Effect of compression ratio on cycle-by-cycle variations in a natural gas direct injection engine
J Zheng, Z Huang, J Wang, B Wang, D Ning… - Energy & …, 2009 - ACS Publications
Cycle-by-cycle variations of a natural gas direct-injection spark ignition engine at different
compression ratios were investigated. The results show that the lean burn limit of the natural …

Effects of ethanol–unleaded gasoline blends on cyclic variability and emissions in an SI engine
One important design goal for spark-ignited engines is to minimize cyclic variability. A small
amount of cyclic variability (slow burns) can produce undesirable engine vibrations. On the …
