In automobiles, MPI refers to Multi-Point Injection system, also known as Multi-Point Fuel Injection or Sequential Fuel Injection or Individual Fuel Injection, as opposed to Single-Point Injection. Principle of Multi-Point Injection system: The Multi-Point Injection system is equipped with an injector at the intake port of each cylinder, controlled by an electronic control unit for individual cylinder injection or group injection. Gasoline is directly injected into the intake front of each cylinder and then enters the cylinder with air to form a mixture. Function of Multi-Point Injection system: It avoids uneven air distribution and power loss caused by overlapping intake of adjacent cylinders; it precisely controls the fuel injection quantity and timing according to the timing. The forms of Multi-Point Fuel Injection include simultaneous injection, group injection, and sequential injection.

Which is on, off or on?

ON means on, and OFF means off. ON and OFF are very common buttons, not only in cars, but also in many daily-use appliances. Here is some relevant information: 1. SEL and OK buttons: The SEL button is a menu selection confirmation button, usually found on the multifunction steering wheel. The OK button has the same function as the SEL button, but some cars use SEL while others use OK. 2. A/C button: The A/C button is the compressor switch, the full name is Air-Condition, which is the air conditioning cooling switch, because the car air conditioning does not use the compressor when heating. 3. VOL+/- buttons: The VOL+/- buttons are used to adjust the volume up and down. VOL is the abbreviation of the word "volume", which means volume and can adjust the volume of the car audio.

When should fuel additive be added?

Add before refueling. This allows the fuel additive to fully mix with the gasoline under the impact of subsequent gasoline injection, achieving optimal usage results. Additional Information: 1. Fuel additives are primarily composed of nano-molecules, cleaning activators, antioxidants, anti-corrosion agents, demulsifiers, and over ten other components. They are specifically designed to target harmful substances in fuel such as sulfur, gum deposits, and engine carbon buildup, thereby enhancing power, promoting combustion, providing anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubrication effects. 2. The main function of fuel additives is to clean carbon deposits, which has always been their key selling point. Additionally, they help maintain the engine and fuel system. Certain specialized fuel additives can also improve the fuel's anti-knock properties (octane rating).

How to Reset MINI Tire Pressure Warning?

MINI tire pressure warning can be cleared by performing a tire pressure reset. Here are relevant details about MINI tire pressure warning: 1. When the tire pressure warning appears, first check the tires to see if they are underinflated. 2. If there's a tire leak, repair or replace the tire first, then inflate it properly. 3. The vehicle's computer doesn't have default tire pressure values - it uses passive detection. If one tire's pressure differs significantly from others, it's considered underinflated. Another situation where tire slippage occurs may also trigger low pressure warnings. The warning simply indicates a tire pressure issue and will continue until reset. If tires are intact, inflate them first before resetting. 4. After confirming all issues are resolved, you can directly press the tire pressure monitoring reset button to complete the reset.

What does it mean when the door indicator light stays on?

The door indicator light staying on means that a door is not properly closed (locked). When any door (excluding the trunk door) is open, the door indicator light will illuminate. When all doors are properly closed, the door indicator light will automatically turn off. Before driving, please check if the door open indicator light is on. If a door is not properly closed while driving, it is very dangerous. More details are as follows: 1. Each door has a switch, which can be seen on the door frame. If all doors are confirmed to be closed but the light is still on, it indicates that one of the door switches is damaged. 2. You can open a door and manually press the switch to test each one, checking for any abnormal tactile feedback. Generally, a faulty switch is often caused by oxidation of the switch contacts, leading to poor contact.
