The proposed delayed entry valve (1) is provided for supplying delay entry of hydrogen in multi cylinder reciprocating type engines. The proposed delayed entry valve (1) mainly comprises of inner cylinder (2), outer cylinder (3), upper cap (4), lower cap (5), hydrogen supply hole (6a), (6b), (6c) and (6d), water inlet (9) and water outlet (10). The said hydrogen supply hole (6a), (6b), (6c) and (6d) are provided on outer surface of outer cylinder (3) which are connected to four cylinders of engine for supplying hydrogen to the four respective cylinders of engine. The present delayed entry valve (1) one after other discharges the hydrogen gas from the hydrogen supply hole (6a), (6b), (6c) and (6d) to the respectively connected cylinders only between specific degrees from TDC to BDC of crank rotation in suction stroke, delaying the entry of hydrogen gas to each cylinder.
