Penta Engine
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. 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 brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, with a steel foundry that soon started making hand tools and kitchen equipment, and the ... 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 relatively high ...

Nissan VQ35DE 005
, trading as Nissan Motor Corporation and often shortened to Nissan, is a Japanese multinational automobile manufacturer headquartered in Nishi-ku, Yokohama, Japan. The company sells its vehicles under the Nissan, Infiniti, and Datsun brands, with in-house performance tuning products (including cars) labelled Nismo. The company traces back to the beginnings of the 20th century, with the Nissan ''zaibatsu'', now 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 43.4% voting stake in Nissan, while Nissan holds a 15% non-voting stake in Renault. Since October 2016 Nissan has held a 34% controlling stake in Mitsubishi Motors. In 2013, Nissan was the sixth largest automaker in the world, after Toyota, General Motors, Volkswagen Group, Hyundai Motor Group, and Ford. In 2014, Nissan was the largest ca ...

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, so 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 which he ...

Cylinder (engine)
In a reciprocating 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 to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ...

Hemi Engine
A hemispherical combustion chamber is a type of combustion chamber in a reciprocating internal combustion engine with a domed cylinder head notionally in the approximate shape of a hemisphere (in reality usually a spheric section thereof). An engine featuring this type of hemispherical chamber is known as a hemi engine. History Hemispherical combustion chambers were introduced on some of the earliest automotive engines, shortly after the viability of the internal combustion engine was first demonstrated. Their name reflects the domed cylinder head and the top of the piston enclosing a space that approximates a half of a sphere ('' hemi-'' + '' -sphere'' + '' -ical''), although in practice the actual enclosed space is generally less than half. Hemispherical cylinder heads have been used since at least 1901; they were used by the Belgian car maker Pipe in 1905 and by the 1907 Fiat 130 HP Grand Prix racer. The Peugeot Grand Prix car of 1912 and the Alfa Romeo Grand Prix car of 191 ...

Peugeot
Peugeot (, , ) is a French brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, with a steel foundry that soon started making hand tools and kitchen equipment, and then bicycles. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first car steam tricycle, in collaboration with Léon Serpollet in 1889; this was followed in 1890 by an internal combustion car with a Panhard- Daimler engine. The Peugeot company and family are originally from Sochaux. Peugeot retains a large manufacturing plant and Peugeot museum there. In February 2014, the shareholders agreed to a recapitalisation plan for the PSA Group, in which Dongfeng Motors and the French government each bought a 14% stake in the company. Peugeot has received many international awards for its vehicles, including six European Car of the Year awards. Peugeot has been involved suc ...
