Introduction Diesel engines are marvels of engineering, known for their durability and efficiency. However, like any complex machinery, they can experience issues over time. One common problem that can affect diesel engines is blow-by. In this article, we’ll delve into what blow-by is, its causes, and potential solutions. What is Blow-By? Blow-by refers to the phenomenon where combustion gases, along with other byproducts, escape from the combustion chamber of an internal combustion engine, such as a diesel engine, into the crankcase. In a diesel engine, the combustion process generates high-pressure and high-temperature gases that, under normal circumstances, should be contained within the combustion chamber. However, when these gases leak past the piston rings and enter the space between the piston … Continue reading What Is Blow-By On A Diesel Engine And Its Causes?
