HICAS
HICAS (; High Capacity Actively Controlled Steering) is Nissan's rear wheel steering system which was fitted to cars from approximately 1985 to 2010, including models ranging from the Skyline (R31, R32, R33, and R34) and Fairlady Z (Z32) to smaller vehicles like the Nissan Cefiro (A31), Silvia (S13 & S15)/ 240SX/180SX and Nissan Serena/ Nissan Largo.

Unlike many other four wheel steering systems, HICAS and Super HICAS are fitted to improve handling rather than just as a parking aid. Disabling or removing HICAS has become a popular aftermarket modification, with proponents citing more predictable steering behavior as an advantage. However, after disabling HICAS, it has been noted that slow maneuvers including parking and quick response steering seemed more difficult. Versions The versions are distinguished by the degree of rear steering and actuator for the rear steering rack, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Q-car
A sleeper (American English) or Q-car (British English) is a car that boasts high performance while having an unassuming exterior. Sleepers are usually developed on the platform of a non-athletic class of vehicle, most often that of an economy car. The American name for this type of vehicle comes from the term sleeper agent, whereas the British name is derived from the Q-ships used by the Royal Navy. The British term has been in use since the aftermath of World War II. In the February 1963 issue of ''Motor Sport'' magazine, British journalist Bill Boddy states: "the modifications carried out by Lotus have turned the Lotus Cortina into a 'Q' car par excellence" in a highlight of the high-performance Cortina's unassuming exterior. Likewise, in the 1956 British film '' The Long Arm'' (known as ''The Third Key'' in the United States), the term is used in reference to unmarked police cars patrolling the city of London by night, indicating that it was in use among British law en ...

Multi-link Suspension
A multi-link suspension is a type of independent vehicle suspension having three or more control links per wheel. These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 and later on their W201 and W124 series. Typically each arm has a spherical joint (ball joint) or rubber bushing at each end. Consequently, they react to loads along their own length, in tension and compression, but not in bending. Some multi-links do use a trailing arm, control arm or wishbone, which has two bushings at one end. On a front suspension one of the lateral arms is replaced by the tie-rod, which connects the rack or steering box to the wheel hub. Layout In order to simplify understanding, it is usual to consider the function of the arms in each of three orthogonal planes: *Top view: The arms have to control toe/steer and lateral compliance. This needs a pair of arms longitudina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limited-slip Differential
A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors and originally used for its Chevrolet branded vehicles. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. Early history In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance. The ZF "sliding pins and cams" became available, and one example was the Type B-70 used during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-valve
A multi-valve or multivalve Four-stroke engine, four-stroke internal combustion engine is one where each Cylinder (engine), cylinder has ''more than two'' poppet valve, valves – more than the minimum required of one of each, for the purposes of air and fuel intake, and Exhaust system, venting exhaust gases. Multi-valve engines were conceived to improve one or both of these, often called "better breathing", and with the added benefit of more valves that are smaller, thus having less mass in motion (per individual valve and spring), may also be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering even more intake an/or exhaust per unit of time, thus potentially more power (physics), power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five poppet valves per cylinder, to achieve greater performance. In automotive engineering, any four-stroke internal combustion engine needs at least two v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
