What is the carter?
Despite its simplicity, the crankcase is considered one of the important elements within an automotive engine, since this is the container that stores the oil in charge of lubricating the engine.
This object also has another important use, which is to seal and isolate the engine block to prevent the entry of contaminants from the outside, since said block contains essential components such as the crankshaft, pistons and connecting rods.
Parts of the sump
Being a container it does not have many parts, we can only find the container, the fastening screws, a gasket to seal the engine block with the crankcase, a plug to drain the oil when a change is required and a rod that is used to measure the oil level.
There are 2 different types: conventional and dry.
automotive , sump , engine parts
Conventional or wet
In this type we can find an integrated submerged pump inside the oil that drives it through the entire lubrication system directly to the engine. due to gravity it returns to its place of origin to be sent back to the engine.
This type is more compact but more complicated in terms of construction since it incorporates an extra step in terms of the operation of the wet sump. As a first step, a pump sucks the oil into an auxiliary tank that is outside the engine, in which we find another pump that is responsible for sending the oil to the engine. It returns to the first tank to repeat the cycle over and over again. This type can also include more accessories such as an oil cooler among others.
Differences between wet and dry sump
One of the main differences is based on the operation, while the wet one sends the oil directly to the engine, the dry one first sends it to an auxiliary tank and then sends it to the engine.
The wet ones are used in everyday cars, while the dry ones are used in race cars due to their lower weight and additional power.
Check oil level
The oil level check is very intuitive as it consists of a dipstick that has the maximum and minimum oil level marked. To make a review we must follow some simple steps:
Leave the car on a flat surface and let it cool so that the oil inside the system returns to the sump.
Take the dipstick out and clean it since the car was in motion the measurement is not valid
insert the dipstick and wait for it to get oil.
Remove the dipstick and carefully observe that it is not outside the recommended levels, either maximum or minimum.
