ABSTRACT

This paper represents the Performance operating characteristics of single cylinder diesel engineusing blend of chicken fat based Biodiesel at various loading conditions at constant speed. Wecompare the performance characteristics and smoke intensity of petroleum diesel with various

blends of chicken fat based biodiesel with petroleum diesel.

KEY WORDS: Biodiesel, chicken fat based biodiesel, alternative fuel, diesel engine,

performance characteristics, blend.

INTRODUCTION

Performance test were conducted on stationary single cylinder diesel engine by using chicken fatbased biodiesel blends with diesel fuel for no load to full load condition at constant speed. Thesetests were also conducted with conventional diesel fuel for comparison .Chicken fat basedbiodiesel is blended with petroleum diesel in proportion like 10%,15%,20%,25% and 30% theseblends are termed as CFBD10,CFBD15,CFBD20,CFBD25 and CFBD30 Engine Performance,Heat Balance sheet, using these blends and pure diesel have been evaluated and presented infollowing articles. All the Performance tests were conducted in the Automotive Power Plant lab,at Rajarambapu Institute of Technology, Sakharale, Islampur, Taluka-walwa and District-Sangli.

EXPERIMENTAL SETUPThe Performance test are conducted on a computerized single cylinder, four stroke, directinjection, water cooled diesel engine test rig. An engine indicator is fitted in control panel which

senses pressure and crank angle data interfaces with computer .Digital display of speed in RPMis indicated on engine indicator .The engine indicator is connected to COM port of computer.The engine and dynamometer were interfaced to a control panel ,which is connected to acomputer .Performance analysis software Engine soft version 2.4,supplied by test rig supplierApex Innovations Pvt. Ltd. was used for recording the test parameters such as fuel flow rate,air flow rate, temperatures, load etc and for evaluating the performance characteristics such asbrake thermal efficiency, brake specific fuel consumption, mechanical efficiency ,volumetricefficiency etc. The calorific value and density of the particular fuel was fed to the software forcalculating the above said parameters.

displays the process screen. Each test is conducted and data is stored at five different loads,conditions namely no load, 25%, 50%, 75% and full load. Engine is run for 15-20minits for onetest and data available is stored by log key at the end of time interval. Next tests are conducted.The tests are conducted in sequence like CFBD10, CFBD15, CFBD20, CFBD25, CFBD30 andwith pure diesel.

Engine Performance Analysis:

The performance of an internal combustion engine is mainly studied with the help of operatingcharacteristics. These characteristics obtained by using diesel and chicken fat based biodiesel insingle cylinder, four stroke diesel engine are discussed below.Measurements and Results

Measurement and results got by conducting trials using diesel and blends of chicken fat basedbiodiesel with the help of engine software are represented in the following tables 1to6.Theseresults are used to study various operating characteristics of engine such as specific fuelconsumption ,Brake thermal efficiency, torque and power etc. It also provided the necessary data

for calculating heat balance sheet.

The effect of chicken fat biodiesel and its blends and diesel fuel on engine torque are as shown inabove graph .The values of torque for fuel are given in test result tables .The engine torqueincreases with increasing loads for biodiesel and diesel. It is observed that the torque values ofbiodiesel blends are slightly lower than diesel at all load conditions. But there is no significantvariation.

2] Load Vs Brake Power for various blends of chicken fat biodiesel and Diesel.

The variation of brake power with load for chicken fat biodiesel blends and diesel is shown inabove graph. The values of Brake power for each fuel are given in test result tables .it isobserved that the brake power for chicken fat based biodiesel blends is slightly more than dieselat 25% load condition .CFBD10, CFBD15, CFBD20 has brake power is slightly more than diesel

at 50%,75% and at full load condition.

EMISSION MEASUREMENT RESULTS:

In this testing we use Bosch smoke meter to measurement of the intensity of smoke stain on

filter paper at full load for all samples of chicken fat biodiesel blends and diesel fuel are as

follows.

1] At 100% load Pure Diesel Emission sample paper obtain from Bosch smoke meter as shown

Bosch Smoke Unit no = 1BSU

2] At 100% load CFBD10 Emission sample paper obtained from Bosch smoke meter as shown

Bosch Smoke Unit no = 2 BSU





5] At 100 % load CFBD25 Emission sample paper obtained from Bosch smoke meter as shown

6] At 100% load CFBD 30Emission sample paper obtained from Bosch smoke meter as shown


From above sample observations smoke intensity for all blends is CFBD 25 and CFBD 30 are

slight more than diesel but within allowable range that nearly equal to diesel and in safe zone.

CONCLUSION

The Chicken fat based biodiesel with10%, 15%, 20%, 25%and 30%blend with petroleum diesel

are used in the conventional diesel engine without any modification in engine design or fuel

system, performance evaluation. To improve cold flow behavior during winter session only we

have use Magnesium based additives reduce the pour point, flash point and viscosity of chicken

fat biodiesel fuel .No any trouble was found during entire running period of engine. It wasobserved that the Performance operating characteristics that is Torque, brake power, frictional

power, indicated power, brake thermal efficiency, Indicated Thermal Efficiency, Specific fuel

consumption Volumetric Efficiency, and mechanical efficiency is nearly equal to petroleum

diesel at various loading conditions at constant speed for Chicken fat based biodiesel blend with

diesel at 10% [CFBD10], CFBD15, CFBD20, CFBD25and CFBD30 Biodiesel blends. Smoke

intensity we checked for all blends were found nearly equal to diesel sample. Due to the health

risks of waste chicken oils, it is considered as waste oil by the food industry. Therefore, waste

chicken fat is a cheap raw material and its low operating cost in biodiesel production make this

study a capable one for possible technological applications. Chicken fat biodiesel blended with

diesel fuel can be used as an alternative fuel in conventional diesel engines without any majormodification.
