The ongoing monitoring of marine diesel engines helps to detect the deviations its parameters early and prevent major failures. But experimental diagnostics data are generally limited, so frequently, it isn’t possible get all necessary information make a clear decision. mathematical simulation could be used clarify provide deeper understanding engine conditions. In this paper, MAN 6L80MCE “Fath...

The development and implementation of a diesel engine combustion system simulation model is described. The model is a crank angle based combustion model, which uses the conditions in the intake and exhaust manifolds together with the fuel injection signal from the engine control unit to estimate the in-cylinder pressure throughout a complete combustion cycle. The model is implemented in Matlab....

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...

As a result of declining oil reserves in the world, the rise in fossil fuel prices and growing interest in the environment, there is considerable demand for alternative fuels. Biodiesel is recognized like the "green fuel" and has several advantages compared to diesel. It is safe, renewable, nontoxic, and biodegradable (98% biodegradable in a few weeks). Contains less sulfur compounds, and has a...

Gasand particle-phase tailpipe emissions from latemodel medium duty diesel trucks are quantified using a twostage dilution source sampling system. The diesel trucks are driven through the hot-start Federal Test Procedure (FTP) urban driving cycle on a transient chassis dynamometer. Emission rates of 52 gas-phase volatile hydrocarbons, 67 semivolatile and 28 particle-phase organic compounds, and...
