All heavy-duty diesel truck engines derive energy from burning fuel which is initiated using the mechanism of the piston located in the cylinder block. Inside the cylinder, a combination of fuel and air is injected. The piston compresses the air and fuel together at high pressure. When the pressure is high enough, the spark plug ignites the gas and causes an explosion which sets the engine running. An average Heavy Duty Diesel truck engine consumes anywhere between 3,650 to 5,600 gallons (13,000 to 20,000 liters) of air to burn only one liter of fuel. This air, however, is polluted with various kinds of contaminants such as dust, smog, smoke and other particles which may or may not be visible to the naked eye. They induce impurity in the air and affects the air quality. This adulterated air can potentially damage the engine components.

Why Air filtration can’t be compromised

The Air intake happens only once, which means the filtration takes place only once. The air does not circulate in a loop like a fuel which can be filtered over and over again. Hence, a good air intake system is important. This necessitates the inclusion of air filters in heavy-duty diesel truck engines as po or air quality can impact the engine performance. Fleetguard, one of the best filter manufacturers in India, engineers air filters to deliver optimized air quality and provide the best overall performance and service life.


Regular maintenance of Air filter goes a long way

The contaminants in the air that are likely to enter the engine are pollen, dirt, soot, and dust. They may seem harmless at rest, but under pressure, they become highly abrasive. Air filters generally have cartridges containing a fine filter paper. The holes in it are only large enough to allow fine air to flow through while obstructing the path of unwanted debris. Over a time, the filter may get clogged or damaged due to constant attack by the sharp contaminants. To maintain the filter at an optimum level, this calls for a timely maintenance. A well-maintained air filter significantly improves the health of the engine in various ways.


Enhanced performance – While a clogged filter can be detrimental to the performance of the engine, a clear filter improves the efficiency and increases the output power.



Reduced emissions – The air-fuel mix is finely calibrated. Maintaining the filter helps in maintaining the equilibrium and optimize the fuel consumption, consequently reducing the emissions.




Increased life of Engine – The air is filled with dirt and debris which gets trapped in the filter causing wear and tear of your engine and other components. A prolonged and consistent exposure to these contaminants physically damages the engine. The timely maintenance of filter can defer the damage and extend the life of the engine.



To ensure a properly functioning engine and to reduce the wearing of components, an air filter should filter 100% of air and remove maximum contaminants. Thus, considering the above points, a good air filtration system in place can definitely deliver the best results.
