Performance Analysis of a Compression Ignition Engine Using Mixture Biodiesel Palm and Diesel

Abstract

The present investigation analyzes the performance of a Hatz diesel engine that has 912 cubic centimeters (cc), stationary type, two cylinders, an air cooled feature and B10 (90% diesel and 10% palm biodiesel), using a test bench to improve statistically the repeatability and reproducibility of the runs. The experimental reference tests were carried out under defined conditions at a fixed speed of 1800 revolutions per minute (rpm) and four load levels: 35%, 50%, 65% and 80%. The repeatability analysis was based on the technical standard NTC-ISO / IEC17025. The variables of torque, fuel consumption (FC), air consumption (AC) and exhaust gas temperatures (EGT) showed an increase related with the load increase, showing a lower variation of AC and emissions. With the mechanism’s implementation of attenuator of air blows, adjustment mechanism for rpm and preheating air chamber for intake manifold, it was observed that the rpm presented the lowest statistical variability. The variables that presented the highest Pearson correlation with respect to the FC are the CO2, NOX and O2, this is because the engine does not have the Common Rail system, which causes the fuel supply to not be injected accurately and uniformly, therefore the evaluation of performance of the engine could not be repeatable.

Torque Prediction Model of a CI Engine for Agricultural Purposes Based on Exhaust Gas Temperatures and CFD-FVM Methodologies Validated with Experimental Tests

“…The starting point for the development of such an acquisition system is the individuation of the engine parameters to gather and the assessment of the best data-collection methods to employ. Studies dealing with ICEs [26][27][28][29][30][31][32] usually focus on the following variables, which are the most representative of an engine and its operating conditions: Among all these parameters, this article will focus on the exhaust gas temperature (EGT). Indeed, EGT is one of the most meaningful parameters that can be acquired because it is representative of many phenomena occurring inside the engine (specifically, within the combustion chambers), and it is responsible for the correct operation of the devices located along the exhaust pipeline [33].…”

An Extensive Analysis of Biodiesel Blend Combustion Characteristics under a Wide-Range of Thermal Conditions of a Cooperative Fuel Research Engine

“…The transesterification reaction between triglycerides available in the feedstock and methanol is the standard method to produce biodiesels (a mixture of different fatty acid methyl esters-FAMEs) and glycerols [1,2]. A number of studies on utilizations of biodiesels and their 2 of 21 blends in compression ignition engines can be found in current literature [2][3][4][5][6][7][8]. Excellent reviews on the topic (both fundamental studies and biodiesels' utilizations) are provided in [9][10][11][12].…”

Experimental investigations into engine characteristics fuelled with hibiscus coconut biodiesel and its blends

“…An ANOVA analysis and a regression model were used to recognize the emission variables. At 50% load, air consumption is high compared to 80% load [25]. An open-source simulation tool has been developed to inspect the combustion, performance and emissions of different biodiesel.…”
