Pleural effusion may be caused by cancer, cancer treatment, or other conditions. A pleural effusion may be malignant (caused by cancer) or nonmalignant (caused by a condition that is not cancer). Malignant pleural effusion is a common problem for patients who have certain cancers. Lung cancer, breast cancer, lymphoma, and leukemia cause most malignant effusions.
Supercharged Engine. A (also known as a blower) is an air compressor used to force air into the combustion chamber(s) of an internal combustion engine at pressures higher than would otherwise be the case. Any device which does this is a .
If the air compression is driven by the engine's crankshaft the turbo device is called a supercharger. There are many designs of turbos and superchargers, though they all operate on the same simple principle.ackground. Because proper combustion in an engine requires a precise air-to-fuel ratio of 14:1, pumping more gas into an engine to increase its power output would be useless without a much larger supply of air to the combustion chambers. An engine simply requires much more air than fuel.
