... become a desirable replacement for the internal combustion engines (ICE) with its zero tailpipe emissions but poses practical problems when considering high-power density, long operating period applications like Class-8 trucks and heavy-duty off-road vehicles. A promising approach to reduce emissions...

...-propane blends as compared to gasoline. An increase in NOx emissions was detected along with a significant decrease in CO emissions. CO2 emissions declined for propane as compared to gasoline but increased with the addition of DME. Keywords: internal combustion engines, engine emissions, alternative fuels...

... range finding experiments and modeling presented in this work provide a basis for further investigation into the role of rich engine operation and in-cylinder turbulence to enhance ammonia combustion at low hydrogen blending levels. anhydrous ammonia emissions internal combustion engines spark...

..., a central component in engine development is the ignition system and in particular the spark plug. To increase the maintenance intervals of internal combustion engines, it is necessary to increase spark plug lifetime by reducing spark plug wear. The electrode materials used to date are often expensive...

... Abstract Fault Detection and Diagnosis (FDD) in internal combustion engines is an important tool for better performance, safety, reliability, and instrument to reduce maintenance costs. Early detection of engine faults can help avoid abnormal event progression to failure. This study is carried...

... Abstract The cycle-to-cycle variation of engine in-cylinder flow is critical for the improvement of performance for spark-ignition internal combustion engines. Proper orthogonal decomposition (POD), with its ability to extract the most energetic fluctuation structure, is widely used to analyze...

... Abstract The assumption of isotropic turbulence is commonly incorporated into models of internal combustion engine (ICE) in-cylinder flows. While preliminary analysis with two-dimensional velocity data indicates that the turbulence may tend to isotropy as the piston approaches TDC, the validity...
