Valve Misfire Detected and Corrected without Expensive Repair
What happened?
Advanced Condition Monitoring a digital service under Cat® Connect uses analytics along with expert advisory Services to transform data into actionable information. Analytics detected a misfire on two cylinders of a G3608 engine of a remotely monitored unmanned natural gas compressor station based in the United States. The customer was able to take the necessary steps to resolve the issue and keep the unit running.
What action was taken?
The Fleet Advisor recommended that the pre-chamber needle valve be temporarily adjusted, then returned to its normal position if minor clogging occurred in the valve. This procedure stopped the misfire.
What is the value to the customer?
The customer benefited in several ways:
- No unnecessary parts replacement. The issue was corrected without replacing the parts (spark plugs and check valves). As a result, the customer didn’t lose the value remaining in the existing parts and didn’t have to spend approximately $1,250 for replacement parts and the labor to install them.
- No lost revenue from an unnecessary shutdown. Because the situation was resolved without an inspection or repair, production wasn’t interrupted unnecessarily.
- No unscheduled downtime. The proactive valve adjustment reduced the risk of a future failure that could have resulted in an unscheduled outage and lost production estimated at $1,500.
The total value derived from this single issue is approximately $2,750. The cost of the service is $400 per month at 98% run time.
