Engine monitoring method

Abstract

A method of monitoring the usage of an internal combustion engine is provided. The method comprises performing an engine monitoring routine using a local monitoring device directly attached to an internal combustion engine. The engine monitoring routine includes generating a plurality of data points representative of the crankcase pressure of the internal combustion engine using a pressure sensor of the local monitoring device, processing the generated data points to determine a first value representative of a firing frequency of the internal combustion engine, generating an aggregated summary of the internal combustion engine usage based on the first value, and transmitting identification data for the local monitoring device and the aggregated summary from the local monitoring device to a remote application. The remote application processes the transmitted aggregated summary based on the transmitted identification data to determine engine speed usage data for the internal combustion engine.
