Recently, the excessive use of diesel has caused a series of problems such as the exhaustion of fossil fuels and environmental pollution. More researchers have begun to study biodiesel. Biodiesel is a renewable alternative fuel with similar characteristics to traditional diesel, and can be used directly without changing the existing engine structure. However, biodiesel has a higher viscosity and lower calorific value and incomplete mixed with diesel, which will delay ignition, lower the ignition temperature, cause incomplete cylinder combustion, and increase exhaust emissions. In order to improve the above problems, the researchers found that the use of nanotechnology can improve the engine combustion performance and exhaust emission characteristics. This article reviews the effects of nanoparticles on the performance and emissions of biodiesel engines under different engine operating conditions, the use of nanoparticles as additives can improve engine combustion performance, increase cylinder pressure, promote combustion, and reduce HC and CO emissions.
