ISX12 G and ISL G Cold Weather Operation
Cold weather affects CEGR SI natural gas engines
differently compared to CEGR CI diesel engines
Natural gas engines are susceptible to sub-freezing
intake air
Too cold intake air forms condensation in charge air
coolers and freezes intake components
Measures MUST be taken to insure adequate intake air
temperatures are maintained
18
Cold Weather Operating Aids
Coolant, Oil and Battery Heaters, Warm Intake Air,as well as Radiatior
Shutters/Winter Fronts are required for engine operation below 11 F (-12 C)
Starting Fluid
Due to potential engine damage, starting fluid should not be used.
The use of starting fluid in a gaseous fueled engine has no practical purpose.

Excerpt
from ISL G
Owners
manual.
Natural Gas Range
Natural gas engine mpg lower than diesel
– Lower compression
– Throttled inlet versus fuel injected
Example:
– Diesel fuel economy 5 mpg
– Natural gas fuel economy 4.5 mpg
Diesel Fuel Storage 60 g = range 300 miles
CNG Fuel Storage 60 dge = range 270 miles
Important to look at cost per mile as natural gas fuel cost is typically less than diesel.
