A Study of Oil Consumption on a Diesel Engine with Independently Lubricated Turbocharger

For combined-cycle power plant performance analysis, a ship power plant mathematical model is developed, including diesel engine, controllable pitch propeller, exhaust gas boiler, turbine generator and shaft generator models. The simulation performance characteristic curves of diesel engine under various loads are given. Comparison of simulation results and experimental data shows the model can well predict the performance of diesel engine in various operating conditions. The specific fuel oil consumption contours of combined-cycle power plant and the relations between engine operating conditions and steam cycle parameters are given. The influence of diesel engine operating conditions to the overall performance of combined-cycle power plant is discussed.

Di Diesel Engine

Nowadays, the increasing oil consumption throughout the world induces crucial economical, security, and environmental problems. As a result, intensive researches are undertaken to find appropriate substitution to fossil fuels. In view of the large amount of eucalyptus trees present in arid areas, we focus in this study on the investigation of using eucalyptus biodiesel as fuel in diesel engine. Eucalyptus oil is converted by transesterification into biodiesel. Eucalyptus biodiesel characterization shows that the physicochemical properties are comparable to those of diesel fuel. In the second phase, a single cylinder air-cooled, DI diesel engine was used to test neat eucalyptus biodiesel and its blends with diesel fuel in various ratios (75, 50, and 25 by v%) at several engine loads. The engine combustion parameters such as peak pressure, rate of pressure rise, and heat release rate are determined. Performances and exhaust emissions are also evaluated at all operating conditions. Results show that neat eucalyptus biodiesel and its blends present significant improvements of carbon monoxide, unburned hydrocarbon, and particulates emissions especially at high loads with equivalent performances to those of diesel fuel. However, the NOx emissions are slightly increased when the biodiesel content is increased in the blend.

Emulsified Fuel

In order to achieve the application of emulsified fuel oil on the marine,our discussion group developed a set of heavy fuel oil intelligent online emulsifying equipment tested on G6300ZC18B diesel of the ship Ningda "6". And the experimental result shows that, when water mixing ratio ranged from 16% to 24%, emulsification reached good level to apply as marine fuel. When burning emulsified fuel oil, the explosive pressure of diesel engine fluctuated in the range of 1-2Mpa, the exhaust temperature decreased 12°Cand the outlet temperature of cooling water declined slightly, but all the parameters above are in the normal range. The oil consumption decreased by 9.7% and the emission of NOX ,carbon smoke ,and CO reduced by 19.6%,20%,35% respectively.
