Intelligent engine with micro controller valve actuation and eliminating the cam linkage arrangement

Since the organization of the automobile, the internal combustion engine has evolved considerably even then one constant has remained through out the decade of internal combustion engine development is the camshaft. The camshaft has been used to controlling the valve actuation and timing and therefore influencing the overall performance of the engine. This camshaft rotates relative to the rotation of the crank shaft as the camshaft rotates, cam lobes, attached to the camshaft, interface with the engine´s valves. The inter face may take place via a mechanical linkage, as the result if the cam rotates it forces the valve open. This camshaft will increase the weight of the engine and needs special attention for lubrication, increases the frictional resistance reducing the efficiency of the engine. This paper will discuss about the cam less engine, in this we remove the cam shaft and its linkages. Instead of cam shaft, the valve operation (opening and closing) shall be carried out by electro mechanical poppet valve or electro mechanical ball valve, which is controlled by a micro controller unit, it receives the signal from the sensor fitted inside the crankshaft housing based on the signal micro controller actuate the valve to open or close. By removing the camshaft a drastic increase in engine performance and life and a decrease in fuel consumption can be achieved.
