Chrysler Hemi engine – Modern Hemi

The current-production “HEMI” engine heads are flatter and more complex than the 1950s–’70s Hemi V8 chamber. It uses a coil-on-plug distributorless ignition system and two spark plugs per cylinder to shorten flame travel leading to more consistent combustion which helps reduce emissions. There is one coil for every cylinder, and early versions had a wasted [...]

Wankel engine – Applications

Automobile racing In the racing world, Mazda has had substantial success with two-rotor, three-rotor, and four-rotor cars. Private racers have also had considerable success with stock and modified Mazda Wankel-engine cars. The Sigma MC74 powered by a Mazda 12A engine was the first engine and only team from outside Western Europe or the United States [...]

Plymouth Valiant – Derivative models

Barracuda Automotive trends in the early middle 1960s had all the U.S. automakers looking at making compact sporty cars.

Peugeot 205 – High performance variants

205 GTI The GTI version came in 1.6-litre and 1.9-litre, in-line four cylinder configurations, and is considered one of the very best hot hatches of all time, if not the best. Compared to modern cars they can be tricky to handle, due to their tendency towards rather sudden lift-off oversteer during hard cornering, and a [...]

Roots type supercharger – Applications

Of the three basic supercharger types, the Roots has historically been considered the least fuel efficient. However, recent engineering developments by Eaton Corporation have resulted in an improved Roots-type supercharger, known as the TVS, which is more efficient than their previous models. Unlike the basic illustration, most modern Roots-type superchargers incorporate three-lobe or four-lobe rotors. [...]

Sustainability measurement – Hubbert peaks

Although Hubbert peak theory receives most attention in relation to peak oil production, it has also been applied to other natural resources. Natural gas Doug Reynolds predicted in 2005 that the North American peak would occur in 2007. Bentley (p.& 189) predicted a world “decline in conventional gas production from about 2020″. Coal Peak coal [...]
