The CVT is a very good match for automobiles. The Flydrid people have a very interesting system that incorporates the torotrack system. With even a simple CVT, the engine flywheel can be enlarged to store more energy. The flywheel can be even divided into two parts so that one is directly connected with crank shaft to keep the engine running but the other can be run over speed for regeneration; it could even restart the engine when comming out of a stop. It is likely that manual transmissions are responsible for much of the delays in the motorway traffic jams because of their inability to move very slowly in gear.

Some automobile company ought to rebuild a car with a Constantinesco transmission in it. It would be very good even for electric motor cars. In fact it could make small electric cars easier and cheaper to make. It will certainly make internal combustion engine cars with smaller engines possible.

Engines with a single large piston are more efficient than engines with the same displacement with multiple pistons. Whilst it may not be macho to have a car with a single piston, it certainly can conserve fuel in hybrid and some continuously variable transmission cars.

An electronically activated weight could balance the single piston at higher efficiency than another piston. Actually the INNAS NOAX free piston engine may be an ideal choice for single piston cars. A very low friction balance piston could be driven hydraulically, and it could even use the flexures that one free piston stirling engine company invented.

Constaninesco made hydraulic pulse generators and motors, but it is not clear if they would be better suited to the NOAX engine than the Artemis motor.

Constantinesco hydraulic pulse tranmission systems might be a very good way to activate valves or injectors for low friction and the ability to selectively disable cylinders at low power. ..HG..
