2. Sea foam - Wikipedia

   en.wikipedia.org/wiki/Sea_foam

   Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

3. Wide open throttle - Wikipedia

   en.wikipedia.org/wiki/Wide_open_throttle

   Wide open throttle or wide-open throttle (WOT), also called full throttle, is the fully opened state of a throttle on an engine (internal combustion engine or steam engine). The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate/butterfly valve.

4. Buoyancy engine - Wikipedia

   en.wikipedia.org/wiki/Buoyancy_engine

   Diagram of how a Buoyancy Engine works. A buoyancy engine is a device that alters the buoyancy of a vehicle or object in order to either move it vertically, as in the case of underwater profiling floats and stealth buoys, or provide forward motion (therefore providing variable-buoyancy propulsion) such as with underwater gliders and some autonomous aircraft.

5. Break-in (mechanical run-in) - Wikipedia

   en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

   Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...

6. Naturally aspirated engine - Wikipedia

   en.wikipedia.org/wiki/Naturally_aspirated_engine

   Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...

7. Lean-burn - Wikipedia

   en.wikipedia.org/wiki/Lean-burn

   From 1976 through 1989, Chrysler equipped many vehicles with their Electronic Lean-Burn (ELB) system, which consisted of a spark control computer and various sensors and transducers. The computer adjusted spark timing based on manifold vacuum, engine speed, engine temperature, throttle position over time, and incoming air temperature.

8. Components of jet engines - Wikipedia

   en.wikipedia.org/wiki/Components_of_jet_engines

   The components above, except the shaft, are linked by a parameter common to all of them, the flow rate of gas passing through the engine which is the same for all components at the same time (as a basic statement this is an acceptable approximation which ignores the addition of fuel in the combustor and bleeding air from the compressor).

9. Magnetohydrodynamic drive - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_drive

   Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.
