[b]Water content in diesel oil[/b]
(OP)
Hi,
I have several questions about this issue:
1. In principle, what is the effect of higher than normal water content in diesel oil on vehicle diesel engine.
2. Considering the following values - app. 500 - 800 ppm compared to 200 ppm max. (according a EN-590 European standard)can this values cause any harm to the engine.
3. Is it possible that such contaminated fuel can alter the engine timing system setup and thus change engine timing.
4. Where can I find articles about this issue.
Regards,
Ariky

RE: [b]Water content in diesel oil[/b]
Excess water in diesel fuel can cause scoring of the injectors and a poor fuel spray pattern into the cylinders. This in trun can cause incomplete combusiton, and black smoke. Water destroys the lubricity of the diesel fuel (which is marginal to start)
The fuel shold be delivered with virtually no water. Diesel engines usually have water filters before the fuel enters the engine fuel system. Excess water will cause these filters to require more frequent cleaning.
Damage caused by excess water will not alter injection timing, but will cause fuel to bypass the plunger and lower the injection pressure which results in a poor spray pattern. You can see this on an injector test bench.
Hope this helps

Dave
