Parallel Hybrids Of 25 million gasoline-electric hybrids on the world's roads, most are Toyotas —and most of those use the company's classic two-motor power-split parallel hybrid system.
BYD Auto's F3DM sedan is a series-parallel plug-in hybrid automobile, which went on sale in China in 2008. [ 33 ] [ 34 ] [ 35 ] The Two-Mode Hybrid name highlights the drive-train's ability to operate in all-electric (Mode 1, or Input-Split ) as well as hybrid (Mode 2, or Compound-Split ) modes.
In a parallel hydraulic hybrid vehicles, the pump/motor is typically installed between the engine and gearbox, or between the gearbox and differential transmission box. The role of pump/motor is to provide assistance to the engine during acceleration and recapture energy under braking that would otherwise be lost as heat in the conventional brakes.
Honda's older transmissions such as the Hondamatic semi-automatic transmission and its successors use traditional, individual gears on parallel axes like a manual transmission, with each gear ratio engaged by a separate hydraulic clutch pack. This design is also noteworthy because it preserves engine braking by eliminating a sprag between first ...
The Fisker Karma was the first series-hybrid production vehicle. When describing cars, the battery of a series-hybrid is usually charged by being plugged in—but a series-hybrid may also allow for a battery to only act as a buffer (and for regeneration purposes), and for the electric motor's power to be supplied constantly by a supporting engine.
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
The 8HP 70 transmission with the gearset 4 in 23-85-teeth-configuration was the pilot series and therefore without generation designation. It was first used in the BMW 7 Series (F01) 760Li, has a torque handling limit of 700 N⋅m (516 lb⋅ft), and weighs 87 kg (192 lb).
For higher pressures at the outlet, impellers can be connected in series. For higher flow output, impellers can be connected in parallel. A common application of the multistage centrifugal pump is the boiler feedwater pump. For example, a 350 MW unit would require two feedpumps in parallel.
