INTERNAL COMBUSTION ENGINE IGNITION PLUG

摘要

An combustion initiation plug for an internal combustion engine comprises an electrical connector for connection to an electrical current source and a body supporting a combustion initiator that operates when an electrical current passes through the electrical connector. The body comprises a passage radially extending from a portion of the combustion initiator which is internal to the plug. The plug further comprises an intake for receiving a combustion enhancer. The intake leads through a hollow chamber in the body and the passage to an opening into the combustion chamber to supply the combustion enhancer into the combustion chamber. A one-way valve or solenoid allows the combustion enhancer to flow through the hollow chamber into the passage, but prevents flow in the other direction.
