Signs of a Failing EVAP canister

Image
The canister purge valve, also commonly referred to as the purge valve, is an important component of your Evaporative Emission Control (EVAP) system. This system restricts the fuel vapours created in your fuel tank from escaping into the atmosphere by trapping them in a charcoal canister. When your engine begins to run at regular speed, the EVAP system slowly allows these vapours to be released into your engine, which burn like regular fuel. The flow of these vapours is controlled by your canister purge valve, which regulates when and how much of these vapours enter your engine. The canister purge valve is electrically operated, and is also referred to commonly as a solenoid. The most common purge valve issues are when the purge valve is stuck open or closed, or does not open at the proper time. The symptoms are listed below that may indicate your canister purge valve is not functioning properly. 1. Check Engine Light Is On The first sign of trouble for your canister purge valve is the

Why your car(s) smoke black?

If your car(s) have this  problem of black smoke and you buy fuel more than usual, then there is something wrong with it. Incomplete combustion, in other words, fuel delivered to the combustion chamber, being more than oxygen supply and not burnt completely will cause black smoke of an  engine, prompting check engine light to illuminate and a rotten egg smell is also perceived. This error is caused by a lambda (oxygen) sensor. Although many variables may contribute, the discussion is on lambda sensor. What is the work of a lambda sensor? Lambda sensor serves as the nose of a PCM (power control Module), it tells the system's computer how much oxygen is available, by sniffing, then the pcm will now determine the air/fuel ratio to use for a stoichiometric combustion.   If the sensor sniffs more oxygen, it will send signal to pcm  and equivalent fuel will be supplied to ensure a complete burning. What does complete burning mean in an engine? A complete burning or combu
