Abstract
The present invention relates generally to a method for providing an efficient and powerful engine for internal combustion four stroke engines using a single valve per cylinder as the intake and exhaust valve. Outside air emerging from an air filter is forcibly pumped into the engine head using a blower which then is drawn into the combustion chamber during the intake stroke. The timing for opening and closure of the single valve is controlled by the camshaft which is provided with a cam lobe profile capable of prolonging the valve timing thus enabling the valve to remain open for a longer duration to cater for evacuation of air in the exhaust stroke and the intake of air in the intake stroke thereby permitting the use of only one single valve per cylinder.
