1. emissions and ignition timing? (score: 1): Author: "John F Sandhoff" <sandhoff@csus.edu>; Date: Mon, 23 May 2005 10:59:51 -0700; Any smog gurus out there? Please, no guessing on the following. I need to know what really happens :-) What is the effect on unburned hydrocarbon emissions (HC) if the timing is retarded? Later (68+); /html/datsun-roadsters/2005-05/msg00433.html (7,320 bytes)
2. emissions and ignition timing? (score: 1): Author: thomas walter <roundrocktom@yahoo.com>; Date: Mon, 23 May 2005 11:51:40 -0700 (PDT); Remember the "trick" Nissan used was to set the timing at 0 BTDC, but with air injecting into the exhaust manifold. This allowed for UNBURNT fuel to be post ignited after combustion. At that time (1; /html/datsun-roadsters/2005-05/msg00436.html (7,651 bytes)

But here it is again: It tests the effects of tuning the timing and mixture on emissions.
