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.
Walking pneumonia is generally treated with antibiotics. Mild infections are often not treated because they tend to clear on their own. With treatment, most people begin to feel better within a few days. Many over-the-counter medicines used for colds and flus may not help with complete relief of symptoms of walking pneumonia. It's important to talk with your doctor about any medicines you are taking or planning to take.
Getting enough calories to sustain the energy needs and gain weight is of prime importance in pneumonia diet treatment. Eat small meals frequently, at least five to six times rather than three large meals. Add high calorie items such as milkshakes, custards, pudding, butter, eggs, and cottage cheese in your meals. Protein is necessary to rebuild the damaged tissue of the lungs in pneumonia. Choose protein rich foods such as fish, chicken soup, eggs, lean meat, soybeans, seeds and nuts, flax seeds, tofu etc. Eat moderate amount of fat as it also helps to increase the calories.
