4290-152 Quick Revision

On a conventional 4 cylinder 4 stroke engine, if number 1 cylinder is on compression, what stroke is cylinder 4 on?

• Inlet

• Compression

• Exhaust

• Power

Where would you find the correct information on how to remove engine components?

• service book

• workshop manual

• job card

• vehicle log book

What passes into the engine via the inlet valve on a 4 stroke CI engine?

• Air and fuel

• Fuel

• Air

• Heated fuel

Engine stroke is determined by the

• distance between TDC and BDC

• distance travelled by piston during 4 stroke cycle

• internal diameter of piston

• volume displaced by piston between TDC and BDC

In the illustration shown, timing belt tension is adjusted by the component numbered:

• 9

• 13

• 17

• 12

Low oil pressure could be caused by worn

• piston skirts

• oil control rings

• incorrect oil filter

• big end bearings

If the oil control valve sticks on an engine with variable valve timing, it would affect the:

• inlet manifold pressure

• exhaust manifold pressure

• turbo actuation

• valve timing

What is the fault shown in the diagram?

• Burnt exhaust valve

• Burnt inlet valve

• Head gasket failure

• Cracked cylinder head

When fitting a replacement cartridge filter element to an engine lubrication system, it is important to:

• use a sealant on the sealing ring

• put a sealant onto the mounting face

• tighten up the cartridge using a filter strap

• pour some engine oil into the element

What is the main difference between climate control and air conditioning?

• Climate controls the cabin temperature automatically

• Air conditioning controls the cabin temperature automatically

• Climate control reduces cabin temperature only

• Air conditioning raises cabin temperature only
