Climate change and severe emission regulations in many countries demand fuel and engine researchers to explore sustainable fuels for internal combustion engines. Natural gas could be a source of sustainable fuels, which can be produced from renewable sources. This article presents a complete overview of the liquefied natural gas (LNG) as a potential fuel for diesel engines. An interesting finding from this review is that engine modification and proper utilization of LNG significantly improve system efficiency and reduce greenhouse gas (GHG) emissions, which is extremely helpful to sustainable development. Moreover, some major recent researches are also analyzed to find out drawbacks, advancement and future research potential of the technology. One of the major challenges of LNG is its higher flammability that causes different fatal hazards and when using in dual-fuel engine causes knock. Though researchers have been successful to find out some ways to overcome some challenges, further research is necessary to reduce the hazards and make the fuel more effective and environment-friendly when using as a fuel for a diesel engine.

“…Natural gas (NG) is the fastest growing primary energy source owing to its advantages such as clean and efficient combustion, reliable and durable supply, energy and specific density, convenient and clean usage, and flexible implementations (vehicles, power generation plants, industrial and residential usage) [1], while liquefied natural gas (LNG) technology provides an economically feasible way to transport NG over long distances, currently accounting for nearly 30% of international trade of this resource [2]. In contrast to the traditional LNG supply chain, floating liquefied natural gas is an alternative [3] and the LNG-floating production storage and offloading (LNG-FPSO) is an effective and realistic way for exploitation, recovery, storage, transportation, and end-use applications when the gas source is located in a distant offshore ocean [4]. However, heat exchangers for LNG-FPSO should be more compact than those in onshore liquefaction plants due to the limited platform area [4].…”

In this study, the effect of axial heat conduction on thermal performance in a zigzag channel printed circuit heat exchanger (PCHE) with supercritical liquefied natural gas as the working fluid is studied by a numerical method under different conditions. The influence factors include Reynolds number, operating pressure, inlet temperatures of the cold side, and wall thermal conductivity. The results indicate that the axial heat conduction can greatly affect the thermal performance of the PCHE at low Reynolds numbers but decrease it at high Reynolds numbers for different working conditions. At the same average Reynolds number, the thermal performance of the PCHE decreases as the pressure increases, and the inlet temperature of 195 K provides the best thermal performance while the inlet temperature of 220 K is the worst among the three different inlet temperatures of the cold side. Furthermore, the reduction of wall thermal conductivity can improve the thermal performance of the PCHE due to the influence of axial heat conduction in the separation wall.

Floating liquefied natural gas is an alternative LNG supply method, and it is easy to produce, carry and import of the LNG as it is compared to the traditional LNG supply chain for the offshore reserves [3], and liquefied natural gas -floating production storage and offloading (LNG-FPSO) is a promising energy-efficient method compared to onshore NG treatment facility when the gas source is located in a distant offshore ocean [4]. A further development is the floating regasification units that transform LNG back to NG at the market location, and such units are called liquefied natural gas -floating storage and regasification units (LNG-FSRU).…”

In this study, the thermal and hydraulic performances of six different printed circuit heat exchanger (PCHE) configurations with supercritical liquefied natural gas as the working fluid are studied by a numerical method. Firstly, the thermal and hydraulic performances of the PCHE with airfoil fins are investigated at different operating pressures, which indicate that the PCHE with airfoil fins has better thermal performance but worse hydraulic performance when it operates at higher pressure condition. Furthermore, the effects of different PCHE configurations on the thermal and hydraulic performances are analyzed in detail. The results show that delta vortex generators (VGs) arranged upstream the airfoils can provide better thermal performance than VGs arranged downstream the airfoils, and the thermal performance of the common-flow-up configuration is not always better than the common-flowdown configuration. Finally, the overall heat transfer performance of PCHEs is evaluated by the volume goodness criterion under the same mass flow rate. The results show that the straight channel PCHE with front common-flow-up delta VG and airfoil fins has the best volume goodness factor among the six PCHE configurations.
