“…Untuk meningkatkan efisiensi dan performa mesin serta mereduksi emisi gas buang dari motor bakar bisa dilakukan dengan berbagai macam cara, salah satunya adalah dengan sistem injeksi air [3]. Pada sistem injeksi air, proses pemasukan air bisa dilakukan melalui saluran masuk atau dikenal dengan istilah Port Water Injection (PWI), bisa juga dimasukkan langsung ke dalam ruang bakar yang disebut Direct water Injection (DWI) [4]. Injeksi air pada saluran masuk akan mendinginkan campuran udara masuk sehingga membuat udara yang masuk menjadi lebih padat sehingga menghasilkan tenaga yang lebih besar.…”

Penelitian ini bertujuan untuk membandingkan performa motor otto dengan bahan bakar pertalite dengan dan tanpa injeksi air. Pengujian dilakukan pada sepeda motor bermesin empat langkah silinder tunggal berkapasitas 103 cc. Mesin uji dimodifikasi dengan sistem Port Water Injection (PWI) yang dikendalikan secara elektronik menggunakan Arduino Uno. Injektor bahan bakar digunakan untuk menyemprotkan air bertekanan tinggi yang dipasok oleh pompa listrik. Air disuntikkan ke intake manifold ketika langkah intake terjadi. Dinamometer inersia digunakan untuk mengukur torsi dan daya mesin yang dihasilkan. Hasil penelitian menunjukkan bahwa penambahan sistem injeksi air dapat meningkatkan torsi dan tenaga mesin. Rata-rata peningkatan tenaga dan torsi masing-masing adalah 9,37% dan 8,45%. Kata kunci : Performa mesin, injeksi air, Arduino Uno

This paper presents an experimental study investigating the effects of water-in-gasoline emulsion (WiGE) on the performance and emissions of a turbocharged PFI spark-ignition engine. The emulsions were produced through a micro-channels emulsifier, potentially capable to work inline, without addition of surfactants. Measurements were performed at a 3000 rpm speed and net Indicated Mean Effective Pressure (IMEP) of 16 bar: the engine point representative of commercial ECU map was chosen as reference. In this condition, the engine, fueled with gasoline, runs overfueled (λ = 0.9) to preserve the integrity of the turbocharger from excessive temperature, and the spark timing corresponds to the knock limit. Starting from the reference point, two different water contents in emulsion were tested, 10% and 20% by volume, respectively. For each selected emulsion, at λ = 0.9, the spark timing was advanced from the reference point value to the new knock limit, controlling the IMEP at a constant level. Further, the cooling effect of water evaporation in WiGE allowed it to work at stoichiometric condition, with evident benefits on the fuel economy. Main outcomes highlight fuel consumption improvements of about 7% under stoichiometric mixture and optimized spark timing, while avoiding an excessive increase in turbine thermal stress. Emulsions induce a slight worsening in the HC emissions, arising from the relative impact on combustion development. On the other hand, at stoichiometric condition, HC and CO emissions drop with a corresponding increase in NO.
