Measuring Engine Performance
What is determined by the distance the piston moves from TDC to BDC
Stroke
What is Stored Energy
Potential Energy
This is often used in conjunction with a tap to ease the friction when cutting.
Oil or Cutting oil
Engine design which develops a power stroke every other revolution of the crankshaft
Four Stroke Engine
The engines found in midsize snow throwers range in what hp size?
3-8 HP
Refers to the total volume of space inside in the cylinder when the piston moves from the top to the bottom of its Stroke.
Displacement
A series of events or operations that happen regularly and lead back to the starting point.
Cycle
When you have a suspected engine problem. This is uses air pressure from hose to decipher where the problem is.
Leakdown Tester
Area between the piston and cylinder head when the piston is at the top of its stroke.
Combustion Chamber
For best performance, a snow thrower engine should be ran at
High Speed
The relationship between the total cylinder volume when the piston is at the bottom of its stroke (BDC) and the volume remaining in the when the piston is at the top of its stroke (TDC).
Compression Ratio
Energy that is the most flexible and is best known for lighting lights, running motors, and providing communications.
Electrical Energy
What octane rating does Honda recommend for their GX engines?
86 octane or higher
Attached by the manufacturer giving their Name, Engine Make, Model, Serial Number and other information that could be helpful when looking up parts of service material
Name Plate
Used to protect the auger and gearbox in the event something gets lodged in the auger housing.
Shear Bolt
The force that holds you to the ground.
Centripetal Force
Energy cannot be created or destroyed.
Characteristic of Energy
This is a coating of steel, bronze, tin and other metals to allow for better wear characteristics.
Babbit
Has detailed procedures for all aspects of machine repair.
Service Manual
10W oil
This indicates the actual usable horsepower delivered at the engine crankshaft.
Brake Horsepower
Increase Force, Change Direction, Change Speed
Uses of Simple machine
This helps a four stroke engine "breath" better.
Valve Overlap
The Engine Must be completely sealed otherwise it will not function properly.
Two-stroke Engine
This regulates the height of the scraper bar.
Skid Shoes or Skids
