Combustion, Performance and Emission Analysis of Diesel-Methanol Fuel Blend in CI Engine

Abstract

Due to serious environmental problems and the rising cost of fossil fuels, a lot of research work is going on for cleaner alternative fuels to improve engine performance and at the same time reduce emissions. Nowadays, methanol has emerged as a very strong alternative bio-fuel, which has a high potential to reduce subordination to crude oil and atmospheric pollution. Methanol also has inconsistent Physico-chemical and combustion properties, making it a more appropriate additive fuel than other available organic fuel additives for CI engines. Therefore, the aim of the present study is to review the impact of different methanol-diesel blends on CI engine combustion, emission, and performance characteristics. The combustion characteristics of the engine are evaluated by the heat release curve measured inside the cylinder pressure data under various engine operating conditions. Performance characteristics are also discussed for different methanol-diesel blends at various CI engine parameters. Smoke, CO, HC, NOx, and PM emissions of CI engine have been discussed with different engine parameters using methanol–diesel blends. The role of injection timing on engine emissions has been also discussed.
