Maximum cylinder pressure should occur in an engine:

• Just before TDC

• At TDC or just after TDC

• At BDC

• At the end of the power stroke

A Wankel engine has the following components:

• Epitrochoid shaped housing and a 3 sided rotor

• Epitrochoid shaped housing and a piston

• Normal pistons and cylinders

• Epitrochoid shaped housing and inlet and exhaust valves

Semi-Synthetic oil is a consists of:

• Is a lubricant that is man made

• Is a pure mineral base oil

• Is a mixture of man made and organic oils

• None of the above

The small, usually clear, tank connected to the radiator in the cooling system will:

• Allow water to flow into it but not out of when the coolant expands

• Allow water to flow into it but not out of when the coolant contracts

• Allow water to flow into and out of when the coolant expands or contracts

• A convenient place for the radiator cap to fit

An engine with 1 camshaft controlling the inlet valves and 1 camshaft controlling the exhaust valves is known as:

• 2 camshaft engine

• DOCH

• DOHC

• Dual camshaft engine

An engine has low oil pressure – this could be caused by:

• A camshaft engine with leaking exhaust valves

• Leaking oil control rings

• Worn main bearings

• A seized closed PRV

An engine has a leaking oil pump and this may cause:

• Engine oil loss

• Leaking oil control rings

• Blue smoke

• Low engine oil pressure

Crankshaft end float on a fully assembled engine is best measured with a:

• DMM

• DTI

• Feeler gauge

• Crankshaft end float measuring tool

During a compression test it is found that Cyl No 2 increases significantly with a few drops of engine added to the cyl bore:

• Indicates that the valves are leaking

• The valve timing is incorrect

• The oil control ring is worn excessively

• None of the above.

The engine stroke is best measured with a:

• D.T.I

• External Micrometer

• An Engineering steel rule

• None of the above
