203 b combustion process and starting aids

what are the 3 factories necasary for combustion in a diesel engine

air quality, fuel quantity and heat

in a given volume of air density is a measurement of the

ocygen concentration

the period of time from when fuel is injected to when it is ignited is called

ignition delay

the factors that affect ignition delay are

injection timing, air tempuature and fuel quality

as altitude and air tempuature increase air will have

decreased density

what is the auto ignition tempauture of diesel fuel

500f-700f

low compression opressures result in

hard starting and white smoke

low sulfur diesel fuels are used to reduce the emesions of

sox

due to the danger of ______emmisions engines must be equiped with a proper exaust system while running indoors

co

black exausht smoke could be a result of

clogged air filter

the formation of smog is a result of

HC,NOX and sunlight

open combustion chamber designs

utilize direct injection

turbulance is needed in an open combustion chamber beacause

the fuel mixes thourougly with the air

precombustion chambers require a glow plug too

pre heat the precombustion chamber

fuel heaters should be controlled by a thermostat beacause

high fuel tempuatures cause a loss in horsepower

4 ways to help a diesel engine start at low ambient temps

heat the intake air, coolant heater,fuel heater,oil heater

starting fluid should not be used in combination engines that have

glow plugs or manifold heaters
