Diesel engine start of fuel injection detecting system |
摘要 |
An electrical pressure signal that varies directly in magnitude with changes of fuel line pressure at the fuel injector is raised to a selected mathematical power. This signal is then differentiated to detect the negative rate thereof that occurs at the point of inflection upon the start of fuel injection and a "start of fuel injection" output signal is produced in response to the detection of the point of inflection as indicated by the negative rate.
