Main power indicators for diesel engines

2016-08-15


The power indicator of a diesel engine is mainly measured in terms of efficiency. The actual output power measured from the crankshaft of a diesel engine, which is the effective work done per unit of time, is usually measured in horsepower.

The so-called effective power is the power that we can actually use. Because the diesel engine work engineering to overcome internal friction losses, drive a variety of ancillary equipment and other reasons, the diesel engine cylinder power issued than the effective power. So the effective power is the diesel engine cylinder power issued after deducting various losses we get the power.

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.
