Abstract
The pleated air filter is a device composed of fibrous flat panels that remove particulates such as dust, pollen, mold, and bacteria which suspended in the airflow. The air filter must supply the vehicle’s engine by a clean air with lower values of air pressure DROP through the filter media. The air filter must be located in the air intake system of vehicle engines to supply the engine by a clean air with lower values of air pressure DROP through the filter media. A fuel consumption rate is a very important issue for a vehicle’s selling companies and consumers especially. Therefore, the first criterion for comparing by consumers is the car choice based on the least fuel consumption in addition to being durable and less maintenance. To achieve competitiveness among automobile manufacturers to reach the highest sales ratio makes it necessary to provide technologies that attract the attention of consumers. This work experimentally and numerically investigated the pleated air filter with different parameters leading to improve performance. The approach of the study is to improve the I.C engine performance. The test parameters involve; pleat length, pleat height, filtering media thickness, air velocity, elapsed time to consume a constant fuel volume, and dust load. Experiments are achieved with air velocity ranging 1:5 m/s whilst the fuel quantity is kept constant at 25x10-6 liter.
Three different filters are experimentally evaluated which are; loaded filter, original filter, and optimized filter. Numerical CFD modeling is developed using FLUENT 16.0 commercial code. Filter media is generated and set as a porous zone. The validation criteria are accomplished to extend the study parameters, in addition, to investigate the pleated air filter under extra ranges of different parameters. Findings showed that; the pressure DROP decreases at higher pleat height and lower pleat height. The engine fuel consumption is decreased with the increasing of the engine torque.
