Engine construction Basics
The engine block is usually made of these two materials.
What is Cast Iron and Aluminum?
This harnesses the power from the gas getting ignited inside the cylinder.
What is Piston?
When the piston moves 1/2 way down the bore, the crankshaft moves _____ than that distance around its rotation.
What is Less?
"Having a 3 inch lift and 2019 wrangler tires/ rims helps it move off road with no problems. The inline 6 engine is very reliable and in great shape for being an older vehicle. Its faded blue exterior is scarred with the memories of camping, snowboarding, and riding on dunes. Once the engine has given its last breath, it will receive a 4 cylinder turbo charged diesel engine that will greatly improve its MPG and performance."
What is Mr. Keim's Jeep?
This lubricates all of the internal components of the engine, and should be changed every 5000 miles of operation.
What is Engine Oil?
The engine block is a very sophisticated _______. Although it is also machined as part of its construction.
What is Casting?
What is the Flywheel?
The flywheel is only used to carry the engines inertia between power strokes and reduce engine vibration.
True or False?
What is False? (It also is holds the starter gear)
"The I-Beam style design transfers the piston force down to the crankshaft. The small end contains the piston pin and the big end has a removable cap to install it to the crank."
What is Connecting Rod?
Oil rings are usually made up of ______ part(s).
What is 3 parts?
The four main types of engine block configurations talked about in class.
What is Vee, inline, opposed (box), and Slant?
Converts the reciprocating motion into rotary motion.
What is the Crank Shaft?
Name the number and names for the different strokes the piston makes during a cycle of the engine.
What is 4 strokes: Intake, compression, power, and exhaust?
"Even if you have catastrophic timing issues with this engine, you are NOT at risk of damaging your values or pistons. This is because it is designed in a way where even if the vales are open and the pistons are at top dead center, there is no chance of them coming into contact."
What are Free Running Engines?
This is the main difference between gaskets and seals.
What is Gaskets are between two stationary parts, while seals are between moving components?
Aluminum engines have this part in them that other engine styles do not.
What are Cylinder Sleeves?
These are used to hold the compression in the engine as well as keep the oil from entering the cylinder.
What are Piston Rings. (There are 2 compression, and 1 oil ring)
Cylinders are always numbered in this order so that mechanics always understand which one they are looking at.
What is Front to back?
"This style of engine does the best job of reducing vibration because of its configuration. Because of the layout of the cylinders, the forces in the engine are offset in a direction that makes the car reduce what the driver feels naturally."
What is Box or opposed engine?
The area of the cylinder that experiences the most wear during the lifespan of an engine.
What is the top of the cylinder?
Besides turning the drive shaft and fly wheel, the crank shaft is also responsible for driving these two other components.
What are the timing belt/chain, and serpentine belt?
Usually made of a steel backing with soft metal on the other side, these create a low friction area during crank shaft rotation.
What are Crankshaft Bearings?
The main difference between Diesel and Gasoline engines.
What is the type of combustion? Diesel uses glow plugs, while gasoline uses spark plugs.
"The pin hole is moved towards the piston's major thrust surface. This is the surface of the piston that is pushed tightly against the cylinder wall during the power stroke. If the pin hole were centered in the piston, the piston could hit the side of the cylinder."
What is Wrist pin offset and Piston Slap?
This "spring" is special because it is the only type of suspension that does not get compressed. Instead it uses a different type of force to create the "Spring" effect.
What is a torsion bar?
