Numerical and Experimental Analysis of the Potential Fuel Savings and Reduction in CO Emissions by Implementing Cylinder Bore Coating Materials Applied to Diesel Engines

Currently, internal combustion engines contribute to the problem of global warming due their need use products derived from fossil resources. To mitigate above problem, this study proposes coatings on cylinder bore in order reduce fuel consumption and polluting emissions. Therefore, present a numerical model is developed which tribological behavior, heat fluxes, leakage gases chamber are considered evaluate influence coating. Nickel nanocomposite (NNC) diamond-like carbon (DLC) study. The results demonstrate that NNC coating produces 32% reduction total friction force compression ring. estimated maximum temperatures for lubricating oil were 214, 202, 194 °C DLC, steel, materials. Increasing temperature DLC can cause performance lubricant. estimates made show implementation allows 5.28 ton 39.30 kg CO emissions, based fleet diesel forecast year 2025 (corresponding one hundred eighty million engines) test time 1800 s. proposed future analyses be carried out other types materials used as coatings. Additionally, expanded adapted consider systems involve processes engine.
