Retrofitting of Internal Combustion Engine Vehicles with DC Motor

This article gives a detailed report on the retrofitting of an IC engine vehicle with a specially designed DC motor. The emission losses of an old ICE vehicle increase and saturates to its highest value at around this time. The load and rpm analysis of ICE shows that the available usable torque to produce the desired RPM is in a very small range and thus replacing such engines with electric engines which have high torque to speed ratio will increase the performance of the vehicle greatly. The DC motor used in this application has been specially designed for the vehicle. The Total Tractive Effort (TTE) is calculated considering the curb weight of the chassis and then eliminating the components which are specific to the ICE such as engine and fuel tank. Other factors such as the static and dynamic friction, rolling resistances and other constants have been considered taking into account the road safety, road transportation and NHAI standards. The retrofitted vehicle has a curb weight less than that of the ICE counterpart. The high torque DC motor gives better acceleration and the high RPM provides better maximum speeds. The main goal is to have a used ICE vehicle and to completely renew it with a DC motor. This would eliminate the use of non-renewable fuels while also extending the life of the vehicle.
