A Study on the Suitable Compression Ratio of Hydrogen Fueled Engine with Dual Injection

Hydrogen fueled engine with dual injection can achieve high power and high efficiency simultaneously. In this study, the suitable compression ratio of hydrogen fueled engine with dual injection were investigated including performance of this engine according to variation of compression ratio. As results, it was found that the suitable compression ratio of that was about CR=11, and torque and thermal efficiency increased by 6% and 7% respectively.
