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 ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high- pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engi ...

Petrol
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Jaguar Cars
Jaguar (, ) is the luxury vehicle brand of Jaguar Land Rover, a British multinational car manufacturer with its headquarters in Whitley, Coventry, England. Jaguar Cars was the company that was responsible for the production of Jaguar cars until its operations were fully merged with those of Land Rover to form Jaguar Land Rover on 1 January 2013. Jaguar's business was founded as the Swallow Sidecar Company in 1922, originally making motorcycle sidecars before developing bodies for passenger cars. Under the ownership of S. S. Cars Limited, the business extended to complete cars made in association with Standard Motor Co, many bearing ''Jaguar'' as a model name. The company's name was changed from S. S. Cars to Jaguar Cars in 1945. A merger with the British Motor Corporation followed in 1966, the resulting enlarged company now being renamed as British Motor Holdings (BMH), which in 1968 merged with Leyland Motor Corporation and became British Leyland, itself to be nationa ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ...

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda City
The is a subcompact car which has been produced by the Japanese manufacturer Honda since 1981. The City was originally a 3-door hatchback/2-door convertible for the Japanese, European and Australasian markets. The 3-door City was retired in 1994 after the second-generation and replaced by the Logo. The nameplate was revived in 1996 for use on a series of subcompact four-door sedans aimed primarily at developing markets, first mainly sold in Asia but later also in Latin America and Australia. Since then, it has been a subcompact sedan built on Honda's Global Small Car platform, which is shared with the Fit/Jazz (a 5-door hatchback), the Airwave/Partner, and the first-generation Mobilio — all of which share the location of the fuel tank under the front seats rather than rear seats. The seventh-generation model launched in 2019 features a significant size growth, offering an exterior dimension on par with the ninth-generation Civic sedan. This generation also marks the introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda Accord
The , also known as the in Japan and China for certain generations, is a series of cars manufactured by Honda since 1976, best known for its four-door sedan variant, which has been one of the best-selling cars in the United States since 1989. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, station wagons, hatchbacks and a Honda Crosstour crossover. Since its initiation, Honda has offered several different car body styles and versions of the Accord, and often vehicles marketed under the Accord nameplate concurrently in different regions differ quite substantially. It debuted in 1976, as a compact hatchback, though this style only lasted through 1989, as the lineup was expanded to include a sedan, coupe, and wagon. By the sixth-generation Accord at the end of the 1990s, it evolved into an intermediate vehicle, with one basic platform but with different bodies and proportions to increase its competitiveness against its rivals in diff ...

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 ...

Harry Ricardo
Sir Harry Ralph Ricardo (26 January 1885 – 18 May 1974) was an English engineer who was one of the foremost engine designers and researchers in the early years of the development of the internal combustion engine. Among his many other works, he improved the engines that were used in the first tanks, oversaw the research into the physics of internal combustion that led to the use of octane ratings, was instrumental in development of the sleeve valve engine design, and invented the Diesel "Comet" Swirl chamber that made high-speed diesel engines economically feasible. Early life Harry Ricardo was born at 13 Bedford Square, London, in 1885, the eldest of three children, and only son of Halsey Ricardo, the architect, and his wife Catherine Jane, daughter of Sir Alexander Meadows Rendel, a civil engineer. Ricardo was descended from a brother of the famous political economist David Ricardo, a Sephardi Jew of Portuguese origin. He was one of the first people in England to see ...

George Brayton
George Bailey Brayton was an American mechanical engineer and inventor. He was noted for introducing the constant pressure engine that is the basis for the gas turbine, and which is now referred to as the Brayton cycle. Brayton's Ready Motor In 1872 George Brayton patented a constant pressure internal combustion engine, initially using vaporized gas but later using liquid fuels such as kerosene and oil, known as ''Brayton's Ready Motor'', The engine used one cylinder for compression, a receiver reservoir, and a separate power/expander cylinder in which the products of combustion expanded for the power stroke. The significant difference from other piston driven internal combustion engines is that the two cylinders are arranged so that the fuel/air mixture burns progressively at constant pressure as it is transferred from the compressor cylinder and reservoir to the working/expansion cylinder. In the original version a gas/air mixture was created by a vapor carburetor, then com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
