Motor bakar merupakan salah satu mesin kalor yang banyak digunakan sebagai alat penggerak mula. Kemajuan teknologi menjadikan tingkat kebutuhan penggunaan motor bakar semakin meningkat, tetapi berbanding terbalik dengan adanya persediaan bahan bakar daripada motor bakar tersebut.            Sistem injeksi dirancang untuk mendapatkan nilai yang mendekati ideal pada kondisi mesin. Bahan bakar diinjeksikan dan dalam jumlah yang sudah tepat, sesuai dengan jumlah udara yang masuk ke dalam intake manifold.Semakin lama waktu pemakain suatu mesin, maka akan semakin menurun kemampuan mesin tersebut, dan akan semakin banyak bahan bakar yang hatus dikomsumsi untuk menghasilkan daya yang besar untuk mengatasi diperlukan Inovasi  teknologi  menggunakan  SFI (Sequential multi port Fuel Injection) merujuk kepada gambaran  performance  dari kinerja  yang diperhatikan kebutuhan penggunaan mesin tersebut, diperlukan perawatan secara berkala dan untuk menghemat pengkomsumsian bahan bakar. SFI(Sequential multi port Fuel Injection) Engine menyediakan kira-kira 10% tenaga putaran yang lebih besar setiap kali melakukan percepatan.Kata kunci : Motor Bakar, Fuel Injection, Performance

The Impact

Abstract. Gasoline vehicles significantly contribute to urban particulate matter (PM) pollution. Gasoline direct injection (GDI) engines, known for their higher fuel efficiency than that of port fuel injection (PFI) engines, have been increasingly employed in new gasoline vehicles. However, the impact of this trend on air quality is still poorly understood. Here, we investigated both primary emissions and secondary organic aerosol (SOA) formation from a GDI and a PFI vehicle under an urban-like driving condition, using combined approaches involving chassis dynamometer measurements and an environmental chamber simulation. The PFI vehicle emits slightly more volatile organic compounds, e.g., benzene and toluene, whereas the GDI vehicle emits more particulate components, e.g., total PM, elemental carbon, primary organic aerosols and polycyclic aromatic hydrocarbons. Strikingly, we found a much higher SOA production (by a factor of approximately 2.7) from the exhaust of the GDI vehicle than that of the PFI vehicle under the same conditions. More importantly, the higher SOA production found in the GDI vehicle exhaust occurs concurrently with lower concentrations of traditional SOA precursors, e.g., benzene and toluene, indicating a greater contribution of intermediate volatility organic compounds and semi-volatile organic compounds in the GDI vehicle exhaust to the SOA formation. Our results highlight the considerable potential contribution of GDI vehicles to urban air pollution in the future.
