Koenigsegg’s Tiny Monster And Other Innovations

The Koenigsegg
Koenigsegg is one of the hot supercar makers in the world. The Koenigsegg Ragera has a 5- liter engine which is way too small for producing 1160hp. They use innovative technologies such as distributed control units. This will make it failsafe, that means even if one control unit fails, the rest are perfectly working.
The Koenigsegg Ragera
The Koenigsegg Ragera needed some improvements as it is also street legal. It had to provide some amount of comfort during the initial acceleration for being a $2million car.

Triplex suspension system

The Triplex suspension system
Koenigsegg’s ragera uses the Triplex suspension. It has an anti-roll bar that acts during cornering. The 3rd damper is used to counteract the anti-roll bar during acceleration and driving through bumpy roads. 

The rear suspension dipping

The suspension while dipping
When you have a lot of power, a lot of new problems arise such as the rear suspension dipping while accelerating and this affects the handling. Most of the manufacturers solve this problem by changing the suspension geometry so that the car can.t dip due to geometric restrictions. This dilutes the geometry needed for cornering. The 3rd damper connected to each wheel will solve this problem.

Straight on a bumpy road

Suspension in bumpy roads
When the car is moving straight on a bumpy road, there is no roll on the car but the antiroll bar still acts in this condition. If one wheel hits a bump the antiroll bar will try to pull the other wheel to reduce roll which is not even there. In this condition the 3rd damper will directly send the force to the other wheel canceling the effect of the anti roll bar. That means more comfort even during straight and bumpy roads.

Koenigsegg free valve

Free valve simplified diagram
Koenigsegg free valve is a sister company of Koenigsegg that produces the technology. The above image shows an oversimplified version of the free valve. When the valve needs to be actuated there is an electric signal that will send air into the pneumatic actuator actuating the valve, return is spring-loaded. There is a hydraulic stopper that will restrict the actuator at a place.

Advantages of free valve

Free valve system
1.This is huge! Seriously, using this technology you will have independent control of lift, timing and duration for all of the valves 
2.If there was a traditional cam shaft, due to the cam profile the valve opens gradually and the peak point duration is very less. In a free valve the valve can go directly to fully open and fully closed which will provide better air flow mixture
3.It does not need a timing chain, cam shaft, heavy cylinder head etc. 
4.According to Koenigsegg this will have 30% less fuel conception, 30% more torque, 30% more power and 50% less emission.

Koenigsegg’s Tiny Giant

2.0-liter 600hp Koenigsegg engine
The Koenigseggs Gamera has the world’s most powerful three cylinder engine. Yes! a three cylinder engine that makes 600HP that only weighs 70kg. There are two ways for an engine to make more power, by revving high and by turbo boost. This does both it revs up to 8500 RPM and has dual 29 PSI turbo’s. An interesting fact is that it has a 93.5mm bore length and revs upto 8500 rpm. That means that the average piston speed is equal to an F-1 engine.

It has Free valve

Free valve in engine
Did you notice that it has 3 cylinders and 2 turbo’s. For Koenigsegg this was easy due to their free valve. They have independent control over exhaust and intake valve. Only one turbo receives all the exhaust gasses at lower RPM and at higher RPM the exhaust gas is split between both the turbos.  You might be thinking that Koenigsegg knows better and all other manufacturers can’t provide this technology, well they could but the system is so expensive that it can be used only in expensive cars.
