Camshaft
The camshaft opens and closes valves that allow for combustion to occur.
Connecting Rod
Is the part of a piston engine which connects the piston to the crankshaft
Engine Exhaust Outlet
Is where the gases are released to the exhaust manifold.
Fresh Air Intake
The component that directs the fresh air to each of the engine's intake valves or ports.
Oil Intake Screen Assy
A strainer located at the lower end of the oil pickup tube in sump to remove large contaminant particles.
Oil Pump
Pressurized oil lubricating oil to circulate within the engine moving parts. The pumped oil also maintained the temperature of the engine.
Pressurized Air Outlet
Push Rod
A metal tube designed to transfer the reciprocating motion of a valve lifter, riding on the camshaft, to the valve.
Rocker Arm Adjuster
Allows adjustment of the valves.
Rocker Arm
A reciprocating lever used in an internal combustion engine to transfer cam or pushrod motion to a valve stem.
Rocker Cover
Bolted on over rocker arms in an internal combustion engine.
Turbocharger Exhaust Inlet
The exhaust turbocharger comprises a turbine and a compressor between which there is a fixed mechanical connection established via a common shaft.
Turbocharger Exhaust Outlet
(also called the "hot side" or "exhaust side" of the turbo) is where the rotational force is produced, in order to power the compressor (via a rotating shaft through the center of a turbo.
Valve Lifter
Cylindrical component that rides on the Cam Shaft to actuate the Intake and Exhaust Valves.
Crankshaft
The crankshaft is one of the most intricate parts of a diesel engine. This piece operates on a rotary movement, almost like a bicycle. This sentiment is true for the camshaft, as well. The crankshaft remains closed, holding down the air and fuel mixture needed for combustion until sensors tell them it’s time to open, consequently making the automobile start.
Fuel Injection Pump
the device that pumps fuel into the cylinders of a diesel engine
Fuel Injector
Is one of the most important parts of a diesel engine. These components release diesel gas into the combustion chamber where it mixes with air, and the ignition starts the vehicle.
Glow Plugs
Heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine.
Intake Valve
In the cylinder head of an internal-combustion engine that opens at the proper moment in the cycle to allow the fuel-air mixture to be drawn into the cylinder.
Oil Drain Plug
Is a screw plug made of metal or plastic. The oil drain plug with sealing ring seals the drain opening. This opening is needed to drain waste oil when changing the oil before refilling.
Oil Pan
Is a metal dish that covers the bottom of the engine block. It serves as a reservoir that keeps the engine oil which from its oil circulate around the engine. Read: Understanding Engine Lubrication System. There is a pickup tube from an oil pump that enters into the sump and sucks up the oil.
Piston
Is a metal cylinder which moves up and down inside the engine cylinder through varying stages of the combustion cycle, which is connected to the engine's crankshaft via a connecting rod.
Piston Rings
Form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil sump.
Precombustion Chamber
Space in which combustible gases are ignited and combustion started ahead of the main combustion chamber of a jet or gas engine The glow plug is an electrically operated device that protrudes into the precombustion chamber.
Starter Motor
(also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
Starter Solenoid
Is an electromagnet which is actuated to engage the starter motor
Valve Spring
Used to hold closed a valve in the cylinder head of an internal-combustion engine
Wrist Pin
Connects the piston head to the connecting rod. A wrist pin is a pin through the skirt of a piston in an internal-combustion engine, to which the little end of the connecting rod is attached.
