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 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. Called the Tiny Friendly Giant (TFG) , the three-cylinder engine was specified to [ a ] displace 1988.25 cc, have two turbos and drive the front wheels while also charging ...
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 initially based its engine on a V8 engine block from Ford Racing. These engines powered the initial run of the CC monikered cars. The block for the 4.8 L (4,800 cc) V8 in the CCX (Competition Coupe Ten, to celebrate ten years of the company) was cast for Koenigsegg by Grainger & Worrall of the UK who also cast the block for the Agera ...
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).
