Summary: Environmental problems and price instability have led to a growing interest in alternative energy sources. Biodiesel, a renewable substitute for diesel fuel, is a popular alternative fuel. This study focused on camelina plants as a potential source for biodiesel production. By transesterification, biodiesel was obtained from camelina oil, and the effects of adding high-carbon alcohol (n-pentanol) to biodiesel were studied in terms of engine performance and soot emissions. Results showed that the addition of 10% pentanol improved engine performance, but increasing the pentanol ratio had a negative impact. Additionally, the presence of pentanol's oxygen content was found to reduce smoke emissions.

Summary: This study investigated the effects of cetane number, pilot injection ratio, and pilot injection timing on the combustion and emission characteristics of a diesel engine. The results showed that increasing the pilot injection ratio and cetane number improved combustion efficiency and thermal efficiency, but led to higher CO, HC, and NOx emissions. Additionally, increasing the pilot injection ratio reduced the concentration of particulate matter.

Summary: The study explores the possibility of improving the performance of a Mesua Ferrea seed oil biodiesel run diesel engine by operating at different injection timings and load settings. The results show that retarding the injection timing at 20° bTDC improves fuel conversion efficiency, reduces exergy destruction, and lowers emissions. At injection timing of 20° bTDC for 100% load, the brake thermal efficiencies were found to be 26.11% and 27.76%, respectively, under biodiesel and diesel mode.

Summary: Adding multi-walled carbon nanotubes improves the thermal conductivity of 20 vol% palm oil biodiesel in fossil diesel (B20). Experimental results from a single-cylinder diesel engine show that the addition of MWCNTs reduces ignition delay, improves combustion efficiency and performance, and reduces CO and UHC emissions while increasing NOx emissions.

Summary: An investigation has been conducted on the use of biodiesel produced from palm oil and hydrogen gas in diesel engines. A single-cylinder diesel engine was operated directly on palm oil biodiesel and supplied with hydrogen at different flow rates. The study aimed to examine the combustion and performance characteristics of diesel engines fueled by hydrogen gas and palm biodiesel. Results showed that lower hydrogen flow rates resulted in the lowest ignition delay, and higher flow rates reduced knocking. Additionally, there was a significant increase in thermal efficiency and decrease in specific fuel consumption compared to biodiesel.

Summary: An improved heat transfer model was developed in AVL-BOOST to enhance the efficiency of a diesel engine fueled with biodiesel, incorporating a five-component biodiesel skeletal mechanism. The model accurately predicted the engine's performance characteristics, with errors less than 2% between experiment and simulation. The nozzle diameter, injection pressure, and injection advance angle were found to be significant factors in the injection system, highlighting the need to choose the injection rate reasonably.

Summary: The optimum conditions for producing refined crude palm oil methyl ester were investigated using the response surface method. Vacuum distillation was conducted to obtain refined crude palm oil with reduced free fatty acids, improving nutritional benefits and reducing chemical consumption. The purity of the methyl ester was studied by adjusting variables such as methanol content, potassium hydroxide concentration, stirrer speed, and reaction time. The results showed that the methyl ester had a purity of 96.91 wt% under the optimal conditions.

Summary: This study investigates the combustion characteristics and exhaust gas emissions of waste plastic oil (WPO) and distilled waste plastic oil (WPOD) fuels in a diesel engine. It is found that both WPO and WPOD fuels increase nitrogen oxide emissions compared to diesel fuel. However, they have lower smoke index due to their shorter carbon chains. Furthermore, their high calorific value and cetane index contribute to improved brake thermal efficiency and lower brake specific fuel consumption.
