Research on the Performance and Emission of a Port Fuel Injection Hydrogen Internal Combustion Engine

摘要：

A 2.0L nature aspirate gasoline engine was modified to port fuel injection (PFI) hydrogen internal combustion engine (HICE) and a series dynamometer tests were carried out. The in-cylinder combustion process was analyzed, the performance, thermal efficiency and emissions of HICE with various mixture eqivalence ratios was summarized. The experimental results showed: While 20-25％ lower torque compared with gasoline is observed for this naturally aspirated hydrogen engine, peak efficiencies of 45 ％ were achieved with brake thermal efficiency above 30％ over a wide range of operating conditions. NOx emission was quite a little when the mixture equivalence ratio lower than O.SS or higher than 1. NOx emission reached peak level at equivalence ratio between 0.8 and 0.9. Finally the hydrogen engine was installed in a vehicle and the vehicle emission fully satisfied the Euro VI emission standard.
