current approaches to the analysis of internal combustion engines are no longer merely based on the first law of thermodynamics and are conducted from the second law either. the evaluation of processes by the first law cannot provide a sophisticated insight into the issue. so, due to the necessity of having a detailed perspective of the losses in different thermodynamic processes, a useful meth...

The production of torque and pollutants of Variable Valve Actuation equipped internal combustion engines found in the automotive industry (both Diesel and gasoline engines) is studied. Variable Valve Actuation (VVA) is a technology which has been introduced to optimize engine efficiency at steady-states covering a wide range of operating conditions. In more details, the outcome of the internal ...

Author is pointing at the possibility of the utilisation of simulated computations for the research and development of the Car TDI diesel engines. Modern technical potential of them is discussed in the opening part of the paper with emphasis on the Latest Fuel Injection Technology. In this part of the paper one can find a short characteristics of the Engine, Exhaust Gas Recirculation, Selective...

The depletion of world petroleum reserves and the increased environmental concerns have stimulated the search for alternative sources for petroleum-based fuel, including diesel fuels. Because of the closer properties, biodiesel fuel from non-edible oil is considered as the best candidate for diesel fuel substitute in diesel engines. With increasing demand on the use of fossil fuels, stronger th...

Hydrogen fuel is the cleanest fuel available. This fuel can be used as an additive in the diesel engine. Diesel engines have the advantages of strong power, high thermal efficiency and low fuel costs. There have been extensive studies on the use of hydrogen fuel in diesel engines in recent years. However, the simultaneous effect of using gaseous hydrogen fuel and changing injection strategy nee...

Natural gas-diesel dual fuel combustion is a beneficial strategy for achieving high efficient and low emissions operation in compression ignition engines, especially in genset application heavy duty diesel engine at rated power. This study aims to investigate a dual fuel engine performance and emissions using premixed natural gas and early direct injection of diesel fuel. Due to the different r...
