A torque converter cannot achieve 100 percent coupling efficiency. The classic three element torque converter has an efficiency curve that resembles ∩: zero efficiency at stall, generally increasing efficiency during the acceleration phase and low efficiency in the coupling phase.
Idle creep, sometimes called idle speed or just creep [citation needed] is the default speed that a vehicle with an automatic transmission will move either forward or in reverse when the change lever is in D for drive or R for reverse and the foot is taken off the brake pedal but the accelerator pedal is not depressed.
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft.
Constantinesco automobile advertisement. The Constantinesco was a Romanian automobile produced from 1926 to 1928. It was built by George Constantinescu, a Romanian-born engineer and inventor, who had gained fame by his invention of an improved version of a machine gun synchronization gear (a device allowing aircraft-mounted machine guns to fire through the propeller without striking the blades ...
Despite having to meet emission regulations, the engine was able to increase horsepower ratings to 350 hp (261 kW) and torque to 650 lb⋅ft (881 N⋅m) at the flywheel. Horsepower and torque are achieved at 3,000 rpm and 2,000 rpm respectively. It also features a compound VGT turbo system. Air enters the low-pressure turbo (the larger of the ...
While the engine was under development in May 1960, Huebner said that it would serve as its own torque converter, generate 140 horsepower (100 kW), have an acceleration lag of 1.5 seconds (compared with nine seconds for its predecessor), and weighed 150–450 lb (68–204 kg) less than a comparably sized piston engine.
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
