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specification of Single-fuel Natural Gas Vehicle Engine The normative references in the former standard have been superseded by other references; therefore, this revision focuses on the changes of the references.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. Chief drafting staff of this standard. Dou Huili, Yan Tao, Wang Yu, Yu Guifang. PROFESSIONAL STANDARD OF THE PEOPLE'S REPUBLIC OF CHINA Technical Specification of Single-Fuel Natural Gas Vehicle Engine
