Several studies have been conducted on alternatives to fossil fuels in internal combustion engines. In this work, we present an analysis of the optimization a spark ignition engine (SIE), which operates with mix gasoline and hydrogen. Thus, study tries enrich literature about effect using hydrogen SIEs taking into account their performance environmental issues. The experiments were considering ...

In recent decades, the automotive industry has had a constant evolution with consequent enhancement of products quality. industrial applications, quality may be defined as conformance to product specifications and repeatability manufacturing process. Moreover, in modern era Industry 4.0, research on technological innovation made real-time control process possible. Moving from above context, met...

Cationic dye - basic red 2 (BR2) was removed from aqueous solutions by sulfuric acid activated waste Gossypium hirsutum seeds (WGSAB). The main and interactive effects of five process variables such as, adsorbent dose (1.25 – 5 g/L), initial dye concentration (100–300 mg/L), contact time (1–3 h),  pH (2 – 12) and temperature (20 – 400C) were investigated via  response su...
