In this study the air filter system was improved by the increase the length of air sleeve and add another paper filter at the top. The life service of the three types of air filtering systems was investigated by collecting a data air filter replacing after achieving a different of agricultural applications including (plowing, soil straightening, seeding, pesticides, herbicides and harvesting). The innovative design shown the best performance and long life service. Moreover, the air filtering system oil bath with centrifugal and paper filter provided long life service three times better than the single air filter.

The wear on engine parts consider a significant one of these factors. The common wear reason is the atmospheric dust that escapes from the filter(s) into the combustion chamber of the engine or carried to it with the oil lubrication (Toma, 2016). Vehicles' air filters are usually made of felt or cellulose paper. There are several materials are used in different types of dry air filters including (paper, gauze, foam, cotton, stainless steel). Moreover, there are other kinds of air filter such as oil bath filter and water bath filter. These are placed in cylindrical or prismatic attachments, depending on the available space and are specially designed for frequent maintenance activities. If an internal combustion engine was operated without the air filter that would lead to be subject to wear 10 times faster compared with an engine which working with air filter (Herbert, 1991). The regular maintenance, including removing the solid particles using high pressure air flow or replace the filter represents an important sign in engine service life. With the passage of time, the hard particles will accumulate in the filter causing decline in the intake air flow rate of the engine and consequently will affect the engine efficiency(Bugli, 2000).The air filter marketplace is focused by the performance requirements for engine air induction systems such as, high dust-holding capacity, low flow restriction high fractional efficiency, long life service- designs, small, compact components, integrated air intake & silencing system, stable air intake systems with non-evaporative emissions, exclusive designs, ideal volume to be fitted into the available space (Jhon, 2016).Acceleration performance on vehicles increasing with clean air filter (Norman, 2009).Engine lifetime, IC engine emission and fuel consumption depend on the air filter system design and its performance (Petal, et.al, 2013). In tractors, air filter(s) usually, put in a high tube to reduce the amount of dust or soil particles that can move into the engine. Some brands of agricultural tractors use the dry air filter and other use a combined air filter (dry air filter and oil or water bath filter) in addition to centrifuges that can be Original Article International Journal of Mechanical and Production Engineering Research and Development (IJMPERD) ISSN(P): 2249-6890; ISSN(E): 2249-8001 Vol. 9, Issue 1, Feb 2019, 541-544 © TJPRC Pvt.
