Abstract

Fuel temperature has effect due to engine performance. This research is aimed to get the effect of cross section heating area with radiator heat due to performance of gasoline engine. The experiments are conduct in Toyota Kijang 5K gasoline engine. The radiator heat is use to raise the fuel temperature by 8 mm diameter copper pipe. The pipe is varied as round, oval and nearly flat. Fuel flow channel is place in the heat pipe with 900 mm of length which placed at upper tank of the radiator.  The engine rotation speed is varied as 750, 1250, 1750 and 2250 rpm. Unheated fuel is use as a control. The research result shows the agreement that fuel temperature has effect due to fuel consumption. The result also shows that oval pipe has the lowest fuel consumption.   Keywords: fuel temperature, copper pipe, fuel consumption, radiator’s upper tank

Abstract

This   research   is   aimed   to   get   the   effect   of   electrode   surface   area   and   electrolyteconcentration  due  to  gas  volume  flow  rate  of  water  electrolysis.  The  surface  area  is  varied  as19.264 mm2, 38.528 mm2  and 57.792 mm2. The KOH electrolyte concentration is varied as 5 gram,10  gram,  15  gram,  20  gram,  and  25  gram  in  a  litre  aquades.  The  experiment  is  conduct  in  an electrolyzer.  HHO  gas  is  flowed  pass  trough  an  orifice  for  volume  flow  rate  measurement.  The research shows that the increase surface area and electrolyte concentration tend to increase gasvolume flow rate. The maximum gas volume flow rate happened at 57792 mm2  surface area and25 gram  KOH  electrolyte  concentration  which  is  0,00123  m3/det.  The  minimum  gas  volume  flow rate  happened  at  19264  mm2   surface  area  and  5  gram  KOH  electrolyte  concentration  0,00045 m3/det.

Abstract

Carburator air filter is an important part in automotive fuel system. Air filter is technicallymodified to increase the performance. This research is aimed to get the effect of air filter type due to motorcycle engine performance. The research is done by experiment using Suzuki Shogun 110 cc motorcycle. Air filter is vary as no filter, standard filter and modified filter. The engine is running at  1000,  2000,  3000  and  4000  rpm.  The  rotations  are  measured  with  tachometer.  Time  of  fuel consumption is measured for 10 ml gasoline. Experiments are conducted 3 times. The data is use to  get  fuel  consumption  and  engine  efficiency.  The  research  shows  that  carburator  air  filter  has effect due to engine performance. Modified filter has better performance than standard filter and no filter.

Abstract

Automotive technology development increase society need for transportation. It increase the demand of fossil fuel. This research is aimed to get the effect of magnetic field due to fuel consumption and engine performance. The experiment is done with Suzuki Smash 110 cc engine. Magnetic field is vary by electric current input as 1,2; 0,8 and 0,6 Ampere. The engine is running at 1750, 2000, 2250 and 2500 rpm. The result shows that the magnetic field has effect due to fuel consumption and engine performance. Magnetic field has lower fuel consumption and more thermal efficiency.
