The present subject matter provides an internal combustion engine (101) for a vehicle (100). The internal combustion engine includes at least one cylinder head (203). The at least one cylinder head includes at least one intake port (301). A combustion chamber for receiving intake charge from a fuel supply device through at least one intake port is provided. At least one exhaust port (304), which 5 is capable of expelling combusted gases from the combustion chamber to atmosphere through an exhaust pipe (200) of vehicle, is provided. The at least one exhaust port has an upstream portion (310) adjoining the combustion chamber and a downstream portion (307) adjoining an inlet opening (201) of the exhaust pipe. The downstream portion of the exhaust port has a first cross-sectional area (APT) 10 substantially equal to or substantially lesser than a second cross-sectional area (APE) of the inlet opening of the exhaust pipe.
