    Correct Answer
    C. Mencegah oli naik ke ruang bakar
    Explanation
    The correct answer is "Mencegah oli naik ke ruang bakar" (Preventing oil from entering the combustion chamber). When installing the piston rings, it is important for the markings on the rings to face upwards. This is because the rings are designed to scrape excess oil off the cylinder walls and prevent it from entering the combustion chamber. If the rings are installed incorrectly, with the markings facing downwards, they will not be able to effectively control the oil and may lead to oil consumption and potential engine damage.

      Dua ring kompresi dan 2 ring oli

    Correct Answer
    C. Dua ring kompresi dan 1 ring oli
    Explanation
    There are two compression rings and one oil ring on a gasoline engine piston. The compression rings are responsible for sealing the combustion chamber and preventing any leakage of gases during the compression stroke. The oil ring, on the other hand, is responsible for scraping excess oil off the cylinder walls and returning it to the oil sump, preventing excessive oil consumption and maintaining proper lubrication.
