Need help with flexible engine assembly

Hello everyone outhere. Newbie here, I'm senthuran, I'm a 3rd year B.Tech Mechanical Engineering student at Dr.M.G.R university in chennai south India. My project comes up in my 8th semester. I underwent a 15 day inplant training at BMW assembly plant in chennai. I spoke to a few people there about a suitable title for my project. They asked me what i'm interested in, I told them that i'm interested in engine assembly and sensors. They told me that flexible engine assembly is a very good title. Production Technology of Flexible Engine Assembly is a very challenging topic. I tried to google it but i couldn't find anything good. So I request someone here who is well experienced to explain me about this because it would be of very great help for my studies...Thank u very much in advance
