  • Control system and method for limiting engine torque based on engine oil pressure and engine oil temperature data
    Patent number: 8620565
    Abstract: A control system (36) for comparing engine speed data to an engine speed threshold above which the engine is considered to be running (40), for comparing engine temperature data to an engine temperature threshold (60), and once engine speed data has become greater than the engine speed threshold, for causing engine torque to be limited to an engine torque limit until the first to occur of: engine temperature data exceeding the engine temperature threshold, a first timer (44), started upon engine speed data having become greater than the engine speed threshold, having timed to a time that is a function of engine temperature data, and a second timer (54), started upon engine speed data having become greater than the engine speed threshold and engine oil pressure data having become greater than an engine oil pressure threshold, having timed to a time that is also a function of engine temperature data.
