Introduction
The Chinese automobile industry is one of the largest and most important industries in the world today, and gasoline and natural gas two-fuel engines are an essential technology for the development of the industry. In order to ensure the steady development of this technology and to improve the quality and reliability of the two-fuel engines, the Chinese automotive industry must abide by the provisions and standards of QC/T 692-2002 Gasoline/Natural Gas Two-Fuel Engine Technical Condition.
Objective
The main aim of QC/T 692-2002 Gasoline/Natural Gas Two-Fuel Engine Technical Condition is to develop and strengthen the mechanical performance and durability of gasoline and natural gas two-fuel engines. It strives to make the engines serve longer and better in order to support the development of Chinas automobile industry.
Content
The QC/T 692-2002 Gasoline/Natural Gas Two-Fuel Engine Technical Condition is divided into eight chapters. It mainly covers the structure, composition, performance and technical requirements of the gasoline and natural gas two-fuel engines.
The first chapter provides general provisions including definitions, application scope, symbols and abbreviations. The second and third chapters focus on the structure, composition and technical requirements of the fuel injection system and air intake system, respectively. The fourth and fifth chapters discuss the performance parameters for the power and torque and fuel consumption, respectively. The sixth chapter is about the basic technical requirements for performances such as acceleration ability and service life. The seventh chapter shows the test methods. Finally, the eighth chapter outlines the requirements for components and material of the two-fuel engines.
Conclusion
QC/T 692-2002 Gasoline/Natural Gas Two-Fuel Engine Technical Condition is the foundation for the development and application of gasoline and natural gas two-fuel engines. It provides important technical requirements and test methods for the development and inspection of the two-fuel engines which will help ensure the steady and safe development of gasoline and natural gas two-fuel engines and the Chinese automobile industry.
