New Ford Product Investments1. No the Mazda Skyactiv G is basically high compression spark ignition with knock controlled by residual exhaust gas in the chamber.
2. The original dual injection on the Ford system was to provide E85 through the DI injectors as detonation control to generate 600 lb ft in turbo 3.6 v6 engine, I think the MIT mule was a GM V6 but the principle is the same. It was all about replacing diesels with high boost gasoline engines but Ford and MIT had a falling out over patents, that's why Ford went with single fuel.
Changes to 2.3 were to standardise combustion chamber design and to add internal EGR which is much easier to control than external hoses. The only reason auto companies went with long stroke engines was to get better surface to volume ratio for lowering emissions, modern engines no longer require that as lighter reciprocating parts are preferred with DOHC engines.
While an I-6 is an interesting idea for F150 and Large SUVs, it could be offered as an extension to the 2.3 production line, mainly as a means for doing away with 3.5 V6 production. The only rub with that is the UAW and Ford an agreement not to close any plants in the next four years…so there's that.Mon, 06 Nov 2023 06:31:49 +0000
