Does anyone have any comments or can compare the two published English translations of the Bosch Automotive Handbook? I see SAE puts out one from Dec 2000 and Bentley Publishers puts out one from Jun 2000. The price difference is 20% (with SAE being more expensive) and really what i'm after is...
A couple questions on fuel injection...
1) How long of a pulse width is 'normal' on an injector?
2) When (compared to valve timing) is optimum to start the injection?
3) When valve open time is less than pulse width, is this very bad?
A quick bit of math shows that at even a modest 5,000rpm on...
I was reading this webpage:

And the two blue bulleted points made me pause for a second. He says:
The DCR is always lower than the SCR
The DCR does not change at any time during the operation of the engine
Either one can be explained in the...
Ok, I've got this program called Desktop Dyno 2000. Anyway, i'm sure its not the most accurate thing in the world, but its fun to play with and its pretty cheap, so why not.
Now, I put in the stats for a stock 4.9L ford and it was pretty close (http://bigblocksix.com/stock.png). A typical...
OK, in looking up some facts about the Miller Cycle, I came up with some info on the Stirling engine. Forgive me if I sound like an idiot but i'm very tired and this stuff is just sounding entirely too cool.....
Just look at this page. Is awesome...
I've been thinking more and more about this and have some thoughts....
The camshaft on a miller closes much after BDC. Between BDC and valve closing, what kind of pressure is created on a n/a engine?
The howstuffworks.com website shows the miller cam in the mazda engine to keep the intake...
While laying awake staring at the ceiling last night I was thinking of rod ratios and offsets and whatnot, and how optimum timing would change with differing offsets and rod ratios....
As I understand it, when you offset the cylinder from the crank you change the piston TDC to be different from...
The topic says it all. This question sparked from a debate on whether or not the 300cid Ford inline six is a good engine or a useless engine, but I figured you'd all have your ideas as well.
