Engine Runs Rough
Rough Running Engine
Let us not forget that the engine runs rough condition can be caused by basic car problems. Many times professional and do it yourself auto mechanics start searching for answers in the vehicles high tech areas.
In many cases, the car problem is located in the most basic principles of engine operation.
Not all engine performance problems are directly related to on-board computers, throttle position sensors, fuel injectors or other fancy electronic systems.
This is the reason that all types of mechanics will still need to understand basic engine operation, as well as time tested engine testing procedures.
These basic tests are an important part of modern day engine troubleshooting and this will not change for some time. Well at least not until the electric vehicle is the only car on the roadways. Read more
Rough Running Engines
Rough running engines are often caused by basic system problems. Often Diy car mechanics start searching for answers in the automobiles high tech areas.
In many cases, the car problem is located in the most basic principles of engine operation.
Not all engine performance problems are directly related to electronic control systems, oxygen sensors, fuel injectors or other cutting edge electronics.
Therefore a do it yourself mechanic still needs to understand engine testing procedures. These basic tests are an important part of modern engine troubleshooting.
To follow I will discuss two common engine testing procedures that should be considered when trying to diagnose lack of power or rough running engines. Many people in the car repair industry would consider these next tests a car mechanics best friend.
Lack of power | Rough running engines
Internal combustion engines rely on the compression of the air fuel mixture to maximize the power produced.
The upward movement of the piston on the compression stroke will compress the air fuel mixture within this sealed chamber making it easier to ignite and also burn completely.
An engine with low compression will not run correctly, cannot be tuned properly and will have lack of power. A compression tester gauge is used to check the cylinders ability to seal against high pressures.
This is an easy to use inexpensive tool that comes with complete instructions on how to use it. Before conducting a compression test, it is recommended to Read more
