What does it mean that gasoline cars cannot add diesel?

What it means that gasoline cars cannot add diesel is that gasoline cars should be fueled with gasoline, and diesel cars should be fueled with diesel—gasoline cars must not be fueled with diesel. The reasons why gasoline cars cannot add diesel are as follows: Gasoline has a low carbon content, while diesel has a relatively high carbon content, and their densities also differ significantly. The relationship is similar to that between light water and heavy water, with gasoline and diesel being analogous to light oil and heavy oil, respectively. Compared to gasoline, diesel has a lower ignition point and is less volatile, while gasoline has a higher ignition point and is more volatile. In a gasoline engine, when the fuel injector sprays gasoline and the air entering through the throttle valve forms a mixed gas that enters the cylinder, diesel may ignite before the spark plug fires, causing abnormal pressure in the combustion chamber and resulting in knocking. Additional information on the consequences of adding the wrong fuel: 1. The fuel injector pressure in gasoline engines is lower than that in diesel engines. When diesel is added, it cannot be fully atomized, leading to incomplete combustion, resulting in engine power loss, unresponsiveness to throttle input, and the emission of black smoke from the vehicle. 2. Diesel has a low ignition point and may combust violently on its own before the spark plug fires, causing abnormal pressure in the combustion chamber, commonly known as knocking, which poses significant safety hazards.

What Does the Yellow Exclamation Mark in the Car Mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard that feature an exclamation mark, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. Below is a detailed introduction to the exclamation mark fault lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Main issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a malfunction in the transmission or transmission lubricant being below the normal range. Transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire Pressure Abnormality: A horizontal line under parentheses with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a malfunction in the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. You can also check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the dashboard are divided into two different colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the corresponding repair point for maintenance to eliminate potential safety hazards in time. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and call for professional help to prevent unpredictable dangers to the vehicle and personal safety from forced driving. It should be noted that when the car is ignited and started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will automatically turn off. If a light does not turn on when the ignition switch is turned on, remains on without turning off, or lights up while driving, it indicates a malfunction in the related system. In such cases, seek professional help promptly for car inspection and repair to eliminate potential safety hazards.

Which batch of Mistra vehicles experienced engine cylinder scoring?

Mistra engine cylinder scoring occurred in the 2014 model with 1.8L engine. Reasons: Engine overheating caused by cooling system leakage/water shortage without timely replenishment; Severe oil deficiency due to engine oil leakage or excessive consumption; Prolonged high-speed or overload operation leading to excessive temperature. Definition: Engine cylinder scoring refers to evident longitudinal mechanical scratches and abrasions on cylinder walls within piston ring movement range. In severe cases, adhesive wear occurs, causing difficult engine starting or spontaneous stalling. Cylinder scoring constitutes a major engine failure incident.
