Mazda's new engine prototype
« on: November 01, 2017, 08:30:09 AM »
Hi Guys,
I came across this article on Mazda's new engine type: the compression-ignition engine.  Since Mazda has had success with their rotary "non-traditional" (Internal Combustion and Diesel) engines, it would be cool to see a new advancement in gasoline technology come to fruition.  This new engine type takes the benefits of high compression ratios of diesel and the energy-dense state of gasoline and is able to generate "20-30 percent better fuel economy".

What other cool new tech have you guys run across lately?

This is pretty awesome. I wondered why no one had done this yet, given the fact that the precursor (direct injection) has been around for a long time and this seemed like the logical next step.  I assume some of the hurdles were not overcome until highly accurate computer-controlled injection timing was implemented. 

I'm certainly excited to see others take this approach. One of the knocks against it is the fact that gasoline in a standard fuel injection engine helps to keep the valves clean and prevent carbon deposits, which you don't get with a GDI engine since the fuel is injected directly into the cylinder, bypassing the valves all together. Now, we're talking 20 to 30 thousand miles as a recommended valve cleaning interval, assuming regular oil changes have been done, but that's just one more step that'll have to be done in maintenance.

Still, very cool tech.
