As hybrid vehicles incorporate electric motor drives, engine development targets have shifted toward improving thermal efficiency and reducing fuel consumption. This led to the introduction of engine technologies such as TGDI, Miller/Atkinson cycle, high compression ratio, low-pressure EGR, and low friction loss. Weifu Tianli has conducted in-depth development for hybrid engines, such as turbocharger performance matching simulation technology, efficient compressor and turbine design, high-pressu
