Can faulty injectors cause knocking?
No.... A knock is generally caused by the ignition timing. An injector stuck shut causes a lean misfire which causes the engine to hesitate and loose power but not knock. An injector stuck open causes a rich mixture which will either reduce the chances of a knock or once again cause a misfire. via
How diesel knock affects engine performance?
Unlike spark-ignition knock, diesel knock occurs when injected fuel auto-ignites and combusts in the premixed stage of combustion. Whilst this process is a normal part of diesel engine operation, various circumstances can lead to excess quantities of fuel combusting in a premixed fashion. via
