“…In general, higher ethanol percentages or other alternative fuels result in lower emissions [33][34][35][36][37][38][39][40][41]. Even further reductions are expected with other combustion concepts [42] or hybridization [43]. Thus the emissions of future mopeds and motorcycles should be closely monitored.…”

The Euro 4 regulation, applicable since 2016 for L-category vehicles (i.e., two and three-wheelers, and mini cars) reduced the emission limits, but also introduced a new cycle, the WMTC (World Harmonized Motorcycle Test Cycle). The emission studies of Euro 4 motorcycles are limited, and most importantly there are no published studies comparing the results of different laboratories applying the new cycle. In this study we compared the particle and gaseous pollutants of one Euro 4 motorcycle measured in two laboratories in 2017 and 2020. The gaseous pollutant results had a variance (one standard deviation of the means) of 0.5% for CO2, 4–19% for CO, NOx, HC (hydrocarbons) and SPN (Solid Particle Number). The particulate matter mass results had higher variance of 50–60%. Additional tests with open configuration to mimic dilution at the tailpipe gave equivalent results to the closed configuration for the gaseous pollutants and SPN. The total particles (including volatiles) had significant differences between the two configurations, with the closed configuration giving higher results. The main conclusion of this study is that the new procedures have very good reproducibility, even for the SPN that is not regulated for L-category vehicles. However, the measurement of total particles needs attention due to the high sensitivity of volatile particles to the sampling conditions.

The principle of a HCCI engine is to inject a mixture of fuel and air into the cylinder and allow it to self-ignite under a high compression ratio. Unlike traditional gasoline and diesel engines, the mixture in the HCCI engine is homogeneous and does not require an ignition system to ignite it. The air-fuel mixture in the cylinder is burned completely by compressing. It makes effective use of fuel. The structure is simpler than a conventional internal combustion engine. HCCI engine has a huge application prospect in many fields. Among them, the automobile is one of the biggest parts. However, some applications have not been widely used. Although the HCCI engine has so many advantages, as this study has discussed, many of its drawbacks are still serious, such as the difficulty in controlling the parameters in the combustion and work process, resulting in the theoretical process being difficult to realize fully. The stringent environmental constraints of HCCI engines, the scarcity of suitable fuels and the significantly lower lifetime of HCCI engines than conventional engines pose significant obstacles to their practical use. This study presents the idea of using artificial intelligence system-assisted control system to accurately control HCCI engines in real time, which has shown great potential in HCCI engine misfire detection and HCCI engine initial burn time prediction.

User’s determination of a proper method for quantifying fuel consumption of a passenger car with compression ignition engine in specific operation conditions

The present research concerns itself with measuring and evaluating fuel consumption of compression ignition engine in passenger cars by a variety of methods and in different operating modes. The main objective is to compare different procedures for the cars’ fuel consumption experimental investigation in the point of view of their accuracy. The measurements were carried out on Citroen Berlingo motor vehicle. The very research is focused on implementing and evaluating the discussed consumption by three different methods, namely calculation from consumed fuel volume measured on fuel station flowmeter (pump stand), recording the data from an on-board computer and obtaining data from a specific application. Given that a certain driving style has a significant impact on fuel consumption, particular examinations were conducted in three operating modes, where the very journeys were made in order to measure the consumption in relation to an economic, a regular and a dynamic driving style. The vehicle being tested was driven on four specified routes that varied in their length, maximum permitted velocity on individual sections and number of intersections, or a citymotorway ratio. To this end, the experimental research resulted in putting toward recommendations and procedures, including appropriate methods, to ensure reliability of fuel consumption measurements with respect to the diverse operating modes of passenger cars.
