Three-wheeler
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Overview Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. Other trikes include that are specially constructed for off-road use. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazda 626
__NOTOC__ Year 626 ( DCXXVI) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. The denomination 626 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Byzantine Empire * Siege of Constantinople: A horde of Avars, consisting of about 80,000 men (including large contingents of Slavs, Bulgars, and other "barbarians"), attack the walls of Constantinople. A small Persian army arrives on the Bosphorus, on the Asiatic side. The Theodosian Walls are stormed with the most up-to-date siege equipment, in the form of traction trebuchets. The Avars also have mobile armoured shelters (medieval 'sows') and siege towers; the latter are covered in hides for fire protection. The defense of the capital (12,000 well-trained Byzantine troops) is in the hands of Patriarch Sergius I and Bonus (''magister militum''). * July 3 ...

The first generation of the RX-7, SA (early) and FB (late), was a two-seater 2 door hatchback coupé. It featured a 12A carbureted rotary engine as well as the option for a 13B with electronic fuel injection in later years. The second generation of RX-7, known as the FC, was offered as a 2-seater coupé with a 2+2 option available in some markets, as well as in a convertible bodystyle. This was powered by the 13B rotary engine, offered in naturally aspirated or turbocharged forms. The third generation of the RX-7, known as the FD, was offered a 2+2-seater coupé with a limited run of a 2-seater option. This featured a sequentially turbocharged 13B REW engine.

1973 Oil Crisis
The 1973 oil crisis or first oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC), led by Saudi Arabia, proclaimed an oil embargo. The embargo was targeted at nations that had supported Israel during the Yom Kippur War. The initial nations targeted were Canada, Japan, the Netherlands, the United Kingdom and the United States, though the embargo also later extended to Portugal, Rhodesia and South Africa. By the end of the embargo in March 1974, the price of oil had risen nearly 300%, from US to nearly globally; US prices were significantly higher. The embargo caused an oil crisis, or "shock", with many short- and long-term effects on global politics and the global economy. It was later called the "first oil shock", followed by the 1979 oil crisis, termed the "second oil shock".

Fuel Consumption In Automobiles
The fuel economy of an Car, automobile relates distance traveled by a vehicle and the amount of fuel consumption, fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses (wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazda Cosmo
The is an automobile which was produced by Mazda from 1967 until 1995. Throughout its history, the Cosmo served as a "halo" vehicle for Mazda, with the first Cosmo successfully launching the Mazda Wankel engine.

Mazda chose to use the name ''"cosmo"'', reflecting international cultural fascination with the Space Race, as Mazda wanted to showcase the rotary engine as forward-thinking, with a focus on future developments and technology. Series L10A/L10B (1967–1972) The first Mazda to bear the Cosmo name (called the 110S on models intended for export) was (along with the NSU Ro80) one of the first production cars to feature a 2-rotor Wankel engine. A prototype was presented at the 1964 Tokyo Motor Show, one month before the 1964 Summer Olympics, and after the introduction of the NSU Spider at the Frankfurt Motor Show; 80 pre-pro ...

Forty-seven Rōnin
The revenge of the , also known as the or Akō vendetta, is a historical event in Japan in which a band of ''rōnin'' (lordless samurai) avenged the death of their master on 31 January 1703. The incident has since become legendary. It is one of the three major ''adauchi'' vendetta incidents in Japan, alongside the Revenge of the Soga Brothers and the Igagoe vendetta. The story tells of a group of samurai who were left leaderless after their ''daimyō'' (feudal lord) Asano Naganori was compelled to perform ''seppuku'' (ritual suicide) for assaulting a powerful court official named Kira Yoshinaka. After waiting and planning for a year, the ''rōnin'' avenged their master's honor by killing Kira, knowing full well that the authorities would likely not tolerate this vendetta's completion. They were then obliged to commit ''seppuku'' for the crime of murder. This true story was popularized in Japanese culture as emblematic of the loyalty, sacrifice, persistence, and honor that pe ...
