less fuel will enter the cylinder lower will be cylinder compression temperatures more complete will be fuel combustion more rapid will be the rise in combustion pressure
blows out the exhaust gases supplies oxygen for combustion cools the valves and cylinder walls all of the above
a shortened ignition delay period a lean fuel/air mixture excess fuel in the combustion chamber rapid vaporization of injected fuel droplets
air bottle air compressor crank case combustion chamber
lubricant coolant combustion product second refrigerant
high compression pressure low intake air temperature low exhaust pressure high scavenge air pressure
clogged filters poor combustion overloading of the diesel shock of fuel lines
cylinder valves compression rings piston skirts oil rings
expansion of the combustion gases exhaust and intake valves just closing maximum compression is just being attained fuel injection occurring at that point and combustion begins
water in the fuel insufficient fuel for combustion clogged air intake passages burning lubricating oil
cam followers push rods combustion gases valve springs
Atomization Metering Effective stroke Penetration
turbine engine gas turbine steam engine internal combustion engine
delivering more air into the cylinder than it would normally receive during an ordinarycharging process forcing the products of combustion out of the cylinder with the fresh air charge collecting the air charge at the cleaner combustion and expansion of hot gas
fouling turbine fuel pump faults lubrication failure excessive cooling
affect the injection pressure improve combustion reduce compression pressure decrease power output
Combustion does not begin until the piston starts down on the power stroke Maximum combustion pressure is reached before TDC Turbulence in the cylinder causes a delay in ignition Maximum cylinder firing pressure is not developed until the piston passes TDC
