3.16 Environmental Conditions
The Multec 3.5 Fuel Injector is designed to operate in a certain range of
conditions but can withstand extreme operating conditions for short
periods of time. Table 3-2 lists typical examples of normal and extreme
operating conditions. Refer to the Engineering Product Specification for
the application for exact values and conditions. Values shown are for
example purposes only. Specific application values may vary. Extreme
operating conditions are for short durations only with possible degraded
performance.
