The hybrid structure of Engine Mounts made of rubber casing with cast iron reinforcing. Use of two materials made it unique both in application and testing. The rubber provides damping for engine vibrations and the cast iron provides necessary strengthening to hold the heavy engine in place. In this research paper the FEA (Finite Element Method) methodology is being discussed to evaluate and optimize the design analysis to enhance overall engine mount capacity. The existing and modified designs are validated and considerable improvement is being observed in modified design in physical testing. Accurate modeling of engine mounts assembly is presented in this paper. FEA analysis results have good correlation with physical validation for both designs. Impact of design parameters of rubber mounts has been presented.

In an electric vehicle, engine is replaced with battery and transmission is replaced with traction motor. Thermal management of electric battery and motor became a necessary evaluation step in the design and development process of electric vehicles. The temperature of the traction motor coolant is required to be maintained below 600C to ensure proper functioning of the system. Coolant takes away heat from traction motor, motor controller along with an on-board charger in battery charging and discharging conditions. In this paper the cooling unit selection for the total required heat rejection from all three components is analytically calculated and thermal management methodology of liquid-cooled Electric Motor is being studied and documented with the help of numerical simulation. The results are further validated with test results in Electric bus for city application.

Improved Air-Flow Distribution through Improved Air Conditioning Vent Design for 3x2 Seating Layout in Buses

With the improvement of standard of living, air conditioning has widely been applied in buses. However, in air conditioning buses air distribution is still needs to be improved, One of the main reasons for this sub-quality comfort is two air flow louvers arrangement for 3x2 layout air conditioner buses. Air conditioning buses hatrack louvers are an integral part in providing comfort to passengers. General trend of the numbers of louvers provided to passengers is two louvers for three seats. Disadvantage of having conventional two louvers is that, there is always one passenger left with no option of directing air towards that person. This lead to an opportunity to design three louvers type hatrack instated of conventional two louvers hatrack, for 3x2 seating layout of buses. This way all three passengers can control the louvers for their own comfort and mass of air flow is sufficient for third passenger as well.
