High pressure common rail system failure detection

A system, comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:
• receiving, from a first oil pressure sensor, first oil pressure data associated with oil directed to an engine of a machine;
• receiving, from a second oil pressure sensor downstream from the first oil pressure sensor and upstream of a high-pressure pump supplying fuel to the engine, second oil pressure data associated with oil bypassing the engine and directed to the high-pressure pump;
• determining, based at least in part on the first oil pressure data and the second oil pressure data, an impending failure associated with the high-pressure pump;
• and
• sending, over a communication network, an indication of the impending failure to a computing device associated with an end user of the machine.

A system comprising:

• a first oil pressure sensor for measuring input oil pressure flowing to an engine of a machine and a high-pressure common rail (HPCR) pump associated with a fuel distribution system of the machine;
• a second oil pressure sensor downstream of the first oil pressure sensor and upstream of the HPCR pump, the second oil pressure sensor being configured to measure the input oil pressure of oil bypassing the engine and flowing to the HPCR pump;
• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:
• determining, based at least in part on first oil pressure data generated by the first oil pressure sensor, a first oil pressure value associated with the input oil pressure flowing to the engine and the HPCR pump;
• determining, based at least in part on second oil pressure data generated by the second oil pressure sensor, a second oil pressure value associated with the input oil pressure flowing to the HPCR pump;
• determining a difference between the first oil pressure value and the second oil pressure value;
• determining an impending failure associated with the HPCR pump based at least in part on the difference and the second oil pressure value;
• and
• sending, over a communication network, an indication of the impending failure to a computing device associated with an end user of the machine.
