JTS Question

I know its not exactly new, but I was reading some tech bits about the JTS engine. Understand that it uses its Jet Thrust Stoichiometric system to "spray" fuel at low revs, up to 1500rpm, before acting like a conventional fuel injection engine after. This apparently has the added advantage of better fuel efficiency and cleaner emissions.

However, this got me thinking - how does it then help achieve a 10% power increase - comparing the 2.0 Twin Spark engines 150hp to the 2.0JTS 165hp?

Also, seeing that the JTS are now the default engines:

Does it also employ twin sparks?

Does it drink as much oil as the TS?

Does it inevitably suffer the variator dead syndrome?

Is it also prone to cambelt failure?

Re: JTS Question

It only has a single spark plug per cylinder.
re oil: Probably (mechanically it is the same)
re variator: see above!
re cambelt: see above!

It develops more power because it has a higher compression ratio.
