Common Engine Terms

Bore Stroke Compression Ratio Displacement Horsepower

Page 6: Engine systems   diesel engine analyst - full

Bore Size

The diameter of the cylinder

Measured in inches or millimeters

Page 7: Engine systems   diesel engine analyst - full

Stroke

How far the piston moves from TDC to BDC

Equal to twice the crank radius

Page 8: Engine systems   diesel engine analyst - full

Compression Ratio

Ratio between the cylinder volume with the piston at BDC and the volume with the piston at TDC

Compression ratio of our engines are approximately a 16:1 (non-ACERT) and 18:1 (ACERT)

Page 9: Engine systems   diesel engine analyst - full

Displacement

Engine size is expressed in liters or cubic inches

Displacement = X Stroke X No. of Cyls. (3.14 X B 2 )

Page 10: Engine systems   diesel engine analyst - full

Horsepower is the rate of doing work (how quickly a force is applied through a distance)

Horsepower can be expressed in pound feet per second

1 horsepower = 550 lb/ft per second

= 33,000 lb/ft per minute

Horsepower

Engine Model Numbers

3208 Engine: 3200 = Engine Family & Relative Size

(3000, 3200, 3300, 3400, 3500, 3600)

08 = number of Cylinders

be 04, 06, 08, 12, 16, 18, or 24

Page 12: Engine systems   diesel engine analyst - full

3116 Engine 3100 = Engine Family

11 = 1.1 liters per cylinder, so:

3126 has 1.2 liters per cylinder

3176 has 1.7 liters per cylinder

6 = number of cylinders (4 or 6)

Heat exchanger for inlet air

Series of metal tubes through which hot inlet air flows

Heat from the air flowing from the tubes is absorbed through the tube walls and carried away

2 types Air to air (ATAAC) Jacket water (JWAC)

Aftercooling

Page 54: Engine systems   diesel engine analyst - full

Most common cause -- failure of the turbocharger compressor wheel

Damages aftercooler tubes Coolant leakage into inlet air stream

Poor coolant maintenance may cause pitting/corrosion of the aftercooler tubes

Results in water to air leakage Hydraulic lock on the engine

Causes of Premature Wearout & Failure of Aftercoolers

Page 55: Engine systems   diesel engine analyst - full

Flow of the coolant begins at the water pump

Pump impeller creates the flow

Water pumps are gear or belt driven

Water pump seals

Separates engine oil from coolant

Water Pump

Page 56: Engine systems   diesel engine analyst - full

Engine coolant flows from the water pump directly into the oil cooler

Oil carries heat away from critical engine parts

Heat is transferred from the oil to the engine coolant

Page 63: Engine systems   diesel engine analyst - full

Causes of Cooling System Wear & Failure Single most common problem – poor coolant quality

Due to… Not maintaining adequate levels of coolant additives Using coolant that does not meet Cat’s specifications Not keeping the cooling system topped off Using coolant past its useful life

Other problems include: Coolant to air leaks in the aftercooler

Causes hydraulic lock Radiator or hose failures

From reusing old radiators and hosing Failure to service the coolant relief valve

… most cooling system problems can be avoided with proper maintenance practices!

Page 64: Engine systems   diesel engine analyst - full

Cooling Systems

Coolant flows around cylinder liners

Absorbs heat from the combustion chamber

Prevents breakdown of oil film between pistons and liners

Page 65: Engine systems   diesel engine analyst - full

Cooling Systems

Coolant flows through passages in the cylinder block into the cylinder head

Water seals between the head and block prevent coolant leaks

Some engines have water ferrules to direct coolant to critical areas

Fuel System Wear & Failure Causes Short unit injector life due to excessive abrasive particles in

the fuel Abrasive particles damage sealing surfaces causing leakage of

high pressure fuel and low engine power Abrasive particles are inherent in most fuels Most particles can be removed by using High Efficiency filters

Injector seizure due to excess water in the fuel Always small amounts of water in fuel, which is harmless Excess water in fuel reduces the lubricating film strength of fuel

and causes seizure of the injector plunger and barrel Maximum amount of allowable water in fuel is 0.1%

Page 88: Engine systems   diesel engine analyst - full

Fuel System Wear & Failure Causes Injector sticking or seizure due to fuel overheating

Fuel in the injector “cooks” and produces varnish which causes components to stick or seize

Viscosity of hot fuel is inadequate and the fuel film thickness will not provide adequate protection against scuffing or seizure of the plunger and barrel

Fuel overheating can be caused by operating in extreme ambient temperatures. An auxiliary fuel cooler installed in the fuel supply line to the cylinder heads may be required to limit fuel temperatures

Running fuel tank too low, or running out of fuel causes the fuel to cycle through the engine too frequently and becomes very hot. This can be avoided by keeping the fuel tank levels at ¼ full or above

Page 89: Engine systems   diesel engine analyst - full

Fuel System Wear & Failure Causes Poor quality oil

Fuel may be low in viscosity or lubricity. Fuel which is old or oxidized often contains excessive gums or resins which promotes injector sticking or seizure.

Nickel Ring Band Pistons

Page 128: Engine systems   diesel engine analyst - full

PistonsFeatures• Nickel-band ring• Specially ground, tapered• Controlled casting process• Precise fit

• Lowered chance of seizure • Less downtime caused by part

failure• Lower operating costs

Advantages• Better sealing • Proper bonding• Less blow-by • Less carbon deposit • Delivers more power• Longer wear• Reusable

C7 Piston

Page 129: Engine systems   diesel engine analyst - full

One Piece Steel Piston

• Increased structural capability• Machined from a single steel forging

• Eliminates need for a separate aluminum skirt & possible breakage

• Eliminates possible debond of ring groove• Reduced thermal expansion allows piston fit

to be tighter for a reduction in liner cavitation• Reduction in surface area provides less

friction and helps fuel consumption • Higher Oil Flow

• Bigger piston oil gallery & new oil jets• Runs cooler thus reducing piston carbon deposit

and oil consumption• New ring pack

• 25% reduction in blow-by • No bushings to replace in 3408 & 3412

Used on 3408, 3412, 3500 & all ACERT engines

What is Remanufacturing?

Differences between RepairRebuildRemanufacture

Page 140: Engine systems   diesel engine analyst - full

Usually simple Fixes only a specific

problem May not use genuine CAT

parts depending on labor source.

Repair

Page 141: Engine systems   diesel engine analyst - full

Usually retains the component identity More than a simple repair Usually done by dealer, customer or

re-builder Restores to near original condition May not use genuine Cat parts Re-builder assumes the warranty

liability Requires investments in tools, equip.,

training, etc Rebuild and return or exchange –

turnaround time involved

Rebuild

Page 142: Engine systems   diesel engine analyst - full

Consistent factory environment Process and quality control Upgrades to latest engineering

changes Harvest components (looses its

original identity) Uses 100% genuine Cat parts Cat Reman carries standard parts

warranty Requires cores – exchange only
