Optimization mechanism applicable to abnormal combustion techniques for Hydrogen-fuelled Internal Combustion Engines

Hydrogen Internal Combustion Engines are being reckoned to meet the challenges as environment-friendly vehicles, for the development of novel Internal Combustion (I.C) engines in controlling injection during the performance of vehicles. One among the challenges faced in the development of hydrogen I.C. engines, the foremost is the technology to establish abnormal combustion conditions. This enforces several experimental measures which are underway to assess, reduce and control the abnormal combustion conditions like surface ignition, pre-ignition, backfire and engine `knock´. However, these results do not guarantee the complete elimination of prevailed unwarranted auto-ignition occurrences. The basic research concepts studied are to detect an abnormal combustion, at the initial stages and cut off the fuel supply to the engine to prevent any damage or hazard. A typical sensor is attached to the spark-ignition of the engine, which sends a signal to the Engine Control Unit whenever the vehicle is started. Induction of a piezoelectric sensor senses the start of combustion and sends the signal to the Control Unit. The Control system receives and compares both the signals confirming the status of normal functioning of combustion. If the Control Unit detects, and monitors, identifying the presence of an abnormal combustion, by sending a signal to the actuators to stop the fuel supply to the engine, quenching the abnormal combustion in hydrogen I.C. engine. This paper supplements a critical, an innovative, concept on the design of Control Unit under abnormal combustion conditions.
