Japanese Patent JP2003500592
Kind Code:
A
Abstract:
In a method for the operation of a four-stroke reciprocating piston internal combustion engine with alternating compression. ignition and spark ignition, fuel is injected directly, fresh charge is delivered and combustion exhaust gas is led off. At low and medium partial load a partially homogenized, lean basic mixture of air, fuel and retained exhaust gas is formed for the compression ignition, and at higher partial load and at full load a homogeneous, stoichiometric mixture is formed for the spark ignition. Further features include exhaust gas retention, a build-up of exhaust gas and activation injection into the retained exhaust gas. For a smooth transition between the two operating modes, in addition to the co-ordinated interaction of exhaust gas retention, build up of exhaust gas, restriction of the fresh charge, and of the ignition advance angle in spark ignition, together with the quantity and the timing of the fuel injection, use is also made of exhaust gas recirculation.
