Bernoulli's principle
|
Bernoulli's principle states that in fluid flow, an increase in velocity occurs simultaneously with decrease in pressure.
|
Carbon monoxide
|
Is a major product of the incomplete combustion of carbon and carbon-containing compounds.
|
Oxygen
|
At standard temperature and pressure, oxygen is predominantly found as a gas consisting of a diatomic molecule with the chemical formula O2.
|
Venturi
|
Are found in many applications where the speed of the fluid is important, and form the basis of devices like a carburetor.
|
Volumetric efficiency
|
Volumetric efficiency is a measure of the air-fuel mixture burned in the cylinder, usually expressed as a percentage.
|
Thermal expansion
|
Thermal expansion refers to the way some materials expand when they are heated.
|
Frequency
|
Sound travels through the air by producing pressure waves - areas of high pressure and areas of low pressure. The rate at which these waves reach our ears is called frequency.
|
Back-pressure
|
Back-pressure in an exhaust system refers to a build-up of pressure in the system that interferes with the outward flow of exhaust gases.
|
Stoichiometric ratio
|
Stoichiometric ratio is the air-fuel ratio necessary for complete combustion.
|
Pressure & vacuum
|
As air pressure is reduced, a vehicle has to reduce the amount of fuel delivered to the engine to maintain the correct air-fuel ratio.
|
Air density
|
The density of air is its mass per unit volume.
|
Tachometric relay
|
The tachometer indicates engine RPM.
|
Potentiometer
|
A potentiometer is a mechanically variable resistor.
|
| Closed loop |
A closed loop is part of a feedback system that collects information on how a system is operating & feeds that information back to affect how the system is working. |
