Although you may not be familiar with the problem of low engine compression, if it happens to you, you will learn very quickly how difficult it can be. What is low engine compression, why does it happen and what can you do about it?
Put really simply: an internal combustion engine, such as the one in your car, works entirely on the principle of compression. Fuel injectors mix gasoline and air and spray this combination into a combustion chamber, where it is ignited, creating combustion which compresses in the cylinders of the engine to power the car and make it move. It’s easy to see how low compression could create a problem for a motor vehicle.
If you have car engine compression problems, your car will either misfire when you start the engine, perform poorly or, if you have low or no compression in all cylinders, won’t start at all. You can’t drive your car for long, if at all, with low compression. You need to address the problem immediately, but first, you must understand the causes of low engine compression.
