An internal combustion engine needs a few things to work. One of those parts that makes an engine do its thing is a piece called the camshaft. This helps control the timing of the intake and exhaust valves that sit at the top of the engine. Koenigsegg is setting out to revamp anything it can related to how a car works and performs, and one way it's doing this is by creating an engine that needs no camshafts to operate. Koenigsegg calls the technology FreeValve, and Jason from Engineering Explained is here to break it down for us.
FreeValve is technically a subsidiary of Koenigsegg. It's working on a camless engine that operates by making use of an actuator based system to control the valves. This allows engineers to create independent timing profiles for all of the valves in the engine. With this level of control, you can improve efficiency, power, and fuel economy of the engine while also reducing emissions.
There's also no need for a throttle body and the packaging of the engine is more simplified compared to an engine using a camshaft system. Overall, it seems like a brilliant way to move the internal combustion engine into the future. Still, we're not quite ready to plop these into every car on the street.
It's currently prohibitively expensive since it's not a mass-market engine just yet. There is a company trying to make it happen, though. At the 2016 Beijing auto show, Chinese automaker Qoros unveiled a concept car that was equipped with a FreeValve engine. Unfortunately, it's just that at the moment; a concept. Still, if FreeValve can refine and prove this engine technology it could find greater interest with a larger automaker.
From there, it's a matter of time and money to try and make it work in a regular street car.
