part in the vehicle manufacturing industry and, also main source of income to the business. Currently, Internal Combustion Engine maintenance can be termed as the most crucial part in vehicle modernization and the valve lapping process which is put in this research which is done all through IC engine maintenance. The present-day techniques utilized in most automobile organizations for valve lapping are not productive and spend a lot of operating hours. 'Valve lapping Machine’ for Internal Combustion Engine, is a tool which is mapped out to vanquish these problems through minimizing/reducing the human interference during the process. The research includes the report of designing the device, methodologies that are utilized, results received by using facts & analysis so, that we can enhance the design and design of the valve lapping system. Lapping is a machining mechanism wherein, two surfaces are rubbed together with an abrasive among them, via hand motion or using a system. This can take two forms, the first form of lapping (traditionally called grinding), involves rubbing a brittle material which includes glass towards a floor along with iron or glass itself (also called the "lap" or grinding tool) with an abrasive along with aluminum oxide, optician's rouge, silicon carbide, etc., in between them.
The thought of inventing a system for the valve lapping system came to us, while we studied that the conventional method used for valve cleaning are not green and additionally time consuming. Engine head polishing and sustenance procedure plays an important role for proper working of engine. The system of valve cleansing approximately takes 1 hour to complete inclusive of testing of the valve seat highquality using petrol. As, the conventional procedure is executed by employing a valve lapping stick, it is very tough and not much efficient. This led us to think how beneficial it could be if there can be a gadget that has a higher overall performance over conventional technique for valve lapping.

1. INTRODUCTION: The approach of valve lapping is put into effect to obtain the flawless seat of valve in valve sitting area. Valve lapping or the manner of creating a seat in allying valves of engine & the interrelated valve-seat area within the IC (internal combustion) engine head (cylinder head) is a piece of work which requires to be achieved very perfectly. The significance of obtaining a correct seat is that the air/fuel mixture (in petrol engines) or air (in diesel engines) is restricted from flowing into the combustion chamber, as the exhaust fuel is avoided from flowing to the exhaust manifold from the combustion chamber till the proper time. And, also a seat prevents condensation leaks. This system of valve lapping is usually concluded with the usage of a valve lapping stick or an energy tool. As, both tools are not very robust, those tools may be replaced with the help of the 'Valve Lapping Machine
