“…In investigating the performance of hydrogen/diesel reactivity-controlled compression ignition (H 2 /diesel RCCI) engines, a study by Duan et al [39] reveals that the indicated thermal efficiency (ITE) is significantly enhanced by employing a double direct injection (DDI) strategy over a single direct injection (DI) strategy, primarily due to improved fuel distribution and combustion conditions. The ITE increases notably when intake pressure is raised from approximately 100 to 120 kPa but decreases with further pressure enlargements due to reduced combustion efficiency and higher combustion temperatures.…”

In recent times, the significance of advancing road transportation technologies has notably increased. This is mainly driven by the escalating need for road transportation systems that are not only safe but also environmentally sustainable. Moreover, enhancing fuel efficiency in road vehicles (i.e., automobiles) holds the potential to contribute significantly to the reduction of a country’s economic vulnerability (i.e., improved energy security), by reducing the reliance on energy imports. While research reports and scientific journals provide valuable information on automobile fuel consumption, it is essential to continually update our understanding of the factors that influence it. This document aims to review and describe the various factors, both direct and indirect, that play a role in an automotive’s overall energy efficiency and fuel consumption.

“…Utilizing the double-injection technique as opposed to the single-injection strategy greatly improves the thermal efficiency and NOx emissions. It was discovered that the homogeneity of the direct injection fuel/air mixture is mostly responsible for RCCI’s NOx emissions . The RCCI engine has been found to be an efficient way to burn biofuel in a diesel engine with improved efficiency and reduced emissions due to the formation of layered charges with low reactive charges.…”

When the high-reactivity fuel burns, the low-reactivity fuel can observe the combustion temperature, which lowers heat loss through the piston.…”

Low-temperature combustion paired with the use of carbon-free ammonia and carbon-neutral biofuels is a novel approach for improving performance, reducing greenhouse gases, and reducing regulated emissions. Reactivity-controlled compression ignition (RCCI), a low-temperature combustion technology, dramatically reduces NOx and smoke emissions compared to traditional engines. Ammonia can be projected as a good transit fuel in the journey toward achieving net zero emissions and cleaner energy. This study examines the impact of ammonia energy premixing fraction (AEPF) (20, 30, 40, and 50%) as a lowreactive fuel (LRF) and algal biodiesel as a high-reactive fuel on the performance and emission characteristics of a single-cylinder, water-cooled 3.5 kW CI engine at a constant speed of 1500 rpm under various loading conditions. The research results indicate that the 40% ammonia share RCCI mode exhibited a reduction in carbon dioxide (CO 2 ) by 14.16%, nitrogen oxide (NOx) by 22.6%, and smoke by 42.1%, with an 11.5% improvement in thermal efficiency compared to the neat biodiesel-fueled conventional engine. Furthermore, the analytical hierarchy process (AHP) will be used in conjunction with the technique for order of preference by similarity to ideal solution (TOPSIS) of multiple criteria decision-making techniques to determine the optimal energy share in the RCCI combustion with the goal of achieving superior thermal efficiency and lower emissions. According to the AHP-TOPSIS study findings, AEPF40 is the best choice for all engine loads.
