Injection Control Valve (ICV) leaks, engine start issues, and high air consumption.
Hello!
Heavy fuel is "heavy" in every sense of the word. Even Soviet literature described the various problems that arise when running an engine on fuel oil, compared to running it on distillate.
As the years went by, these problems worsened as the oil refining process became more sophisticated.
Here's an example of a high-tech, electronically controlled internal combustion engine that suffers from poor fuel quality just like its predecessors.
