I believe the primary combustion of air in a standard recriprocating engine is the initial burn of fuel/air in the piston. As the exhaust gases leave the engine, vehicles equiped with EGR (exhaust gas recirculation) have sensors to detect quality of combustion byproducts and feed exhaust back into the piston. This is a second burn.

What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
Is the transformer's iron core called the primary?
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
Is it OK to convert your high efficiency furnace from its now inside air intake to start getting the intake air from the outside?
Yes, most if not all 90+ efficient furnaces are designed to take primary or combustion air from outdoors. That is partly where they get their high efficiency rating from. They are not using air that has already been heated for combustion.
Why transformar primary refers to secondary?
All transformers contain both primary and secondary coils. The primary will refer to the secondary when the voltage is to high. As voltage increases, it passes down the power to the secondary for efficient distribution of power.
When can be current in a primary coil induce a current in a secondary coil?
Secondary current = Primary current *(Number of secondary turns /Number of primary) turnsAnswerA current isn't 'induced' into the secondary winding of a transformer. It's a voltage that is induced into the secondary winding.Provided the secondary winding is connected to a load, the secondary voltage then supplies a secondary current which is determined from (Is = Vs/Rload). The primary current then depends upon the value of the secondary current and the turns ratio.
Is secondary pollutants more harmful than primary pollutants?
Primary air pollutants are emitted directly into atmosphere from a process such as exhaust from a engine, industries, volcanic eruption Secondary air pollution are formed in the air when primary pollutants interact.
What is the difference between secondary and primary pollutants?
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
Where to install air separator in primary circuit of variable primary and secondary chilled water air conditioning systems?
If you have a primary /secondary, the chilled water should be constant at the primary loop. The secondary can be variable. The air seperator is always connected at the return water side and is most likely very effective at the primary return. However is a must as well on the return side of the secondary.
Why do semi trucks have two air tanks?
You have a primary and secondary tank. Certain air functions of the truck use the primary and others use the secondary tank.
What the difference between primary and secondary pollutants?
Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant
Is Nitrogen oxide a primary or secondary pollutant?
secondary pollutant. deals with oxygen in air
Where does the secondary bronchi supply air to?
there are two primary bronchi which branch off into secondary bronchi which supply air to the lobes of the lungs
Why continuous purging is required and point out some applications where it is required?
In thermal power plant for proper combustion we are using the air which is taken from atmosphere through forced draft fan and primary air fan .FD fan is also known as secondary air fan. Primary air and secondary air both are pre-heated before sending into boiler. In thermal power plant for preheating the air, APH (air pre heater) is used, which raises the temperature of air from 27 deg -45 deg to 220-250 deg. Primary air is used to carry the pulverized coal from pulverizer to boiler. APH at Lanco is tri sector type i.e. sectors for 1) primary air 2) secondary air 3) flue gas. Due to improper sealing of APH, mixing of gases takes place. Since the three gases are at different pressure hence mixing takes place accordingly i.e. higher pressure to Lower pressure side. Primary air is at maximum pressure so it mixes towards flue gas & secondary air. Secondary air pressure is greater than that of flue gas hence again secondary air mixes with flue gas. So we can se that chance of mixing of flue gas with Primary & secondary air is very less but the ash particles in the flue gas gets stuck to the plates of air preheater & gets mixed with primary & secondary air path, on rotation of APH. When we measure the primary air and secondary air flow through Varabar (flow element), this ash gets deposited in varabar. Due to this reason our flow measurement is not correct that is very dangerous for our power production. For proper running the boiler total air flow should always be greater than 30%. If air flow is less than 30%, boiler will be tripped & simultaneously Turbine & generator will also be tripped i.e. power production is stopped.
On the air brake system of a semitruck with pull trailer does the air pressure maintain itself if the petcock on the wet tank is fully opened?
Yes, you still have your primary and secondary air tank.
How many air tanks on international day cab tractor?
Day cab or not, there'll be a primary air tank, and a secondary air tank.
Difference between primary server and secondary server?
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
What is primary and secondary victim?
primary: Raul Secondary: Julie
