Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube. [citation needed]. This system maintains a small amount of vacuum in the crankcase and minimises the amount of oil in the engine that ...
In a typical system, vapors from the fuel tank and carburetor bowl vent (on carbureted vehicles) are ducted to canisters containing activated carbon. The vapors are adsorbed within the canister, and during certain engine operational modes fresh air is drawn through the canister, pulling the vapor into the engine, where it burns.
If the car's own vapor recovery system is working properly, then the Stage II nozzle will only be vacuuming normal fresh air and depositing that into the gas station's underground fuel storage tanks. That ends up causing evaporation of fuel vapors into the atmosphere, because too much pressure builds up in those fuel storage tanks.
It could also cause issues for the occupants of the car as it could be drawn into the inside of the car, which was often unpleasant. Around 1961 a new design was created. This design routed the crank breather into the intake of the car. This meant that the vapors and oil mist could be burnt and expelled out of the car through the exhaust.
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled ( fuel pump ) or released (pressurized gas) into an engine .
The term cylinder in this context is sometimes confused with tank, the latter being an open-top or vented container that stores liquids under gravity, though the term scuba tank is commonly used to refer to a compressed gas cylinder used for breathing gas supply to an underwater breathing apparatus.
Catalytic converters in cars intend to break down the pollution of exhaust gases using a catalyst. Scrubbers in ships intend to remove the sulfur dioxide (SO 2 ) of marine exhaust gases. The regulations on marine sulfur dioxide emissions are tightening, however only a small number of special areas worldwide have been designated for low sulfur ...
The most common diesel tank designs are cylindrical, rectangular and D-Style tanks. Cylindrical designs are often selected for their visual appeal while the rectangular tank is most often employed to maximize fuel volume for a given space. The D-Tank, as its name implies, is actually a hybrid of the cylindrical and rectangular designs.
