As early as people used airbag suspension systems“Collide”Before cars, racers realized that moving a car's weight closer to the ground could be reduced, thereby changing handling. is the position of the average car mass. Taller cars roll more around corners and are prone to falling over when carrying someone on your shoulders. When weight is concentrated near the ground, the car becomes more stable. At this point, you may start to wonder what this has to do with the oil system.

Given that the engine makes up a large portion of the car's total weight, it's an advantage to mount it as low as possible. However, there is a problem with the oil pan as it is usually more under the engine6-10inch. exist1950In the 1990s, car manufacturers began looking for a solution to this problem and began experimenting with a radical, racing style that can still be found in performance cars today.

In a wet sump system, the oil sump houses the oil pump and serves as a reservoir for the oil. If you pull the pump out of the oil pan andProcess lubricationThe oil reservoir is removed from the engine and you are left with a shallow oil trap where the oil pan used to be, like the one below2015YearCorvette Z06As seen on the engine. Adding a drain hole to this sump allows the oil to be pumped to the tank, where it can then be degassed (allowed to settle) and cooled using an external oil cooler before being pumped back to the engine.
