Engine Parts
What is the purpose of the piston in a four-stroke engine?
To compress the air-fuel mixture and transfer the force to the crankshaft.
Which stroke is responsible for compressing the air-fuel mixture in a four-stroke engine?
The compression stroke.
What is the purpose of the cooling system in a four-stroke engine?
The purpose of the cooling system in a four-stroke engine is to prevent the engine from overheating.
What tool is used to tighten fastener to specific weight?
Torque Wrenches
Which component is responsible for opening and closing the valves in a four-stroke engine?
The camshaft.
During this stroke in a four-stroke engine, the burned gases are expelled from the combustion chamber.
Exhaust Stroke
Which system delivers fuel to the combustion chamber in a four-stroke engine?
The system that delivers fuel to the combustion chamber in a four-stroke engine is the fuel injection system or carburetor.
This tool have long, thin jaws and can reach into recesses
Needle Nose Pliers
What is the function of the crankshaft in a four-stroke engine?
To convert the linear motion of the piston into rotational motion.
The purpose of this stroke in a four-stroke engine is to draw in the air-fuel mixture into the combustion chamber.
Intake Stroke
What is the function of the lubrication system in a four-stroke engine?
The function of the lubrication system in a four-stroke engine is to reduce friction and wear between moving parts.
This tool is used to drive pins from bores
Punches
What is the role of the camshaft in a four-stroke engine?
To control the opening and closing of the valves at the right time.
Which stroke is responsible for igniting the air-fuel mixture in a four-stroke engine?
The combustion stroke.
Which system is responsible for starting the engine in a four-stroke engine?
The system responsible for starting the engine in a four-stroke engine is the ignition system.
These 2 tools are used on piston rings in installation on the piston and into the cylinder head
Ring Spreaders and Compressors
What is the function of Push Rods
To connect the camshaft to the valves, transferring motion to open and close the valves at the right time
Why is achieving proper compression important for engine performance?
Achieving proper compression is important for engine performance as it ensures efficient combustion and power generation.
What is the role of the ignition system in a four-stroke engine and what are two ignition system components?
The ignition system in a four-stroke engine is responsible for igniting the air-fuel mixture in the combustion chamber. Two components of the ignition system in a four-stroke engine are the spark plug and the ignition coil.
This tool is used to measure pressure developed
Compression Tester
