7. The best fuels for compression ignition engines are
    (A) Straight chain paraffin
    (B) Aromatics
    (C) Branched chain paraffin
    (D) Naphthalene

8. An oil filter bypass valve opens when the
    (A) Engine is cold
    (B) Engine overheats
    (C) Oil filter becomes clogged
    (D) Engine runs at high speed

9. Damper is also known as

    (C) Spring
    (D) Radius rod

10. The main characteristics of a maintenance free (MF) battery is that
    (A) A maintenance free battery requires little maintenance during normal use and it is sufficient to add water instead of an electrolyte containing sulphuric acid
    (B) A maintenance free battery has a relatively short shelf life when compared with standard batteries
    (C) Since it is sealed, the water in maintenance free battery is not lost through evaporation thus accordingly it is not necessary to top up the cells with water

    (A) Enable the pump's fault diagnosis function to operate
    (B) Warm up and lubricate the pump
    (C) Supplies a large amount of fuel and thereby creates a choke effect
    (D) Pressurise the fuel system before the engine is started
