Why Does a Diesel Vehicle Emit Blue Smoke?

Diesel vehicles emit blue smoke because engine oil has mixed with the fuel and entered the combustion chamber. This can occur due to several reasons: overfilling of engine oil, wear beyond the limit of cylinder liners, pistons, and piston rings, or aging of valve stem seals. When piston rings are damaged, cylinder leakage occurs, allowing oil to enter the combustion chamber. The primary symptom of an engine burning oil is blue smoke from the exhaust pipe. Other signs include engine shaking during idle, significant oil loss within a regular maintenance cycle (without any leaks), indicating that the vehicle is burning oil and requires immediate maintenance.

Is 4 liters of engine oil sufficient for the Roewe RX5?

The Roewe RX5 requires 4 to 5 liters of engine oil, so 4 liters is sufficient. Below are methods to determine when to replace the engine oil for automotive diesel generators: Observing bubbles in a glass test tube: Use two glass test tubes, each with a diameter of 0.5 cm and a length of 20 cm. Fill one with 19 cm of new engine oil and the other with used engine oil. Seal both tubes and invert them simultaneously. Record the time it takes for the bubbles to rise. If the difference between the two times exceeds 20%, it indicates that the viscosity of the used oil has decreased significantly, and it should be replaced. Comparing colors on white filter paper: Place a drop of new engine oil and a drop of used engine oil on white filter paper for comparison. If the used oil drop contains many black spots, it means the oil has not deteriorated and does not need replacement. If the oil appears dark brown, it has deteriorated and should be replaced. Turn off the engine and wait for about 5 minutes. First, clean the oil dipstick, then insert it into the dipstick guide hole, and remove it to check. The oil level should be between the upper and lower marks to be considered appropriate. Choosing the right engine oil: Selecting high-quality engine oil can make your car more durable and powerful. Good engine oil, especially fully synthetic oil, not only protects the engine and reduces the frequency of oil changes but also saves on gasoline expenses.

What are the reasons for a car's air conditioning not cooling?

The reasons for a car's air conditioning not cooling are: 1. Lack of refrigerant: Car air conditioning systems generally require refrigerant replenishment every 2 to 3 years, with most losses occurring due to leaks. If the air conditioning stops cooling after refrigerant refill and then fails again after some time, the system should be checked for damage; 2. Dirty condenser: When the condenser is blocked by debris, it can cause engine overheating or air conditioning failure; 3. Damaged throttle valve or expansion valve: Malfunctions in these components will directly result in air conditioning failure; 4. Worn or loose belt; 5. Damaged air conditioning flap.

What is the difference between China 5 and China 6?

The difference between China 5 and China 6 lies in their emission standards: China 5 allows a total hydrocarbon emission of 100mg per kilometer, non-methane hydrocarbon emission of 68mg per kilometer, and nitrogen oxide emission of 60mg per kilometer; whereas China 6 reduces these to 50mg, 35mg, and 30mg per kilometer respectively. After the official implementation of the China 6 standard, the main impact will be on the production, import, sales, and registration of new vehicles. New vehicles meeting China 5 standards will no longer be allowed to be registered or licensed. However, existing China 5 vehicles that have already been registered and licensed can continue to be used without affecting their normal annual inspections and can also be traded as used cars.

What is Automotive Crystal Coating?

Automotive crystal coating is a reliable paint surface sealing technology that provides efficient and long-lasting protection for the car's paint, preventing environmental factors from affecting the paint's color. The concept of automotive paint crystal coating was introduced to differentiate it from traditional waxing, sealing, or coating methods. The fundamental requirement of crystal coating is that the material used must be SIO2 inorganic matter, capable of forming multiple structures on the treated surface. Automotive crystal coating creates an isolation layer on the surface through the action of high-molecular polymers. This isolation layer possesses functions such as UV resistance, oil resistance, low surface energy, and hydrophobicity, thereby protecting the paint surface. The hardness of the diamond crystal coating reaches 6H, compared to the 2H hardness of ordinary car paint, which can prevent most minor scratches. Additionally, it has an elastic recovery function, protecting the vehicle from daily minor scratches.
