PENGARUH PEMASANGAN SIRIP PENGARAH PADA BUFFER TERHADAP UNJUK KERJA MOTOR BENSIN
Abstract: Perfect combustion
can improve engine performance and save fuel consumption. One of the
requirements perfect combustion is a homogeneous mixture of fuel and air when
entering the combustion chamber. Air and fuel mixture to become homogeneous in
case of turbulence in the mixing. Buffer with director fin is used to provide
additional mixing time between air and fuel at the same time create a turbulent
flow before entering the combustion chamber. In this study the buffer fitted
with director fins with different variations. The number of fins variation used
in this study are 3, 4, 6, 8 and 10 with a variation of the angle are 45o and
60o. The analysis was conducted on the effective power and torque output and
the FC (Fuel Consumption) needed from each variation condition buffer. From the
results of testing on the condition of the buffer with 3 fins angled 60o obtain
the highest effective power increase 5.92% and increase in the highest torque
2.66% when compared with the buffer without fins. The lowest FC (Fuel
Consumption) in the buffer with 3 fin angle 60 ° when compared with the buffer
without any fins at 4000 rpm with a 11.15% difference.
