Alcohol-based fuels have shown high compatibility with spark-ignition (SI) engines, which require improvements in fuel efficiency and emissions reduction to meet modern environmental standards. While extensive research has been conducted on ethanol and other lower-order alcohols, there has been comparatively limited investigation into higher-order alcohols like butanol and pentanol as fuel alternatives. Previous studies on pentanol-gasoline blends in SI engines have demonstrated improved engine performance and reduced emissions.

- - The study focused on recovering oil from discarded lemon peel biomass and testing it as a gasoline substitute in engine blends at different volume ratios (10%, 20%, and 30%) using steam distillation for oil extraction.
- - Using an endoscopic visualization approach, the research found that a 10% lemon peel oil blend offered higher thermal efficiency and lower emissions, while premixed combustion produced better combustion characteristics, leading to increased cylinder pressure.
- - To enhance performance, a ceramic coating was applied to the piston using the micro-arc oxidation technique, which improved thermal efficiency by 3% and 4.69% for the 20% lemon peel oil blend compared to uncoated and pure gasoline engines, while also reducing hydrocarbon
This study focuses on effectively utilizing the biodiesel extracted from Azolla (third-generation biofuel), which is regarded as a renewable energy source, for fueling diesel engines. Biodiesel is unique due to its increased viscosity and different fatty acid composition, which proved difficult to attain better engine performance with a mechanical type injection system. This study expands on the previous investigation in modifying the fuel system when using Azolla biodiesel by using a common rail fuel injection system with wider injection flexibility.

Materials And Methods: Acute antihyperlipidemic effect was studied on chemically induced hyperlipidemic rat model. Treated groups received aqueous and methanol extract of leaves of respectively (1000 mg/kg; oral) whereas standard treated group received atorvastatin (60 mg/kg; oral) for 3 consecutive days.
