Knowing this, the Komatsu engineers used a new engine (the SAA6D125E-5) that for lower emissions and less noise. <\/span><\/p>\n<blockquote><p><span style=\"font-weight: 400;\">\u201cBy employing a new engine (whose rated speed is 5% lower than that of the conventional engine), an electronically-controlled hydraulic fan, air suction ducts in the engine hood and side covers, the ambient noise was reduced significantly.\u201d<\/span><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">In fact, using these techniques (and mounting the engine to the main frame with rubber cushions) made the new model emit 10 dB less ambient noise, compared with the former model.
