Does diesel fuel have more energy in it or something? What's the deal?
>>29070431D4A explains it.Feed yourself
>>29070431That's basically what every modern turbo engine does anon.They focus on low end torque and weird efficient combustion cycles.
>>29070443But why don't thay take that principle to their larger displacement gas engines to truly compete with the deisels? The Current HD gas engines are underpowered comparatively. At least from the factory.
>>29070431Diesel contains more energy, also diesel engines have much higher compression ratios and much higher combustion temperatures, the higher temps produce more efficient combustion and the higher cylinder pressures do more work
>>29070431That's already a thing. The Germans have been doing it forever. My turbo work van makes peak torque at 1250rpm. >>29070449N/A gassers will always be "underpowered" compared to a turbo diesel. They could manufacture them with a "truck cam" which is basically what the commercial version is which would move the power and torque band down lower but you typically lose power and TQ when you do that. In consumer pickups it's just better to let the engine spin and make more power and let the 10 speed deal with it. Sure you could throw a tiny turbo or two on the V8 and have a wall of low end torque but then you're making a gasser complex with defeats the purpose of going the gas route over a diesel. I'm curious what the new Cummins 6.7 gasoline version will be like. It's definitely got the power and torque bands you're looking for.
>>29070431Modern direct injected turbo gas engines pretty much behave like diesels when driven in normal traffic
>>29070465>Diesel contains more energyIts not that simple.Gasoline contains more energy by weight, diesel contains more by volume.
>>29072526And? Longer hydrocarbon chains contain more energy, the 0.15cc that an injector will inject will contain more energy when its diesel being injected vs gasoline, the 15 gallon gas tank will contain more energy when filled with diesel than filled with gasoline, fuel tanks are volume limited not weight limited, your Reddit factoid is irrelevant
