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.
Erythromycin. Erythromycin is a very common antibiotic treatment for walking pneumonia.

There is no simple answer. Pneumonia can be caused by chemicals, viruses and bacteria, by not breathing properly when bedridden, by immune system problems and other causes. The first thing you need to know is the cause of the person's pneumonia. When you know the cause, you can look at treatments. If a normally healthy young person has a pneumonia caused by a bacteria or germ, and if that germ is easily destroyed by ordinary antibiotics, recovery will take a few weeks.
