Abstract

Testing the air induction system on the toyota avanza K3-VE car with the thinkdiag easydiag 4.0 launch scanner aims to test the air induction system with car media whether the sensors and air induction system contained in the media work well. The method used in this research is to use a descriptive research method. The data collection used in this study aims to strengthen the results of research based on a theory, ideas of experts and observations. Based on the results of the tests that have been carried out on the Toyota Avanza K3-VE car with the Thinkdiag Easydiag 4.0 launch scanner at stationary, low, medium and high rotations, namely: 1) speed of 750.25 Rpm, the IAT sensor reads 89.6 degree F, the MAP sensor is 4.2 Psi and the TPS sensor reads 0%, 2) speed 1507.75 Rpm IAT sensor reads 95 degree F, MAP sensor 3.62 Psi and TPS sensor reads 2.75%, 3) speed 2042.52 Rpm IAT sensor reads 96.8 degree F, MAP sensor 3.62 Psi and TPS sensor reads 4.31%, and a speed of 3102.75 Rpm the IAT sensor reads 114 degree F, the MAP sensor 3.77 Psi and the TPS sensor reads 6.67%, from the data obtained above it can be concluded that the sensor and air induction system on the Toyota Avanza K3-VE function properly and can be used for private vehicles. effective daily.

Abstract

This study presents the testing of a 4 stroke motorcycle engine on the effect of power, torque and exhaust emissions. The process of improving engine performance is to expand the piston stroke and increase the volume of air in the intake and fuel lines to the engine combustion chamber. The process is carried out by overstroke which increases the step volume by increasing the length of the piston so that the compression ratio increases, and oversizes the combustion chamber with a larger size to 200 cc. The test was carried out at the Automotive Mechanical Engineering Workshop at the Dharma Patria Polytechnic, Kebumen. The test was repeated 3 times to get maximum results. The research objective is to improve engine performance seen from data on power, torque and exhaust emissions obtained from testing using a gas analyzer. In this study, direct testing was carried out on a gas analyzer engine with three conditions, namely at rpm 1000, rpm 2000 and rpm 3000. The test results with a modified gas analyzer engine show 41 ppm HC and 4.3% CO levels, these numbers indicate better exhaust gas levels.

Abstract

This study aims to describe the performance of the Honda Vario 125 engine that has undergone modifications to five main components, namely the piston, valve, camshaft, throttle body, and injector. Performance measurements were carried out to determine changes in torque and horsepower after the modifications were applied. The research method used was a quantitative descriptive approach with testing using a dyno test. The test procedure included engine preparation, tool calibration, and the implementation of a full dyno test from idle to maximum speed. The results showed that the engine was capable of producing a maximum torque of 31.36 N m at 3,507 rpm and a maximum power of 20.21 HP at 7,693 rpm. These values ​​indicate an increase in the engine's ability to produce power and thrust at certain speeds. Overall, this study provides an empirical description of the performance characteristics of the Honda Vario 125 engine after mechanical modifications
