Hi!: as discussed, the Toyota SAE paper 790435, T Kohno et al, claimed a
7% fuel economy improvement
 in an street car under low load operation, by substituting a Glow-Plug
for the ordinary Spark Pug in the
 leading site, and adding a Reed-Valve close to the housing working
surface in a Peripheral Intake Port.
The attached patent is about one of these Glow-Plugs. Any comment?
    Thanks, best regards, + salut

It is perfectly legal to screen capture part of SAE papers.
With out the paper I cannot comment.

That attachment is in German. If you get it translated let me know.
Reed valves pay a fuel  penalty at the higher HP levels.
