The straight-nine engine (also referred to as an inline-nine engine; abbreviated I9 or L9) is a piston engine with nine cylinders arranged in a straight line along the crankshaft. The most common application is for large diesel engines used by ships.
Examples of straight-nine engines include:
In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates. The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions. This equation has a vast and important application in determining the rate of chemical reactions and for calculation of energy of activation. Arrhenius provided a physical justification and interpretation for the formula. Currently, it is best seen as an empirical relationship. It can be used to model the temperature variation of diffusion coefficients, population of crystal vacancies, creep rates, and many other thermally induced processes and reactions. The Eyring equation, developed in 1935, also expresses the relationship between rate and energy.
The inline-six engine is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders.
An isothermal process is a type of thermodynamic process in which the temperature T of a system remains constant: ΔT = 0. This typically occurs when a system is in contact with an outside thermal reservoir, and a change in the system occurs slowly enough to allow the system to be continuously adjusted to the temperature of the reservoir through heat exchange (see quasi-equilibrium). In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).
Formula Three, also called Formula 3, abbreviated as F3, is a third-tier class of open-wheel formula racing. The various championships held in Europe, Australia, South America and Asia form an important step for many prospective Formula One drivers.
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The virial expansion is a model of thermodynamic equations of state. It expresses the pressure P of a gas in local equilibrium as a power series of the density. This equation may be represented in terms of the compressibility factor, Z, as
Real gases are nonideal gases whose molecules occupy space and have interactions; consequently, they do not adhere to the ideal gas law. To understand the behaviour of real gases, the following must be taken into account:
The Nissan J series are straight-4 and straight-6 gasoline internal combustion engines produced by Nissan from the 1960s through the 1980s. It is similar to the BMC B-Series engine that was built in Japan under licence as the Nissan 1H before being de-stroked to become the 1.0 L Nissan C and 1.2 L Nissan E engines, but wasn't a direct copy.
The FJ engine was a series of straight-4 four-valve DOHC 2.0- or 2.4–litre internal combustion engines produced by Nissan in the 1980s. They were one of the first mass-produced Japanese engines with more than two valves per cylinder, as well as having electronic fuel injection.
LIAZ is a former Czech and Czechoslovak manufacturer of trucks. The company was formed in 1951 by the government as a division of Škoda, incorporating eight other truck manufacturers into a single conglomerate. In 1953 LIAZ became independent of Škoda but still continued to use its name until 1984. After the 1989 revolution, there was a significant decrease in production.
The Gnome-Rhône 9K Mistral was a nine-cylinder 550 hp (405 kW) to 700 hp air-cooled radial engine, that started life as an enlarged Gnome-Rhône 7K with two extra cylinders.
The Mulsanne Straight is the name used in English for a formerly 6 km (3.7 mi) long straight of the Circuit de la Sarthe around which the 24 Hours of Le Mans auto race takes place. Since 1990, the straight is interrupted by two chicanes, with the last section leading to a sharp corner near the village of Mulsanne. Before the chicanes were added, the Mulsanne Straight was the longest straight section of any race track in the world.
BMW Motorrad is the motorcycle brand and division of German automotive manufacturer, BMW. It has produced motorcycles since 1923, and achieved record sales for the fifth year in succession in 2015. With a total of 136,963 vehicles sold in 2015, BMW registered a growth of 10.9% in sales in comparison with 2014. In May 2011, the 2,000,000th motorcycle produced by BMW Motorrad was an R1200GS.
Colin McRae: Dirt 2 is a racing video game developed and published by Codemasters in 2009, first for the Nintendo DS, PlayStation 3, PlayStation Portable, Wii and Xbox 360, and then later for PC platforms. It is the sequel to Colin McRae: Dirt. Dirt 2 is the first game in the series since McRae's death in 2007 and the last to feature his name in the title. It is also the first and only game in the series to be available on a Nintendo home console and the last game in the series to be released on handhelds.
The Delta 1000 series was an American expendable launch system which was used to conduct eight orbital launches between 1972 and 1975. It was a member of the Delta family of rockets. Several variants existed, differentiated by a four digit numerical code. Delta 1000 was developed by McDonnell Douglas company in 1972.
A straight-seven engine or inline-seven engine is a straight engine with seven cylinders. It is more common in marine applications because these engines are usually based on a modular design, with individual heads per cylinder.
A V14 engine is a V engine with 14 cylinders mounted on the crankcase in two banks of seven cylinders. It is a very rare layout, used almost exclusively on large medium-speed diesel engines used for power generation and marine propulsion.
Daimler Straight-Eight engines were eight-cylinder in-line petrol engines made by the Daimler Company to power the largest and most expensive cars in their range. The Straight-Eight engines replaced Daimler's earlier Double-Six V12 engines. Unlike the Double-Six engines, which used sleeve valves based on the Knight patents, the Straight-Eights used conventional poppet valves in the overhead valve configuration.
The Chrysler Six was a series of cars that were all installed with the Chrysler Straight Six when the company assumed operations of the Maxwell Automobile Company in 1924, and Chalmers Automobile Company in 1926. The Chrysler Six initially consisted of several Models, then Series designations that originally declared the approximate top speed each vehicle was able to consistently maintain, then each series number was incrementally updated every new model year, and each series was offered in several body style choices. The engines were technically advanced for their time and were entered in the 24 Hours of Le Mans for 1925, 1928 and 1929.
