Dual-Fuel (Natural Gas/Biodiesel) Engines: Fundamentals, Performance and Environmental Impact

Abstract

This chapter briefly focuses on the use of biodiesel and natural gas in dual-fuel diesel engines, providing information about natural gas and biodiesel, and their characteristics, engine performance and exhaust gas emissions. The theoretical and experimental study provides analysis of a commercial compression ignition engine operating in dual mode with three fuels: natural gas, diesel and biodiesel at different load and biodiesel blends. On the basis of the results, the effects of air conditions, and the type and quantity of fuel used over the engine performance and environmental impact are reported, and viability of natural gas and biodiesel as alternative fuels for diesel engines is verified.

Allanblackia Oil: Phytochemistry and Use as a Functional Food

“…In addition, the demand for oils and fats from alternative plant sources has steadily increased, driven by several factors including: the demand for food from a steadily growing population with more financial resources, demand for biodiesel (food-fuel debate), price increase of some oils due to the rising costs of agricultural production, storage, and transport, fluctuations in oilseed yield due to poor climatic conditions in many parts of the world, and speculation [ 1 ]. In particular, due to the fact that more than 90% of the world’s biodiesel is currently produced from edible vegetable oils, significant research efforts are being invested in the discovery of alternative plant-based oil (both edible and non-edible) sources [ 2 ].…”
