Determination of Performance of a Semi-Adiabatic Diesel Engine with Plastic Oil

In light of the rapid depletion of fossil fuels, rising pollution levels from fossil fuels, and rising economic costs associated with crude oil imports, the quest for alternative fuels has become critical. Because they are renewable, vegetable oils and alcohols are viable alternatives to diesel fuel. Alcohols, on the other hand, have a low Cetane number (a measure of combustion quality), but vegetable oils have a high viscosity and low volatility, which causes combustion issues in diesel engines. Supercharging using plastic oil fueled trials were undertaken to increase thermal efficiency. Plastic oil has a calorific value comparable to diesel fuel, however because of its high viscosity, it may produce combustion issues due to injection issues. As a result, a semi-adiabatic diesel engine is required stainless steel crown and stainless steel gasket of an air gap insulated piston By threading the crown to the body of the piston, the gasket was kept in place between the body and the crown of the piston. At various levels of the engine’s brake mean effective pressure, performance characteristics such as brake thermal efficiency, exhaust gas temperature, and volumetric efficiency were determined. At full engine load, the brake specific energy consumption was measured. Variable injection time and constant injection pressure were used to analyse performance metrics. The electronic sensor was used to change the injection time. In compared to CE without supercharging, SADE with supercharging improves performance. The timing of injections further lowered pollutants.
