The benefits of such an engine are obvious. The biggest such benefit, not mentioned yet, is the fuel savings and expected life. This device is claimed to reduce fuel consumption by up to 8% due to the reduction of component weight and friction.  The technology is being called a one-cycle” engine in that the engine can not draw in air because the piston is firing in both directions.  It therefore needs a supercharger to get started and at turbo charger to run efficiently.  The fact that it is a one cycle allows high torque and its balanced design requires a much smaller flywheel.  Again, it should be mentioned that without valves we do not see this engine being used to replace today’s car engine.  The engine is designed and is most efficient when it is run at given RPM over long periods of time.
