Multi-valve
A multi-valve or multivalve Four-stroke engine, four-stroke internal combustion engine is one where each Cylinder (engine), cylinder has ''more than two'' poppet valve, valves – more than the minimum required of one of each, for the purposes of air and fuel intake, and Exhaust system, venting exhaust gases. Multi-valve engines were conceived to improve one or both of these, often called "better breathing", and with the added benefit of more valves that are smaller, thus having less mass in motion (per individual valve and spring), may also be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering even more intake an/or exhaust per unit of time, thus potentially more power (physics), power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five poppet valves per cylinder, to achieve greater performance. In automotive engineering, any four-stroke internal combustion engine needs at least two v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toyota A Engine
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed. The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, the successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes one of the first Japanese mass-production DOHC, four-valve-per-cylinder engines, the 4A-GE, and a later version of the same engine was one of the first production five-valve-per-cylinder engines. Toyota joint venture partner Tianjin FAW Xiali produces the 1.3 L 8A and resumed production of the 5A in 2007. 1A The 1.5 L 1A was produced between 1978 and ...

Yamaha Genesis Engine
"Genesis" is Yamaha's marketing name for a range of innovative, high-performance multi-valve four-stroke motorcycle engines. The flexible design of the engine allowed Yamaha to use it on a variety of configurations, from sport bikes to outboard engines. The five-valve engine The DOHC Genesis engine has five valves per cylinder and downdraft carburetors. Yamaha adopted the 5-valve concept, using three intake valves and two exhaust valves per cylinder, because it allowed both excellent volumetric efficiency and high RPM. As designers began to appreciate the benefits of multi-valve layout, 4-valves-per-cylinder (and even 3-valves) became common. In a multivalve engine, maximum RPM is limited by the size of the largest valves: in a 3-valver, the exhaust valve is larger, and in a 4-valver, the inlet valves are larger. The significance of the five-valve engine compared to other multivalve configurations engines is that, like a 3-valver, there were more intake valves than exhaust valve ...

Single Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam") engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement (engine), displacement. It is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gases. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and increase power outputs, especially with reduced engine dis ...

Turbocharging
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

Ferrari Dino Engine
The Ferrari Dino engine is a line of mechanically similar V6 and V8 engines produced by Ferrari for about 40 years from the late 1950s into the early 2000s. The idea for the engine came from Alfredo "Dino" Ferrari, who was the son of Enzo Ferrari. Dino suggested to Enzo Ferrari the development of a V6 engine for F2 at the end of 1955. Soon afterwards, Alfredo fell gravely ill, and he was diagnosed with muscular dystrophy. While hospitalized, he discussed technical details about the engine with a recently hired engineer named Vittorio Jano. Dino would never live to see the engine; he died on June 30, 1956, at the age of 24. The Dino V6 was Ferrari's first V6 engine. The Dino V8 engine was introduced later; the latter used a flat-plane crankshaft configuration. V6 The production Dino V6 began as a discussion between Vittorio Jano and Enzo and Dino Ferrari about the ideal 1.5 L engine for use in the 1957 Formula Two auto racing series. Jano, formerly of Alfa Romeo and La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

V-twin
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders are arranged in a V configuration and share a common crankshaft. The V-twin is widely associated with motorcycles, primarily installed longitudinally, though also transversely. They are also used in a variety of other land, air, and marine vehicles, as well as industrial applications. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United ...
