It is the timing of when fuel is injected into the cylinder, which alters when the combustion takes place.
Injector timing
Injection pump timing
Injection fuel timing
Injection timing
It has a lot of holes to deliver a spray of diesel fuel into the cylinder.
Injection system
Injection line
Injection valve
Injector nozzle
Is the device that pumps fuel into the cylinders of a diesel engine.
Injector nozzle
Injection pump
Fuel pump
Injector valve
The fuel is squirted directly into the combustion chamber instead of hanging out in the air intake manifold.
Direct injection
Indirect injection
Common rail injection
Partially injection
Is designed to control the flow of fuel under pressure while minimizing cavitation and vibration.
Plunger valve
Plunger spring
Plunger rod
Plunger retainer
It is in the diesel internal combustion engines in which the injection amount is controlled by the boost pressure.
Pump lever
Pump governor
Pump shut off
Pump housing
Is the process of removing air from the pump and suction line.
Timing plate
Priming pump
Pump timing device
Pump pressure control valve
Is to control the amount of fuel injected into the cylinder.
Pump barrel
Pump control sleeve
Pump delivery valve
Pump camshaft
Is a mechanical device specifically designed to efficiently store rotational energy.
Pulley
Gear
Flywheel
Flange
The bottom section of the fuel filter of an internal combustion engine, serving as the reservoir for water.
Oil trainer
Oil filter
Oil pan
Oil pump
The (a) is designed and fabricated with sufficient
capacity to supply the diesel for at least 6 to 8 hours, and some
times up to 12 hours at its full rated load.
(a) is a primary filtration unit used to remove the water from the diesel fuel before it reaches to the sensitive parts of the engine.
Fuel injection pumps must be supplied with fuel under
pressure because they have insufficient suction ability. All diesel
injection systems require a supply pump transfer fuel from the
supply tank through the filters and lines to the injection pump.
TRUE
FALSE
The (a) atomizes the diesel fuel and spray it into the
combustion chamber.
(a) It is designed and fabricated with sufficient capacity to
supply the diesel fuel for at least 6 to 8 hours.
(a) it is a primary filtration unit used to remove the water from the diesel fuel before it reaches to the sensitive parts of the engine.
(a) This is to prevent the harmful solid particles to reach these
parts and also block the relatively big particles from reaching
the fuel filters.
(a) It is a means to transfer fuel from the supply tank through the
filters and lines to the injection pump.
(a) It is a method to remove foreign particles as well as water.
(a) It is the device that pumps fuel into the cylinders of a diesel engine.
(a) It is to atomize the diesel fuel and spray it into the
combustion chamber.
(a) The pipes should have the same volume so that the
injection pump delivers exact equal amount to the cylinder
injectors.
(a) The type of injection pump uses a single plunger for all Injector nozzles
(a) The type of injection pump uses one plunger for each Injector nozzle.

Cranking compression
Running compression
Loss compression
Compression leakage
The amounts of air/air & fuel mixture escape from the cylinder during compression stroke.
Compression pressure
Compression leakage
Compression stroke
Compression test
The pressure developed in the engine cylinder as the piston move upward at the end of the compression stroke without combustion of fuel.
Compression leakage
Compression ring
Compression pressure
Compression ratio
Worn out piston rings can cause of the following EXCEPT ONE.
Too much fuel consumption
Increase engine power
Engine overheating
Lack of engine power
A metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine.
Piston ring
Piston pin
Piston skirt
Piston slot
It is calculated based on the relative volumes of the combustion chamber and the cylinder.
Compression test
Compression ratio
Compression leakage
Compression pressure
The mechanical component used in internal combustion engines to allow or restrict the flow of fluid or gas to the engine cylinders during engine operation.
Valve spring
Valve guide
Valves
Valve ports
It is a mechanical device specifically designed to efficiently store rotational energy.

Vacuum gauges tester
Bore gauges tester
What is TDC?
(a)
A kind of testing that requires the throttle to be blocked partially opens to allow each cylinder to breathe.
(a)
This leakage gauge uses a metered orifice to create a differential between shop line pressure and cylinder pressure.
(a)
This test is done by starting the engine with a professional grade compression gauge installed in the cylinder.
(a)
It is calculated based on the relative volumes of the combustion chamber and the cylinder that is, the ratio between the volume of the cylinder and combustion chamber.
(a)
This is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase.
(a)
It is a device that pumps fuel into the cylinders of a diesel engine.
(a)
This refers to the ratio of the volume of the cylinder and its head space (including the pre-combustion chamber, if present).
(a)
It is a test that needs to pour out a small amount of oil in the cylinder.
