Corrosive wear in crosshead diesel engines

نویسنده

چکیده

Existing theories describe corrosive wear in crosshead diesel engines in terms of acid condensation, when the temperature in the combustion space drops below the dew point. Here a theory is proposed which stresses the role of alkaline cylinder lubricants in protecting the metal surface. Calculated liner wear rates as a function of fuel sulphur content, feed rate and alkalinity of the oil, and axial position are in satisfactory agreement with experimental data.

On-line Condition Monitoring and Remote Fault Diagnosis for Marine Diesel Engines Using Tribological Information

Literature review indicates that a large amount of failures are caused by abnormal wear of the diesel engine components. It is therefore essential to monitor the engine condition using the tribological information. Although the wear debris analysis has been proven to be effective for condition monitoring and fault diagnosis (CMFD) of diesel engines, limited work has been done to address the rem...

Research on Diesel Engine Piston Wear Fault Diagnosis Method Based on the Local Wave Time-frequency Analysis

A large number of non-stationary dynamic signals are generated in the working machinery and equipment. Especially, diesel engines often encounter non-stationary transient and time-varying modulation signals, such as the impulse response signals caused by cylinder piston wear. These kinds of signals generated from diesel engine are analyzed by the method of the Local Wave time-frequency proposed...

A critical review on the tribological compatibility of automotive materials in palm biodiesel

Although the compatibility of biodiesel with the key components of automobile engine such as cylinder, pistons, piston rings, connecting rods, bearings, etc. have posed a big challenge to tribologists, they have yet to come up with a solution to reduce tribological degradation of different metals as well as the used fuel. Some efforts have already been given to understand the corrosion and wear...

MODELING AND OPTIMIZING THE CORROSIVE WEAR OF STEEL BALLS IN BALL GRINDING MILL

This paper was aimed to address the modeling and optimization of factors affecting the corrosive wear of low alloy and high carbon chromium steel balls. Response surface methodology, central composite design (CCD) was employed to assess the main and interactive effects of the parameters and also to model and minimize the corrosive wear of the steels. The second-order polynomial regression model...

Is Thermal Barrier Coating for Low Heat Rejection in SI Engines or Diesel Engines?

The diesel / gasoline engine rejects about two thirds of the heat energy of the fuel, one-third to the coolant, and one third to the exhaust, leaving only about one-third as useful power output. Theoretically if the heat rejected could be reduced, then the thermal efficiency would be improved, at least up to the limit set by the second law of thermodynamics. Low Heat Rejection (LHR) engines aim...
