Dismantling of a Modern Vehicle & Study of a VVT-i Engine

When we were to choose a topic among various options we chose to work on something related to automobiles - a diverse area of mechanical engineering. In order to work & study on the engine of the given car (1999 Toyota Echo Sedan) we had to dismantle the car first. Then we had to dismantle the engine. The engine - a 2NZ-FE engine is a VVT-i (Variable Valve Timing with Intelligence) engine. Afterwards we had to make a cut-model of the engine by cutting various dismantled parts & assembling the cut parts. Finally we re-assembled the given car without the engine. In the process we gained a lot of practical knowledge about the VVT-i engine parts. The cut-model we made can be utilized further in future to educate students. Future thesis students can also work with it by adding up transmission system cooling system air-conditioning system lubrications system etc. Mechatronics devices can also be added up to give autonomous programming such as – self-drive avoiding obstacles or follow leading car etc.
