Experimental Investigation for the Design of ECU for A Single Cylinder Engine Using Dual-Fuel (CNG-Diesel)

摘要

The dual fuel CNG-diesel engine is a means for utilizing gaseous fuel resources efficiently in appropriately converted diesel engines. These converted engines can provide an effective method for producing power while reducing exhaust emissions, especially exhaust participates and oxides of nitrogen (compared to the original diesel engines). More efficiency and increased power output, relative to the corresponding diesel operation, can be achieved with dual fuel engines at relatively high loads. However, at light loads, the dual-fuel engines did not run smoothly. This paper explores and compares the performance and emission aspects of an engine when utilizing diesel and dual-fuel. The data acquired are essential for building an Electronic Control Unit (ECU) for a Compressed Natural Gas (CNG)-diesel system, Based on efficiency and exhaust emission measurements, it is concluded that the dual fuel system represents a significant improvement over the original diesel system.
