The Engine is the vehicle’s most expensive component, so it is key to monitor its operation to act in a timely manner and safeguard its integrity, to meet this objective our client has implemented our Engine Analysis and Protection solution in its fleet.
The solution provides Engine Protection automatically under certain circumstances:
The Engine Protection is executed in the vehicle when Risk Conditions for the Engine occur, that is, when the maximum and minimum predetermined values are reached or exceeded, in order not to compromise its operation and avoid excessive wear, mechanical failures and high costs for parts and repairs.
Constant “Low Engine Oil Pressure” Alerts and Notifications began to be received in several fleet’s vehicles, which caused the units to execute their Engine Protection process, which involves stopping and shutting down the vehicle safely to prevent damage.
Although Protecting the Engine was achieved, the final customer’s Passenger Transport service was being affected in terms of quality and reputation by these interruptions, so it was a priority to identify the causes that generated the problem.
Through a Detailed Analysis of the parameters recorded throughout the operation’s historical behavior, it was possible to identify a pattern in the operation of some units of the fleet at the time of generating the “Low Engine Oil Pressure” alert.
What parameters were analyzed?
In the cases reviewed, it was found that when the vehicle suddenly slows down (km/h) the alert generates, when the necessary conditions are present to activate the alert.
The “Low Engine Oil Pressure” alert was configured to run when a value equal to or less than 1 bar was presented. When taking a unit as reference, the following behavior was identified:
The Big Data deep analysis of the collected Telemetry Data allowed us to identify the units that presented events and also the managements to which they belonged, with the aim of executing an action plan according to the severity level.
The analysis time period was 2 months, sufficient for the problem identification and for the solution implementation.
The first that had to be analyzed was the existence of a behavior pattern in the units that presented the alert, for which the groups of units were divided to determine if there was a group or unit in the particular that had a higher alerts rate.
In the 1st month of analysis, 13 units were identified that registered 373 Motor Protection events due to Low Engine Oil Level, with the Central Region accounting for 80% of the cases.
With this information, it was possible to review with the maintenance management of the Central Region and inform them about the causes of why there were failures in the operation.
The first thing was to suggest an oil levels review and implement corrective actions in the identified units, the same was suggested for the East Region, while the 3 missing regions did not present any related event.
Once the corrective actions were carried out in the Central Region, which consisted of oil refills, a significant improvement was identified in the 2nd month.
This corrective action generated a positive impact, reducing the number of events by 78.5%, and the number of units by 53%.
Taking these couple of months into consideration, the 1st month concentrated 83.9% of the total alert events, while the 2nd month represented only 16.1%.
Based on this analysis and customer feedback, the following conclusions could be obtained:
When a vehicle has a Low Engine Oil Level, and sudden braking happens, it causes a surge in the tank, which together with air presence in the Engine Oil System, causes an Oil Low Pressure.
Through these results, the Oil Levelswere loaded to the optimum operating range, in the same way a Maintenance Campaignwas created to check oil levels and detect tank leaks for the rest of the fleet.
The analysis was considered as an opportunity to prevent future alerts and above all, failures in the engines of your vehicles, as well as high costs for repairs, in this way Didcom® Telemetry Solutions help to avoid risk situations before they even present.
Vehicles can be sent to Preventive Maintenance before a failure occurs, avoiding its impact on the operation and ensuring the business profitability.
Engine Protection helps to minimize downtime, providing a better quality service, ensuring end-customer satisfaction and strengthening your reputation in the market.
Didcom® Telematics Solutions are a smart investment that gives a competitive advantage to your Autotransport Company, facilitating the registration and analysis of valuable information about your Fleet to avoid unnecessary expenses for engine repairs or replacements.
