“…CNG as a vehicular fuel exhibits significant potential for the reduction of gaseous emissions and particle emissions [1,2,3,6,16,18,19,20,22,23]; such effects have been discussed and confirmed in previous studies [6,7,8]. CNG also has the potential to achieve reductions of greenhouse gas (GHG) emissions.…”

Natural gas is one of the most promising alternative fuels to meet the new stringent Euro 6 emissions regulations in the European Union, as well as the planned CO2 emissions reductions. For spark-ignition (SI) engines, bi-fuel fuelling equipment is widely available and engine conversion technology for European automobiles is well established, thereby facilitating usage of CNG in this engine type. This study investigates the implications of natural gas fuelling of a passenger car featuring a spark-ignition engine regarding the possibility of meeting Euro 6 emissions limits for gaseous pollutants. This paper presents an analysis of CO, THC, NMHC, NOx and CO2 emissions during testing of a vehicle on a chassis dynamometer, fuelled with CNG, in the context of the new Euro 6 emissions requirements. The analyses were performed on a Euro 5 bi-fuel vehicles with an SI engine equipped with an MPI feeding system operating in closed-loop control, a typical three-way-catalyst, and a heated oxygen sensor. The vehicles had been adapted by their manufacturer for fuelling with CNG by using additional special equipment mounted onto the existing petrol fuelling system. The vehicles tested featured a multipoint gas injection system latest generation. The tests subject to the analyses presented here were performed in the Engine Research Department of BOSMAL Automotive Research and Development Institute Ltd in Bielsko-Biala, Poland, within a research programme investigating the influence of alternative fuels on exhaust emissions from automotive vehicles with spark-ignition and compression-ignition engines.

“…The emission of CO is similarly a significant threat to the environment and the health of society. Carbon monoxide is emitted as a product of incomplete combustion of carbon fuels (e.g., petrol, diesel) [13,14]. These fuels are the main source of vehicle power and it is estimated that their combustion contributes to the emission of about 89% of CO emissions from anthropogenic sources in developed countries [15].…”

The problem of global warming and the related climate change requires solutions to reduce greenhouse gas emissions, in particular CO2. As a result, newly manufactured cars consume less fuel and emit lower amounts of CO2. In terms of exhaust emissions and fuel consumption, old cars are significantly inferior to the more recent models. In Poland, for instance, the average age of passenger cars is approximately 13 years. Therefore, apart from developing new solutions in the cars produced today, it is important to focus on measures that enable the reduction in CO2 emissions in older vehicles. These methods include the adaptation of used cars to run on gaseous fuels. Natural gas is a hydrocarbon fuel that is particularly preferred in terms of CO2 emissions. The article presents the results of research of carbon oxides emission (CO, CO2) in the exhaust gas of a passenger car fueled by petrol and natural gas. The emissions were measured under the conditions of the New European Driving Cycle (NEDC) test and in real road tests. The test results confirm that compared to petrol, a CNG vehicle allows for a significant reduction in CO2 and CO emissions in a car that is several years old, especially in urban traffic conditions.

“…The port injection NG produces negligible levels of CO, CO2 and NOx (Suga et al, 2000). In order to significantly reduce exhaust gas emissions, a port injection system was chosen by Czerwinski et al (1999Czerwinski et al ( , 2003, Hollnagel et al (1999Hollnagel et al ( , 2001) and Kawabata and Mori (2004), and the injectors and pressure regulator have been recently developed.…”
