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.
