The fine particles are mostly made from gases. There are four major origins for that gases which are responsible for these particles: rock (vaporized during combustion or casting), carbon from combustion, organic carbon, sulfates and nitrates. Take sulphur dioxide. It is created during engine combustion, but when it climbs into the atmosphere and mixes with rain it will become sulphuric acid. We all probably know very well what that will do- since it is highly corrosive and dangerous in concentration. The hard starting problems of diesel engines in below zero / freezing temperatures originate from two factors. One is the original cold air being drawn in to the turbocharger and compressed in to the engine?s cylinder head. The second is the fuel itself, can also be cold which sub zero / freezing temperature fuel is sprayed in to the cold engine?s combustion chamber, where it mixes using the cold air drawn thru turbocharger. The event takes place in English Bay at 10:00 PDT on four nights, beginning over a Wednesday and ending on a Saturday, over the bi weekly period during July and August. Each of the four performances have at least a three-day separation for preparation for the next competitor. Three companies representing their countries perform a twenty-five minute firework display set to music. A grand finale is performed on the last day by all the competitors.
