==Tribology Laboratory - University of Pretoria==

[[File:Tribpic.jpg|300px|right]]

The tribology group is headed by Professor Philip de Vaal and was started in 1987 with support from ESKOM, Anglo-American and ISCOR. The activities in the lab focus on lubricant performance evaluation, which includes analysis of greases, oils and diesels. More recent industrial problems with diesel quality in South Africa motivated research in the field of diesel lubricity and biodiesel, sponsored by Sasol.

The Tribology Lab not only functions as a academic research lab, but also as an evaluation lab for industry. Several companies use the Tribology Lab for failure analysis and quality control.

The first section gives information regarding the '''[[Tribology#Equipment|equipment]]''' used in the Tribology Lab. The user manuals, test procedures and ASTM/ISO/DIN/SABS standards for each piece of equipment is included in the respective pages. Documentation of past and present projects can also be found there.

The second section includes all the work and some of the literature regarding '''[[hip tribology]]''', and the third section has all the past |test results done for partners in industry. A password is required to access this page.

Section five gives access to all the ASTM/ISO/DIN/CEC/SABS '''[[Standards and Procedures|standards and procedures]]''' that are not included in the equipment section. You will also need a password to access this page.

The last section contains all the project files and documents of students who worked on the [[Diesel and Biodiesel Lubricity|diesel lubricity and biodiesel]] project.

You will find this page most useful when starting out with a new project or when you just have a problem in the lab. The aim of this site is also to log everything that happens in the lab to help create continuity between students responsible for the well-being of the lab.

Diesel and Biodiesel Lubricity

2010-12-13T13:20:59Z

Gerhard Marais: /* 2010 */

[[File:Einspritzduese.jpg|500px|right]]
In modern diesel engines, the fuel also fulfils the role of lubricant in the fuel distribution system. Increasingly stringent environmental legislation forces engine manufacturers to decrease the combustion temperature to limit the amount of NOx’s and SOx’s that enter the environment. To achieve this better control of injection -and combustion processes are necessary, seeing that incomplete combustion at lower temperatures will cause soot and unburnt hydrocarbons to enter the atmosphere. The introduction of common rail diesel injection technology ensured that good control was possible, but at this stage the injection pressure is about 15 times higher than it was with conventional plunger injection. The clearances between the injection equipment have also been decreased to ensure that the pressure is not lost through the system. This has placed new demands on the lubrication properties of diesel.

South African environmental legislation limits the amount of sulphur in diesel to 500ppm. The sulphur is removed through a process of hydrotreating the crude oil fractions that are used to blend diesel. The problem is that this process also removes other naturally occurring lubricity enhancing components with the sulphur. As a result of this lubricity additives need to be added to the fuel. Biodiesel (fatty acid methyl esters) have very good lubricity, but have several other limitations.

The tribology group is headed by Professor Philip de Vaal and was started in 1987 with support from ESKOM, Anglo-American and ISCOR. The activities in the lab focus on lubricant performance evaluation, which includes analysis of greases, oils and diesels. More recent industrial problems with diesel quality in South Africa motivated research in the field of diesel lubricity and biodiesel, sponsored by Sasol.

The Tribology Lab not only functions as a academic research lab, but also as an evaluation lab for industry. Several companies use the Tribology Lab for failure analysis and quality control.

The first section gives information regarding the '''[[Tribology#Equipment|equipment]]''' used in the Tribology Lab. The user manuals, test procedures and ASTM/ISO/DIN/SABS standards for each piece of equipment is included in the respective pages. Documentation of past and present projects can also be found there.

The second section includes all the work and some of the literature regarding '''[[hip tribology]]''', and the third section has all the past |test results done for partners in industry. A password is required to access this page.

Section five gives access to all the ASTM/ISO/DIN/CEC/SABS '''[[Standards and Procedures|standards and procedures]]''' that are not included in the equipment section. You will also need a password to access this page.

The last section contains all the project files and documents of students who worked on the [[Diesel and Biodiesel Lubricity|diesel lubricity and biodiesel]] project.

You will find this page most useful when starting out with a new project or when you just have a problem in the lab. The aim of this site is also to log everything that happens in the lab to help create continuity between students responsible for the well-being of the lab.
