What is the difference between turbocharging and supercharging?

Briefly describe the causes of low cylinder pressure

Briefly describe the causes of low cylinder pressure: 1. Air leakage between the cylinder head and the cylinder; 2. Air leakage between the spark plug sealing gasket and the cylinder head or air leakage from the pressure relief valve; 3. Air leakage from the crankcase; 4. Severe wear between the piston ring and the cylinder or piston ring sticking causing air leakage. The diagnostic methods for insufficient cylinder pressure are: 1. Unstable engine operation, popping sounds from the exhaust pipe or backfire in the carburetor; 2. Difficulty in cold start, with no significant change when climbing slopes; 3. Water droplets discharged from the exhaust pipe, backfire in the carburetor, or water leakage into or out of the crankcase. A cylinder refers to a cylindrical metal component that guides the piston to perform linear reciprocating motion inside the cylinder, which can be divided into: single-acting cylinders, double-acting cylinders, diaphragm cylinders, and impact cylinders.

Should You Turn Off the Engine Before Opening the Fuel Tank Cap When Refueling?

When refueling, you should turn off the engine before opening the fuel tank cap because the fuel tank contains a fuel pump, and opening the cap while the engine is running can create a hazardous situation due to exposure to external air. Therefore, it is essential to turn off the engine first. The automotive fuel tank, also known as the car fuel tank, operates on the following design principles: 1. Utilizing the heat generated by the engine during operation, a thermal circulation system is added between the engine, fuel tank, and radiator; 2. The original single fuel tank is redesigned into a combined fuel tank consisting of a main tank and an auxiliary tank; 3. A water heater is installed at the bottom of the fuel tank to use the engine's heat to warm the main tank; 4. The fuel supply pipe of the main tank and the oil pipe of the auxiliary tank are connected to the engine's fuel system through a fuel switching valve. The auxiliary tank is used when starting the car, and after driving 5 to 8 kilometers, the switching valve is activated to switch the fuel supply to the main tank.

If the dots are behind, it indicates the second half of the year, and you can subtract the number of dots from 13. 2. Numbers plus small dots and large dots: The numbers represent the year, the small dots represent the quarter (usually 4 small dots), and the large dots represent the corresponding month within the quarter (usually 3 large dots). 3. First line with numbers and small dots, second line with large dots and small dots: The numbers represent the production year of the glass, the small dots on the first line represent the month of that year (ranging from 1 to 12 dots), and the second line represents the corresponding days of the month, where large dots represent 10 days and small dots represent 1 day.
