Why Cool ?Why Cool ?Fuel burning engines produce enormous amounts of heat.

Temperatures can reach up to 4,000 degrees during combustion

Normal operating combustion temperature is about 2,000 degrees F.

As fuel is burned in the engine –

1/3 Approx one-third of the energy in the fuel is converted into power.

2/3 Another third goes out the exhaust pipe unused !

3/3 The remaining third becomes heat energy.

This last third is the portion we are concerned with !


Effects of coolingIf a part of the engine gets too hot –• The oil film breaks down and fails to protect internal parts.

• Parts get hotter leading to tighter operation = reduced HP & more fuel used.

• Fuel ‘detonation’ can occur = damage to pistons & Valves.

If an engine runs at too low a temperature-• It is inefficient giving low horse power.

• The oil gets dirty (adding wear and subtracting horsepower).

• Deposits form, and fuel mileage is poor-- not to mention exhaust emissions!

• Direct drive fans cost money and efficiency !!• Power absorbed by ‘Rotating’ fans is high and proportional to the cube of the speed !

• Max. cooling needed as low as 5% of operating time.

• Direct drive fans use this ALL the time, needed or not !

Typical Values:

• 0.12HP ( 90W ) @ 500 RPM.

• 15HP ( 11kW ) @ 2500 RPM.

• 27HP ( 20kW ) @ 3000 RPM.
