| 摘要 |
A sensor may be used to measure particulate mass concentration in the exhaust of an internal combustion engine. The sensor may include a signal electrode and a detector electrode at least partially enclosed within a sensor body. The sensor may continuously measure the particulate mass concentration in the exhaust of the internal combustion engine. Continuously measuring the particulate mass concentration may produce a time-resolved measurement of the particulate mass concentration. In certain embodiments, the sensor may be coupled to a feedback control system that may adjust operating conditions of the internal combustion engine.
