1. A mass airflow sensor measurement correction system for a turbocharged diesel engine operating under transient conditions, comprising:
- a engine speed signal input device that receives an engine speed signal based on an engine speed of a turbocharged diesel engine; and
a control module that receives said engine speed signal and that calculates a correction value of mass airflow from a differential of said engine speed signal and a first constant and that applies said correction value to a measured mass airflow value.

Abstract
A mass airflow sensor measurement correction system for a turbocharged diesel engine operating under transient conditions includes a signal input device that generates an engine speed signal based on an engine speed of a turbocharged diesel engine. A control module receives the engine speed signal and calculates a correction value of mass airflow from a differential of the engine speed signal and a constant.
