SUCTION STROKE

All about engine/ his also called intak stroke or injection stroke and charging stroke. And the suction stroke will done when the piston come t.d.c to b.d.c and during this the inlet valve get open.so the air and fuels mixture comes inside of cylinder as soon as open the inlet valve.but in this time the pressure inside of cylinder is less than atmosphere. So therefore the piston pulls air from carburetor's by 120 to 140 ft.second speed.and while coming the air and fuels mixture inside of cylinder from carburetor's at this time the air pressure become (6)to (8) pound inside of cylinder. And during this the crankshaft does complete half round. See you in next time
