Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh perubahan bukaan katup intake dan penambahan udara bertekanan terhadap performa dan kadar emisi NOx pada mesin diesel 1 silinder berbahan bakar biodiesel. Uji eksperimen dilakukan dengan menggunakan bahan bakar B35 Pertamina dan B100 dari kelapa sawit,dengan kombinasi modifikasi camshaft dan penambahan udara bertekanan. Hasil penelitian menunjukkan bahwa perubahan bukaan katup intake berpengaruh signifikan terhadap efisiensi pembakaran, yang menghasilkan peningkatan daya mesin dan konsumsi bahan bakar yang lebih rendah. Penambahan udara bertekanan juga terbukti efektif dalam mengurangi emisi NOx dengan meningkatkan kualitas pembakaran. Pada putaran mesin yang berbeda, variasi beban palsu menunjukkan bahwa modifikasi camshaft dan penambahan udara bertekanan mampu meningkatkan performa mesin secara keseluruhan, dengan nilai Specific Fuel Oil Consumption (SFOC) yang lebih rendah. Emisi NOx dari biodiesel tanpa modifikasi cenderung lebih tinggi dibandingkan dengan penggunaan siklus Miller, namun modifikasi camshaft dan penambahan udara bertekanan secara signifikan mengurangi kadar NOx dalam emisi gas buang. Studi ini menyimpulkan bahwa melalui modifikasi teknis yang tepat, yaitu perubahan bukaan katup intake dan penambahan udara bertekanan, performa mesin diesel dapat dioptimalkan dan emisi NOx dapat dikurangi. Penelitian ini memberikan kontribusi penting dalam pengembangan teknologi mesin diesel yang lebih ramah lingkungan dan efisien, serta memberikan dasar bagi penelitian lebih lanjut dalam optimisasi mesin diesel berbahan bakar biodiesel

This study aims to analyze the effect of changes in intake valve opening and the addition of compressed air on the performance and NOx emission levels of a 1-cylinder diesel engine fueled by biodiesel. Experimental tests were conducted using B35 Pertamina fuel and B100 from palm oil, with a combination of camshaft modification and the addition of compressed air. The results showed that changes in the intake valve opening had a significant effect on combustion efficiency, resulting in increased engine power and lower fuel consumption. The addition of compressed air was also proven effective in reducing NOx emissions by improving combustion quality. At different engine speeds, variations in false loads showed that camshaft modification and the addition of compressed air were able to improve overall engine performance, with lower Specific Fuel Oil Consumption (SFOC) values. NOx emissions from unmodified biodiesel tended to be higher than those using the Miller cycle, but camshaft modification and the addition of compressed air significantly reduced NOx levels in exhaust emissions. This study concluded that through appropriate technical modifications, namely changes in the intake valve opening and the addition of compressed air, diesel engine performance can be optimized and NOx emissions can be reduced. This research makes an important contribution to the development of more environmentally friendly and efficient diesel engine technology, and provides a basis for further research in the optimization of biodiesel-fueled diesel engines
