Pressure accumulation is done, in today's practice,  with very low expectations of efficiency that is about 20% of the energy input value. 

Relative-Motion cylinder method can increase such return to a very high percentage, allowing an optimum usage of available energy input, best expectations on gearing equipment maintenance requirements, and unlimited hybrid arrangements possibilities.

While the Relative motion solution can be used for a naturally aspirated engine, for lower cost and less changes applied to existing technologies, a turbo charged solution, will need a new design from the ground up, including control software and operation programs. 

Higher torque requirements, can to certain extent be provided by turbo-charge-as needed arrangement. 

Conventional engine designs, sacrifice more than fifty percent of its fuel economy at a higher vehicle speeds, only to be ready for providing a needed torque when the driving conditions changes. Such loss when using a Relative-Motion Engine, can be avoided having the availability of additional forces, ready when needed through the turbo-charge-as-needed special programing.

Turbo Charge deployment is also deployed as part of a variable compression of every stroke operation.

This Package is intended for commercial and big engines.

This Package is intended for engines used for the purpose of generating electricity, where the engine can be hybrid with a turbo-charge or with a magnetic solenoid arrangement. 

The cost per KW of electricity, is expected to be much lower than today's market cost. 

The expected decrease in transportation and commercial vehicle use of fossil fuel, if the Relative-Motion engines were to be used worldwide, may decrease from 100 million barrels/day to 30 millions, and the produced remaining of gasoline and diesel, may go to produce electricity at a higher market share, considering the new much lower cost of electricity production and much cleaner and environmentally friendly operation.
