    Urutan Langkah Kerja mesin yang tepat adalah

    • Hisap-buang-kompresi-usaha

    • Hisap-kompresi-buang-usaha

    • Hisap-kompresi-usaha-buang

    • Kompresi-hisap-buang-usaha

    Correct Answer
    A. Hisap-kompresi-usaha-buang
    Explanation
    The correct answer is "hisap-kompresi-usaha-buang." This is the correct sequence of steps for a machine. First, it needs to "hisap" or suck in something. Then, it compresses or "kompresi" the sucked-in material. After that, it puts in effort or "usaha" to do something with the compressed material. Finally, it "buang" or disposes of the material.

    Komponen dalam mesin yang berfungsi mencampur bahan bakar dan udara adalah ?

    • Karburator

    • Katup

    • Poros engkol

    • Noken as

    Correct Answer
    A. Karburator
    Explanation
    The correct answer is karburator. A karburator is a component in an engine that is responsible for mixing fuel and air in the correct ratio before it enters the combustion chamber. It regulates the flow of fuel into the engine based on the throttle position, ensuring that the engine receives the right amount of fuel for combustion.

    Berikut ini adalah syarat terjadi pembakaran yang sempurna pada motor bensin kecuali......

    • Campuran bahan bakar dan udara

    • Percikan bunga api

    • Kompresi

    • Bahan bakar

    Correct Answer
    A. Bahan bakar
    Explanation
    The correct answer is "bahan bakar". In order for complete combustion to occur in a gasoline engine, four main elements are required: fuel, air, spark, and compression. The fuel and air mixture needs to be in the correct ratio for efficient combustion, a spark is needed to ignite the mixture, and compression helps to increase the temperature and pressure within the combustion chamber. Therefore, all the options mentioned (except for "bahan bakar") are necessary for complete combustion to occur.

  • 5. 

    Pada saat langkah hisap, posisi katup masuk dan buang adalah ?

    • Katup masuk membuka, katup buang menutup

    • Katup masuk membuka, katup buang menutup

    • Katup buang membuka, karup masuk menutup

    • Katup masuk menutup, katup buang menutup

    Correct Answer
    A. Katup masuk membuka, katup buang menutup
    Explanation
    During the suction stroke, the intake valve opens to allow the fuel-air mixture to enter the combustion chamber, while the exhaust valve remains closed to prevent the escape of combustion gases. This allows for efficient intake of the fuel-air mixture into the cylinder for the next combustion cycle.

    Rate this question:

  • 6. 

    Pada saat langkah kompresi, sebelum piston mencapai TMA busi memercikan bunga api pada titik?

    • 10 derajat

    • 20 derajat

    • 30 derajat

    • 40 derajat

    Correct Answer
    A. 10 derajat
    Explanation
    During the compression stroke, the piston moves towards the top dead center (TDC) position. Before the piston reaches the TDC, the spark plug ignites the air-fuel mixture in the combustion chamber. This ignition point is known as the spark advance. The question asks at what point before the TDC the spark plug ignites the mixture, and the correct answer is 10 degrees. This means that the spark plug fires 10 degrees before the piston reaches the top dead center position.

  • 7. 

    Komponen mesin yang berfungsi memercikan bunga api adalah....

    • Busi

    • Radiator

    • Koil

    • Dinamostarter

    Correct Answer
    A. Busi
    Explanation
    The component of the engine that functions to ignite the spark plug is the busi.

    Rate this question:

  • 8. 

    Berapakah jumlah sylinder pada mobil L 300 ?

    • 2 sylinder

    • 3 sylinder

    • 4 sylinder

    • 5 sylinder

    Correct Answer
    A. 4 sylinder
    Explanation
    The correct answer is 4 sylinder. This means that the L 300 car has 4 cylinders.

    Rate this question:

  • 9. 

    Komponen berikut terdapat pada mesin diesel, kecuali?

    • Karburator

    • Head sylinder

    • Radiator

    • Poros engkol

    Correct Answer
    A. Karburator
    Explanation
    The given options are components that are typically found in a diesel engine. However, the carburetor is not typically found in a diesel engine. Diesel engines use a different method of fuel delivery called direct fuel injection, which eliminates the need for a carburetor. Therefore, the correct answer is karburator.

    Rate this question:

  • 10. 

    Pada saat langkah buang, posisi piston adalah?

    • Dari TMA menuju TMB

    • Dari TMB menuju TMA

    • Di TMA

    • DI TMB

    Correct Answer
    A. Dari TMB menuju TMA
    Explanation
    Pada saat langkah buang, posisi piston adalah dari TMB menuju TMA.
