Abstract:

One of the most attractive combustive features for hydrogen fuel is its wide range of flammability. The wide flammability limits allow hydrogen engine to be operated at extremely lean air-fuel ratios compared to conventional fuels. Concepts for part-load operation of hydrogen engines have been proposed using quantitative control and qualitative control. This paper summarizes the steady-state test results by quantitative and qualitative air-fuel ratio control modes in a hydrogen internal combustion four-cylinder engine operated on an engine dynamometer. Based on the test results of engine efficiency and NOx emissions, a combinated air-fuel ratio control strategy for hydrogen engine is proposed.

I. Introduction

The automobile industry is facing the ultimate stage approaching zero regulated emissions as well as substantial reductions in CO2 emissions. As the most plentiful element in the universe, hydrogen has long been recognized as a desirable fuel in engines[1]. Its combustion does not produce any of the major pollutants such as CO2, HC and smoke. NOx is the noly pollutant needs to be carefully controlled. Thus, hydrogen is probably the unique versatile fuel which provides permanent solutions to fuel depletion and global environmental problems.
