No, diesel engines don't have ignition coil as they work on compression ignition and not on spark ignition as in diesel engines. Glow plugs used in diesel are like small electric heaters which use the mechanism of heating due to resistance during electrification.
Clarithromycin is another antibiotic treatment for walking pneumonia. It is more powerful than even erythromycin as it is also used to help treat HIV/AIDS patients. It works by interfering with the protein synthesis of bacteria, which prevents them from growing further. It is given in the form of tablets or a gel.
Answers from Eric J. Olson, M.D. Walking pneumonia is an informal term for pneumonia that isn't severe enough to require bed rest or hospitalization. You may feel like you have a cold. The symptoms are generally so mild that you don't feel you need to stay home from work or school, so you are out walking around.
