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 ...
Rotary engines produce a lot of heat, and the RE5 had water- and oil-cooling, and double-skinned exhaust pipes. Ignition was CDI, with two sets of ignition points actuated via vacuum and rpm sensors, to light a solitary NGK spark plug. [15] Three oil reservoirs served the sump, gearbox and total loss tank.

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.
The working gas pressure drops instantaneously from point 4 to point 1 during a constant volume process as heat is removed to an idealized external sink that is brought into contact with the cylinder head. In modern internal combustion engines, the heat-sink may be surrounding air (for low powered engines), or a circulating fluid, such as coolant.
Temperature vs. heat load diagram of hot stream (H 2 O entering at 20 bar, 473.15 K, and 4 kg/s) and cold stream (R-11 entering at 18 bar, 303.15 K, and 5 kg/s) in a counter-flow heat exchanger. "Pinch" is the point of closest approach between the hot and cold streams in the T vs. H diagram.
Beyoncé is now the most RIAA certified female artist of all time with 103 certified titles across her discography, the Recording Industry Association of America (RIAA) announced Tuesday. “We ...
The diagram was created in 1904, when Richard Mollier plotted the total heat [4] H against entropy S. [5] [1]At the 1923 Thermodynamics Conference held in Los Angeles it was decided to name, in his honor, as a "Mollier diagram" any thermodynamic diagram using the enthalpy as one of its axes.
“While a week-long vacation for a party of two, including 3- to 4-star hotels, taxis, museum entry, some light touring and meals would typically cost a minimum of about $4,500, travelers could ...
