Simulation and Experimental Validation: Waste Cooking Oil Transesterification Using Rushton and Elephant Ear Impellers
Research Output | Dar Al-hikmah Library | IIUM Only

The performance of two impellers (Rushton and Elephant ear) for waste cooking oil (WCO) transesterification were experimentally and numerically evaluated inside a unbaffled and baffled stirred tank reactor (STR). Three parameters (impeller bottom distance (C), speed, (N) and temperature) were investigated for fatty acid methyl esters (FAME) yield u

Possible Solution to Smoothen the Torque Curve of the Campro Engine
Research Output | Dar Al-hikmah Library | IIUM Only

The main objective of this project is to develop new solutions to smoothen the torque curve of the CAMPRO engine. The solutions should be cost effective, reliable and maintain the current emission level. The authors have performed an extensive study on the causes of the torque dip in CAMPRO engine. The CAMPRO engine experiences performance downfall

Experimental Investigation of the Swirl Effect on Campro Engine Using Designed Swirl Adapter
Research Output | Dar Al-hikmah Library | IIUM Only

Swirl is the rotational flow of charge within the cylinder about its axis. CAMPRO engine is a basic Double Overhead Camshaft (DOHC) which has a capacity of 1597 cc and installed with a total of 16 valves developed by Malaysian car manufacturer PROTON. The swirl adapter is theoretically placed inside the intake port of the CAMPRO Engine Model. The A

Investigation of non-Precious Metals for the Development of Low Cost Catalytic Converter
Research Output | Dar Al-hikmah Library | IIUM Only

This paper discusses the uses of non-precious metals in catalytic converters to bring down the cost without sacrificing the performance capability. Copper powder and nickel catalyst were chosen as the alternative catalysts to reduce the use of precious group metals (PGMs) platinum, palladium, and rhodium. Simulation by COMSOL has shown that Nickel

A Study of an Aftermarket Voltage Stabilizer for its Performance and Emission on Passengers Vehicle
Research Output | Dar Al-hikmah Library | IIUM Only

Heavy electrical load in a vehicle will consume more electrical power from the battery. Thus \vilt affect the performance of the vehicle and voltage stabilizer is created to cater this problem. This chapter shows the experimental investigation of the performance and the emission effect the vehicle using aftermarket voltage stabilizers. The experime

3-cylinder Gasoline Direct Injection as Opposed to 4-cylinder multi-Port Fuel Injection for Lower Fuel Consumption and Nox Emission
Research Output | Dar Al-hikmah Library | IIUM Only

The need for an engine that offers a low fuel consumption and good low-end torque grown for the past few years. The European environment protection agencies have drawn d<J the emission limits annually with emerging countries has started to adopt the European legislation. OEMs world wide have strived to meet the stringent regulation that made th

Solar Energy Management for Poverty Alleviation and Income Generating Activities
Research Output | Dar Al-hikmah Library | IIUM Only

Conventional modes of power besides running out are also aggravating the environment. New and renewable forms of energy are the need of the day. The abundance, inexhaustibility and non-polluting nature of the sun's energy to the earth, have made solar energy the right supplement for conventional energy sources, which are getting scarce and exha

Preliminary Investigation of Biodiesel Reactor Optimization Using Combine cfd-Taguchi Method
Research Output | Dar Al-hikmah Library | IIUM Only

Biodiesel is currently produced from food and non food oil sources. The process is significantly constrained by reaction kinetics and mass transfer. In the present article, preliminary investigation of the effect of reactor configuration on yield is carried out using waste cooking oil (WCO) at different reaction parameter. The Taguchi design, with

Biodiesel Production: a Mini Review
Research Output | Dar Al-hikmah Library | IIUM Only

The challenges faced in production of biodiesel from edible and non-edible oils via the transesterification process are discussed. Identified process parameters such as level of FFA, moisture content, Fatty acid composition varies for both edible and non-edible oil affects product quality, as a result, the process continues to be modified using com

Emotional Labor and Burnout Among Female Teachers: work-Family Conflict as Mediator
Research Output | Dar Al-hikmah Library | IIUM Only

With the increasing number of women in the workforce, there is a need to understand how the interrelationship between emotions and the demands of work and family influence their well-being. This study examined how emotional labor [surface acting (SA) and deep acting] and work–family conflict contribute to explaining variance in burnout (emotional
