What Causes the Engine to Stall Immediately After Starting?

Possible reasons for the engine stalling immediately after starting are as follows: 1. The vehicle's anti-theft system is triggered, locking the engine, which allows the engine to start but not run, while the anti-theft light is on. This situation generally occurs in Volkswagen and Audi models, mostly because the owner, to prevent key loss, privately made a key without a chip or the key was dropped, weakening the signal, making the system unable to recognize it. Or it may be due to the replacement of the engine computer or anti-theft system components without proper matching, or damaged wiring. 2. Ignition switch failure, where the ignition line has power when starting, but power is cut off when the key is released, causing sudden stalling. This is usually caused by poor contact of the internal contacts of the ignition switch, often accompanied by the dashboard battery light, oil light, and engine fault light not turning on. Some may intermittently experience faults such as no air conditioning or heating, headlights not working, or electric windows malfunctioning before the fault occurs.

How to Interpret the Size Corresponding to Car Inner Tube Models?

Automobile tire specification model parameters are expressed in millimeters for the section width and the percentage of the aspect ratio. Following these are: the tire type code, rim diameter (in inches), load index (code for allowable carrying mass), and allowable vehicle speed code. Here is an example to explain the meaning of the numbers and letters in a tire model: 225/60R17 99H. 1. 225: Represents the section width, simply understood as the width of the tire tread. 2. 60: Represents the aspect ratio, simply understood as the height of the tire sidewall. 3. R: Represents the tire type code, where R stands for radial tire. 4. 17: Represents the wheel diameter, indicating the tire is suitable for 17-inch wheels. 5. 99: Represents the tire's load index, indicating the maximum weight the tire can bear. 99 corresponds to a maximum load capacity of 775KG. 6. H: Represents the tire's speed rating, indicating the maximum speed the tire can withstand. H corresponds to a maximum speed of 210KM/H.

What are the length and width of a 60-inch suitcase in centimeters?

60-inch suitcase: Dimensions: 105cm*60cm*165cm. Introductions to suitcases of various sizes are as follows: 1. 20-inch suitcase: Recommended for one person on business trips or short trips lasting 1–5 days. Capacity is approximately 43 liters, with detailed dimensions of 50*36*28CM, capable of holding about 30–35 shirts. 2. 24-inch suitcase: Recommended for two people on domestic trips lasting 7–10 days. Capacity is approximately 60 liters, with detailed dimensions of 60*45*30CM, capable of holding about 50–60 shirts. 3. 26-inch suitcase: Recommended for two people on domestic trips lasting 7–10 days. Capacity is approximately 85 liters, with detailed dimensions of 66*46*30CM, capable of holding about 70–80 shirts. 4. 28-inch suitcase: Recommended for two or more people on overseas trips without shopping or for one person studying abroad for more than 10–15 days. Capacity is approximately 102 liters, with detailed dimensions of 70*50*35CM, capable of holding about 100–120 shirts.

What is the calorific value of gasoline?

Gasoline has a calorific value of approximately 10,490 kcal, which is equivalent to 4.6×107 J/kg. More relevant information is as follows: 1. Introduction to gasoline: Generally, at room temperature, the density of 92-octane gasoline is about 0.725 grams per milliliter, making one liter weigh 1.45 pounds. The density of 95-octane gasoline is about 0.737 grams per milliliter, so one liter weighs 1.474 pounds. The density of 98-octane gasoline is approximately 0.753 grams per milliliter, meaning one liter weighs 1.506 pounds. 2. Overview of gasoline: At room temperature, gasoline is a colorless to pale yellow, easily flowing liquid that is difficult to dissolve in water and highly flammable. Its distillation range is from 30°C to 220°C. When the concentration in air is between 74 to 123 grams per cubic meter, it can explode upon contact with fire. The calorific value of gasoline is approximately 44,000 kJ/kg (the calorific value of a fuel refers to the amount of heat produced when 1 kg of the fuel is completely burned).

Why does the battery get hot after adding distilled water?

The battery heating up after adding distilled water is due to the reaction between the generated oxygen and hydrogen from the electrolyzed water, which releases heat. Electrolyte requirements: The electrolyte must be prepared using chemically pure sulfuric acid (or specialized electrolyte) and distilled water. Industrial sulfuric acid and ordinary water, containing impurities such as iron and copper, can cause self-discharge and damage to the plates, and thus should not be used in batteries. The specific gravity of the electrolyte should not be less than 1.19. When adding the electrolyte, first add distilled water to near the minimum mark, then add pure sulfuric acid (or specialized electrolyte) to achieve a specific gravity of around 1.2. The amount of liquid added should not exceed the upper limit mark. Precautions during charging: During the charging process, when the voltage of a single cell in the battery rises to 2.4V, more bubbles will start to appear in the electrolyte. At this point, the charging current should be halved. After charging, a discharge test should be conducted to avoid situations where a sulfated and damaged battery appears to be charged on the surface but is actually unusable. Therefore, before charging, observe the battery for any sulfide sedimentation, and replace it if necessary.

Where is the tire pressure monitoring device installed?

Tire pressure monitoring devices are generally located at the tire valve stem or on the wheel hub. The tire pressure monitoring device automatically monitors tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure tire pressure. It transmits pressure information from inside the tire to a central receiver module via wireless transmitters, then displays the pressure data for each tire. The system automatically alerts when tire pressure is too low or if there is a leak. Indirect tire pressure monitoring: When a tire's pressure decreases, the vehicle's weight causes that wheel's rolling radius to become smaller, making it rotate faster than other wheels. By comparing the rotational speed differences between tires, it monitors tire pressure. The indirect tire alert system essentially relies on calculating the tire's rolling radius to monitor pressure. Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, along with a 4-wheel indirect system. Compared to using only direct systems, this hybrid system can reduce costs and overcome the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.
