LOW POLLUTION AUTOMOBILE ENGINE

A NEW INTERNAL COMBUSTION ENGINE CONCEPT IS PROPOSED THAT PROMISES TO REDUCE AIR POLLUTION SIGNIFICANTLY. THE ENGINE IS DESIGNED TO BURN VERY HIGH AIR/FUEL RATIOS AND THUS BURN AT LOWER MAXIMUM TEMPERATURE. THE BASIC IDEA IS TO USE TWO CYLINDERS FOR A COMPLETE ROUND OF FOUR CYCLES. IN A CONVENTIONAL ENGINE, ALL CYCLES (INTAKE, COMPRESSION, EXPANSION, AND EXHAUST) TAKE PLACE IN THE SAME CYLINDER. IN THE PROPOSED ENGINE THE AIR/FUEL MIXTURE IS DRAWN IN AND COMPRESSED IN A COOLED CYLINDER. THEN THE MIXTURE IS TRANSFERRED TO A LARGER, HOT, INSULATED CYLINDER WHERE THE AIR/FUEL MIXTURE COMES IN CONTACT WITH MANY RED HOT SURFACES AND HIGH TEMPERATURE COMPRESSED EXHAUST GASES AND THUS IS READILY IGNITED AND BURNED AT CONSTANT VOLUME. THE HOT GAS IS EXPANDED FULLY ON THE POWER STROKE AND THEN PUSHED OUT AS EXHAUST.
