Hi
 Thanks for quick reply. I am looking at using a single injector only
 as a performance booster on an old diesel motor injecting small
 quantities of petrol. Was going to use TPS to vary injector output,
  4 x pulse outputs off the crank.Thought that the 555 was a good
 place to start playing.

  That should work.
 Most diesel run WOT all the time and the amount power and fuel flow
 is controlled by the TPS. You'll get smoke like at a tractor pull :)
 Make sure you use the CMOS version of the 555.

  Scott,
 re you planning to use gasoline or diesel fuel? Gasoline has a major
 problem with the high compression and WILL cause knock. I would use
 propane or CNG nstead if that is the case. Dale Davies

 Have been using 20 % petrol(high octane Approx 105) using wvo(waste
 veg oil) just seems to advance ignition on the diesel motor. Thought
 that electronic injection (as sorts) would be a bit me precise in
 volume and injected timing This a booster ,not on 100% of the time.
 Mate,just playing around to keep the busy and learning at the same
 time. love to play with all sorts of different stuff.Any input is
 taken on-board and not to have the nose turned up at it, if you know
 what I mean. Thanks In Advance scott

 You've got me confused Scott! I too use gasoline with WVO to improve
 starting in the Oz winter, but I use the lowest octane I can find to
 improve the Cetane rating of the fuel  - in case  you don't know
  Cetane rating is the inverse of Octane rating.

 As it is timed injection in a diesel it is best carefully mixed with
 the WVO before putting in the tank. Yesterday it would not start on
 15%  on an 8* C morning so I am going back to  20%. Mercedes
 recommend not exceding 30%.

 No worries Scott,
I did not know what you were doing. Got it now.

Was away to Red Deer, Alberta for Rock'n'Red Deer, a car show and shine on the
August long weekend here. It rotates between Red Deer, Brandon, Manitoba and
Saskatoon, Saskatchewan on the same weekend. So every third year here. They
had about 950 cars entered in the show and about 150 that come to spectate,
plus the public. They have a dinner and dance Saturday evening with about 2100
people. The caterer feeds all these in about 1/2 hour due to being organized.
It was all EXCELLENT.

We have river boat races coming up in 2 weeks. Aussies and Kiwis come here for
this. 120 MPH on the river!
