Summary: The study investigates the impact of fuel injection timing on combustion and exhaust characteristics of a diesel engine using alcohol-diesel mixtures. Engine tests with fixed control parameters show that advancing fuel injection timing improves cylinder gas pressure and heat release rate. The use of alcohol-diesel blends reduces ignition delay, combustion duration, increases knocking tendency, and decreases CO and NH3 emissions. Changes in fuel injection timing effectively reduce CO2 and NOx emissions.

Summary: Dual-fuel combustion of ethanol and diesel in a high-compression ratio diesel engine showed improved combustion performance, reduced NOx and soot emissions, and increased net indicated efficiency compared to conventional diesel high-temperature combustion. The use of renewable bio-fuels such as ethanol in dual-fuel combustion can help reduce reliance on fossil fuels, lower greenhouse gas emissions, and enhance the viability of diesel engines for heavy-duty transport applications.

Summary: In this study, the hydrocarbon compositions of two types of diesel with different distillation range indexes were analyzed, and the effects on the combustion characteristics and exhaust emissions of three diesel engines were evaluated. The results showed that diesel with lower distillation range indexes can improve volatilization performance, shorten ignition delay time, and increase combustion efficiency, leading to reduced emissions of CO2, NOx, PM, and PN.

Summary: The present study addresses the challenges of utilizing methanol in diesel engines at high substitution ratios by adopting negative-valve overlap (NVO) and hot residual gases. The results show that NVO period, charge-air temperature, and MeOH lambda have significant effects on the combustion of methanol-diesel dual-fuel. The combustion in NVO mode achieved high net-indicated efficiency and low pollutant emissions.

Summary: In this study, waste fish oil was utilized to produce biodiesel and emulsion fuels, which were then tested in a diesel engine to evaluate performance and emissions. Through multi-objective optimization, the best emulsion fuel formulation was identified, resulting in simultaneous reduction of CO, unburnt hydrocarbon, and nitrogen oxide emissions compared to neat diesel fuel.

Summary: Hydrogen is a promising energy carrier that can be produced from renewable resources. It can be used in diesel engines with little modification and has the potential to improve performance and reduce emissions. However, there are challenges such as knocking combustion and higher nitrogen oxide emissions. This paper comprehensively reviews the effects of hydrogen on dual-fuel diesel engines and discusses opportunities and limitations. Suggestions for improving hydrogen-fueled diesel engines include reformulating pilot fuel, blending hydrogen with other fuels, adjusting engine parameters, and using exhaust gas catalysts.
