FIELD: transport.SUBSTANCE: invention relates to vehicle, in particular, truck or bus. Disclosed is vehicle with reduced noise emission, wherein enabled possibility of taking measures for, at least, temporary reduction of engine noise emissions to preferably specified by law value and/or below, wherein reducing engine noise emission is carried out by means of its operation control measures so, that engine electronic unit free or additionally assigned memory cells are switched to reduced noisiness mode, which acts at least temporarily, with higher fuel consumption and simultaneously with at least approximately constant power and rotation speed and reduces engine and/or drive noise emission, in particular, due to reduced noisiness mode decreases line pressure, injection is shifted to later point in time and/or enabling larger volume of fuel dosing partial amounts.EFFECT: technical result is reduced vehicle noise emission and simultaneously providing vehicle safety in traffic.20 cl |
