Laser Ignition and Optical Sensors for Enhanced Combustion
Avinash Malik
Abstract: Sustainability with regard to efficient combustion stands strong on the complete and efficient combustion. Question arises how can we attain that complete efficient combustion first by changing our approach of conventional ignition system of spark ignition so we significantly need breakthrough in our ignition approaches. Laser ignition is promising example in attaining our efficient combustion state. Laser ignition yields extra ordinary advantages compared to the commonly used spark ignition as (1) by minimizing pollution residue (2) overall improve ignition efficiency (3) suitable for lean mixture of bio gas and methane to give enhanced performance (4) flexibility of sequential or multiple ignition which can contribute for enhanced ignition for lean mixture of bio gas, methane. Also by attaching optical sensors gives correct spot for incomplete combustion and gives enhanced efficiency These two factors can be deciding factors in achieving overall enhanced efficiency of combustion and can be breakthrough in combustion process. As these two encompass the shot comings of conventional spark plug, restricted position. In this research paper we will discuss the enhanced efficiency of combustion process. Laser ignition and optical sensors seems promisable in attaining the enhanced efficiency of combustion engine. Laser plasma ignition and optical sensors holds strong point in achieving. Laser plasma ignition helps to burn lean mixture efficiently and gives enhance efficiency. Types are listed as (1) Thermal initiation (2) Non resonant Breakdown (3) Photo chemical ignition. By far non resonant is conventional to use for laser ignition gives freedom to selecting wavelength in ease of implementation. Absorption optical sensors are investigated as they are helpful in providing precise feedback to optimize combustion process and helpful in pollution control. Hence previous research discusses following types of sensors (1) Wavelength multiplexed TDL sensors (2) Diode laser senso
