I have been waiting for this point in time. With diesel emission equipment getting so complex and unreliable, the cost of diesel,...... at what point do manufacturers say.... maybe we should start coming out with industrial gasoline engines again. I say again because most manufacturers had industrial gas engines in the past.

[@frederickjeremy]

I’ve been wondering this for years.

[@davidperry4013]

Before DPF filters, diesels are inherently more reliable than gasoline. DPF filters have greatly stymied the reliability of diesel engines. The only medium duty diesel that has a reliable DPF is the HINO J08E because it’s a Toyota. There is once a rumor of an HD tundra with that same 7.7 liter inline 6 diesel.

The brothers survived his teenage son racing people at 100 mph many times before he turned it upside down & once righted the engine still managed to start & run!

[@geoffmooregm]

Yes GM *kind of* put different heads on the Olds 350 to make a Diesel. However there were lots more changes that made it happen. The blocks were beefed up a lot. So much in fact that a scrap Olds D/DX block can be turned into a max effort gas engine with a bit of machining and stay together at almost any power level the rotating assembly can handle. The problem at the time was not that they "converted" a gas engine. It was issues with the fuel system and gasket technology. The problems they had back then are so easy to solve these days. Cummins does have CNG engines on the road already. They are "converted" engines but they are going the other way. Cylinder pressures are much much lower on a spark ignition engine vs a diesel. The castings and forgings that make up the engine can certianly handle the work load. All they have to get right is the fuel/air delivery system.

[@davidrte.664]

Diesel is on the way out for light duty and 18 wheelers. I know, I know it will be around for years to come but changes will need to start now in order to make a smooth transition when the time comes. Even Hydrogen is being tried this year.

[@andyharman3022]

It will be really cool to see Cummins' version of a gasoline engine. Since the gummint started mandating DPF, EGR, and SCR on diesel engines they have become more expensive to buy and operate. Fuel economy has decreased to the point where a heavy duty turbocharged GDI gasoline engine would be competitive. If a gasoline engine could achieve fuel economy that is within ~10% of modern diesels, the lower pump price of gasoline (87 octane) would lower operators' overall fuel cost. And the engine would be cheaper to manufacture owing to lower fuel system cost(3000 psi GDI system vs 30,000 psi CR), and no DPF, SCR, and EGR systems. Then the owner would not have the high maintenance costs associated with those systems in the field.

[@Random-bm7ho]

Diesel engine has a higher compression ratio, too high for pump gas. Therefore they change the head design, lower the compression, change aftertratment system, computer parameters, change injectors and fuel system and now you can run gasoline. It's not as simple as just pouring gas into a unchanged engine. Gasoline will destroy a diesel fuel system, high pressure pump filters , o rings etc. It's not as simple as explained in this video.

[@samueltaylor6961]

The blocks the same. Also they been doing cng I believe 90's. The fuel system I've seen for cng is a throttle body like system. I want to see them do a multi port fuel. Also they lower the compression. The problem I seen aluminum piston don't hold up in the cng. But I always to convert the cng to gas to see want it could do.

[@om617yota8]

Calling it fuel agnostic is 99% marketing. You don't order a generic engine and then run whatever fuel you want the first time. You'd order a gasoline engine, natural gas engine, diesel engine, etc. They'd all be based on the same 6.7l platform, but very much built for the specific fuel you ordered. If you order a diesel engine and put gasoline in it the first time, it'll cause just as much damage as doing that to any other diesel engine. You might be able to get something that's gasoline/propane dual fuel, but it'd be a similar conversion or multi-fuel setup as existing dual fuel engines that can do that.

The regulations in reality are more harsh the the environment, cuz of having to make more parts to meet emissions requirements. Plus the fact that there’s no EPA regulations on cargo ships that run on crude oil, & the military that does not abide by the EPA at all. Planes done have any of it, & neither do trains! Trains don’t have a DPF yet each Locomotive burns 4000 gallons of fuel per week! So each train you pass at a railroad track with 3 Locomotives is burning close to 12,000 gallons of diesel per week!

Yes there's regulations on ships, there's actually articles out in the last two years about how the lack of titanium dioxide pollution from the ships is leading to an increase in warming. Emissions are complicated and just because your vehicle is getting better mileage doesn't mean it's producing less emissions. And it's primarily the types of emissions that are more damaging without an emission system. It's hard to understanding things you can't see
