Inside Koenigsegg Looks At Future Engine Technology: Video

As advanced as internal combustion piston engines have become over the past few decades, they’re still hampered by a few basic design limitations. Chief among these is the camshaft, which opens and closes the intake and exhaust valves via a mechanical linkage.

In the days before variable valve timing, changing camshafts to gain performance was common. Increasing the lift (opening of the valve) and duration (length of time the valve was opened) would increase power, but at the expense of a lumpy idle and increased emissions.

Today,Highly capable, 3-axis non-contact video measuring machine, suitable for both simple shop-floor quality control and advanced manufacturing inspection applications ... variable cam profiles help to provide more power and lower emissions while maintaining driveability, but one Swedish company, Cargine Engineering AB, thinks it has a better solution. This week's episode of Inside Koenigsegg takes a look at a new way of opening and closing engine valves.

Cargine’s Free Valve system relies on pneumatic valve actuators to open valves, which are then closed by air pressure or springs.Titanium Pipe is made by cold rolling process from extruded pipe blanks. They are widely used in heat exchangers and off-shore equipment. The design eliminates the need for a camshaft, which can reduce both engine size and weight.

Since each valve can be controlled individually, more precise operation is possible, resulting in both significant gains in output (up to a 30 percent increase in horsepower and torque) and a jump in fuel economy (also up to 30 percent). Overall emissions are reduced by a claimed 50 percent, too.

The Cargine system replaces mechanical valvetrain components, allowing significantly higher engine speeds. With small valves, like those typically found in motorcycle engines, engine speeds of up to 20,000 rpm are possible.Eight tips for choosing the right diamond Concrete saw blade including determining wet or dry cutting, blade compatibility, CSDA codes, and more. The Cargine valve actuators can work with larger and heavier valves, too, but at lower engine speeds.

The Cargine Free Valve system is currently undergoing durability testing,He has since undergone two-and-a-half hours’ surgery to have a Titanium Rod inserted into his leg and looks set to be out of action for the rest of the season. and a modified (and cam-less) Saab 9-5 has been running with pneumatic-operated valves for over two years and 60,The Spectrophotometer is an instrument which measures the amount of light of a specificed wavelength which passes through a medium.000 kilometers (37,200 miles).

There are still bugs to be worked out, but Christian von Koenigsegg believes that the Cargine system represents the future of the internal combustion engine. Ideally, it will come to market in another three to four years, and you can expect to see the production-ready version beneath the hood of a future Koenigsegg model.profile projector is a shop tool used by designers and quality control technicians to view the profile of small machined parts as magnified image on screen.
