More Information
Summary:An internal combustion engine includes a housing having a cylinder bore defining a bore diameter of 260 mm or greater, a fuel injector coupled to the housing, and a crankshaft rotatably coupled to the housing. A piston is coupled to the crankshaft and movable to increase a fluid pressure within the cylinder bore to an autoignition pressure, and includes a combustion face defining a plurality of valve pockets in a compound combustion bowl. Spray orifices in the fuel injector define a spray angle greater than 145°, and the combustion bowl has a diameter from 190 mm to 230 mm 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.
