diesel is an engine style, not a fuel. You can run a diesel engine on most anything viscous and combustible, including corn oil, gas mixed with waste oil, etc.
Dont worry, most mechanical engineers do not know this (because they arent taught it)
I’ll tell you what this chemical engineer knows…when you ruin the fuel system in a modern Diesel engine, it’s going to cost several thousand dollars in parts and labor to fix. And running that shit instead of DIESEL FUEL (yes, diesel is also a fuel) will ruin your fuel system.
Nope. there are diesel fuel standards. Lots of them. and the consequences of not running say USA ULSD depends on what you mean by modern. The liquid-piston engine can switch fuels easily. Your 2022 Chevy, probably not without reprogramming the ECU. As far as old school diesel engines, we've been running them for literally millions of miles (beyond the expected life of any modern vehicle) on waste veg oil, used motor oil, and all kinds of other liquid fuels. While you may have a degree, how many diesel engines have you ran at length on alternative fuels?
None. I’ve owned 3 Powerstrokes, two farm tractors, and one VW Golf…all diesel. Yes, I’d run an old technology diesel engine in the tractors on your shit. And I might run that shit in an oil home heating unit. But not in the modern engines.
I don’t have “a” degree…I have two.
The waste oil has a high ash content and will plug particulate filters. The contaminates in waste oil will attack metals in the fuel system. Gasoline mixed with oil is a flammable (Flash point below 125F) liquid; diesel is a combustible liquid and somewhat safer
You’re right…I have no experience in running shitty diesel substitute in modern diesels… because won’t risk the bad experiences
