Hengst launches “Blue Disc”, the smartest yet simplest solution to one of the oldest problems in engine design.  Ultra clean and kind to the environment yet ingeniously clever but most of all, effective. “Sometimes less really is more!”

The modern internal combustion engine really is a precision manufactured piece of technology with parts produced using CNC machines with mind blowing repeatability.  Some of the dividends that accrue from Computer Aided Design (CAD) and Computer Numerically Controlled (CNC) machines are precise tolerances between moving parts.

Add to this modern lubricants and the materials technology that while everyday bread and butter today simply didn’t exist a two decades ago and you have pistons moving in cylinders with less friction yet better compression seal than ever before.

One of the main benefits of all this science is reduced leakage of cylinder pressure past the pistons carrying with it nasty toxic gasses.  Some combustion gasses do however still find their way to the crank case and will either pollute the engine oil with fuel and other gas contaminants while some of this gas unless controlled will escape to the environment.  Not good!

There is absolutely nothing new about re-burning these gasses by drawing them back into the air inlet tract of the engine.  The inside of the crank case however is a busy spot with oil thrown from crankshaft big ends and often sprayed under the pistons for both cooling and lubrication.  Taking the gas out of the crank case therefore means taking oil vapour, condensed water and un-burnt fuel out inadvertently, suspended in microscopic droplets.  Traditionally some form of gauze or labyrinth arrangement has been used in the hope that the droplets would just stick together and drip back to the oil sump.  These strainers however effectively collect contaminants and their effectiveness falls off with time.

The clever people at Hengst, a company dedicated to super high-tech fluid control in modern engines have a very clever way of solving this problem.  Centrifugal acceleration of the crank case gasses within a helical disk results in super efficient separation of the gas and oil vapour, taking contaminants back to the oil sump where of course a Hengst oil filter will clean the long-life engine oil for perfect operation.  Watch the video to see how it works and then click on the link below to find Hengst filters for your car.
