What level of exhaust gas colour is considered poor smoke emission?

2016-08-25


The exhaust of a normal working diesel engine should be close to colourless or slightly light grey, if the exhaust has a colour perceptible to the naked eye, it indicates that the diesel engine is not working properly. But exactly how much exhaust smoke is allowed by normal work? At present, China does not have clear provisions, and the measurement of exhaust smoke is not a unified method. Therefore, the assessment of the exhaust smoke is still based on direct observation and practical experience.

Smoke not only pollute the atmosphere, deteriorate the working conditions, and will make the diesel engine temperature rise, serious carbon coking and thus shorten the service life of diesel engines. Therefore, to be eliminated as far as possible.

Factors to consider when choosing a diesel engine

the use of diesel engines. For frequent starting and often moving machinery, such as tractors, agricultural vehicles, mobile power stations, etc., can choose light high-speed diesel engine; for fixed power devices, such as agricultural irrigation and drainage, agricultural by-products processing machinery supporting power, you can choose a lower speed and the potential of a larger diesel engine. At the same time, for agricultural power, most of the time long-term continuous operation, so good economy is very important.

What are the characteristics of the wear process of cylinder liners?

To the normal technical condition, because with the parts fit well, lubrication conditions are improved, in a longer working time, wear is slow and uniform. When due to wear and cylinder gap more than a certain value, due to the gas and oil leakage and moving parts of the knock and other factors, wear and increase.

Basic requirements for diesel engines

Basic requirements for diesel engines

This question concerns how to evaluate the diesel engine. With the development of socialist construction cause, China's diesel engine models continue to increase, the performance indicators gradually improve and enhance. At present, the domestic civilian diesel engine has more than one hundred kinds, there is a comprehensive use of high degree of general models, but also for special purposes of special models. In this case, how to correctly evaluate, reasonable choice of diesel engine is a very important issue.
