How to Use the Gears of a BMW Automatic Transmission Car?

Can the Car Optimization King Really Save Fuel?

No, the effect is very minimal. Automotive Fuel: Fuel generally refers to substances that can convert their stored chemical energy into thermal energy through chemical reactions (combustion). Currently, the primary fuels used in automobiles are gasoline and diesel. With the increasing number of vehicles year by year, the environmental pollution caused by vehicle emissions and the gradual depletion of petroleum resources cannot be ignored. As a result, various alternative fuels have been increasingly widely adopted. Conventional Automotive Fuels: Gasoline and diesel are the most commonly used fuels for automobiles today. Obtained through petroleum refining, gasoline and diesel have high energy density, low cost, resistance to deterioration, and ease of transportation, making them highly suitable for spark-ignition engines and compression-ignition engines.

Is the failure rate high for Subject 4?

Subject 4 has a relatively low failure rate because the questions are not very difficult. Below is relevant information: Subject 4: Also known as the Subject 4 theory test or driver theory test, it is part of the motor vehicle driver's license examination. After the implementation of "Order No. 139 of the Ministry of Public Security of the People's Republic of China," Subject 3 was divided into two parts: the road test and the addition of a safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Teaching materials: "Safe Driving Starts Here," compiled by the Ministry of Transport of the People's Republic of China. Driving schools can uniformly purchase and distribute study materials, or students can purchase them at their own expense.

How Far Can a Car Go After the Fuel Gauge Reaches the Red Line?

When the fuel gauge needle reaches the red line, the car's fuel tank typically has about 10% of fuel remaining, allowing it to travel an average of 20-60 kilometers further. Here is some relevant information about the car fuel gauge: When the fuel gauge indicator light comes on: When the gasoline fuel gauge indicator light comes on and reaches the red zone, there is usually 15%~20% of the total fuel capacity remaining. The distance you can travel depends on calculations. If the fuel gauge light comes on while driving on a highway, there is no need to worry, as highway service areas are generally spaced about 40 kilometers apart, with a maximum distance of no more than 60 kilometers. How to handle the fuel gauge indicator light coming on: After the fuel gauge light comes on, even a compact car can continue driving to the next service area for refueling. If the distance is too long, you can reduce your speed and stay in the middle lanes to maintain an economical speed, which will further reduce fuel consumption. In case of a service area being closed, you can exit the highway at the nearest exit, where gas stations are usually located within about one kilometer of the entrance. Maintain a steady speed, avoid sudden braking, and do not drive too slowly, as low speeds also consume fuel. Control your speed and drive smoothly. According to tests, for low-displacement cars (1.3-1.8L), the most fuel-efficient speed is between 45-65 km/h, while for cars with 2.0-3.0L engines, the most fuel-efficient speed is between 55-75 km/h. Turn off all electrical devices in the car, such as navigation, radio, music, and air conditioning. Close the windows to reduce wind resistance, which can help save fuel.

What is the reason for the inconsistency between the two needles on the air pressure gauge?

It may be due to damage in one of the two circuits. Below is the relevant introduction: Automotive air pressure gauge: An air pressure gauge is an instrument used to measure air pressure, with various classifications. Among them, a tire pressure gauge is a type of air pressure gauge specifically for tires. It consists of a gauge head, piston, gauge body, scale, main spring, etc. The gauge head has only one pressure measurement port, featuring a simple structure, small range, high accuracy, and ease of use, making it suitable for measuring tire pressure on small vehicles such as micro cars and motorcycles. Working principle: Inside the main tube of the tire pressure gauge, there is a well-sealed piston, and the interior of the tube is very smooth. The piston is located at one end of the tube, and the plug is at the other end. A compression spring connects the piston and the plug, used to push the piston toward the left side of the tube.

How many pages does a vehicle license have?

A vehicle license consists of 2 pages in total, with the second page being the duplicate copy. The duplicate copy is referred to as the "supplemental page" and is used by the police to record relevant information and data. Below is related information: Driving License: The full name of the driving license is the Motor Vehicle Driving License, also known as a "driver's license," which is the required certification for legally operating motor vehicles. Application Location: Applicants residing in their registered permanent residence should apply at their registered location. Applicants residing temporarily can apply at their temporary residence location (in Ningbo, a temporary residence permit valid for at least 3 months is required for application). Active military personnel (including armed police) should apply at their stationed location. Foreign nationals should apply at their place of residence. For applying to add additional permitted vehicle types, the application should be submitted at the location where the current motor vehicle driving license was issued.
