CVCC
CVCC, or , is an internal combustion engine technology developed and trademarked by the Honda Motor Company. The technology's name refers to its primary features: Compound refers to the use of two combustion chambers; Vortex refers to the vortex generated in the main combustion chamber, increasing combustion speed, and Controlled Combustion refers to combustion occurring in a timely, controlled manner. The engine innovatively used a secondary, smaller auxiliary inlet valve to feed a richer air-fuel mixture to the combustion chamber around the spark plug, while the standard inlet valve fed a leaner air-fuel mixture to the remainder of the chamber, creating a more efficient and complete combustion. History Following the establishment of an "Air Pollution Research Group" by Honda in 1965, its collection of emissions data from American automakers, and subsequent research into emissions control and prechambers, the first mention of CVCC technology was by Soichiro Honda on Fe ...

Honda E Engine
The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ''ED1'' engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter. The CVCC ''ED1'' was on the Ward's 10 Best Engines of the 20th century list. EA :''Also see the Japanese Wikipedia entry'' The EA-series is a water-cooled inline two-cylinder engine replacing the N360's air-cooled engine. An SOHC design with a timing belt (replacing the chain used in the N360 engine), the EA was first seen in the 1971 Honda Life. This engine was derived from the air-cooled engine in the Honda CB450 and was adapted for water-cooled application. The displacement was reduced to be in compliance with Japanese kei car legislation that stipulated maximum engine displacement. Bore and stroke were . A version producing at 8,000 rpm was ins ...

Stratified Charge Engine
A stratified charge engine describes a certain type of internal combustion engine, usually spark ignition (SI) engine that can be used in trucks, automobiles, portable and stationary equipment. The term "stratified charge" refers to the working fluids and fuel vapors entering the cylinder. Usually the fuel is injected into the cylinder or enters as a fuel rich vapor where a spark or other means are used to initiate ignition where the fuel rich zone interacts with the air to promote complete combustion. A stratified charge can allow for slightly higher compression ratios without " knock," and leaner air/fuel ratio than in conventional internal combustion engines. Conventionally, a four-stroke (petrol or gasoline) Otto cycle engine is fueled by drawing a mixture of air and fuel into the combustion chamber during the intake stroke. This produces a homogeneous charge: a homogeneous mixture of air and fuel, which is ignited by a spark plug at a predetermined moment near the top of the ...

Mechanical Engineering Heritage (Japan)
The is a list of sites, landmarks, machines, and documents that made significant contributions to the development of mechanical engineering in Japan. Items in the list are certified by the . Overview The ''Mechanical Engineering Heritage'' program was inaugurated in June 2007 in connection with the 110th anniversary of the founding of the JSME. The program recognizes machines, related systems, factories, specification documents, textbooks, and other items that had a significant impact on the development of mechanical engineering. When a certified item can no longer be maintained by its current owner, the JSME acts to prevent its loss by arranging a transfer to the National Science Museum of Japan or to a local government institution. The JSME plans to certify several items of high heritage value over years. Categories Items in the Mechanical Engineering Heritage (Japan) are classified into four categories: # Sites: Historical sites that contain heritage items. # Landmarks: ...

Toyota TTC
Toyota TTC stands for Toyota Total Clean System, a moniker used in Japan to identify vehicles built with emission control technology. The technology was installed so that their vehicles would be in compliance with Japanese Government emission regulations passed in 1968. The term was first introduced in Japan, with an externally mounted badge on the trunk of vehicles equipped. The technology first appeared in January 1975 on the Toyota Crown, the Toyota Corona Mark II, the Toyota Corona, the Toyota Carina, the Toyota Corolla, and the Toyota Sprinter. There were three different versions initially introduced, called TTC-C for Catalyst, installing a catalytic converter, TTC-V for Vortex, installing an exhaust gas recirculation valve, and TTC-L which used a lean burn method. As Toyota's technology evolved the three systems were eventually used in conjunction in future models. The TTC-V was a licensed copy of Honda's CVCC system, and was first introduced in February 1975. It was only a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...
