Advancing the timing would make the spark happen earlier, not faster. They are claiming to be able to ignite the entire mixture faster by lighting it at multiple places. Interesting, but I don't see how an optical device would survive the environment of the combustion chamber and maintain the needed surface finishing needed for the optical properties to stay in spec.Lil' Blue Rude said:I might not understand it all the way either but they're claiming that the laser will ignite the charge faster but I think you could achieve the same thing by advancing your spark. I don't know just my thoughts on it.
I understand that advance ing the spark makes it happen earlier but lets say if the laser is making the charge burn 3 times faster at say 21degree BTC and a spark plug charge burns 3 times slower but introduces the spark in a degree earlier the charge should burn the charge in the same time as the laser. (in theory, not sure how many degres diffrence it would be just threw that out there) I understand there is a diffrence between advancing the timing and speeding up the burn but to a lesser degree it is the same thing because the both of them deal with timing. I've read alot of this stuff dealing with moddifing outboards for the past two years and like I've said before I don't see this being any kind of answer to anything.acabtp said:Advancing the timing would make the spark happen earlier, not faster.

Direct Injection has been used for a number of years on outboards, it is a great design. Diesel has always been Direct Injected but that is unrelated. I like the DI engines, have had the chance to work on some, its pretty cool and VERY efficient.bcbouy said:direct injection would be a lot more efficient as well.
