Car abruptly stopped on road , when it finally stRted again with new battery. The motor started knocking

Hello, the battery - or need of a battery - did not have any influence in the noise you are hearing. The noise does sound like a possible internal engine noise...due to something failing internally. You should not drive the vehicle further until you have the concern assessed. Seek local guidance at a shop near you. Use this link to find one: www.repairpal.com/repair-shops
