I Need The Community's Help

I have to turn in a compare/contrast essay for English class. I decided to do my topic on Similarities and differences of the Diesel and Gasoline engines. This is what I have come up with so far SIMILARATIES-Both are DI engines-Both use the 4 stroke cycle principle-Both fuels hold lubricating properties to prevent internal parts wear DIFFERENCE-Ignition-Compression-Emissions-Refining process of fuel These are just points and need to write out my supporting sentences. I feel like I am leaving a few things out that I havent thought of yet. Can anyone give me more ideas?

Energy Content DifferencesMPG DifferencesFuel cold weather differencesEngine block differences (diesel is heavier/stronger)Engine RPM Differences (Gasser revs a lot higher)Both have similar cooling systemsBoth have similar lubrication systemsBoth can use the same trans (if power is the same, V10/Cummins used NV4500HD)Both have similar electrical systems (cept for addition of grid heater)Both rely on compression to be efficientHmmmmm

I have to turn in a compare/contrast essay for English class. I decided to do my topic on Similarities and differences of the Diesel and Gasoline engines. This is what I have come up with so far

SIMILARATIES

-Both are DI engines (Becareful here Diesel is is direct injected in the cylinder and gas is injected in the manifold.)

-Both use the 4 stroke cycle principle

-Both fuels hold lubricating properties to prevent internal parts wear

DIFFERENCE

-Ignition

-Compression

-Emissions

-Refining process of fuel

These are just points and need to write out my supporting sentences. I feel like I am leaving a few things out that I havent thought of yet.

Can anyone give me more ideas?

Let me think some more...

Thanks ISX, those were good points.

Diesel is nearly twice as efficient as a gas engine. It burns I higher BTU content fuel than a gas engine and typically runs about double the compression ratio in many cases. http://www.howstuffworks.com/diesel1.htm http://auto.howstuffworks.com/question399.htm http://en.wikipedia.org/wiki/Diesel_engine Some diesels although not many modern consumer use or light duty are 2 stroke diesels. For instance some the now discontinued Detroit diesel or the Waukeshau diesels (kind of an odd duck) Hopefully this will give you some food for thought. :smart:

Just thought of another big thing that you can stem off of. Gassers hardly ever come with an engine oil cooler OEM. I think anyways, don't mess with them too much. But you could explain why it is that they don't have them and why diesels have them.

Is the class over? Hp/torque comparison per cubic inch.Potential energy in a gal of diesel vs gas.Dont forget we can make fuel in our garage for 50 some cents a gal.(used veg oil)
