Application of Miller Cycle and Net-Zero Fuel(s) to Diesel Engine: Effect on the Performance and NOx Emissions of a Single-Cylinder Engine

Diesel engines play a very significant role in the automotive industry, but total emissions of diesel are more than 1.8 times that petrol engines. It is therefore important for to control emissions. Theoretically, Miller cycle can be used achieve NOx reductions by changing effective compression ratio, while it has become increasingly popular recent years with increasing maturity current turbocharging technology. Based on Ricardo WAVE software, this paper analyses and engine performance modelling simulating their operation under different loads two types cycles (EIVC LIVC) at degrees. Simulation operating allows comprehensive study effects engine, specific analysis context actual environment. The result both versions most reducing 10% load, showing maximum reduction 21% EIVC 37% LIVC. However, as decreases power, further investigates application turbocharger systems cycle, results 32% increase brake power load −25% degree. Both ethanol-fueled diesel-cycle were also analyzed, was observed, well hydrogen
