Underdrive pulleys increase engine output by reducing the draw of the engine's accessories by slowing them down and reducing the horsepower (HP) they use. Horsepower gains from underdrive pulleys can vary by vehicle, engine, number of accessories and the amount of underdrive (improvements of up to 5–15 HP at the wheels have been seen).
An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor , which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Boosting a dead battery through a battery charger can take anywhere from five to twenty minutes depending on the depth-of-discharge (DOD), health of the vehicle battery, and type of engine (engine displacement). AC power is not usually available for a roadside boost. Jump starters are portable battery devices that allow for jump starting of ...
Repeated cycles of partial charging and discharging will increase stratification of the electrolyte, reducing the capacity and performance of the battery because the lack of acid on top limits plate activation. The stratification also promotes corrosion on the upper half of the plates and sulfation at the bottom. [34]
“The automotive suspension system market is poised for steady growth in the coming years, driven by increasing demand for advanced vehicle performance and comfort. As new technologies emerge, particularly in electric and autonomous vehicles, the need for more efficient and adaptable suspension systems will continue to rise.
A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.
Shaft horsepower (shp) is the power delivered to a propeller or turbine shaft. [31] Shaft horsepower is a common rating for turboshaft and turboprop engines, industrial turbines, and some marine applications. Equivalent shaft horsepower (eshp) is sometimes used to rate turboprop engines. It includes the equivalent power derived from residual ...
The LV battery supplies power to the electronics and accessories when the hybrid system is turned off and the high-voltage battery main relay is off. [11] [12] The traction battery is a sealed nickel-metal hydride (NiMH) battery pack. The battery pack of the first generation Toyota Prius consisted of 228 cells packaged in 38 modules, while the ...
