ENGINE OIL VISCOSITY DIAGNOSTIC SYSTEMS AND METHODS |
摘要 |
An engine oil viscosity measurement system is provided. The system includes: a solenoid response module that determines an actual response time based on a position signal; an expected response module that determines an expected response time based on a system voltage and engine oil temperature; and a diagnostic module that diagnoses viscosity of the engine oil based on the actual response time and the expected response time.
