SUMMARY
Large fuel droplets greater than 100 micrometers in size behave differently in a spark-ignition (SI) engine cylinder. During the exhaust up-stroke, the piston can break these droplets into smaller ones, while during the compression stroke, the increased pressure likely causes the droplets to adhere to the piston. The turbulence within the cylinder prevents the droplets from sticking to the cylinder walls, influencing fuel atomization and combustion efficiency.
