Pent-roof Combustion Chamber
In engine design, the penta engine (or penta head) is an arrangement of the upper portion of the cylinder and valves that is common in engines using four valves per cylinder. Design Among the advantages is a faster burn time of the air-fuel mix. It is similar in concept to the hemi engine, both in design and purpose, but a hemispherical cylinder head is limited to only two valves without the use of a more complex sub-rocker assembly. The four-valve penta engine design was invented by Peugeot Peugeot (, , ) is a French automobile brand owned by Stellantis. The family business that preceded the current Peugeot companies was established in 1810, making it the oldest car company in the world. On 20 November 1858, Émile Peugeot applie ... of France, to be first used in the 1911 Indianapolis 500 race. The penta engine (also termed pentroof combustion chamber) is the most common design used today by many manufacturers for four-valve-per-cylinder engines producing relativel ...

Nissan VQ35DE 005
is a Japanese multinational automobile manufacturer headquartered in Yokohama, Kanagawa, Japan. The company sells its vehicles under the ''Nissan'' and '' Infiniti'' brands, and formerly the ''Datsun'' brand, with in-house performance tuning products (including cars) under the Nismo and Autech brands. The company traces back to the beginnings of the 20th century, with the Nissan ''zaibatsu'' or called Nissan Group. Since 1999, Nissan has been part of the Renault–Nissan–Mitsubishi Alliance (Mitsubishi joining in 2016), a partnership between Nissan and Mitsubishi Motors of Japan, with Renault of France. , Renault holds a 15% voting stake in Nissan, while Nissan holds the same stake in Renault. Since October 2016, Nissan held a 34% controlling stake in Mitsubishi Motors. In November 2024, Nissan reduced its stake in Mitsubishi Motors from 34% to 24%. Nissan planned to merge with Honda Motor Company in 2026, after an announcement in December 2024. However by February 2025, ...

Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in wh ...

Cylinder (engine)
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemi Engine
A hemispherical combustion chamber is a combustion chamber in the cylinder head of an internal combustion engine with a domed " hemispheric" shape. An engine featuring this type of hemispherical chamber is known as a hemi engine. In practice, shapes less than a full hemisphere are typically employed, as are variations (or faceting in parts) of a true hemispheric profile. The primary advantage of such shapes are increased compression (leading to greater power) and very large intake and exhaust valves (allowing better flow of intake and exhaust gasses, also resulting in improved volumetric efficiency and greater power); the primary disadvantages are complex valve trains (caused by valves being placed opposite one-another in a head) and expense (of machining the heads and pistons, and additional valve train components). While hemispherical combustion chambers are still found in the 2000s multi-valve arrangements (of four and even five valves per cylinder) and the popularity of ov ...

Peugeot
Peugeot (, , ) is a French automobile brand owned by Stellantis. The family business that preceded the current Peugeot companies was established in 1810, making it the oldest car company in the world. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first vehicle, a Steam car, steam-powered tricycle. In 1886, the company collaborated with Léon Serpollet, followed by the development of an internal combustion car in 1890, which used a Panhard-Daimler-Motoren-Gesellschaft, Daimler engine. The Peugeot family and company are originally from Sochaux, where Peugeot still operates a large manufacturing facility and the Musée de l'Aventure Peugeot, Peugeot Museum. Peugeot vehicles have received numerous international accolades, including six European Car of the Year awards. The brand also boasts over a century of success in motorsport, with victories including the Indianapolis 500 in 1913, 1916, and 1919. Peugeot Spo ...
