Performance and emissions characteristics of diesel engine running using biodiesel and its blends with kerosene compared to regular diesel

Abstract

I NCREASE of environmental problems and depletion of fossil fuels are the driving forces to promote biodiesel as an alternative fuel in diesel engines. In the present work, biodiesel was prepared by transesterification of waste cooking oil with methanol, its physical and chemical properties were measured and found to be within acceptable limits of standard specifications of regular diesel fuel. Performance and emissions characteristics of a diesel engine running using biodiesel (B100) and its blends with kerosene were then assessed and compared to those using regular diesel (D100). Two biodiesel blends of biodiesel with kerosene have been used in this study containing 25 and 50% by volume kerosene as (K25) and (K50), respectively. The used engine was a direct injection four stroke, four cylinders diesel engine and was run at two engine speeds being 1250 rpm and 900 rpm. The results showed that the composition of the exhaust gases of the engine running at both speeds was better using biodiesel instead of regular diesel and it has been improved further by blending biodiesel with kerosene. With respect to the brake thermal efficiency, it was found that the use of biodiesel instead of regular diesel reduced the thermal efficiency at 1250 rpm while the reverse was true at a lower running speed of 900 rpm. However at both engine speeds, the thermal efficiency can be improved by blending biodiesel with kerosene.

Combustion, Performance, and Emission Behaviors of Biodiesel Fueled Diesel Engine with the Impact of Alumina Nanoparticle as an Additive

“…It has been suggested that the optimal percentage is 15% since it resulted in the best engine performance [18] analyzed the role of 10% DEE into diesel-biodiesel-ethanol and dieselbiodiesel-methanol mixtures. Introducing DEE to a diesel-biodiesel-ethanol combination boosted the period of combustion, cylinder pressure, and BSFC while lowering the emissions of NOx and smoke, according to their findings [19]. Lee and Kim [20] reported that introducing DEE to diesel in different ratios has no influence on engine BTE.…”

Pengaruh Pencampuran Minyak Tanah Dengan Bahan Bakar Minyak Diesel, Biodiesel Dan Lainnya - Review

“…Zaher et al [18] juga mempelajari hal yang sama yaitu mencampur minyak diesel (D100) dengan minyak tanah dengan persentase 25% (K25) dan 50% (K50) pada kecepatan mesin 1250 rpm dan 900 rp m dengan beban yang berbeda. Hasil yang didapat bahwa konsumsi bahan bakar menjadi lebih rendah untuk campuran 25% dan 50% minyak tanah dibandingkan dengan biodiesel.…”

Design a prototype reactor for fuel oil production from waste tires using pyrolysis process

“…The fuel requirement for certain industries in the Kingdom of Saudi Arabia is huge, and have a broad fuel specification making the pyrolysis products a perfect fit. The two main applications of the liquid fuel produced from the process are utility companies producing both desalinated water, and electrical power, and cement companies [23][24]. The heavy fuel oil now used in both utilities, and cement companies are becoming in short supply, while the demands continue to increase due to increased need for water, electricity, and housing projects [23][24][25][26].…”
