Introduction
Engines play a very important role in modern lives, especially diesel engines. There are many places need to use diesel engines, such as vehicles, ships, generators, etc. Despite of its great contribution in human’s lives, diesel engines also release emissions that damage the environment. Especially, it releases blue smoke, which is harmful for people’s lungs. This article will walk through the reasons for diesel engine’s blue smoke, and the measures to reduce its emission.
Reasons of Diesel Engine Blue Smoke
The cause of diesel engine blue smoke is caused by a few of different factors. In general, it’s caused by a fuel that contains high sulfur content, which is not burned fully by the combustion process in engine. The remaining fuel is then ejected out with unburned particles, mixing with exhaust gas and appearing as the blue smoke.
Sulfur content is a common issue, especially when the diesel is aged, or due to incomplete refineries processes. To be more specific, the following factors can also contribute to the blue smoke of diesel engines:
1. Low comprssion: poor comprssion can contribute to blue smoke, due to the insufficient temperature of the combustion process.
2. Damaged piston or sealing: damaged or worn out piston or sealing can cause the fuel leakage, and results in diesel engine blue smoke.
3. Too much oil consumption: too much oil consumption means more fuel is not burned fully and returned to the exhaust pipe, making the blue smoke more visible.
4. Overheating: overheating can cause more fuel to burn, forming bigger, more visible particles in the exhaust.
Measures to Reduce Diesel Engine’s Blue Smoke
There are a few steps we can take to reduce the diesel engine blue smoke. These measures include:
1. Using Better Quality Fuel: using better quality diesel with lower sulfur content can reduce the blue smoke. Mixing with other fuels such as kerosene, biodiesel or alcohol can also help to reduce the emission.
2. Ensuring Proper Compression: to ensure proper compression in diesel engines, regular maintenance and inspection of the engines is essential. This includes checking for wear and tear, and replacing any damaged parts.
3. Reducing Oil Consumption: reducing the oil consumption can help reduce the blue smoke emission from diesel engines. This can be done by following the instruction for the engine, and making sure the oil is changed regularly.
4. Reducing OVerheating: to reduce the overheating in diesel engines, regular maintenance and inspection is also important. This includes checking for any damages or defects, and ensuring that the cooling system is working properly.
Conclusion
In summary, the blue smoke from diesel engines is caused by a few factors, such as sulfur content, poor compression, damaged piston or sealing, too much oil consumption, and overheating. To reduce the diesel engine’s blue smoke, a few measures can be taken, including using better quality fuel, ensuring proper compression, reducing oil consumption and preventing overheating.
