An engine for a vehicle

Abstract

The present invention provides an engine (100) for a vehicle comprising a plurality of intake valves (108a, 108b, 408a, 408b) configured to allow entry of intake charge into a cylinder (110, 403) of the engine (100); a plurality of exhaust valves (112a, 112b, 410a, 410b) configured to allow exit of the combusted gases from the cylinder (110, 403); at least a camshaft (114, 118, 402) comprising a plurality of intake cam lobes (116a, 116b) fixedly mounted on the intake camshaft (114) and configured to operate at least plurality of intake valves (108, 108b) and a plurality of exhaust cam lobes (120a, 120b) fixedly mounted on the exhaust camshaft (118) and configured to operate at least plurality of exhaust valves (112a, 112b); wherein the number of intake cam lobes (116a, 116b, 404a, 404b) are equivalent to the number of intake valves (108a, 108b, 408a, 408b) and the number of exhaust cam lobes (120a, 120b, 406a, 406b) are equivalent to the number of exhaust valves (112a, 112b, 410a, 410b); wherein the intake cam lobes (116a, 116b, 404a, 404b) operating the intake valves (108a, 108b, 408a, 408b) are relatively at different angles with respect to each other and / or the exhaust cam lobes (120a, 120b, 406a, 406b) operating the exhaust valves (112, 112b, 410a, 410b) are relatively at different angles with respect to each other.
