[Diy_efi] sequential injection timing

[Djfreggens at aol.com]

i fail to see how using reversion to vaporize the fuel would be nearly as 
signficant as useing less fuel. to realzie 2 things. OEM engineers have 2 
major concerns Cost and Durability. placing an injector so close to the valve 
would subject it to much larger amounts of heat IE the permanent magents 
would have to struggle to maintin the field. 2 most electro magnetic fields 
begin to break down at tempatures in excess of 215 degrees ferinheit. being 
under the vavle cover would also be a detriment to the injetor as hot oil 
would quickly destrory the plastic body. 

  the alternative was to place the injector further up stream and use 
reversion to help atomize the fuel. which is almost as effective. can we 
scintifcally quantify the difference ??????? good questions as most dynos and 
as well as fuel meters have a margin for error above 2%. 

        but there is a gentlemen who not only did a injection setup like this 
he went even further,he used the valve seat as the place of entry for the 
fuel and realized the heat int eh seat for fuel vapor. his acheivement in 
combustion efficency is remarkable. he recorded using .035 lbs of fuel per 
hp. thats a 30% improvement over convetional injection and considering he was 
using a mechanical pump its even more remarable.so to say the the OEMS have 
the best strategy for fuel delviry is a Farse by far.

   its just like the 42 igntion system. it works better but its not on todays 
cars is it ????
