Abstract

Energy is vital to the profitable growth of every nation and to stimulate new research. Only natural resources can meet the growing energy demand in recent years, biodiesel has become very interested in the energy as well as environmental advantages that it can be combined with mineral diesel fuel in any quantity. The research focuses on the study of the replacement of diesel with a safflower methyl ester. The engine tests shall be performed using the safflower methyl ester as fuel in the DI diesel engine. The combustion, emission and performance characteristics were studied using alternative fuels and mixtures. SAfflower Methyl Ester 80% (SAME80) and SAME100 have high heat release rates. Nitrogen oxides were higher by about 50%, carbon monoxide decreased by 10%, unburnt hydrocarbon was slightly higher and the thermal efficiency was higher for the SAME than for diesel fuel.

Highlights

  • The use of powerful diesel engines needs help in the future, as the fuel consumed is lower and potent greenhouse gases such as carbon dioxide are substantially reduced (Antolin et al, 2002)

  • The higher pressure of the SAfflower Methyl Ester (SAME) cylinder and its mixture during this time is due to its short ignition delay

  • In the case of the SAME blends and SAME, the pressure of the cylinder is closer to TDC compared to diesel

Summary

Introduction

The use of powerful diesel engines needs help in the future, as the fuel consumed is lower and potent greenhouse gases such as carbon dioxide are substantially reduced (Antolin et al, 2002). Several steps to encourage the conservation of petroleum resources have been taken (Murugan et al, 2008) These include improved refining energy production and increased transport fuel efficiency. The biodiesel fuel produced from safflower oil, which is not consumed by people in this The structure will be adjusted and compliant with the engine fuel injection system by decreasing the viscosity of safflower oil using the transesterification process. This process is used to transform bio-oils with fats and large ramified triglyceride molecules into smaller molecules with straight chains close to diesel fuel molecules. The torque is precisely measured using a loading cell-type pressure gauge to achieve output power
