Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

The 361 cu in B engine also introduced in 1958 was essentially the same as the 350 except with a larger 4 + 1 ⁄ 8 in (105 mm; 4.12 in) bore, for an actual displacement of 360.83 cu in (5,913 cc). In 1962, the Dodge Polara 500 came standard with a 305 bhp (227 kW) version of the 361 that had a four-barrel carburetor , dual-point distributor ...
The 361-cubic-inch (5.9 L) 361 was released in 1939 alongside the 426 and 451. The 361 was discontinued in 1949 and replaced by the 360 "Group 2" engine. The 360 and 361 shared the exact same 4 + 1 ⁄ 8 inches (100 mm) bore and 4 + 1 ⁄ 2 inches (110 mm) stroke, but the 361 used the larger "Group 3" block. It produced a maximum 136 hp @ 3000 ...
U.S. stocks tumbled to one of their worst days of the year after the Federal Reserve hinted Wednesday it may deliver fewer shots of adrenaline for the U.S. economy in 2025 than earlier thought.
This is primarily a factor in multi-cylinder engines. Engine width can be excessive for even two cylinder engines of certain designs. Rotary disk valve engines with wide sweeping transfers can be so wide as to be impractical as a parallel twin. The V-twin and fore-and-aft engine designs are used to control overall width.
Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
