Improving the environmental safety of road transport

In this article is investigated the influence of the re-equipment of road transport on natural gas on environmental safety, on the change in the content of emissions of toxic and carcinogenic substances with exhaust gases. Most traditional fuels do not provide low emissions, even though the requirements are constantly tightening. The high content of harmful substances in the combustion products of automobile engines has a negative impact on the environment and health of humankind. This makes us pay attention to alternative fuels, especially natural gas, and its applicability in road transport and the conditions for achieving the required level of environmental safety.

The comparison shows that, in terms of physicochemical characteristics, natural gas has advantages over traditional fuels. This justifies its applicability in road transport. An analysis of works in the fi eld of studying the amount and concentration of harmful substances in combustion products for engines completely converted to gas and gas diesel engines, shows that natural gas is the most environmentally friendly fuel. However, in order to achieve the required level of environmental friendliness, it is necessary to consider the type of transport, conditions, mode of operation, etc.

From the analysis, a conclusion was made about the ability of natural gas to provide the necessary level of environmental safety.
