Opis:: Today’s world is facing the necessity of reducing air pollution. One of the alternatives is to limit pollution related to road transport by using CNG fuel. The European Union is imposing increasingly strict requirements regarding the cleanness of car fumes, and the Polish government is endeavouring to take actions aimed at reducing the pollution related to car use by planning the development of transport electromobility. In this article, the authors want to draw attention to methane as an alternative to traditional fuels. The article presents the results of a survey conducted among drivers, which regarded their readiness to use CNG-powered cars. The results indicate that while respondents appreciate the ecological value of this fuel, they are also worried about safety, which is contradicted by the analysis of CNG advantages and disadvantages.

Opis:: The safe use of gas fuel installations in vehicles is guaranteed by legal and technical aspects. These topics are included in this study. The regulations ensuring safety in the operation of the mentioned fuel systems serve as a solution for potentially hazardous situations. The components of propane-butane and CNG fueling systems are designed, manufactured and tested to maximize their safety of use. The regulations [6-8] define the guidelines for the arrangement and assembly method of the system components, and additionally, the assembly service itself may be performed only by an authorized workshop with granted permissions. Installations using gaseous fuels are safer than conventional fuels in the event of a collision or fire, as long as the user of the installation does not gross negligence in operation and maintenance. The article also discusses the context of the restriction in access to the car infrastructure for cars powered by gaseous fuels.

Opis:: The uncertainty in the supply of crude oil, increasing the number of vehicles and rising air pollution, especially in urban areas, has prompted us to look for alternative fuels. It is understood that using Compressed Natural Gas (CNG) in IC engines could be a mid-term solution to these problems. It is well established that CNG has better combustion characteristics and low emissions compared to conventional gasoline and diesel fuel. In the present study, an experiment was conducted to evaluate the engine performance and exhaust emissions using various percentages of CNG in dual fuel mode. CNG was mixed in the intake manifold’s air stream, and diesel was injected after the compression of the CNG air mixture. This paper presents experimental results of 40%,60%, and 80% CNG in the air stream. Engine performance and emissions are presented and discussed at a speed of 1200 rpm to 1500 rpm in steps of 50 rpm. The results of the experiments showed that adding CNG to diesel engines in dual-fuel combustion significantly impacted performance and emissions. Compared to single diesel fuel combustion, dual fuel combustion increases brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) at all CNG energy shares and engine speeds. Carbon monoxide (CO) and hydrocarbon (HC) emissions were increased, while nitrogen oxide (NOx) and smoke opacity were decreased in dual fuel combustion compared to single diesel fuel.

Opis:: This paper investigated the impact of the exhaust gas recirculation on the concentration of selected harmful chemical compounds from the AVL 5402 research diesel engine powered with diesel fuel (DF) and compressed natural gas (CNG). The engine was operated in the dual fuel mode. It means that the engine was conventionally fuelled by regular diesel fuel and simultaneously by CNG dosed into the inlet pipe. The necessary tests were carried out for the mixtures containing 30, 50 and 70% of CNG (by energy content) in the total chemical energy delivered together with diesel fuel (DF) into the combustion chamber. The research was conducted for the stationary conditions of the engine operation at 1200 rpm and constant 1004 Joules of a fuel chemical energy delivered in each cycle into the combustion chamber. Under such conditions, the impact of the EGR rate changed in range of 0–50% on the emissions of selected unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) as well as particulate matter (PM), was evaluated. The obtained results confirmed that the EGR system is effective in the reduction of the NOx formation for all tested fuel mixtures. Nevertheless, it was found that the addition of CNG combusted in the diesel engine generates more harmful pollutants in comparison with diesel fuel. However, in some cases the concentration of NOx as well as PM was comparable or lower. It suggests that the combustion of CNG in diesels allows achieving environmental benefits. In this case, further optimization of the engine fuel supply system is necessary.
