Any engine, whether gasoline or diesel, requires compression to operate. The process of compression confines and presses a mixture of air and fuel into a small volume within the area of the engine’s cylinder. This process presses together all the molecules under very high pressure. Since the gasoline engine has a spark plug, only moderate compression is enough, requiring about 140-160 pounds per square inch (PSI).
A Compression test is a good way to measure the condition of the rings, cylinders, and valves. If your engine is running rough or is lacking power consider doing a compression test. It is important […]
You may have heard the term “valve job” because older engines frequently needed their valves reconditioned. You rarely hear about valve problems in today’s engines because modern OHC engines have fewer components to wear out […]
An engine compression test is the most practical way to learn about the mechanical condition of your engine. Doing a engine compression test will help you locate potential internal problems affecting engine performance. Running rough […]
What is misfiring and what are the causes of misfiring? In order for a cylinder to fire properly, it needs 4 things all working together: Proper Fuel/Air Mixture Good Compression Proper Timing Correct Spark Common […]
