preignition meaning in Hindi

Examples

1. This is called preignition, detonation or knock and can cause severe engine damage.
2. Commercial flash pots include safety features such as warning pilot lamps, preignition grounding, and safing circuits.
3. Diesel engines do not have preignition problems because fuel is injected at the end of the compression stroke, therefore higher compression is used.
4. This prevents the combustion from initiating in an uncontrolled manner or in unburnt residues ( engine knocking ) or premature ignition ( preignition ).
5. Finally, natural gas is not the same everywhere in the country, and the differences in the mixture between methane and butane can cause preignition, or knocking.
6. This included the ESC ( Electronic Spark Control ) distributor and controller borrowed from the 301 Turbo, which allowed for higher timing without the penalty of engine damaging pinging or preignition.
7. To ignite, the fuel must have a low flash point, but in order to avoid preignition caused by residual heat in a hot combustion chamber, the fuel must have a high autoignition temperature.
8. The hot bulb engines used in preignition in a conventional spark-ignition engine and leads to uneven forces and high thermal and physical stresses on the engine's internal parts, especially the piston.
9. Ideas such as water injection ( to reduce preignition ) and the " hot tube " engine ( which allowed the volume of the vaporiser to be altered with engine speed, thus changing the overall compression ratio ) added complexity and cost and still could not provide power-to-weight ratios in the same league as the rapidly developing diesel engine.
10. The Southwest Research Institute ( SwRI ) launched the two-year Preignition Prevention Program ( P3 ) consortium in 2011 aimed at understanding the source of LSPI and working towards developing a standardized test for lubes / fuels The consortium's objectives included examining the interaction between fuel and oil in LSPI events, understanding how hardware design could be used to help mitigate LSPI, and identifying fluids that can help reduce LSPI occurrences.
