What Causes Black Smoke from Diesel Engine Exhaust?

Diesel engine exhaust emitting black smoke may be caused by the following reasons and solutions: 1. Exhaust pipe blockage. Solution: If the exhaust pipe is blocked by excessive soot, it should be cleaned. 2. Incorrect valve clearance adjustment or poor valve sealing line contact. Solution: Check the valve clearance, valve springs, and valve sealing condition. 3. Uneven or excessive fuel supply from the high-pressure fuel pump to each cylinder. Solution: Adjust the fuel supply to achieve balance or keep it within the specified range. 4. Delayed fuel injection. Solution: Adjust the fuel injection timing advance angle. 5. Poor performance or damage of the fuel injector. Solution: Remove, clean, and inspect the fuel injector. 6. Incorrect fuel injector model selected. Solution: Replace with the correct model of fuel injector. 7. Poor diesel quality or incorrect grade. Solution: Use clean and qualified light diesel. It is recommended to choose diesel grades as follows: No. 0 or +10 in summer; -10 or -20 in winter; and -35 in extremely cold regions.

Can 15w40 Engine Oil Be Used in Winter?

Whether 15w40 engine oil can be used in winter depends on the temperature conditions of the local winter and summer seasons. The specific judgment method for whether 15w40 engine oil can be used in winter is as follows: 1. 15W40 engine oil is suitable for use in temperatures above -20℃. Since engine oil has a certain freezing point and viscosity, i.e., an applicable temperature range, and the winter temperatures vary significantly between regions such as northern and southern China, the usability of 15W40 engine oil depends on the local winter and summer temperature conditions. 2. 15w40 engine oil can be used in southern regions during winter, but it is not suitable in northern areas like Harbin where temperatures are much lower. 3. The meaning of 15W40: The number before the W indicates the low-temperature fluidity of the engine oil, or the minimum applicable temperature. The smaller the number, the better the low-temperature fluidity and the lower the applicable minimum temperature. 15 indicates that the minimum applicable temperature is -20℃, and its low-temperature fluidity is relatively average. 40 represents the viscosity value of the engine oil, which is a relatively high-viscosity oil with good high-temperature protection performance.
