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.
Camless valve trains have long been investigated by several companies, including Renault, BMW, Fiat, Valeo, General Motors, Ricardo, Lotus Engineering who developed electro-hydraulic valve actuation in the late 1980s as a spinoff of their active suspension program (both utilised similar electro-hydraulic actuation and control), Ford, Jiangsu Gongda Power Technologies, and Koenigsegg's sister ...
The Gemera is the first four-seater car built by Koenigsegg. It was announced that it would be powered by a compact engine weighing only 70 kg (150 lb). The engine was so small because it was supposed to be a camless piston engine using Koenigsegg's Freevalve technology, the first such engine announced for a production car.
The solution, he said, was melding the automaker's camless "freevalve" combustion engine tech with electric assistance. You could cold-start the vehicle using pure alcohol, for instance.
Koenigsegg has also developed a camless piston engine which found its first application in the Gemera, which was introduced in 2020. [7] Koenigsegg develops and produces most of the main systems, subsystems and components needed for its cars in-house instead of relying on subcontractors. [8]
Said claim was put to test on February 28, 2005, at Italy's Nardò Ring where a team of five Koenigsegg engineers and mechanics together with founder Christian von Koenigsegg ran a standard CCR, driven by Loris Bicocchi to a top speed of 387.87 km/h (241.01 mph), breaking the fastest production car record (if "production car" is defined ...
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
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 .
