New Mazda petrol engines to have no spark plugs

So it seems that Mazda have taken compression ignition technology from Diesel engines and applied it to petrol engines. I can only imagine that this will have an incredibly high compression ratio and become horribly unreliable at higher mileages.

Well at least you can give Mazda props for trying to improve the technology, only people in the world to have a successful wankel engine vehicle and a pretty good one at that.

Maybe there will be a solution which they will come up with!?

@Barry can you kindly explain in brief how the compression engine technology saves more fuel as compared to the spark from the plugs technology. Also please advise why high compression ratio becomes unreliable at higher mileage and how this is taken care of in a diesel engine. Thank you in advance.

Honestly, this is new to me and not something I know much about although I believe the decreased reliability would come from the much higher strain on internal engine components.

So @Barry this is your assumption, well in a few years time when the problems arise you can always tell us..."I told you so"
