This research aims to the development of intake restrictor of a formula SAE car engine which is of 300cc parallel twin cylinder engine. In this paper we have considered different venturi designs which have different convergence and divergence angles. The main aim is to optimize the pressure and velocity of air which tends to offer better combustion reflects in performance. The parameters which are to be considered for design as well as analysis are mach number, intake velocity, mass flow rate, etc.., To perform this research we have chosen the Ansys fluent software tool and the analytical calculations were made for standard design. It is observed that the continuous variations in converging and diverging angles offers better results in both pressure and velocity characteristics of air entering for combustion. © 2018 Authors.

K. Bhavani and Sivanesan Murugesan, “Diesel to dual fuel conversion process development”, International Journal of Engineering and Technology(UAE), vol. 7, pp. 306-310, 2018.[Abstract]


This paper aims to develop a process for conversion of Diesel Engine for Dual Fuel operation which is basically designed to reduce the economic costs and pollutant Emissions. The increasing cost of Diesel Fuel leads to the necessity of an Alternate fuel, i.e Compressed Natural gas (CNG). In this research a 16 cylinder, 50.25liter, Turbocharged After cooler V-shaped Engine is used for the conversion into Dual Fuel Engine. Dual fuel engine can be operated on both Diesel and CNG modes simultaneously. In this Engine the Air and CNG are mixed in required ratios in an Air- Gas mixer and the mixture is injected into the Combustion chamber. As Gaseous fuel CNG cannot selfignite itself because of its high Auto ignition temperature a required amount of Diesel is injected into the Combustion Chamber at the end of compression stroke for ignition purpose which is known as Secondary fuel or a PILOT FUEL. This paper tries to show the process development of converting Diesel Engine for dual fuel operation on multiple platforms. © 2018 Authors.

Sivanesan Murugesan and Jayabalaji, G., “Modelling, Analysis and Simulation of Clutch Engagement Judder and Stick-Slip”, SAE International Journal of Passenger Cars - Mechanical Systems , vol. 10, no. 1, pp. 54-64, 2017.[Abstract]


Analytical and numerical study is carried out to study the behavior of stick-slip and judder phenomenon during engaging and disengaging of the automotive clutch. For this purpose, a four degree of freedom torsional power train lumped mass model is developed. This torsional vibration system includes engine-flywheel, clutch, gear box and vehicle drive line, which are connected to each other by shafts. Equation of motion of the system is developed and initially a stability analysis is carried out for various gradients of coefficient of friction using eigen value analysis. Later, a numerical simulation is carried out to analyze the judder and stick-slip phenomenon using commercially available mathematical tool MATLAB. It is observed that the clutch stick-slip is increased with increase in external torque and clutch pressure fluctuations.

Sivanesan Murugesan, Chinnasamy, L., and Abhijeet Patil, “Developing and Simulating the Duty Cycle on Engine Dynamometer based on Engine RWUP”, SAE Technical Paper , 2015.[Abstract]


Appropriate test cycle is required for engine testing. To do so, a new methodology is developed for deriving Engine Test Cycle based on real world duty cycle. Transient speed and load is to be collected from the functional engine on the field. The duty cycle for cyclic operation will be developed from the actual transient speed and load conditions. An iterative process and the comparison of chi-square statistical data is used to categorize typical microtrips, segments of engine operation collected during performance of certain activities. Different microtrips of all activities were combined together to make up a cycle of operation and test cycle as well. These data's are compared to statistical data which is used to illustrate the raw data. On successful comparison, the transient test cycle is validated on the test bed. To facilitate further engine testing, the cycle is transformed into a schedule of torque and speed points at One second intervals. FTP (Federal Test Procedure) is used for normalizing the Data. From the conducted work a representative test cycle is developed for engine testing with respect to the application, also a general methodology is derived for engine test cycle development.

