The main objective of this research is to study the effects of n-butanol and ethanol addition to the biodiesel-diesel fuel mixture on the performance and emission characteristics of a CI engine. The experimental tests were performed on a diesel engine. The RSM (Response Surface Methodology) method was used to develop mathematical models based on experimental data. According to the results, the ...

The paper shows a test results of single cylinder, direct injected, self ignited dual fuel engine. One has analysed a combustion parameters calculated on base of recorded indicator diagrams. The comparison included: the ignition delay period, the cylinder pressure, the rate of pressure rise, the average medium temperature, the heat release rate, the total combustion time and the indicated effic...

It is very well known that the efficiency of an SI engine is limited by knock occurrence. As a compromise between knocking combustion avoidance and an accepted level of efficiency, an engine is typically operated at very close to the knocking boundary. However, the position of an engine knocking boundary is shifted if the fuel composition changes. The description of this abnormal combustion is ...

High pressure amount of fuel in new generation diesel engines’ injector equipped with multiple and small nozzle holes has created significant improvement in the outgoing spray behavior and engine performance. On the other hand, poor fuel quality and injector nozzle embedded in high temperature combustion chamber form fundamental deposits on the nozzle leading to fuel spray inappropriate behavio...

Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...

An experimental study is performed to investigate the fuel impingement on cylinder walls and piston top inside a directinjection spark-ignition engine with optical access to the cylinder. Three different fuels, namely, E85, E50 and gasoline are used in this work. E85 represents a blend of 85 percent ethanol and 15 percent gasoline by volume. Experiments are performed at different load condition...

In this study performance characteristics of ammonia engines using direct injection strategies are investigated. Ammonia is a carbon-free fuel, and thus its combustion does not produce carbon dioxide, a critical greenhouse gas. Ammonia can be produced by using renewable energy sources (e.g., wind and solar) and used as an energy carrier. Recent research also has shown that the efficiency of sol...
