Re: Compression Ratios and their effect on torque
I'm not so sure about the diesels being 17:1 cr. the way i understand it, the hotter the air in the combustion chamber, the faster the fuel reacts with the air (basic chemistry, as heat goes up, so does the rate of reaction). so when you increase the compression and/or boost going into a diesel engine, the diesel reacts more quickly so you can burn more fuel during the power stroke. the problem with diesels when they add more fuel is that they can't always burn it all even though there is enough air in the cylender because diesel burns slowly.
