Foreword
This standard supersedes QC/T 691-2002 Technical specification of Single-fuel Natural
Gas Vehicle Engine
The normative references in the former standard have been superseded by other
references; therefore, this revision focuses on the changes of the references. The revision is
concentrated on the drainage requirement and test methods of engine and technical
requirements for special natural gas device and its installation. The revision for this standard
covers the liquefied natural gas engine.
This standard is proposed by and under the jurisdiction of the National Technical
Committee on Road Vehicles of Standardization Administration of China (SAC/TC 114).
Chief drafting organization of this standard. China FAW Group Corporation R & D
Center.
