Studying Performance and Combustion Characteristics of Biodiesel from Walnut Oil by Using RK Diesel Analysis

There is a strong global interest in producing alternative and renewable engine fuels due to factors including declining oil supplies, rising oil costs, exhaust emissions' damage to the environment, and global warming. The application of biodiesel as a substitute fuel is taken very seriously. The goal of the study is to find the ideal compression ratio for biodiesel made from used cooking oil in various amounts. The process is greatly impacted by the compression ratio, which also offers an exceptional level of motor performance control. For traditional internal combustion engines, the compression ratio is fixed, leading to a compromise between the conflicting needs. A variable compression rate engine may be used to study the compression impact of various biodiesel mixes under various loads. The edible walnut is utilized in this effort to produce biodiesel. Numerous experts have experimented with different types of biodiesels in different diesel engines. The goal of the current study is to compare the performance, combustion, and emission characteristics of biodiesel mixes with those of standard diesel. Direct injection diesel engine combustion characteristics are simulated using the DIESEL-RK
