Abstract

Combustion process in diesel engines produce vibrations which tend to be larger so that the discomfort in driving greater, and the damage is more anyway because of the vibration. The shape of the air inlet on the diesel engines are generally not the same from when air enters through the air filter to each cylinder having major losses, thus affecting the volume of air entering each cylinder. This will cause the products of combustion in each cylinder is not the same so it will cause greater vibration when the machine is turned on. For the combustion process in diesel motor vehicles used pure compressed air as a medium for heat generation that occurs when the diesel spray combustion process, the amount of air to be compressed each cylinder is affected by the shape of the intake manifold (inlet). Short length inlet manifold determine the air flow into the cylinder when the suction step, wherein the amount of air flow determines the magnitude of the explosion after the combustion process. Differences blast from the combustion process of each cylinder will result  in  greater  vibration  therefore  require  equalization  of  the  volume  of  air  to  be compressed each cylinder so that the vibration is reduced by means of changing the shape of the intake manifold using the parallel tube expected to allow outside air going into the cylinders when the intake stroke. Decreased vibration occurred from 1000 rpm, and the rotation of 3000 rpm, the value of the amplitude of the intake manifold is changed is smaller than the standard value of the amplitude of the intake manifold resulting in a decrease in the amplitude of the cylinder head and cylinder block is very significant for each rpm
