What is the general density of gasoline?

Gasoline generally has a density of 0.70 to 0.78g/cm³. Introduction to Gasoline: It is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, and can be used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C. The main components are C5-C12 aliphatic hydrocarbons and naphthenes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance). Characteristics of Gasoline: Stability: The ability of gasoline to resist oxidation under normal temperature and liquid phase conditions is called the oxidation stability of gasoline, referred to as stability. The indicators for evaluating gasoline stability include iodine value, actual gum, and induction period.

How to Use Transmission Fluid Correctly?

Transmission fluid primarily functions to maintain the cleanliness of the gear system and provides lubrication and longevity to the transmission components. The correct methods for using transmission fluid are as follows: 1. Generally, the automatic transmission fluid (ATF) in a car should be replaced every two years or every 40,000 kilometers. However, this varies depending on the vehicle model. For Japanese models, it is recommended to replace the fluid every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. 2. If the oil pan is removed for fluid replacement, up to 70% of the fluid can be replaced to ensure the transmission's health. Currently, the preferred method is dynamic fluid replacement, which uses specialized transmission cleaning equipment to fully circulate and drain the old fluid before adding new fluid, achieving a replacement rate of over 90%.

Is it mandatory for cars to be equipped with fire extinguishers?

It is not mandatory for cars to be equipped with fire extinguishers. According to relevant regulations: medium-sized and above passenger vehicles, as well as hazardous goods transport vehicles, should be equipped with fire extinguishers and fire-fighting equipment that are within their validity period. Failure to comply will result in a warning or corresponding fines. Although there are no strict requirements for private cars to have fire extinguishers, during the annual vehicle inspection, a fire extinguisher must be present in the car; otherwise, the inspection will not be passed. Cars can use dry powder fire extinguishers or water-based fire extinguishers. Dry powder fire extinguishers are quick and effective in extinguishing fires, and they are also inexpensive and widely applicable. Water-based fire extinguishers are further divided into water-based clean water fire extinguishers, water-based foam fire extinguishers, and water-based mist fire extinguishers, which are characterized by being dust-free, anti-suffocation, effective in fire extinguishing, and non-toxic and environmentally friendly.

Why is there a strong gasoline smell outside the car when starting it?

The reasons for a strong gasoline smell outside the car after starting it are as follows: 1. Fuel tank leakage: Sometimes when starting the car in winter, a very strong gasoline smell may occur, which could be due to a leak in the car's fuel tank or fuel line. 2. Piston carbon deposits: Excessive carbon deposits on the pistons caused by cylinder combustion. In fact, the cylinder has a certain adsorption effect on gasoline, but too much carbon deposits will cause a lot of gasoline to adhere to the valves and pistons, leading to insufficient high pressure in the car, which increases fuel consumption and also produces a stronger gasoline smell. 3. Incomplete gasoline combustion: Incomplete gasoline combustion can also produce carbon deposits, which will adhere to the valves. Under high pressure, incomplete combustion will lead to increased vehicle fuel consumption, and at this time, a strong gasoline smell can also be detected in the car.

How to Adjust the Ignition Timing Angle?

Automobile ignition timing angle can be adjusted using a vacuum gauge. During adjustment, it is necessary to refer to the data of the highest vacuum value when the car engine is in idle state, and align the fuel supply point with the high-pressure pipe oil outlet according to the scale. The ignition timing angle is a parameter that affects the working performance of the car engine by the ignition timing when the engine is operating. Relevant information about automobile ignition timing is as follows: 1. Automobile ignition timing refers to the spark plug sparking before the piston reaches the compression top dead center, igniting the combustible mixture in the combustion chamber. The angle through which the crankshaft rotates from the moment of ignition until the piston reaches the compression top dead center is called the ignition timing angle. 2. The ignition timing angle that reflects the best power and economy of the car engine is the optimal ignition timing angle, which is a very important parameter for the car.
