The first 6-speed manual transmission was introduced in the 1967 Alfa Romeo 33 Stradale. The first 7-speed manual transmission was introduced in the 2012 Porsche 911 (991). [9] In 2008, 75.2% of vehicles produced in Western Europe were equipped with manual transmission, versus 16.1% with automatic and 8.7% with other. [10]
Excessive hammer blow from high slipping speeds was a cause of kinked rails with new North American 4–6–4s and 4–8–4s that followed the 1934 A.A.R. recommendation to balance 40% of the reciprocating weight. [8] Out-of-balance inertia forces in the wheel can cause different vertical oscillations depending on the track stiffness.
The Pierce Four was the first four-cylinder motorcycle produced in the United States. [5] [6] [7] ... Many of their bicycles used a shaft drive for the rear wheel ...
The Lanchester design of balance shaft systems was refined with the Mitsubishi Astron 80, an inline-four car engine introduced in 1975. This engine was the first to locate one balance shaft higher than the other, to counteract the second order rolling couple (i.e. about the crankshaft axis) due to the torque exerted by the inertia caused by ...
A four-wheel drive, also called 4×4 ("four by four") or 4WD, is a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges .
Among the first overhead camshaft engines were the 1902 Maudslay SOHC engine built in the United Kingdom [18]: 210 [15]: 906 [30] and the 1903 Marr Auto Car SOHC engine built in the United States. [31] [32] The first DOHC engine was a Peugeot inline-four racing engine which powered the car that won the 1912 French Grand Prix.
The way in which a flat-plane works within a V8 engine is more like two in-line 4-cylinder engines mated together, [1] with the firing order of each order being in a Right-Left-Right-Left-Right-Left-Right-Left pattern. [6] Being in this in-line configuration allows for the engine to rev much faster, making it more suitable for racing engines.
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, [1] is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine , each pair of opposed pistons moves inwards and outwards at the same time.
