適用范圍：This SAE Recommended Practice applies to all forms of diesel and natural gas engines fueled by the combination of diesel fuel and natural gas. This document provides a method to determine the torque generating capability of an engine as it accelerates away from idle at a specified acceleration rate. The data is typically used to aid in the proper matching of the engine to the available torque converters of a torque converter equipped transmission. This goal is to achieve acceptable off-idle transient engine acceleration against the load of a torque converter equipped vehicle as it moves away from a stop.
