INTERNAL COMBUSTION ENGINE- TROUBLES
INTRODUCTION
The internal combustion (I C) engines are most common since these are an integral part of every vehicle. These are also very common to various machines and equipment’s. There are numerous troubles associated with it. Many troubles can be overcome by learning properly the starting and operating the engine as prescribed procedure in the manufacturer catalog. Experience is the best teacher to sense the trouble and take appropriate action to tackle the trouble.
The procedures for trouble shooting of internal-combustion engines are somewhat similar for both diesel and gasoline engines.

Successful troubleshooter is one who has the ability to recognize the symptoms for a certain trouble and is also able to locate the trouble. Then, one must be able to decide quickly what corrective action is to be taken. Various troubles are mechanical, electrical, chemical,, noise and air pollution nature.
