Parametric thermal analysis of permanent magnet synchronous motor by considering real time driving cycle is presented. As driving motors of electric vehicle, permanent magnet motors exhibit high efficiency and high power density. However, they are susceptible to suffer irreversible demagnetization and insulation failure of coils under severe thermal condition. Therefore, it is essential to precisely predict heat losses and temperature distribution in driving motors under real time driving cycle. The thermal behavior of the driving motor is analyzed by means of thermal parametric methods. Here we are using simulation software to measure the temperature distribution and heat losses in the Driving motor, when an electric motor is operated for a certain amount of time the motor produces heat because of the Heat produced by the motor the performance, efficiency and reliability of the motor is affected.

Waste cooking oils (WCOs) are renewable and in nature can be directly used as fuel into the compression ignition engines. However, the reduction in brake thermal efficiency and increasing smoke emission and oxides of nitrogen need to be solved. There are more techniques used past researchers to improves the performance and reduced the emissions characteristics of WCO. In this present work, an experimental investigation made on the effect of ethanol on engine's behavior using Waste Cooking oil (WCO) based dual fuel diesel engine. A single-cylinder diesel engine was operated and modified the intake to operate dual fuel mode at the maximum power output of 3.54 kW. Ethanol is introduced as primary fuel into the intake manifold and WCO as pilot fuel. The ethanol energy share (EES) of the total fuel was varied from 5% to 40% with a step of 5%, at fixed engine speed equal to 1500 rpm.

The search for a new renewable biofuel and aiming to make the environment clean is always a challenge for a researcher in developing a sustainable fuel for future mobility. In this context, vegetable oils were found as good alternative biofuels for diesel engines as they are biodegradable and renewable in nature. Most of the physio-chemical properties of vegetable oils are very closer to diesel. However, pure vegetable oils are expensive and using them to operate the diesel engine may affect the food supply chain. In view of this limitation, Waste Cooking Oil Biodiesel (WCOB) derived from waste cooking oil (WCO) was found to be very attractive solution for the above said constraints as they are easily available, renewable, economically and environmentally viable. This research aims at studying the effect of hybrid nano additives (i.e. Copper Oxide with Zinc Oxide) on performance and emission characteristics of a diesel engine fueled with Waste Cooking Oil Biodiesel.

Oxides of Nitrogen (NOx) emissions are considered as among the most harmful emissions globally having a direct influence on human beings and the environment. This work deals with a strategy to arrive at achieving lower NOx values consistently in mass production of single cylinder automotive diesel engines meeting BS IV Emission standards using the DoE technique for dimensional optimization of critical parameters. Catalytic converters and particulate filters are mostly used as after - treatment devices for compression Ignition (CI) engines for bringing down the limits (Values) of the pollutants from the tail pipes. But the real ingenuity lies in achieving the same effect through optimization of in - cylinder combustion.

Reliability and cost effectiveness of electronics demands its usage in all the wings of science and technology. Thus an attempt was made in this work to investigate the potential of using electronics for injecting primary fuel for the compression ignition engine used by farmers for agricultural purpose. In the first phase of the work, a new Electronic Control Unit (ECU) for primary fuel injection was developed and tested for its repeatability on fuel injection quantity for the different input voltages. Test engine was developed and tested under various load condition for its performance, emission, and combustion characteristics with neat diesel and Waste Cooking Oil Methyl Esters (WCOME) as baseline readings in the second phase of the work. In the third phase of work, the developed engine was modified to operate in duel fuel mode with developed ECU. In this work, ethanol was chosen as primary fuel due to its availability and less toxic nature as compared to other green fuels.

This paper investigates the performance and combustion characteristics of a compression ignition engine (CI engine) fueled with Used Cooking Oil Biodiesel (UCOB) and ethanol in dual fuel mode. In this study, UCOB was injected as the main fuel through a conventional mechanical fuel injection system. Various mass flow rates of ethanol were inducted as primary fuel through the engine intake manifold using a separate fuel injection system. Mass flow rates of ethanol were metered by an electronic control circuit. The engine test was conducted under different load conditions from no load to full load in a fully instrumented direct injection, water-cooled compression ignition engine. The results indicated that the dual fuel engine produced higher brake thermal efficiency, cylinder pressure, heat release rate with lower specific fuel consumption at a higher load condition. However, it was found that combustion characteristics improved marginally at the lower load conditions.

Waste Cooking Oil (WCO) is generated in large quantity worldwide due to the increase in population and change of food habits.
