Summary: The article discusses the use of a catalyst in a diesel engine to reduce exhaust emissions. The efficiency of an internal catalyst was compared to an external reactor through exhaust emission measurements in different stages. The results showed that the in-cylinder catalyst is most efficient during cold engine start, especially in urban driving. The proposed solution can improve combustion quality in hybrid vehicles and be retrofitted in traditional vehicles for emission class improvement.

Summary: Automobile pollution has caused significant environmental degradation and climate change. Research is being done to find alternative fuels that can improve efficiency and reduce emissions. This study focuses on the performance and emission characteristics of a DICI-VCR engine using ethanol and Al2O3 nanoparticle blended biodiesel. The results show a decrease in performance and an increase in certain emissions compared to pure diesel.

Summary: This study investigated the impact of a helicoidally shaped copper duct on the combustion characteristics and particulate emissions of a 2.2 L Direct Injection High Pressure Common Rail (DI HPCR) diesel engine. The copper duct, powered at 12.5 V by magnetic coils, was installed on the fuel line before the high-pressure pump. The results showed a 28% reduction in soot emissions when the device was connected to the fuel line, primarily due to a copper-mediated oxidizing effect. A comparison study with a Teflon duct revealed that the magnetic field has no significant effect on combustion and emission characteristics if no metal is leached into the fuel.

Summary: The study focused on producing biodiesel from waste cooking oil using two types of catalyst and blending it with net diesel fuel for use in a diesel engine. The results showed that the heterogeneous catalyst led to a shorter production time but higher energy consumption. Blending biodiesel with diesel slightly improved engine performance and combustion behavior.

Summary: The study found that adding clean fuels such as methanol, ethanol, and n-heptane to diesel can effectively reduce emissions, improve fuel economy, and increase maximum brake thermal efficiency. Results from using blended fuels showed a significant decrease in CO2 emissions and a reduction in HC emissions with an increase in engine load.

Summary: This study compares the combustion characteristics of conventional diesel, reactivity controlled compression ignition (RCCI), and dual direct injection (DI2) combustion modes. The results show that while both DI2 and RCCI modes are successful in reducing NO x and Smoke Opacity, they also result in higher CO and unburned HC emissions.

Summary: In this study, the performance and emissions of conventional diesel fuel, pure Jatropha biodiesel, Jatropha-butanol blended fuel, and Jatropha biodiesel with fumigated butanol were tested in a single-cylinder diesel engine. The results showed that butanol fumigation improved the properties of Jatropha biodiesel and provided a better overall performance compared to blended fuel and neat Jatropha biodiesel.

Summary: Polyoxymethylene dimethyl ethers (PODE) can enhance the miscibility of ethanol/diesel blends, while the pilot injection strategy can improve combustion noise and NOx emissions. The study shows that optimizing the pilot injection strategy can improve the thermal efficiency and reduce hazardous gas emissions of the blends.

Summary: The study explores the impacts of blending, fumigating, and combined fumigating+blending methods on engine combustion and cyclic variability parameters compared to diesel method. It is found that blending method has slightly longer overall combustion progression, fumigating method has minimal effect, and both blending and fumigating methods increase COVIMEP.
