How to Correctly Maintain Your Volvo Engine

The classic rule engine supports testing and simulation in both Enterprise and Business consoles, but the decision engine works in only decision services in the Business console.

You can run tests and simulations on decision services that use either the classic rule engine or the decision engine. A rule engine is associated with a decision service in Rule Designer, and all the decision operations in a decision service must run the same rule engine. The Business console checks decision services to determine whether they are correctly configured.

In Rule Designer, you can reconfigure a decision service to run on a different rule engine. If the decision service is already in Decision Center, you must synchronize the decision service to implement the change in the center.

In the Business console, you must select a server that has the runtime service application that supports the decision Volvo diesel engine that is used by your decision service.

Simulation and test suite artifacts have a Server property that you can set to point to the appropriate server. When you create a new simulation or test suite, the list of available servers is filtered. You see only the servers that are compatible with the rule engine that is used by the decision service.

If you change rule engine, the Business console automatically searches for a compatible server. If a specified server does not match the available servers, the console notifies you that a server cannot be found. You can edit the Server property of a test suite at any time.

The following table lists the rule engines by validation operation and Decision Center console. The table also shows the supported scenario files, and the Scenario Service Provider (SSP) and Decision Runner runtime service applications, which run the tests and simulations in Rule Execution Server.

Most owners understand that frequent oil changes are a must. The typical interval is every 100 hours, but this varies from as few as 50 to as many as 200 hours (small engines like my 1.6 Liter Yanmar take only a small quantity of oil, and need more frequent oil changes, in this case, every 50 hours).

Delo 400 Oil

Oil in a diesel works hard—much harder than in a gas engine—because the engine works at a high temperature and under extreme pressure. Diesel oil also contains traces of sulfur, especially in countries other than the U.S., which gets transformed into destructive sulfuric acid inside your engine.

Also, many boats, especially small cruising sailboats, operate their engines infrequently and for short periods of time, when pulling into or out of their slip. They may also run the engine for long time periods at low RPM, for charging battery banks or freezing the refrigerator’s holding plate. Both of these practices are rough on your engine. The engine doesn’t warm up to operating temperature, causing moisture to condense inside, creating sulfuric acid and also a buildup of carbon.

If this carbon remains inside your engine, the lubricating ability of the oil is substantially reduced. Plus, this buildup of soot coats valves and valve stems, which reduces the compression of your engine. All the experts agree that you should avoid running the engine for short durations and/or at low loads. If you do a lot of this type of motoring, you’re going to need more frequent oil changes with top-quality oil and good filters.

Decoding Engine Oil

Before purchasing new oil, remember that oil that is great for a gasoline inboard is not always right for a diesel. Your owner’s manual should state the API (American Petroleum Institute) and SAE (Society of Automotive Engineers) ratings that denote the correct oil for your engine. These ratings should appear on the container of the oil you buy. API ratings that begin with the letter C (for Compression ignition) are formulated for use in diesel engines. Ratings that begin with the letter S (for Spark ignition) are formulated for gasoline engines.

The letters C or S are followed by a second letter that indicates the complexity of the additive package. These letters ascend up the alphabet. Oils containing more complex additive packages can, in general, be used with prior formulations. For example, if you own a diesel and the manual says, “use CD”, oil rated CE will be fine. Many oils are now formulated for use with both gasoline and diesel engines. For example, Chevron’s 30 and 40 weight DELO 400 is currently rated CJ-4 and SM.
