Frankly, if this type of engine has been ignored for the sake of money, it is SHAME:
By way of comparison, a split-cycle displacement 50 cm3 (i.e. the volume swept by all the pistons during one revolution of the output shaft) at a torque equivalent to that of a Ferrari F40 with a 8-valve, 32-liter V3 engine, 478 HP at 7000rpm which develops 59.6 m.kg at 4000rpm. This results in a smoother ride.
..... and in addition it would run on 2/3 water and 1/3 gasoline ... all hybrids would be beaten down.
There may be reliability and life (lubrication?) Problems but in theory this is exceptional.
If I understand correctly the IFMA of Clermont Ferrand (at home) is interested

Anyway, it's not tomorrow that the manufacturers will get started when we see that even the Japanese have switched to diesel (TOYOTA diesel clean power). I would like to know that hides the "clean power" in reality .....
Only when he has brought down the last tree, the last river contaminated, the last fish caught that man will realize that money is not edible (Indian MOHAWK).
