The Toyota Sequoia is a full-size SUV manufactured by Toyota mainly for the North American market since 2000 for the 2001 model year, being derived from the Tundra pickup truck. It is the second largest SUV ever produced under the Toyota brand, after the Japan-exclusive, military-focused Mega Cruiser .
Thermal emittance or thermal emissivity is the ratio of the radiant emittance of heat of a specific object or surface to that of a standard black body.Emissivity and emittivity are both dimensionless quantities given in the range of 0 to 1, representing the comparative/relative emittance with respect to a blackbody operating in similar conditions, but emissivity refers to a material property ...
Another way to modify the object thermal emission spectrum is by reducing the dimensionality of the emitter itself. [28] This approach builds upon the concept of confining electrons in quantum wells, wires and dots, and tailors thermal emission by engineering confined photon states in two- and three-dimensional potential traps, including wells ...

Conversely, a low-e material such as aluminum foil has a thermal emissivity/absorptance value of 0.03 and as an opaque material, the thermal reflectance value must be 1.0 - 0.03 =0.97, meaning it reflects 97 percent of radiant thermal energy. Low-emissivity building materials include window glass manufactured with metal-oxide coatings as well ...
zero evaporative emissions from its fuel system a 15-year (or at least 150,000 mile) warranty on the emissions system and meet SULEV tailpipe emission standards.
As the object increases in temperature to about 500 °C (773 K; 932 °F), the emission spectrum gets stronger and extends into the human visual range, and the object appears dull red. As its temperature increases further, it emits more and more orange, yellow, green, and then blue light (and ultimately beyond violet, ultraviolet ).
Toyota have been using it to replace the naturally-aspirated 2GR-FKS V6, offering more peak torque at lower speeds and improved fuel consumption and emissions with the turbo engine. [15] There also are two distinct hybrid variants which carry the same T24A-FTS engine designation as the regular (non-hybrid) variant.
