Its function is to optimize the airflow process to the throttle body or carburetor. However, many users or people tend to overlook the significance of improving engine performance by varying the model or replacing the velocity air intake system itself. One common issue is the diameter and shape of the airflow model, which can affect the power, torque, and exhaust emissions produced. Installing a velocity air intake system is one approach to achieve an efficient air delivery process into the combustion chamber. In our research conducted using a dyno test on a 155cc four-stroke engine, the results showed that using a 46 mm size yielded the highest power of 11.03 Hp and produced a torque of 12.39 N.m. Using a 47 mm size resulted in 11.02 Hp and decreased the torque to 12.28 N.m. With a 48 mm size, there was a decrease in power to 11.00 Hp and an increase in torque to 12.7...

This research is a quantitative study using experimental research methods. The 4 stroke petrol engine used is the Yamaha Jupiter MX 135 cc. The data were processed in several stages of analysis using the mean formula, fuel consumption, the percentage formula, and comparing the results of data analysis from each treatment. From the results of data analysis, it was found that the installation of the Turbo Cyclone had an effect on fuel consumption and exhaust emissions from the 4 stroke engine. The best effect is obtained from the installation of the Turbo Cyclone after the carburetor, fuel consumption shows a decrease of up to 8%, exhaust emissions show a decrease in HC levels by 9% and an increase in CO2 levels by 1%. Penelitian ini mambahas pengaruh pemasangan Turbo Cyclone pada mesin bensin 4 Tak terhadap konsumsi bahan bakar dan emisi gas buang....

The use of Bioadditives in fuel aims to improve engine performance and fuel economy. The method used in this research is an experiment with RON 90 Gasoline samples, and a mixture of Citronella Bioadditives with a ratio of S1-1.5%, S2-2.0%, S3-2.5%, S4-3.0%, and S5-3.5%. Engine performance testing using Sportdevice Dyno and impacted engine performance increased by 3.11% on the S4-3.0% type, and maximum torque increase reached 2.03% on the S2-2.0% ratio. The fuel economy test based on the distance traveled with 1000 ml of fuel volume per sample at an average speed of 40-60 km/h was able to achieve a savings of 20.93% on the S5-3.5% sample with a distance of 69.9 Km/l. This is different from RON 90 gasoline without citronella mixture can only be traveled as far as 57.8 km / l. Serai Wangi merupakan ragam bioaditif yang bersifat mudah larut dan menguap ke dalam bahan bakar. Pemakaian Bioaditif dalam...

Lemongrass fragrant oil is one of the types used as bio-additives that are volatile and soluble into fuels. The purpose of using this bio-additive is to improve the performance of the machine, but the resulting emissions must be in permissible regulations. This research was conducted by experimental methods, some of the tested samples consisted of gasoline (Pertalite), then the development was done by adding the element of lemongrass aromatic bio-additive on the fuel with a ratio of 1.5:1000 ml, 2.0:1000 ml, 2.5:1000 ml, 3.0:1000 ml, and 3.5:1000 ml. The sample test was carried out to measure engine performance, exhaust emissions, using Sportdevice Dyno and Emission Tester. Also, fuel consumption testing is carried out to determine the efficiency of fuel consumption. The results of this study the use of a fragrant lemongrass bio-additive can improve the performance of the motorcycl...

combustion chamber volume divided by the volume of the combustion chamber. This study aims to
describe the effects of an increase in the compression ratio of the exhaust emissions of vehicles
motorcycle Honda blade 110 cc. this research uses experimental methods, by doing a comparison
on conditions of emission testing of compression from 9: 1 and 10.2: 1. The research results is an
increase in compression ratio affect the concentration levels of carbon monoxide and hydrocarbon
emissions. The concentration of CO is rising 16.35%, this occurs because of an increase in
compression ratio can increase pressure and temperature on the cylinder, thus causing the
dissociation of molecules of CO2 into CO and O2. While increased levels of concentration of HC
52,74%, this occurs because of an increase in compression ratio can increase the concentration of
hodrokarbon, which is caused by the pressure is greater than the total volume of the engine so that
the combustion process becomes less than perfect.
