The diesel engine, named after the German engineer 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 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 a fuel 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.
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines, mechanically controlled ignition systems and early electric motor speed controllers.
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.
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 engine, abbreviated (OHV) and 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.
Corliss Orville Burandt is an American engineer who invented a system of variable valve timing in automobile engines. Working through a 1965 Chevrolet Corvair, he designed a system of putting a sensor into the cylinder to optimize the fuel-air mixture during combustion. He claims that the hybrid autos, which are on the market today, use technology from his patents.
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 is a prototype 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 Regeras, most of which were sold upon unveiling.

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 vehicless as well as internal combustion engines.
The Koenigsegg TFG is an inline-3 engine. The TFG stands for "Tiny Friendly Giant." It is a Freevalve (camless piston engine), thus it does not have a camshaft. Instead it uses electro-hydraulic-pneumatic actuators that allow it to open each valve (both intake and exhaust) independently to maximise performance and minimise fuel consumption depending on driving conditions. The actuators also have the ability to switch the engine between 2- 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 the same turbo for each set of exhaust valves developed by van der lee Turbo Systems, So this is a switchable parallel system where at low exhaust mass flow the boost is created by one turbo and the second turbo being switched by at higher mass flow amounts, thus improving transient response. 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.
