Zusammenfassung:	An internal combustion engine (10) includes a housing (12) having a cylinder bore (14) defining a bore diameter (16) of 260mm or greater a fuel injector (24) coupled to the housing (12), and a crankshaft (28) rotatably coupled to the housing. A piston (50) is coupled to the crankshaft (28) and movable to increase a fluid pressure within the cylinder bore (14) to an autoignition pressure and includes a combustion face (62) defining a plurality of valve pockets (64) in a compound combustion bowl (66). Spray orifices (26) in the fuel injector (24) define a spray angle (94) greater than 145°, and the combustion bowl (66) has a diameter from 190mm to 230mm such that combustion of injected fuel yields a BMEP of 1600 kPa or greater and 0.25 grams particulate matter or less per bkW'h energy output of the internal combustion engine (10).
