Design Head for 4 Cylinder, 810 cc,water cooled, naturally aspirated Fire Fighting Engine complying to FM/UL standards.* Released part drawings involving modification with GD&T using ASME Y 14.5 and checked for DFMA after evaulating for structural and modal analysis using Ansys* Drive analysis with tolerance stack up, misalignment check, belt selection, tensions, min-max allowancesDesign Head for 4 cylinder,810cc,water cooled,naturally aspirated Industrial Engine in EPA modifications.* Organized the testing process from part procurement to fixture requirements for given modifications.* Testing and optimization using DOE in crankcase ventilation for limiting crankcase pressure between 0.5Kpa to -1.5KpaProject Leader for Bolted Joint analysis using VDI(verein deutscher ingenieure)-2230 standards* Designed Connecting rod and Main bearing cap Critical fasteners (with Torque- Angle relationships).* Created a prediction for cylinder Pressure vs. Crank angle using Wiebes function and rate of heat relase

Project Coordinator : Root Cause analysis for RPM variation in 6K engine series*Investigated using 4M and 5 whys method and audited supplier, assembly process and conducted customer site visits for failure in Electronic governor using power analyzer.*Stabilized the RPM variation from 60 to 25 using Ziegler Nichols and manual adjustment of PID tuning to comply with ISO 8528 G3 class.Project Coordinator : Failure analysis of fuel leakage and cracked injectors.*Root cause analysis of failed parts(Injector ,HPP and union nut) using CMM and Talysurf profiler.*Changed the routing of High pressure pipes to increase stiffness and increased the torque specifications for Union nuts.

This project is related to recover Uranium Dioxide fuel pellets from the rejected fuel element bundles.*Designed a cost effective machine using pipe cutters which are actuated by pneumatically controlled pistons.*High recovery rate of fuel pellets without resorting to lathe cutters which generally break the fuel pellets due to vibration.
