EFFECT OF AIR FILTER TYPE ON THE PERFORMANCE OF THE 110 CC INJECTION MOTORCYCLE

The air filter is one of the most important components in the combustion motor which functions to filter the air before it enters the combustion chamber. The flow resistance caused by the air filter greatly affects engine power and torque and also affects fuel consumption. The results showed that the use of various types of air filters occurred changes in power and torque on injection motorcycle engines, standard air filters of 7,349 (HP) and 7,429 (Nm) were rotated at 6829 RPM, foam air filters were 7,254 (HP) and 7,648 (Nm) rotated 6862 RPM, Ferrox air filter 7,382 (HP) and 7,737 (Nm) rotated 6794 RPM, without filter 7,268 (HP) and 7,737 (Nm) rotated 6794 RPM. The increase in power and torque is seen in the Ferrox air filter, while the decrease in power occurs without an air filter. Effect on fuel consumption in 20 ml rotated 3000 RPM, for standard air filter 1 minute 57 seconds, foam air filter 2 minutes 13 seconds, Ferrox air filter 1 minute 47 seconds, and without air filter 1 minute 22 seconds, the fastest time in consumption fuel in the experiment without an air filter is 1 minute 22 seconds while the longest time on the foam air filter is 2 minutes 13 seconds.
