What is CVVT?

        The benefits of Continuous Variable Valve Timing (CVVT) or more generally known as Variable Valve Timing (VVT), is known in the Automotive Industry including after market high performance sectors to improve engine efficiency by a respectable double digit margin. Notable potential of CVVT is exposure to camshaft degreeing. Degreeing a camshaft is widely known in racing communities to improve engine power in the RPM range most needed by “phase shifting” the zero timing reference between the crankshaft and the camshaft(s) from torque (advancing) to horsepower (retarding) or vice versa.  The down fall of a fixed position is that what is gained on one spectrum reduces the other.  This is because of mechanical limitations of poppet valve operating speeds and the singular nature of timing for the valve events.  The result is a narrow band of the highest efficiencies.  When the valve event timing can be flexible to adjust to varied RPM ranges, then the highest efficiencies are found in all RPM ranges.

Pressure to meet environmental goals and fuel efficiency standards is forcing auto manufacturers to turn to VVT as a solution. Most VVT systems (like Mazda's S-VT) advance or retard the timing of the intake or exhaust valves. Others (like Honda's VTEC) switch between two sets of cam lobes at a certain engine RPM. Still others (like BMW's Valvetronic) can alter timing and lift continuously, as in CVVT. [1]

        Current working means of CVVT exhibit median performers mainly due to complex mechanical aspect and the lack of continuous functionality, but also lean cost effectiveness is demonstrated through limited visibility of use.  Yet, despite the long history of failed and meager performance, manufacturers still acknowledge the greatest untapped potential to advance engine efficiency is through improvements to valve event timing.  
        Many much more simplistic CVVT Phase Shifting configurations of the past were abandoned due to invalid geometries.  Many only realized geometry problems upon working with prototypes and performing life cycle tests. Additionally, many more are derived from prior invalid geometries which in turn built a network of useless geometries.

        Automotive Manufacturers are very active towards implementing CVVT technology, most resorted to expensive and limited means of VVT mainly due to simple designs of decades past that failed to negotiate valid Phase Shifting geometries to properly function.  Presently, by applying an “Algorithm” to phase shifting geometry designs, the deemed “failed” simple concepts can be implemented.  AES Industries has this Intellectual Property available providing a boost path for the economy by offering manufacturers streamlining needed for simpler, smarter engines that are more efficient / green.  

        So with the Algorithm, the most cost effective simplified solution offering CVVT to both present day and past engine designs are but an update kit away.  The solution will easily find its way to helping many existing vehicle engines.  Oh yes! this applies to engines in current stock cars, muscle cars or even the daily wagon.