Sivanesan Murugesan, Prem Kumar P. S., Padmanaban G, Karthick M, and Vasantharaj C., “Vehicle Parking Mechanism using C.G Point Concept”, Indian Technology Congress (ITC 2014), Bangalore. 2014.[Abstract]


Parking of vehicles usually needs some extra effort and space. It gives more uncomfortable feel to the person who drives the vehicle. If it is a dense condition the vehicle maneuvering is worse. For the physically challenged people the vehicle parking process is still convoluted. Our current proposal is going to minimize these difficulties and make these hard situations into ease. The proposed mechanism comprises of a gear and lifting arrangement, sensors, control switches and cam. The mechanism will work based on the Centre of Gravity (CG) of the vehicle. Using these mechanism human efforts can be minimized. A switch is placed in the driver’s access area, to lift the vehicle as per the required height. Initially, before lifting the vehicle to the required height, the CG point of the current weight has to be determined. Once the driver operates the switch, lift mechanism will extend out and use ground as a support to lift the vehicle. After the vehicle is lifted from the ground the whole base of the vehicle will be attached to the electronic weighing gauge. Once weight is determined by the weighing gauge the value will be given as the input to the control system to calculate the current CG position of the vehicle. The circuit will verify the coincidence of the neutral axis of lifting mechanism and neutral axis of the gear arrangement (Vehicle CG point). If there is a misalignment, the cam mechanism is provided to align both of them (lifting mechanism and gear arrangement). At this stage the vehicle is brought into the stable position and the signal is given to the driver. Once signal is intimated, driver is allowed to lift the vehicle to the required height and he can rotate the vehicle using the control stick provided. Also the base of the jack is provided with wheel arrangement, so that the vehicle can be moved when it is in lifted position. By implementing this stringent condition will be made simpler. This paper thoroughly discusses the possibility of CG point parking mechanism implementation in vehicles. This study concludes the effectiveness of this mechanism during parking of the vehicles

Karthick M, Prem Kumar P. S., Padmanaban G, Sivanesan Murugesan, and Vasantharaj C., “Aircraft in-built parking system using lifting and rotating gear mechanism”. 3rd World Conference on Applied Sciences, Engineering and Technology , Kathmandu, Nepal, pp. 464-467, 2014.[Abstract]


There are various sizes of aircrafts with different payload conditions are in use. The aircrafts are long,medium and short sizes; and also enough space is required for parking process of the aircraft. While parking theaircraft, pilot faces more difficulties such as required time for parking, fuel consumption etc. The pilot getsstressed by handling lot of controls to park the aircraft and he needs additional ground team support. The basicrequirement for a parking and storage facility are the runway infrastructure, it should be able to accommodatethe aircraft in general weather conditions. Parking of the aircraft includes planning, execution of a parking sitelayout, it’s to provide the short, medium and long term parking of the aircraft with more ease. The spacingbetween the aircrafts has to be sufficient for easy access and movement. Poor parking procedures result inexpensive damages to the aircrafts. These are all some of the difficulties during the aircraft parking procedures.Aircraft equipped with triangle landing gear are generally towed by attaching a bar to the axle of the nose wheel.They may also be towed forward or backward. Our proposed mechanism is expected to minimize thesedifficulties and make this hard situation into easier ones. This paper addresses a mechanism comprises of a gearand lifting arrangements, sensors, control switches which assists the pilot for ease parking. The liftingmechanism fitted on the landing gear/ fuselage of the aircraft. The whole weight of the aircraft will act on thelanding gear/ lifting mechanism. Separate jack is proposed to use in the respective landing gears/ liftingmechanism. When the aircraft is lifted using the lifting mechanism the whole weight will be acting on themechanism, this lifting mechanism uses ground as support for lifting the aircraft. A push switch can be placed inthe cockpit area to lift the aircraft for the required height. A sensor is placed in the lifting mechanism to detectthe malfunctioning and ensuring all the mechanism get lifted up simultaneously. When the pilot operates thecontrol switch, the lifting mechanism will take ground as a reference and the aircraft will get lifted. Then thelanding gear can be rotated as per the angle required using gear mechanism. In case of triangle landing gear, ourproposed mechanism used to rotate nose wheel for required angle and also rotate main wheels. This mechanismwill be very helpful during the maintenance & overhaul time to ease the engineer’s effort.
