The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine. This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine or a gas engine.
Koenigsegg Automotive AB is a Swedish manufacturer of high-performance, record-breaking sports cars based in Ängelholm, Skåne County, Sweden.
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines.
The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre–World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre, Bristol Hercules, Centaurus, and the promising but never mass-produced Rolls-Royce Crecy, only to be supplanted by the jet engines.
The Koenigsegg CCR is a mid-engine sports car manufactured by Koenigsegg and the successor to the company's previous offering, the CC8S.
The Koenigsegg CC8S is a mid-engine sports car produced by the Swedish automobile manufacturer Koenigsegg. It was the company's first production automobile and the first production car to use the company's trademark dihedral synchro-helix actuation doors. At its introduction, it won several awards, including the Guinness World Record for the Most Powerful Production Engine and design awards from both Red Dot in Germany and Utmärkt Svensk Form in Sweden.
VTEC is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.
Variable valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems.
An overhead valve (OHV) engine, sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead engines, where the valves were located below the combustion chamber in the engine block.
Homogeneous Charge Compression Ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer are compressed to the point of auto-ignition. As in other forms of combustion, this exothermic reaction produces heat that can be transformed into work in a heat engine.
A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means.
The Koenigsegg CCX is a mid-engine sports car manufactured by Swedish automotive manufacturer Koenigsegg Automotive AB. The project began with the aim of making a global car, designed and engineered to comply with global safety and environment regulations, particularly to enter the United States car market. To sell cars in the US, many alterations were made to the design of the CCR; the previously used Ford Modular engine was replaced by an in-house developed Koenigsegg engine designed to run on 91 octane fuel, readily available in the United States, and to meet Californian emission standards.
The Koenigsegg CC was the first car made by the Swedish automobile manufacturer Koenigsegg.
Internal combustion engines date back to between the 10th and 13th centuries, when the first rocket engines were invented in China. Following the first commercial steam engine by Thomas Savery in 1698, various efforts were made during the 18th century to develop equivalent internal combustion engines. In 1791, the English inventor John Barber patented a gas turbine. In 1794, Thomas Mead patented a gas engine. Also in 1794, Robert Street patented an internal-combustion engine, which was also the first to use liquid fuel (petroleum) and built an engine around that time. In 1798, John Stevens designed the first American internal combustion engine. In 1807, French engineers Nicéphore and Claude Niépce ran a prototype internal combustion engine, using controlled dust explosions, the Pyréolophore. This engine powered a boat on the river in France. The same year, the Swiss engineer François Isaac de Rivaz built and patented a hydrogen and oxygen-powered internal-combustion engine. Fitted to a crude four-wheeled wagon, François Isaac de Rivaz first drove it 100 metres in 1813, thus making history as the first car-like vehicle known to have been powered by an internal-combustion engine.
MultiAir or Multiair is a hydraulically-actuated variable valve timing (VVT) and variable valve lift (VVL) engine technology enabling "cylinder by cylinder, stroke by stroke" control of intake air directly via a gasoline engine's inlet valves. Developed by Fiat Powertrain Technologies, the technology addresses a primary engine inefficiency: pumping losses caused by restricting intake passage by the throttle plate that regulates air feeding the cylinders.
The Koenigsegg Regera is a limited production, plug-in hybrid grand touring sports car manufactured by Swedish automotive manufacturer Koenigsegg. It was unveiled at the March 2015 Geneva Motor Show. The name Regera is a Swedish verb, meaning "to reign" or "to rule". Koenigsegg produced 85 units of the car, most of which were sold upon unveiling.
APEX: The Story of the Hypercar is a 2016 American documentary film directed by J.F. Musial and Josh Vietze, produced by Katherina Gaccione. It covers the definition of the automobile term 'hypercar', as well as Koenigsegg CEO and president Christian von Koenigsegg's mission to defeat the world record in the Nürburgring and Spa-Francorchamps in the Koenigsegg One:1.
Vitesco Technologies Group AG, headquartered in Regensburg, is a German automotive supplier for drivetrain and powertrain technologies. Vitesco Technologies was a business area of Continental AG until it became independent in September 2021. The company develops devices for electric vehicles as well as internal combustion engines.
The dihedral synchro-helix actuation door system is a type of door with a hinge mechanism which allows the doors to rotate 90° by sweeping outwards and upwards at the hinge. It was designed and developed by Christian von Koenigsegg on behalf of high-performance sports cars manufacturer, Koenigsegg Automotive AB. It was conceived as revolutionary when it made its debut on the CC prototype (1994–2000). The first production car to be fitted with these doors was the Koenigsegg CC8S (2002–2003). The door's primary intention was to open high enough to avoid most curbs, but low enough to avoid garage ceilings. It also minimizes the space taken at the side of the car while opening the door, which makes it easier to open the doors while being parked on tight spaces with another parked car at the side. The Koenigsegg Regera was the first car to be equipped with Autoskin, a feature which allowed this mechanism to be completely motorized by making the door sweep automatically by pressing a button. These doors are found on all Koenigsegg cars which includes:
The Koenigsegg TFG is an inline-3 engine. The TFG stands for "Tiny Friendly Giant." It is a Freevalve, thus it does not have a camshaft. Instead it uses pneumatic actuators that allows it to open each valve independently to maximise performance and minimise fuel consumption depending on driving conditions. The pneumatic actuators also have the ability to switch the engine between 2-stroke cycles and 4-stroke cycles by controlling the number of power strokes in relation to the number of idle strokes. The patent for this system was bought by Koenigsegg's sister company Cargine Engineering in 2002. The variable displacement system allows fuel economy to be 15%-20% higher than a variable camshaft engine. Cold start emissions are also drastically reduced by 60% over a variable camshaft engine. The engine is equipped with a small turbo for one set of exhaust valves, and a larger turbo for the other set of exhaust valves. However this twin-turbo is neither a sequential nor a staged system. Without the turbos Koenigsegg claims the engine is only capable of 300 hp (220 kW). The engine can operate on the Otto cycle, Miller cycle or the Atkinson cycle. Further advantages of the camless engine is that a throttle body is no longer required because of the precision of the valve timing. According to Koenigsegg CEO, Christian von Koenigsegg, when running on Gen 2.0 ethanol, the TFG becomes "at least as CO2-neutral as an EV running on renewable electric sources such as solar or wind." The TFG follows previous Koenigsegg engines in its ability to run on all major fuels, from E100 to standard gas.
