Summary:

In recent years the fuel injection technology has taken a greatleap in two-wheeler industries both in terms of having leanemissions and in terms of improving efficiency. Especially in amarket like India where fuel efficiency is given, as primeimportance and fuel contamination duly exists, it becomes all themore a bigger challenge to address to these kinds of problems bysome means.The main function of the fuel system is to make sure rightamount of fuel is injected into the intake manifold at right timewith the help of Electronic Control Unit. Variation from the rightquantity and quality of fuel leads to partial burning and finallyto more emissions and poor performance. So monitoring fuelpressure, there by the quantity and fuel quality is very muchimportant to reduce emissions and to achieve desiredperformance.The entire fuel delivery system is split into several subsystems viz: fuel pump - a PMDC (permanent magnet DC motor) motorto pressurize the fuel coming out of the fuel tank, fuel regulator- spring type mechanical regulator to maintain the pressure near to2.5 bar (2.5*10⁵ Pascal) constant, fuel rail - to hold thepressurized and regulated fuel for the system and injector - opensup for the desired quantity of the fuel into intake manifold withhelp of engine control unit acting as trigger to it.In the first phase of this paper, a 1st principles-basedmathematical model of the fuel system is proposed.This model helps to understand the dynamic behavior of thesystem. The work is further extended by developing another dynamicmodel using system identification tools. Both the models arevalidated with experimental results.The main aim of this paper is to develop a control-orientedmodel, which replicates the behavior of the actual plant. The abovemodels are compared for the computational efficiency, as one of theabove models will be used for designing different controlstrategies in future
