A Neo Emission Reduction Approach for Minimizing Atmospheric Air Pollutants Using Ternary Fuel with Pentanol and Seaweed Anti-Oxidant in Multi-Cylinder Diesel Engine

Emission Reduction Strategies for Small Single Cylinder Diesel Engine Using Valve Timing and Swirl Ratio

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

Real-time Nonlinear Individual Cylinder Air Fuel Ratio Observer on a Diesel Engine Test Bench

We propose an estimator of the individual cylinder air fuel ratios in a turbocharged Diesel Engine using as only sensor the single air fuel ratio sensor placed downstream the turbine. The observer consists of a nonlinear filter designed on a physics-based time-varying model for the engine dynamics. Convergence is proven, using a Lyapounov function. Performance is studied through simulations and...

Nitrous Oxide Emissions on Single Cylinder Diesel Engine Using Variable of Fuel Sulfur and Emulsion Fuel

The aim of this work is to investigate the influence of NO/SO2 on the emissions of N2O from diesel engine. A direct-injection diesel engine (model NF-19SK YANMAR) one cylinder was employed to test the emission. This engine works on fourstroke cycle and was operated at 2200 rpm by 25, 50, and 75% engine load. The experiment by three level sulfur content of fuel by adding DBDS into MDO and experi...

Investigation of performance and exhaust emission of diesel engine in different ratios of lambda coefficient using diesel-ethanol fuel blends

In recent decades, rising greenhouse gas emissions have become a major challenge and concern. Environmental pollution is one of the greatest human challenges of the 21st century. Improving the performance of internal combustion engines and reducing the amount of pollutant emissions has always been a concern for researchers. The use of alternative fuels and the control and adjustment of the lamb...
