Emissions From a Medium-Duty Crdi Engine Fuelled With Diesel-Biodiesel Blends

Abstract

In the present work, biofuels produced from different raw fatty materials have been proposed as a dominant fuel component in biodiesel-diesel fuel blends. Biofuels were produced from pork lard and rapeseed oil by alkali transesterification using methyl alcohol. Blends of biofuels in volumetric proportions of 60 and 80% of the biocomponent and the remaining part of the conventional fuel were used in a compression ignition engine designed for medium-duty vehicles. The experiments were conducted at two engine rotational speeds (1500 and 3000 rpm, respectively) and a set of load conditions (50, 100, and 200 Nm, respectively). The tests focused on engine efficiency parameters (brake-specific fuel consumption and brake fuel conversion efficiency) as well as exhaust gas emissions (hydrocarbons, carbon monoxide, and carbon dioxide were determined). The obtained results indicate that blends containing biocomponents produced from pork lard were characterized by superior fuel consumption and efficiency results, compared to blends containing biocomponents produced from rapeseed oil. In terms of exhaust emissions, biocomponents produced from pork lard were also characterized by lower emission of all of the examined components compared to rapeseed methyl ester-diesel blends. This study proposes that fuel components obtained from custom (animal) raw-fatty material can be an effective substitute for commonly used rapeseed oil methyl esters.

Evaluating the Influence of Cetane Improver Additives on the Outcomes of a Diesel Engine Characteristics Fueled with Peppermint Oil Diesel Blend

“…Life cycle emission of CO 2 is lower for eco-friendly biofuels, which can help to decelerate global warming [3]. Many researchers tried various biofuels, since the oil obtained from waste fatty acids, animal fat, vegetables and other biodegradable products have physical and chemical properties very similar to diesel fuel [4]. However, direct vegetable oil usage in diesel engines is not gaining importance due to its unfavourable properties such as high viscosity and low boiling point.…”

Overview of Energy Harvesting Technologies Used in Road Vehicles

“…Research on the impact of biodiesel used in diesel engines with various fuel systems was studied also by [60,79]. In terms of fuel blending, bioethanol with gasoline [80,81], bio-ethanol with diesel [82,83], ethanol with diesel [84], biodiesel-ethanol and biodieselmethanol blends can be used [85].…”

A Method for Assessing the Technical Condition of Traction Batteries Using the Metalog Family of Probability Distributions

“…Despite the growing interest in electric vehicles, alternative fuels for piston combustion engines are constantly being developed. Gas fuels such as LPG for gasoline [15,16] and diesel engines [17,18], NG [19], CNG and LNG [20][21][22], various biofuels [23,24], and biodiesel from various raw materials [25][26][27][28][29][30] or hydrogenated vegetable oil (HVO) [31,32] are the examples of this progress. Another expanding field of research is related to fuel cells [33,34].…”
