Special Issue Information

Internal combustion engines are widely used in the transportation sector, including road transport, off-road transport, and marine transport and so on, due to their reliability, adaptability, and higher combustion efficiency. The use of a large number of internal combustion engines to generate power has led to the depletion of fossil fuels, an increase of global warming, and an increase in harmful emissions. To address concerns about the global energy crisis and warming, it is of great importance to discover alternative fuels that are required for internal combustion engines and minimize their emissions. Biofuels are considered a cleaner fuel for internal combustion engines due to their renewable properties and the reduction of fossil CO2 discharge. This Special Issue aims to publish a critical review and an in-depth technical research paper on internal combustion engines using biofuels, with a main emphasis on combustion and emissions. 

The topics of interest for this Special Issue comprise, but are not limited to, the following: 

  • Recent developments in internal combustion engines
  • The exploration of advanced biofuels
  • Advanced conversion techniques of biofuels
  • The application of biofuels in internal combustion engines
  • Emission control strategies
  • Pollutant formation models
  • Low-temperature combustion technology
  • Fuel injection and spray formation
  • Premixed and diffusion combustion

In the current work, an effort is made to study the influence of injection timing (IT) and injection duration (ID) of manifold injected fuels (MIF) in the reactivity controlled compression ignition (RCCI) engine. Compressed natural gas (CNG) and compressed biogas (CBG) are used as the MIF along with diesel and blends of Thevetia Peruviana methyl ester (TPME) are used as the direct injected fuels (DIF). The ITs of the MIF that were studied includes 45° ATDC, 50° ATDC, and 55° ATDC. Also, present study includes impact of various IDs of the MIF such as 3, 6, and 9 ms on RCCI mode of combustion. The complete experimental work is conducted at 75% of rated power. The results show that among the different ITs studied, the D+CNG mixture exhibits higher brake thermal efficiency (BTE), about 29.32% is observed at 50° ATDC IT, which is about 1.77, 3.58, 5.56, 7.51, and 8.54% higher than D+CBG, B20+CNG, B20+CBG, B100+CNG, and B100+CBG fuel combinations. The highest BTE, about 30.25%, is found for the D+CNG fuel combination at 6 ms ID, which is about 1.69, 3.48, 5.32%, 7.24, and 9.16% higher as compared with the D+CBG, B20+CNG, B20+CBG, B100+CNG, and B100+CBG fuel combinations. At all ITs and IDs, higher emissions of nitric oxide (NOx) along with lower emissions of smoke, carbon monoxide (CO), and hydrocarbon (HC) are found for D+CNG mixture as related to other fuel mixtures. At all ITs and IDs, D+CNG gives higher In-cylinder pressure (ICP) and heat release rate (HRR) as compared with other fuel combinations. Full article

Biofuels are important additives to conventional fuels in combustion engines of the transport sector, as they reduce atmospheric emissions and promote environmental-friendly production chains. The mechanical and thermal performance of a PT6A-61A engine on a test bench of the Colombian Air Force operating with blends of JETA-1 and Biodiesel up to 25% volume values of substitution is evaluated in this work. Experimental results show that blends are operationally reliable up to 15% volume content. In that range, the engine operation is not compromised in terms of response variables. Moreover, experimental properties of fuel blends show that the freezing point—which is the most critical variable, does not comply with aeronautical regulations. The system dynamics are subject to several variations in the test parameters, which mainly affected fuel flow, Inter-Turbine Temperature (ITT), and engine performance. A Principal Component Analysis (PCA) is performed over the experimental results to quantify possible disturbances on the bench measurements. This is based on the fact that the study is restrained to stationary test bench conditions. Full article
