“…In the area of increasing volumetric efficiency, Kubesh et al (1995) developed an electronically controlled NG fueled engine with a turbocharged-aftercooled engine controlled by an electronic control system. Tilagone et al (1996) found an increase up to 16% of thermal efficiency on a turbocharge spark ignition NG fuelled engine with multi point injection and optimized ignition timing with spark advance 200 higher running on stoichiometric A/F ratio.…”

“…Lean-burn natural-gas engines have lower maximum in-cylinder combustion temperatures [20] and hence higher thermal efficiency and lower hazardous emissions [21]. For the same thermal efficiency and air-fuel ratio, lean-burn natural-gas engines emit less CO 2 than diesel engines do; and the CO 2 emissions of natural-gas engines are 20% lower than those of gasoline engines of the same power [22]. Moreover, lean-burn natural-gas engines have lower NO x emissions under heavy load [23].…”

To meet the requirements of strict fuel consumption and emission limits, continuously increasing the thermal efficiency of an internal combustion engine and decreasing its exhaust emissions are the main challenges to its sustainable development within the automotive industry. Considering the competition with other zero-emission powertrain systems, such as vehicle batteries and fuel cells, the development of the internal combustion engine needs to focus on producing higher efficiency and zero emissions to meet the request of CO 2 reduction. This paper introduces two novel concepts for an internal combustion engine featuring high efficiency and zero emissions. Referred to as the argon power cycle engine fueled with either hydrogen or natural gas within an oxygen-argon mixture, its fundamentals and characteristics are expounded. This includes a method necessary to absorb carbon dioxide when natural gas is used as fuel instead of hydrogen.

“…In Spain, in most cities, the night distribution is prohibited except in specific cases with special and very restricted permits [47]. It is here where natural gas trucks have an advantage over conventional trucks, since due to the high octane number, methane has high resistance to auto-ignition that increases the compression ratio and besides generating great thermal efficiency [34,45,49], reduces the engine noise compared to the diesel combustion [50,51]. Therefore, the use of NG fuelled buses and trucks can reduce both the concentration of pollutant emissions and noise in urban areas [4].…”

Currently, energy consumption in the worldwide transport sector depends on 92.8% oil fuels. This dependency, among other problems, produces high levels of harmful emissions, which makes it necessary to increase the use of less polluting and more cost-effective alternative sources as natural gas. Furthermore, this alternative fuel must have autonomy, security and as optimal storage volume as the natural gas use in liquid state. This paper reviews the liquefied natural gas (LNG) use advantages over other fuels and analyses its introduction prospects in the transport sector in Europe, specifically in road freight transport. Natural gas (NG) technology for transportation is mature and extended through the compressed use (CNG) in urban light vehicles. However, CNG has not been attractive for extra-urban use mainly by the limited energy storage volume and difficulties for NG stations installation. For this problem, a LNG vehicle with the same fuel tank size could travel up to 2.4 times the distance compared with CNG. LNG in heavy-duty trucks reduces GHG emissions per kilometre up to 20% and almost 100% SOx and particulate matter, as well the noise in inner cities, compared to diesel trucks. An additional advantage is the operation cost savings that would give a LNG conversion payback between 1 and 3 years. The European Union has promoted the construction of LNG stations by the TEN-T programme and projects as the 'LNG Blue Corridors' in order to create a road network with LNG stations each 400 km. In addition, the world natural gas reserves would ensure the energy supply for the transport sector in Europe. Hence, the LNG for road freight transport is a potential alternative to replace the traditional fuels in the short to medium term.
