How the motor works

[greentuck]

I have posted several times on here and so far this is a GREAT sit with GREAT people. Very helpful.

I am a newbie to say the least. New to the diesel world. I am not a great mechanic but can find my way around and most of all I am very analytical and thorough when I set out to do something -- wife says I research a topic to death.


With that said I feel that before I can go forward and be any good at working on my own truck I need to know how the dang thing works -- kinda like before you can operate you gotta know the human anatomy and where the parts are and what they look like then the physiology how they work together before you can operate hence fixing, deleting or adding on.

So if you guys would be so kind to point me in the direction of some good websites that show the anatomy of the truck, and then the physiology and how it works I think from there my questions to the forum will be more intellegent as oppose to shots in the dark-- plus I just want to learn. Or I am up to reading your post-- I have my pen and paper just need a teacher for class to start.

I have never really been the kind of guy that works on his cars but this truck has me mesmorized and i am finding out that I could get addicted to working and improving her-- very self satisfying.

I have several questions and I am going to post most of them seperately as to not bog a thread down with multiple questions -- also should make it easier for the other newbies out there to learn by searching for specific topics.

Thanks for all the help. Look forward to reading what you guys have to say.

Well, do you know how a motor in general works? If not, I'd just wikipedia or google it. I'm sure there's all kinds of good pictures and such.
If you know how a motor work, a powerstroke is roughly the same.
How HEUI works and best to convert
This is a good description of how the HEUI system works to power the fuel injectors on the Powerstroke.

GAS:

Thanks alot have not read all yet but definately will begin. I left the question very open as I did not want inhibit any response. I understands the basics of how it works but they work a good bit different than a gas motor although Zair... made it barney simple I just believe truly understanding how she works will help in diagnosis as well as repair. Hopefully some of the reading material will also lay out what I am looking at and where to find some of these parts-- Thanks again and keep up the post if you feel like it this is definately something a newbie will want to see.

I'm GLAD someone finally asked how they work. Diesels have the same motion as gas motors. Completely different workings though.
An HEUI motor moves the same as a IDI, DI non common rail, or common rail DI motor, but is actuated differently. It's nice to see someone actually wanting to learn about the basics of it instead of wanting major help right away without knowing anything.
HEUI - http://www.cat.com/cda/files/87775/7/pehp9526.pdf - They literally wrote the book on this.
Indirect Injection -

IDI diesel Theory - YouTube

Indirect injection - Wikipedia, the free encyclopedia

Direct Injection - Just has a fuel injector directly into the combustion chamber. No pre combustion chamber like the IDI. I was too lazy to search cause this one's easy.
Common Rail - Common rail - Wikipedia, the free encyclopedia

Non Common Rail - Has a high pressure fuel pump like CR, but there is no common rail for supply. Each injector has an individual supply line off the HPFP. Once a certain pressure is reached in each injector, it opens and fires so it is not electronically opened like a common rail.

Now this tread is cooking with gas or should I say desiel-- thanks I will begin reading.

I am also glad this was brought up. I have a question about diesel in general. How does it fire? When the starter cranks the motor what happens to start the engine. If I remember correctly diesel combusts under alot of heat and pressure? So the piston compresses it and the glow plug adds the heat?
I have seen a video of a powerstroke running without the glow plugs, how is that possible? As I know a gas engine cannot run without spark plugs.

[cweiss87]

Glow plugs only aid in cold starts. They aren't needed for a diesel motor to run like a gas engine needs the spark plug. Diesel fuel is ignited by high compression and the glow plugs help heat the cylinder when the engine is cold.

[jshalala]

So does the friction in the cylinder combined with the pressure cause the diesel to ignite?
