Abstract

Fuel consumptioo is one of the parameter that measures the economical of a particular
engine. The PERODUA Viva l.OL engine has insufficient mileage-contribution for the
purpose of competition. Plus, the current engine has unbalance power-to-weight mtio,
unnecessary power for accelemtion and some pamsitic losses that affect the fuel
consumption. Therefore cylinder deactivatioo was introduced ro the engine ro provide more
mileage of the car. The technology of cylinder deactivatioo is not new and it is currently
being employed in many modem cars. Though the k.clmology has been proven by some car
manufacturer, it is worth ro try it in the other ways. The~ is ro implement the cylinder
deactivatioo on the engine by totally removing the pislon assembly and oonnecting rod in one
of the target cylinder. Then, it will be replaced by a balancer ro rednce the problem of engine
vibration. The scope of study restricli:d on the cuneut engine, modeling on some cumponents,
running some simple analysis on the JliUIIOillld system and experiment on the real engine The
process of study began with the underslanding of the engine bebavior towards the fuel
consumption and reviewed some available literatures such are current mahod of cylinder
deactivation, engine balancing theoly, pamsitic losses in the engine and power-to-weight
mtio. A quick calculat.ioo on power-ID-weigbt mlio was done ro enfun:e the need of cylinder
deadivalion. It showed lhat by pedorming cylinder deactivation, the ear ~ back its
original valne of power-to-weight mlio r.dher 1han •wa • y over-power. The involved
engine ampooeo1s were aankshaft, aooiing rod, pislon and pislon pin were modeled by
CA TIA for the purpose of analysis and designing the balaneer. Ia analysis by using ADAMS,
only the labal furoe develops-the middleuwoksl&aft was inv-stiVe" OptimiDtion of the
balancer weight was perfixmed ro find the best weight ro eater the cbdoped lalmd furoe.
The mlaocer has mass of 460g. Then, the , ... .._ was lilbiicaled and assembled on the
engine cranksbaft.. Other modilii:atioos had been dooe on olha- engine CiJIIIIW* •s, -ty
the intake and exhanst • amshaft, ignition system and inlake system. This is ro ensure the
engine is working as expected and nonnal.. From the cumploeted test. the Rl5IJit jpdM " 4lhat
cylinder deactivatioo n•• II ro impmve the ear mileage about II% fum the criginal car
mileage.
