Abstract

Abstract: In the present study, ZS1115 diesel engine was selected as the test object. Natural gas (NG) intake valve, Venturi NG-air mixer and speed linkage system were mounted with little change in the structure of diesel engine. Three-dimensional (3D) model of dual-fuel engine was established with SolidWorks software according to size parameters, and its practicality was verified with motion simulation. Structural sizes and performance parameters of main parts were optimized with SolidWorks Motion, Simulation Xpress and Simulation Flow modules. Bench test results indicated that the dual-fuel engine based on SolidWorks run stably. Its power performance was greater than diesel engine, while NO_x and smoke emissions were lower. The best economical zone was around 1 700 r·min^-1 in the universal characteristics curve map and the curve extended along the Y axis, which suggested that NG-diesel dual-fuel engine was more suitable for agricultural working condition of low speed and large load changes.

Key words: dual-fuel engine, mixer, inlet valve, SolidWorks, simulation, finite element analysis
