ABSTRACT:
A heat protecting sleeve or bushing surrounds the terminal end of the fuel injection plug and is formed with an inturned, inwardly directed lip which resiliently bears against the end face surface of the fuel injection plug, in a slightly funnel-shaped arrangement to permit tightening of the plug within the respective matching bore opening of the cylinder head while compensating for tolerances in manufacture, and yet provide for resilient sealing engagement of the inwardly directed funnel-shaped flange forming the sealing lip against the end face surface of the plug.
