What does it mean when the car engine light turns yellow?

When the car engine light turns yellow, it indicates that there is a fault in the engine that needs to be checked and repaired promptly. The proper operation of the engine relies on sensors, including the air flow sensor, intake air temperature sensor, oxygen sensor, coolant temperature sensor, and camshaft position sensor located around the engine. If any of these sensors malfunction, it may cause the engine to fail to operate correctly, triggering the engine warning light. Additionally, using low-quality gasoline can also lead to the engine warning light illuminating. If the engine warning light comes on, it is recommended to drive immediately to a repair shop or a 4S store to have professional technicians read the vehicle's fault codes.

What Are the Functions of Engine Oil in a Car?

Engine oil in a car serves the following functions: 1. Lubrication and friction reduction, forming an oil film between two sliding component surfaces to ensure smoother operation; 2. Cleaning and dispersion, flushing away surface contaminants on components through the flow of oil; 3. Cooling and heat dissipation assistance for components; 4. Sealing and leakage prevention, forming a seal between the piston rings and pistons via an oil film to prevent exhaust gases from entering the crankcase after combustion; 5. Corrosion and rust prevention; 6. Shock absorption and cushioning. Engine oil, also known as engine lubricant, consists of base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of the lubricant.

What is the engine temperature in summer?

In summer, the normal engine temperature is 90 degrees. The car engine requires a certain operating temperature for normal operation, and temperatures that are too high or too low are not conducive to the normal operation and performance of the engine. On the other hand, the heat generated by the engine's operation is difficult to meet the demand with conventional air cooling, so water-cooled heat conduction design is widely used in car engines. The function of the cooling system is to keep the engine operating within the most favorable temperature range to improve the engine's power, reduce engine wear and fuel consumption. Both excessively high and low temperatures can have adverse effects on the engine's operation. The engine coolant temperature is not the lower the better, nor the higher the better, but should be kept within a certain range.

What does the "!" symbol on the car mean?

There are three situations when a car displays the "!" symbol: 1. A triangle with an exclamation mark in the middle indicates a general fault warning light; 2. A circle with an exclamation mark inside brackets is the brake system warning light, which illuminates when the parking brake handle is pulled up and automatically turns off when the handbrake is released; 3. A horizontal line with an exclamation mark below brackets is the tire pressure monitoring warning light, which lights up when the tire pressure is insufficient. The car dashboard is a device that reflects the working conditions of various vehicle systems, including common indicators such as the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Standard gauges include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge.

Where are the brake and accelerator positions in a manual transmission car?

In a manual transmission car, the brake and accelerator are located at the bottom of the left side of the driver's compartment. The leftmost pedal is the clutch, the middle one is the brake, and the rightmost is the accelerator. The brake pedal is used to reduce speed and stop the vehicle, and it is used very frequently. The accelerator pedal, also known as the throttle, is part of the car's fuel supply system. By controlling the amount of pressure applied, it regulates the engine throttle opening, controls the air intake, and the computer adjusts the fuel supply, thereby controlling the engine speed. The clutch pedal is the control device for the clutch assembly in a manual transmission car and serves as the 'human-machine' interaction between the car and the driver. Proper operation of the clutch pedal directly affects the car's starting, gear shifting, and reversing.
