A charcoal canister captures potentially harmful emissions from a car’s engine and prevents them from being released into the atmosphere. A charcoal canister, also known as a vapor canister, is the part of a car’s evaporation control system that is designed to prevent the release of volatile organic compounds that escape from a car’s fuel system and engine.Know More
Charcoal pellets in the canister absorb the harmful fumes emanating from the car’s fuel system and store them until the engine burns them when it is running.
The canister is normally black and is placed in one of the far corners of the engine compartment. However, some car manufacturers mount the canister closer to the fuel tank so as to maximize efficiency.
Evaporation control systems in cars were introduced in the 1960’s and their initial purpose was to absorb crankcase fumes and prevent them from venting out into the atmosphere via road draft tubes that were in use at the time. The emitted vapors were visible and were thought to be the main cause of smog.
By absorbing the harmful fumes back into a car’s fuel system, a car’s evaporation control system not only helps make for a cleaner engine but also helps to keep the environment safer for habitation.Learn more about Car Parts & Maintenance
An EGR valve helps to improve the performance and economy of a vehicle while reducing emissions by directing exhaust gases back into the cylinders of the vehicle for a second burn. The valve reduces nitrous oxide emissions and directs the warmer exhaust back into the engine, reducing the amount of work required by the fuel-and-air mix in maintaining the engine at operating temperature.Full Answer >
Within an evaporative emission control system, a charcoal canister vent control valve prevents gasoline vapor emissions from escaping into the atmosphere. The Environmental Protection Agency requires that all new cars be equipped with these EVAP systems.Full Answer >
A knock sensor detects engine knock or detonation, which then controls the timing of the engine. Engine knock and detonation are usually harmful engine vibrations that are often caused when a spark plug does not ignite the fuel properly. This will cause the engine to run roughly, and may cause serious damage if not taken care of immediately.Full Answer >
The crankshaft takes the piston from an up and down motion and changes it to a rotating motion. The crankshaft is near the bottom of the engine.Full Answer >
