“…Lee et al [5], conducted an analysis of the dynamic behaviour of the solenoid valve while examining the phenomenon of electromagnetic field and flow through the exhaust channel [10]. In her work, Harantova [2]discussed a projectand analysis of the control and supply systems for injectors.Voltage of the injector power supply and pressure values in the fuel system at a given width of the control pulse (PWM -Pulse-Width Modulation)were analysed [9].At the same time, attempts were made, to achieve the highest possible efficiency and stability of the injector work. In [12], the method of fuel injector verification based on electric current characteristics and the possibility of correcting the operation of the injector by using appropriate control algorithms was presented.…”

The article discusses results of the laboratory experiments in which fuel injectors used in indirect injection internal combustion engines were tested. During the experiments, numerous dosing cycles of the injectors were performed while changing the control parameters, due to which, the dosing characteristics were developed and influence of applied parameters on the resultant fuel flow determined. Simultaneously, the voltage and electric current waveforms in the injector coil were recorded, due to which finding links between the electric current characteristics and the determinants of the injector work was possible. The investigation has shown that parameters of electric current constitute a precise criterion for assessing the operation of the solenoid valve, because fuel flow is created due to the work ofelectric current. Thus, by observing the changes in the current flowing through the valve coil,it is possible to monitor precisely the correctness of the process of opening the flow and the electric current intensity, at which the flow began and to determine the mechanical quantities such as fuel dose and pressure. As a result, a characteristic is developed, that provides the links between the fuel pressure and the electric current at the point of lifting the needle, which is quite a novel approach. Such a characteristic can be used in diagnostics and control of fuel injectors as well as all kinds of electromagnetic valves

“…The injection system is controlled using an electronic circuit that allows the proper air mixture into the chamber. The fixed ratio is around 14.7:1, meaning that for every one part of fuel 14.7 parts of air are required for combustion to be effective [12]- [14]. Fig.…”

As the technology is evolving and upgrading, more ways are being founded to tackle global warming and the emission of greenhouse gases. Introducing hybrid cars in 1997 was a milestone towards this initiative, which not only decreased fuel consumption but also lowered the on-road emission of harmful gases. However, in developing countries where masses are using motorbikes as a primary source for commuting. Industries are in process to manufacture hybrid motorbikes which are eco-friendly and light in build. This paper will be addressing the comparative analysis of both types of bikes i.e. the new hybrid bikes and fuel injection motorbikes with associated pros and cons.

“…Modifications of the injector work are reflected in the combustion process in the engine [21], which translates into a change in the number of toxic substances in the exhaust gases. Additionally, changes in the dosage resulting from the injector's improper operation while changing its characteristics [22] entail difficulties in starting the engine. The engine controller manages the ratio of the fuel to air supplied to the combustion chamber; it also manages the ignition, throttle position, idle speed, EGR valve operation, and other assemblies, depending on the engine type [23,24].…”

This paper discusses a method of diagnosing electromagnetic valves of injection systems in combustion engines. Based on multiple analyses of electrical quantities occurring in the course of the electromagnetic injector work and physical relationships between them, the quantities have been demonstrated on which the fluctuation of the electromagnetic force in the injector depends. Moreover, the results of its fluctuations have been mapped to the electric quantities controlling the fuel injector’s work. The research has shown that the current and voltage waveforms contain information on electrical properties of the injector coil and its mechanical properties determining the injector’s technical health as well as that of the fuel system.
