“…A solution can be extended diagnostics, involving the creation of a fuel delivery characteristic across the full range of working pressures and injection times (nozzle opening) [6,9,17]. It is essential to emphasize that this is a significantly more time-consuming process and is only available on advanced test benches, such as STPiW3 [12]. There is also the possibility of employing strictly scientific methods, the use of which is not always feasible in typical workshop conditions [3,14,18].…”

The article presents an original method for regenerating common rail injectors, which involves extending the standard diagnostic procedure with a phase of analytical calculations. These calculations were conducted based on the closed Newton-Cotes formula (commonly known as the trapezoidal rule), allowing for the estimation of the resulting fuel injection surface areas and their comparison with the manufacturer's reference. The presented example demonstrates that the proposed solution is particularly useful in challenging situations where a clear assessment of the injector's technical condition is difficult. Several other advantages have been highlighted, making this method suitable for application in laboratory and workshop conditions.

The Urban Heat Island (UHI) effect has become a prominent urban characteristic in the last few decades and brings significant changes to the local urban climate. Such changes have severe impacts on the lifetime efficiency and performance of “Critical Urban Infrastructure” (CUI). As CUI forms the backbone of vital urban systems and socio-economic processes, it becomes important to understand the various impacts of UHI on different CUI elements. The impacts of UHI on CUI have consequently become a prominent study area within the urban research domain. This study presents a systematic bibliometric review of 118 relevant articles published within the last decade (2012-2022) selected from a variety of indexed, scholarly databases. The articles mainly focused on developed regions and large urban areas. The review shows a consistent upward trend in the annual number of publications on UHI effects with a peak reached in 2020. Of the four major CUI groups studied for UHI impacts, built form and energy and communication (with a strong focus on increased energy consumption) are the most prominent topics in the current literature, followed by transportation, and water and sanitation. Research on other CUI elements is still quite sparse and significant efforts would be needed to identify the nature of UHI's impacts on these factors. This review highlights that the UHI impact on CUI is a developing research area that requires further attention and illustrates the state of knowledge and gaps present in current research. These findings provide a clear direction for future UHI impact studies.
