The pre-mixer model of new intake manifold system application for multi-fuel spark ignition engine by numerical investigation and comparison

Abstract

This paper is to study about the development of variable intake manifold for spark ignition engine. Variable intake manifold by numerical is one of the methods in optimizing the performance of an engine when changing or mixing fuel. It has been found that the geometric of new multi fuel intake system configurations of spark ignition engine plays a vital role in engine performance. The main aims of the paper are to assess the comprised thermal efficiency and numerical engine performances for the multi fuel small spark ignition engine of modified intake system unit. This engine type is unique, entirely conceived by the author and has not previously been reported in the open literatures. It is called the pre mixer of multi fuel and air. It was compared with the old intake manifold system of fuel injectors [8] and carburetor [10]. It makes this system can adjust the fuel mixture, or a variety of gasoline with ethanol, that aimed at engine improvements through thermodynamic engine indicated power (kW) with the
