A METHOD OF MIXING IN A COMBUSTION CHAMBER OF AN INTERNAL COMBUSTION ENGINE AND A SPARK-IGNITION DIRECT-INJECTION STRATIFIED FUEL-AIR CHARGE INTERNAL COMBUSTION ENGINE

摘要

The invention represents a method of mixing in a combustion chamber of a spark-ignition direct-injection stratified charge internal combustion engine a fuel-air mixture being ignited by a spark plug (5), the method comprising: the injection, in the compression stroke, of fuel to the combustion chamber charged with air,- fuel spraying onto the surface of the combustion chamber disposed in a cylinder head; the organization of air charge motion, wherein the fuel is injected and sprayed so that there is produced a cone-shaped fuel spray, which consists of a cone-shaped body of the spray cone and of a cone-shaped cavity within the body and which is directed so that a spark plug gap is inside the cavity and the motion of the air charge is directed uniformly from all sides along the combustion chamber surface towards the spark plug electrodes (6). Another aspect of invention is engine according to method of the invention.
