Is their a noticable difference gas vs diesel

[Egon]

Welcome back Nomad.

It's obvious you have not kept up to date on the cost of fuels. Check it out.

Isn't your last statement in direct contradiction with the first one???

 

[nomad]

Egon,

I don't see any contradiction in my statements. What is it about?

What? cost of fuels have changed? Now, price of diesel is higher than gasoline?

Yes. Diesel is higher (about $ .30 cents a gallon....)

 

[nomad]

Yes. Diesel is higher (about $ .30 cents a gallon....)

In this part of the world, diesel is cheaper than gasoline (benzene.)

Why is diesel price higher there? Its refining stage is less than that of gasoline.

I just bought both fuels this weekend... unleaded was $2.79 and diesel $3.39.

So the story goes, supply and demand. Much of the production capabilities of diesel goes towards home heating oil during winter months and the available supply of diesel is limited, again, so the story goes. That rationalization is hard to accept considering there's no SHORTAGE of diesel fuel once the price reaches current levels, along with the fact there's no shortage of home heating oil either. The supply is adaquate for both uses. It's not "supply and demand", it's just "demand".

Hi Nomad, been a while.

Diesel fuel (also same as heating fuel) has gone up in price faster than gasoline here in the USA the past 16 months. I think we don't have as many refiners making it, or just marketing as others suggest. Another reason is we have gone to ultra low sulfur, and will require the fuel to work in cataltic converters by 2008 I think, so many additives or 'extras' in the fuel need to be removed. It has made the refining process cost much more than 'just make diesel fuel' and has shut down a few of the smaller outfits. Typical govt.

You gave a very good discription of the difference in gasoline & diesel engines. You described the 'power' one gets from the engines.

There is also 'torque' one gets from them.

A gasoline engine pulls hard. You get to a tough spot, where it has to pull a little harder. A gasoline engine has very little 'extra' or 'lugging' ability to pull itself through this.

A typical diesel engine has a much better 'torque reserve' available. It will pull through the tough spot, giving up rpm speed for more power for a limited time.

So, the diesel engine, tho it has the same hp as the gasoline engine, will pull through a tougher spot in a field if you are plowing. Typically. You cannot use that 'lugging ability' as full-time power tho.

Hp is the full-time power of the engine.

Torq is the temperary extra power (at the sacrifice of rpm) you can get from an engine.

Diesel gives you better torq for the same hp.

I may have blurred some terms here, just trying to make the basic point. I might fail a technical test on the issue tho. It's difficult to explain simpley but accurately.

Hi Paul, yes, as always, you have blurred some terms again.

You say "Hp is the full-time power of the engine." - NO, HP, i.e. POWER is an "instant" term, i.e. work or energy per unit time.

Again, you say "Torq is the temperary extra power." - NO, Torque is in the same class of work or energy, that's, torque is a term dependent on a road, a period, so on.

Most of misunderstandings in such technical communications especially among rural people come from the language they use. Let me describe things, relationships between hp, torque, work, and so on in a language (semi or mixed technical language) we both can understand each others.

POWER (HP, Watt, etc) = WORK (OR ENERGY) per TIME.
Linear Motion: POWER (HP, W,) = FORCE x SPEED (mph, kmph,..)
Angular motion: POWER (HP, W,) = TORQUE x SPEED (RPM, radian, etc.)

Our PTO does angular motion. So, P = T x RPM. (omitting some constants)

So, if our P (HP) "at" PTO is SAME, and also IF RPM "at" PTO too is SAME, then, T(orque) too is SAME following this relation P = T x RPM = constant.
In gas PTOs, RPM is higher? If it is higher, then, you are claiming that gearbox at same gear (say, at 1) has bigger gear ratio. But, this is another story. I assumed gearboxes of diesel and gasoline were same. We are asked at SAME pto HP. IF pto rpms are different, the original question should be replaced by "diesel and gasoline tractor gearboxes are different?" Then, my answer would have been different.

Around here, regular gas is $2.99. Heating oil is $3.10. Diesel is $3.50. There ain't no justice. I use more oil than the other two, this time of year, heating the outdoors around my 1840 house.

A wider spread here. Regular gas is $2.68 now. Diesel is $3.39 and home heating oil, $3.49.

For the first time in my life, it's cheaper to heat with electric. Unfortunately, I heat with gas. We pay gas and electric bill to one company. Their electric rates are fair. Their gas rates are outrageous.

It's also cheaper to drive my gas (Hemi) Dodge 2500 over the Cummins diesel Dodge 2500.
