Abstract. The relevance of the research is the intensity of noise emitted by lorries
depends on the regime of the vehicle movement. One of the main negative factors caused by
road vehicles is air pollution with exhaust gases. The article presents results for noise
caused by lorries and gas usage while the vehicle is accelerating. The subject of the study
is 4 lorries (MAN lorries, the total mass of which is ~18000 kg, whereas the lorry itself
weights ~8000 kg and has the power of 420-460 HP), and they also feature fuel recording
systems which are less than 5 years old. Research methodology. The level of noise emitted
by heavyweight transport vehicles is measured according to Lithuanian standard LST ISO
1996-2:2008 requirements. During the tests the noise levels of LA,eq, LC,eq, LC,peak were
measured. The tests were done 5 times each and the results are presented as arithmetical
averages. Fuel consumption is registered in vehicle data registration system. The researched
vehicles have to comply with environmental safety normative requirements; that the vehicle
carbon monoxide (CO), particulate matter (PM), nitrogen oxides (NOx), unburned fuel (HC)
and other hazardous substances contained in the combustion gases must not exceed the
prescribed limits. The results of the experimental studies show that EURO6 lorries (440 and
460 AJ) noise level is the lowest compared to the EURO4 and EURO5. After carrying out the
analysis of the caused noise and gas usage, it was found that noise pollution and gas usage are
higher without speed control system. The noise caused by lorries can be described in square
polynomial which defines the noise inclination change while vehicle is accelerating.
Scientific novelty of the research a complex research on noise and fuel consumption of
lorries by using and not using speed control system. Research idea and problem is to
achieve sustainable transport development objectives, in particular the reduction of
greenhouse gas emissions under the Kyoto Protocol. It is very important to find ways to
forecast and reduce transport noise pollution, while also reducing overall pollution, as well as
mitigating the impact on the global climate.,
Conclusion – after conducting a lorry noise and fuel consumption analysis, it was
determined that not using speed control system increases the noise and fuel consumption and
if the system is used both of these factors decrease drastically.
