City of Ramsey <br />15153 NOWTHEN BOULEVARD N.W., RAMSEYo MINNESOTA 55303 · (612) 427-1410 <br /> <br />June 12, 1981 <br /> <br />Lloyd, <br /> <br />I contacted 8gr. Mike Smith at St. Pa~l PDts Research and Development sec- <br />tion, on this date. He said they have installed the propane on ten squad <br />cars at a~tal cost of about 14, O00 dollars which includes the main propane <br />fi1] tank and a fence/slab. Cost per conversion was $1,095.OO and the tanks <br />and other equipment c~n, it is ~11 eged by the supplier, be easily switched <br />to another unit. The cost for bulk fill, at this time, is .555 per gallon <br />for this testing year. They are running the combination of gas/propane with <br />quick switching because they are unable to fill the propane after 2~O0 hrs. <br />and because propane looses operating pressure at very cold temperatures. The <br />efficiency and m~leage per gallon are less for propane but they expect longer <br />engine Life and there is no pollutant: emission. <br /> <br />They w41~ have no figures' or'statistics for several months and nothing really <br />conclusive for one year. I told Smith I woudd get back to him esrly on next <br />spring to get their conclusions on the experiment. <br /> <br />MGA <br /> <br /> <br />
