“…RCCI/dual fuel modes have been studied by developing a phenomenological 0D combustion model. The combustion model is capable to handle both a combustion mode based on a chemistry progression (RCCI with TKI) or one on a fractal-based flame propagation (dual fuel), locally initiated by auto-ignition of high reactivity fuel [ 12]. Model capabilities can be appreciated by the results obtained in collaboration with Wartsila (Fig.…”

“…The lowreactivity fuel reaches premixed conditions (homogeneous mixture) prior to the start of combustion, whereas close to the TDC, the in-cylinder mixture consists of areas with high and low reactivity [23]. RCCI engines achieve higher efficiency [24] and lower emissions compared to engines operating with other LTC methods [25][26][27][28]. On the contrary, PCCI includes the high-reactivity fuel injection close to TDC (-30 • CA to 0 • CA) to allow for more effective combustion control.…”

Methanol has been identified as a transition fuel for the decarbonisation of combustion-based industries, including automotive and maritime. This study aims to conduct a critical review of methanol combustion in compression ignition engines and analyse the reviewed studies’ results to quantify methanol use’s impact on engine performance and emissions characteristics. The diesel and diesel–methanol operation of these engines are comparatively assessed, demonstrating the trade-offs between the methanol fraction, the key engine performance parameters, including brake thermal efficiency, peak in-cylinder pressure, heat release rate, and temperature, as well as the carbon dioxide, carbon monoxide, nitrogen oxides, and particulate matter emissions. The types of the reviewed engines considering the main two combustion methods, namely premixed and diffusion combustion, are discussed. Research gaps are identified, and recommendations for future research directions to address existing challenges for the wider use of methanol as a marine fuel are provided. This comprehensive review provides insights supporting methanol engine operation, and it is expected to lead to further studies towards more efficient use of methanol-fueled marine engines.

“…Numerical simulations, such as 0D and 3D-CFD models, can be appropriate tools to reproduce the unconventional combustion phenomenon, as deeply investigated by the authors in their past works [15][16][17], thus, supporting also the development of HCCI engines. In this regard, the main tasks of the numerical models are the deployment of optimal combustion control strategies, engine calibration, and engine design.…”

Homogeneous charge compression ignition is considered a promising solution to face the increasing regulations imposed by the legislator in the transport sector, thanks to pollutant and CO2 emissions reduction. In this work, a quasi-dimensional multi-zone HCCI model integrated with 1D commercial software is developed and validated. It is based on the control mass Lagrangian approach and computes the mixture chemistry evolution through offline tabulation of chemical kinetics (tabulated kinetic of ignition). Thus, the simulation can predict mixture auto-ignition with reduced computational effort and high accuracy. Multi-zone schematization mimics the typical thermal stratification of HCCI engines, controlling the combustion evolution. The model is coupled to sub-models for pollutant emissions estimation. Initially, the tabulated chemistry approach is validated against a chemical kinetics solver applied to a constant-volume homogeneous reactor, considering various fuel blends. The model is then used to simulate the operations of four engines using different fuels (hydrogen, methane, n-heptane, and n-heptane/toluene/ethanol blend), under various boundary conditions. The model predictivity is demonstrated against pressure traces, heat release rate, and noxious emissions. The numerical results showed to adequately agree with measured counterparts (average relative error of 1.3% on in-cylinder pressure peak, average absolute error of 0.95 CAD on pressure peak angle, average relative error of 8.4% on uHCs emissions, absolute error below 1 ppm on NOx emissions) only adapting the thermal stratification to the engines under study. The methodology proved to be a reliable tool to investigate the operation of an HCCI engine, applicable in the development of new engine architecture.
