The actual amount of power delivered to the propeller shaft is called ___________ .

The number of crankshaft degrees that the intake valve opens before the piston reaches top dead centre is called ____________?

Four-stroke diesel engine operating cycle is similar to the Otto cycle, except that the diesel engines use the compression-ignition principle and has ignition system components.

One of the strokes that begins as the piston moves past BDC and begins its upward stroke.

The number of pounds of fuel used to produce one horsepower, either indicated or brake is known as ___________?

Usually, back-firing occurs in carburetted engines that are running rich where the air fuel mixture has insufficient fuel.

All certificated aircraft engines have dual ignition, which means that there are two independent ignition systems, firing two spark plugs in each cylinder.

__________ is defined as a normal combustion process starting before the ignition spark is initiated.

The factor/s that affect the engine power are:

Its main purpose is to transform the reciprocating motion of the pistons and connecting rods into rotary motion to turn a propeller.

The component passing the air/fuel mixture from the carburettor to the induction ports of the cylinder head.

The link which transmits the force exerted on a piston to a crankshaft.

The __________ in a reciprocating engine is a cylindrical plunger that moves up and down within a cylinder.

What are the the two types of oil rings that are found on most engines?

Prevent gas from escaping past the piston during engine operation and are placed in the ring grooves immediately below the piston head are called ________________.

It acts as a lid on the cylinder barrel to provide an enclosed chamber for combustion.

It meters fuel according to the pressure difference between the downstream side of the fuel jet and the net pressure of the fuel in the float bowl

Its basic purpose is to provide optimum engine efficiency for any given flight condition.

A part of lubrication system that prevent excessive pressure from damaging an engine.
