Modeling of specific fuel consumption for compression ignition engines fueled with polymer-based fuel: a response surface methodology approach

Engineering Research Express
Abstract Background. Diesel engines play a crucial role in ensuring human comfort and well-being across residential, commercial, transportation, and emergency response sectors because of their reliability and versatility. However, identifying alternative fuels remains a significant challenge. Objective. This study aims

Lean air-fuel mixtures supplemented with hydrogen for S.I. engines: A possible way to reduce specific fuel consumption?

International Journal of Hydrogen Energy, 1985
Abstract From a theoretical viewpoint, a lean or ultra-lean mixture improves thermal efficiency of internal combustion engines when operating at partial loads. This is confirmed is current practice with compression-ignited motors. However, spark-ignited engines actually reach the lowest specific fuel consumptions at air-fuel ratios not very far from
