Abstract

The impact of changing in air intake temperature assumes a significant part to the spark ignition engine. Consequently, expanding or diminishing of surrounding temperature on the earth these days will impact the performance and the quality of air especially related to spark ignition engine. Thus, this study will be led to decide the warmed worth of air intake temperature that impact for better engine performance and emission. Spark ignition engine also called heat engine depends on such a great amount to the progressions in temperature. This proposal will present the trial result on the performance of spark ignition engine at various heated air intake temperatures on four-stroke four-cylinder spark ignition engine. It also researched the level of emission delivered to the climate because of expansion in air intake temperature. In this study, to measure the Torque value and calculate the Brake Power value the four-stroke four-cylinder spark ignition engine (Satria neo-1.6L G Manual) were tested using Chassis Dynamometer (DYNOMITE). While the exhaust emissions percentage values of CO2 and HC was recorded by using EMS gas anayzer. The data was taken under three different gears (gear 2,3 and 4) at varying speed (1500,2000,2500,3000 and 3500 rpm) and intake temperature range (55℃~60℃). Based on the data and result recorded increase in temperature do increase the engine performance in terms of brake power and torque but also increase the emission percentage as well.
