Design and Simulation of an Electronically Controlled Single-Cylinder Diesel Engine to Lower Emissions
Publication: Journal of Energy Engineering
Volume 143, Issue 5
Abstract
Single-cylinder diesel engines are widely used because of their low cost and high adaptability, and they have become the main power for industry and agriculture in developing countries. The inability of meeting increasing requirements for energy saving and environmental protection have become the primary bottleneck problems for diesel engines. The high cost of various advanced technologies for emission control limits their application. In this study, an economic single-cylinder diesel engine to lower emissions is designed. The four-valve technology and high-pressure injection system with electrical unit pump are adopted. Both the numerical simulation and experimental results indicate that the fuel consumption can be 10% lower than that of other engines on the same power level. The noxious gas emission has been measured up to the emission standards in China, the United States, and Japan on nonroad diesel engines. Meanwhile, the life-cycle cost of the new engine consisting of initial and maintenance expenses is lower than traditional engines. The technology of the economic single-cylinder diesel engine proposed in this study is believed to have remarkable market value and deep impact to the governmental decision makers, and to greatly contribute to easing the sharp conflict between economic development and environmental pollution, especially in developing countries.
