EFFECTS OF FUEL PROPERTIES AND SPRAYING FLUID ON GASOLINE ENGINES

Abstract

In this study, the ignition delay measurement determined numerically by using some practical equations. Outboard ignition engines take the fuel-air mixture into the cylinder and compress it. High compression ratio is an important parameter that increases engine efficiency. The compression ratio is kept away from the knock limit, which is also defined by self-ignition of the mixture. The ignition system should be able to initiate combustion without igniting the mixture at the appropriate moment and causing undesired mechanical and thermal stresses. The temperature at the tip of the spark plug at the time of ignition is proportional to the blur of the gauge voltage and usually ranges from 500-800 ^oC. A well-working flue gas should have a porcelain temperature of less than 500 ^oC and no more than 850 ^oC. The temperature at the end of the isolator is crucial for the development of ignition and combustion. Higher tip temperatures, premature ignition, and low temperatures cause spark plug contamination and kicking. Accumulation of unburned or slightly burnt hydrocarbons in the interior of the buoy is indicated as the responsibility of the contamination and therefore the singlet. Hydrocarbon deposits reduce electrical insulation too much over time, preventing the syringe from forming between spark plug nails. In our work, evaluations were made on hydrocarbon deposits in terms of insulator temperature and system self-cleaning temperature and so on.
