Analysis of Influence of Extension in The MAF (Mass Air Flow) Sensor on Power and Consumption of Fuel in The Engine Model (B401RA)

Abstract

MAF is an electronic component in the form of a sensor that is used to transfer mass flow determined by the ECM to
determine the fuel injected. Based on Technical Research on 8/3/2016 engine knocks occur during acceleration in the vehicle with
the model code (B401RA) because the detection of air entering the detection area of the MAF sensor is less than optimal, thereby
increasing fuel injection volume and ignition time in the cylinder, causing knock to the machine because the ignition time is too
fast. Therefore, improvements made to the MAF sensor by changing the size of the MAF sensor, from the standard size (30 x 10
mm) to the size (32 x 22 mm). By enlarging the outer appearance of the MAF will expect not to occur ignition earlier so that
replacing the fuel is more suitable according to engine needs. From the research results obtained, MAF sensor modification can
increase Power by 5.56 kW and reduce fuel consumption by 0.00009 kg / kW-hour at 6000 Rpm. While on average there is an
increase in each engine speed for Power of 3.24 kW and consumption of fuel consumption of 0.00009 kg / kW-hour.
