Product Code:SAE J2548
Title:Test Method to Obtain Lug-Up Torque Data for Heavy-Duty Truck and Bus Engines
Issuing Committee:Truck And Bus Advanced And Hybrid Powertrain Steering Comm
Scope: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. The 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.【英文标准名称】:Rubberhosesandhoseassemblies-Textile-reinforcedhydraulictypes-Specification-Part2:Water-basedfluidapplications
