2. Spark plug - Wikipedia

   en.wikipedia.org/wiki/Spark_plug

   Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...

3. Sodium–sulfur battery - Wikipedia

   en.wikipedia.org/wiki/Sodium–sulfur_battery

   Cut-away schematic diagram of a sodium–sulfur battery. A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. [1] [2] This type of battery has a similar energy density to lithium-ion batteries, [3] and is fabricated from inexpensive and low-toxicity materials.

4. Operating temperature - Wikipedia

   en.wikipedia.org/wiki/Operating_temperature

   An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...

5. Heat capacity ratio - Wikipedia

   The heat capacity ratio is ... The above value of 1.4 is highly consistent with the measured adiabatic indices for dry air within a temperature range of 0–200 °C ...

6. Solid-state battery - Wikipedia

   en.wikipedia.org/wiki/Solid-state_battery

   This battery has a long life and heat resistance. Production of 200 mmAh cylindrical solid-state batteries was to begin in January 2024. Size: diameter 23 mm/height 27 mm. [44] In September 2023, Panasonic unveiled a solid-state battery for drones. It can be charged from 10% to 80% in 3 minutes and lasts for 10,000 to 100,000 cycles at 25 °C.

7. Exhaust heat recovery system - Wikipedia

   en.wikipedia.org/wiki/Exhaust_heat_recovery_system

   An exhaust heat recovery system turns waste heat energy in exhaust gases into electric energy for batteries or mechanical energy reintroduced on the crankshaft. The technology is of increasing interest as car and heavy-duty vehicle manufacturers continue to increase efficiency, saving fuel and reducing emissions.

8. Electric stove - Wikipedia

   en.wikipedia.org/wiki/Electric_stove

   An electric stove uses electricity to provide heat. An electric stove , electric cooker or electric range is a stove with an integrated electrical heating device to cook and bake . Electric stoves became popular as replacements for solid-fuel (wood or coal) stoves which required more labor to operate and maintain.

9. Turbulent Prandtl number - Wikipedia

   en.wikipedia.org/wiki/Turbulent_Prandtl_number

   It is useful for solving the heat transfer problem of turbulent boundary layer flows. The simplest model for Pr t is the Reynolds analogy, which yields a turbulent Prandtl number of 1. From experimental data, Pr t has an average value of 0.85, but ranges from 0.7 to 0.9 depending on the Prandtl number of the fluid in question.
