“…A single-cylinder compression ignition (CI) engine powered by hydrotreated vegetable oil in dual-fuel mode with natural gas and biogas was investigated experimentally. The results showed that port injection of biogas decreased particulate matter emissions by up to 76.8%, while natural gas reduced PM emissions by up to 83.1% …”

Advanced combustion concepts in compression ignition are emerging as one of the most promising solutions to reduce nitrogen oxides (NO x ) and particle emissions without sacrificing fuel efficiency. Among many advanced combustion concepts, reactive controlled compression ignition (RCCI) can achieve a wider working range. In this study, to implement RCCI operation, ammonia gas is introduced through the manifold as a low-reactive fuel, and biodiesel is injected directly as a high-reactivity fuel with a 40:60 energy ratio. The effect of biodiesel split ratio in a split injection strategy (pre- and main injections) is examined under varied load conditions, and the results are compared with ammonia/biodiesel single injection. Results indicate that the use of the 45% biodiesel split ratio at full load boosts the peak in-cylinder pressure and heat release rate and shifts the peak occurrence toward the top dead center (TDC). An increase in brake thermal efficiency (BTE) to 36.22% and reduced brake specific energy consumption (BSEC) to 8.75 MJ/kWh are 12.33% higher and 19.31% lower than ammonia/biodiesel single injection. Emissions of HC, CO, and smoke opacity were reduced to 50 ppm, 0.098% vol, and 15.6%, which are 34.21, 39.13, and 33.89% lower, while the emission of NO x was increased to 615 ppm, which is 36.06% higher than the single-injection ammonia/biodiesel RCCI combustion.

28 March 2023 the EU Council has adopted a regulation setting stringent carbon dioxide emission standards for new cars and vans. Under the new law, new vehicles with a 100 per cent reduction in carbon dioxide emissions will be able to be registered after 2035. The new EU legislation sets the following targets: a 55 per cent reduction in CO2 emissions for new cars and 50 per cent for new vans between 2030 and 2034 compared to 2021 levels; a 100 per cent reduction in CO2 emissions for both new cars and vans from 2035. This will result in only electric or hydrogen-powered cars and vans being able to be registered after 2035. The fuel omitted from the Fit for 55 packages within cars and vans is hydrotreated vegetable oil. According to the research carried out so far, it is possible to replace diesel with HVO fuel even without interference with the fuel injection control system. If an internal combustion engine is fuelled with HVO fuel instead of diesel, the greenhouse gas emissions can be reduced by up to 90 per cent. What is more, the technology for using HVO fuel has many more possibilities for reducing CO2 emissions, if only by refining the exhaust after-treatment process. The exclusion of this fuel from the Fit for 55 package raises serious doubts about the quality of the analyses based on which HVO fuel was not included in the Fit for 55 packages.

“…In terms of chemical structure, it consists of straightchain paraffinic hydrocarbons. The fuel is produced by hydrotreating vegetable oils, animal fats, or waste oils [17,24]. Advantages of HVO fuel over FAME fuel include high heating value and cetane value, lower turbidity temperature, and lower viscosity [5,16].…”

The article carries out a detailed analysis and evaluation of indicators related to the combustion process (pressure and temperature in the engine combustion chamber, heat release rate, heat release fraction) in a JCB 444 TA4i compression-ignition engine fuelled with diesel and hydrogenated vegetable oil (HVO). During the empirical tests, the operation of the exhaust gas recirculation (EGR) system was stopped and no other changes were made to the engine settings (factory settings were used). In the first stage, the empirical tests were carried out at speed characteristics on an engine dynamometer. Then, an experiment was carried out at the engine crankshaft speed corresponding to the maximum torque - which consisted of determining the indicators related to the combustion process at a constant mass flow of fuel: diesel and HVO fuel. This provided information on the effect of hydrogenated vegetable oil on the combustion process in relation to the diesel engine feed. The conclusions drawn from the empirical study can be used to develop guidelines to change the operating map of a compression-ignition engine when it is fed with hydrogenated vegetable oil.
