- 1The method involves recirculating two different amounts of exhaust gases at two different pressures from two exhaust passages (46, 48) of a cylinder (14) to two intake passages (42, 44), respectively. The fuel is directly injected into the cylinder, and the injected fuel is mixed with the exhaust gases in the cylinder. The mixture in the cylinder is combusted. An exhaust gas recirculation (EGR) cooler (82) is operated to heat and cool aircharge delivered to the cylinder through the intake passages during two conditions, respectively. An independent claim is also included for an engine system comprising an engine cylinder.
- 21. A method of operating the engine cylinder, wherein the recycling is carried out first amount of exhaust gas at a first pressure from the first discharge passage of the cylinder barrel in the first inlet channel and a second amount of recirculating exhaust gases at a second pressure, different from the first pressure, the second outlet of the second cylinder bore cylinder inlet channel.
