The EFI system saw the introduction of knock control. It is turbocharged by a Toyota CT20 Turbo (the same unit as used in the 2L-T diesel) to generate 160 PS (118 kW; 158 hp) at 6,000 rpm and 206 N⋅m (152 lb⋅ft) at 4,800 rpm. This was the first turbocharged twin-cam engine built in Japan.
Interior view of a turbomolecular pump. A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [1] [2] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface.
Factory service manuals (FSM) are the manuals provided by manufacturers which cover the servicing, maintenance, and repair of their products. They are not designed for the general public, however they are created by manufacturers for use at their OEM dealerships.
Torr-Seal, or its generic equivalent Hysol-1C (US brand name) or Loctite 9492 (EU brand name), is an epoxy with resin and hardener for use in vacuum environments. It will begin to degrade at high temperatures but otherwise is very stable with very little outgassing. Other vacuum-rated epoxies are also available.
Hitachi Construction Machinery Co., Ltd. was established in 1970, and was involved in the production of Japan's first mechanical excavator.The company has now become a major construction equipment manufacturer in the world, and it is listed on the Nikkei 225.
Cryogenic seals provide a mechanical containment mechanism for materials held at cryogenic temperatures, such as cryogenic fluids. Various techniques, including soldering and welding are available for creating seals; however, specialized materials and processes are necessary to hermetically entrap cryogenic constituents under vacuum-tight conditions.
An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
A roughing pump is any vacuum pump (typically mechanical) used to initially evacuate a vacuum system, as a first stage towards achieving high vacuum or ultra high vacuum.The term "roughing pump" derives from the vacuum range it works in, "rough vacuum", above 1x10 −3 torr (0.1 Pa).
