What is the purpose of the air cleaner in an engine?

The purpose of the air cleaner in an engine is to filter the air intake. Air cleaners are essential components that prevent dirt, dust, and other contaminants from entering the engine intake system. Clean air is necessary for the combustion process, as it allows for proper fuel combustion and efficiency. When contaminants are filtered out, the engine can perform optimally, leading to improved performance, better fuel efficiency, and reduced emissions. Without a functioning air cleaner, harmful particles could cause wear and damage to the engine components, ultimately leading to mechanical failure. This highlights the critical role that the air cleaner plays in maintaining engine health and longevity.
