Steam engine
* Every steam engine has a boiler
  - needs a boiler to make steam from water
* Most steam engines are black and they blend in
  - part of steamers
* Most steam engines have energy
  - potential energy
  - produce power
* Most steam engines use energy
  - pistons
* are among the most brilliant discoveries by mankind.
* are part of America s history
  - steam locomotives
  - very common
* become larger and carry higher pressure.
* is the fundamental technological advance of the Industrial Revolution.
* rely on boilers to store steam at a pressure necessary to operate the engine.

Inference engine
* are also capable of modeling complex problems involving thousands of rules.
* implement atomic rules and RETE processing algorithms.
* is the software that embodies the strategy used to search through the rule base.

Internal combustion engine
* burn fossil fuel
* convert chemical energy
* convert potential chemical energy
* have cylinders.
* use petroleum products

Ion engine
* Most ion engines have low power
* is an engine
* work on the principles of charged particles.

Jet engine
* All jet engines have a combustor or burner in which the air and fuel are mixed and burned
  - compressor to increase the pressure of the incoming air
  - nozzle which produces the thrust as described on the thrust equation slide
  - turbine to drive the compressor
* Most jet engines are part of jets.
* are aircraft engines

Ramjet
* are a favorite of sci-fi authors
  - basically a hollow tube with no moving parts, resolving the temperature problem
  - jets without moving parts, burning cheap fuel like paraffin oil
  - only effective at high velocity when they are drawing oxygen on board
* jet engine

Rocket engine
* Many rocket engines are very small.
* Most rocket engines are chemical engines.
* Some rocket engines are part of missiles
  - rockets
  - burn liquid fuels while some burn solid fuels
* are engines
  - explosive devices, and an unstable rocket makes a dangerous projectile
* are reaction engines , obtaining thrust in accordance with Newton's third law
  - therefore necessary for operation in the outer atmosphere and space
* create the most intense noise.
* employ the principle of jet propulsion.
* have their own peculiar labeling system
  - to carry their own oxidizer
* operate at very high pressures and can cause great damage if they are to explode.
* provide forces.
* use oxygen in many ways.
* vary in size and functionality depending upon the mission.
+ Rocket engine, Liquids, Solids and Hybrids: Rockets

Turbojet engine
* are used on airplanes.
* have a gas compressor at the front that takes in air.
+ Jet engine: Motors
  * Turbojet engines are used on airplanes. Turbojet engines have a gas compressor at the front that takes in air. The engine burns fuel to make the air expand, and it blows a big wind out the back.

Marine engine
* Many marine engines sit very low in the bilge and water is consistently in contact with the oil pan.
* operate on dirty fuels.

Modern engine
* Many modern engines have control systems that keep the engine from knocking.
* Most modern engines have what are called overhead cams.
* use high degrees of compression.
+ Octane rating: Chemistry :: Everyday life
  * Modern engines use high degrees of compression. They therefore need fuel that does not detonate easily. Such fuel has a higher octane rating. The rating is done by comparing the fuel to the mixture of iso-octane and heptane that would detonate in the same way. Such a mixture of 90 percent iso-octane and 10 percent heptane has an octane rating of 90. Gas is available with lower octane ratings in the US than in Europe.

Steam locomotive
* achieve their greatest horsepower at high speeds.
* are locomotives
