See the above...
Take it to the limit, then raise the limit!.................
First they have to have diesel quality (or better) engine components, connecting rods, pistons, crankshafts, etc.
Then the transmissions, drive shafts and rear ends must be capable of handling the much greater torque.
Yes, you can do all this, probably with off-the-shelf parts, but is the extra added cost AND WEIGHT worth the small gain in efficiency?..................
It’s easier to make a diesel engine run on gasoline that the other way around.................
Why would anyone put Premium in a vehicle that does not need it? The octane rating is related to compression not a better value.
Direct injection of gasoline in engines with spark ignition is starting to become more widespread as it is generally more efficient especially at low load conditions. DI creates a stratified charge situation depending on the method of DI by injecting the gasoline at a particular spot on the top of the piston which makes the fuel and air swirl just prior to detonation. With DI gasoline can be injected into a cylinder more than once during the stroke again adding power after the detonation has started.
Di (Direct Injection) is complicated and requires a computer to manage correctly taking many inputs such as oxygen content, pressure, temperature, RPM’s and power required, the gas pedal.
Since Gasoline engines generally provide about 25% of the power produced when gasoline is burned that means that 3/4’s of it is wasted in the radiator. DI can improve that to over 30%.
Eventually when we get rid of the valve train with opposed piston designs we will get near 40%. When we learn to make high temperature ceramic parts we will be able to get over 50%. Think of that, if a car today gets 35MPG it would get 70. Talk about being energy independent. . .
Gasoline technology has a long way to go and will be around for a long time.
My friends father had a van from the 60’s that he would fill the auxiliary tank with diesel and switch over once he was cruising on the highway. IIRC it was a Chevy 6 cylinder (gas).
Of course, he also had a pyramid for sharpening his razor blades...
Doesn't everybody?....................
If I weren’t worried about inadvertently bleeding out some fine morning, I’d just switch to an old-fashioned straight razor and sharpen it with a strop. Disposable double edge razors have gotten too expensive, it irks me to pay eight bucks for a bag of them at the grocery, they can’t cost even ten cents apiece to manufacture. Seems like they dull more quickly now than in past years, too.

And all of that extra force on the bearings, piston heads, rings, etc. will cause additional wear and so the mechanical pieces have to be more robust.
On the other hand, there is more “bang for the buck.”
I can’t get one decent shave out of the cheap ones, I’ve tried.
I buy the BIC disposables and they work pretty good and are cheap.
Cheapest ones I can get more than one shave out of are Gillette Good News, the blue ones. They’re not cheap anymore, lucky to get two decent shaves. It’s very annoying.
It was actually a two part problem. The first being the lightweight construction of the GM small block engine and the second being the normal driving habit of the public.
My dad was an engineer for Cummins and taught us that you can’t drive or run a diesel powered vehicle the same as you would with a gas engine. Basically if you lug a diesel engine it will die an expensive death. Next is that diesels require more frequent oil changes.
He bought a GM 1/2 ton pickup with the OLDS Diesel and then went out and hooked up his 36 foot Holiday Rambler travel trailer to it and put 200,000 on it with no problems.
Needless to say but he was a strong advocate of the diesel technology we see on the market today but this was in the early 70’s when we had the gas crisis. He was always saying he wished someone would put a Cummins engine and an Allison 6 speed in pickup. Unfortunately he died right as Dodge came out with that package (except for the transmission).
I test drove a Ford Ranger back in the 80’s that someone had retrofitted a small diesel engine into. It was slow getting up to speed, and so damn loud in the passenger compartment the salesman and I had to yell just to talk!..................
Mazda is an impressive car company, they have some sweet models.
Car mags love them.
Would love to have a 2017 Miata sitting out in the garage getting ready for this upcoming Spring...
