system or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a fault in the car lights. Solution: Visit a 4S shop for inspection as soon as possible or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the fault lights displayed on the dashboard are divided into two colors—yellow and red—for different levels of alerts: Yellow indicates a fault in the corresponding system, but the issue is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and call for professional assistance to prevent unforeseen dangers to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of safety hazards.

Which Wheels Are the Drive Wheels on a Car?

In ordinary cars, generally only the two rear wheels are drive wheels, with the two front wheels being driven wheels, or the two front wheels are drive wheels, and the two rear wheels are driven wheels. However, in off-road vehicles and full-time four-wheel-drive vehicles, all wheels are drive wheels. The drive configuration of a car mainly refers to the number and position of the drive wheels. Based on this fundamental standard, the method of using front wheels to drive the vehicle is called front-wheel drive (FWD), while using rear wheels to drive the vehicle is called rear-wheel drive (RWD), both of which belong to the two-wheel-drive configuration. Here is an introduction to car drive configurations by layout: 1. Front-engine, front-wheel drive (FF): This is the most common configuration for family cars, where the engine is placed in front of the front axle, and the front wheels are used for driving. Currently, most family cars adopt this drive configuration, with the engine and transmission mounted transversely in the engine bay, transmitting power directly to the front wheels through two half-shafts. 2. Front-engine, rear-wheel drive (FR): The engine is placed in front of the front axle. Under this layout, the engine and transmission can be arranged in two ways: transversely or longitudinally. Both arrangements require a driveshaft to drive the rear wheels. Vehicles with this drive configuration have the front wheels responsible for steering, while the rear wheels handle driving. 3. Mid-engine, rear-wheel drive (MR): In this layout, the engine is placed between the front and rear axles, and the rear wheels are driven via a driveshaft. This can be further divided into front-mid and rear-mid configurations. The engine placed between the front axle and the passenger compartment is called front-mid, while the engine placed between the passenger compartment and the rear axle is called rear-mid. 4. Rear-engine, rear-wheel drive (RR): As the name suggests, the engine is placed behind the rear axle, with the main weight concentrated on the rear wheels, opposite to the front-engine, front-wheel-drive configuration. Nowadays, few family cars use this layout, and it is more commonly found in public transportation vehicles.

Why does the fuel level drop so quickly after refueling?

First of all, don't rely too much on the fuel gauge as it's not very accurate. Some car owners have driven more than 80 kilometers even after the fuel light came on. If you're still concerned, you can check the fuel pump yourself, as it might be malfunctioning. Here are some precautions for refueling your car: 1. Refuel in the morning or evening: Gasoline is charged by volume rather than weight, and it expands with heat and contracts with cold. Refueling in the morning or evening when temperatures are relatively lower means the same volume of gasoline can have a higher mass, saving you money. Even with a 15-degree temperature difference between morning and evening, there's a difference of 0.62L. Even if it's not much, the risk of danger is lower at lower temperatures. 2. Don't fill the tank completely: When driving in the city, there's no need to fill the tank completely because city driving involves frequent stops and starts. A full tank increases the engine's load. It's best not to exceed two-thirds full. Overfilling can cause gasoline to overflow, which may flow into the intake manifold and "drown" the spark plugs, causing the engine to stall immediately after refueling. In severe cases, the car may not start normally, and gasoline might even leak from the carbon canister, which is very dangerous if exposed to open flames. 3. Don't wait until the tank is empty: The fuel pump in the tank relies on gasoline for cooling. If the gasoline level is too low and doesn't cover the pump, prolonged operation in this state may reduce the fuel pump's lifespan. This is less of an issue in winter but poses a higher risk in the hotter summer months. 4. Avoid refueling during thunderstorms: Try not to refuel your car during thunderstorms because the fuel nozzle may introduce stray currents into the fuel tank, increasing the movement of unstable gasoline molecules and creating potential fire or explosion hazards.

Is driving the wrong way in a roundabout always photographed or just captured?

Driving the wrong way is captured. Non-scene traffic violations mainly include dynamic and static violations. Driving the wrong way is a dynamic violation and is usually recorded through capture. Below is an introduction to violations: 1. Driving the wrong way on a one-way street: Generally, one-way road sections are equipped with surveillance cameras or electronic capture devices. Once a wrong-way violation occurs, the probability of being captured is very high, almost 100%. Of course, if you can promptly judge upon entering the wrong-way road that it is a one-way street and you are driving the wrong way, you should quickly make a U-turn in the correct direction without affecting other vehicles. This may help avoid being captured. 2. Relevant regulations: Motor vehicle drivers who violate prohibition signs or markings, fail to overtake or yield as required, or drive the wrong way will be penalized with 3 demerit points and a fine. If the wrong-way driving occurs on a highway, the penalty is an immediate 12 demerit points, a fine, and possibly a 12-month suspension of the driver's license.

What does horsepower mean?

The unit of horsepower is PS, commonly known as 'horsepower'. Horsepower is a commonly used unit of power measurement in engineering technology. It is a physical quantity that measures the maximum speed of a car. The higher the horsepower, the higher the maximum speed of the car. Physical description of horsepower: Once a car starts moving, it generates kinetic energy, which is physically described as: E=mv. The kinetic energy generated by the car is all produced by the engine. Therefore, the car's movement and acceleration require the engine to continuously perform work. Horsepower, which is the car's power, represents the speed at which the engine functions for the car. Under the condition that all other factors of a car are the same, the higher the horsepower of the car, the faster the increase in kinetic energy after the car starts moving. Introduction to horsepower: Horsepower is a major indicator of a car's performance. With the advent of the first industrial revolution, steam engines became widespread, and the steam era officially began. To demonstrate the power of steam engines, Watt compared them to horses. He found a horse and had it pull a pulley to calculate the power. The test result showed that within one minute, the horse could lift a bucket weighing one thousand pounds (approximately 907.2 kilograms) to a height of 33 feet (about 10 meters).
