Internal Combustion Engine Patent

Taylor IP obtains patent for client Rolls-Royce for Operating an Internal Combustion Engine

This invention optimizes the operation of fuel injectors in an internal combustion engine using a knocking sensor. The knocking sensor detects vibrations within the engine, which correlate with pressure changes in the combustion chamber. These measurements are used to fine-tune the fuel injector’s performance, specifically during the pre-injection phase.

The process begins by recording a signal from the knocking sensor during a specific time window while the injector operates at a fixed energization duration under steady load conditions. This initial data is analyzed using a predefined metric to calculate an evaluation point. Subsequently, the process is repeated with a modified energization duration for the injector, and a second evaluation point is derived using the same calculation method. By comparing the evaluation points, the method identifies the energization duration that delivers optimal performance for the specific load condition. This optimal duration is then stored and applied to improve engine operation.
