Analysis of variable valve timing intelligent mechanism of gasoline performance

Abstract

Abstract This study aims to determine the operational performance of the engine with the mechanism of the variable valve timing intelligent, testing the performance of the engine on the parameters of thermal efficiency, power, fuel consumption, and exhaust gas results. All tests weres conducted using the dynotest, and the fuel consumption was measured using the flowmeter technogerma. The data obtained will then be processed and the calculation of the performance of thermal and power efficiency using the calculation method using the Otto constant volume cycle. The results of testing the engine’s operational performance with the mechanism of variable valve timing intelligent are expected to get the results of the thermal volume constant indicator of 0.50-0.70, the value of the generated power of 69kW at 6000 rpm, torque of 122 at 4200 rpm, and the results of material consumption specific fuel below 270 g/kW.h or around 0.200-0.220 kg/PS.
