pumping engine

Owing to the totally elimination of the throttling action to the air inflow, this kind of unthrottled SI engine can greatly decrease the pumping loss, which makes the fuel consumption reduce 10-15% under small and medium-sized load.

由于完全取消了节气门对进气的节流作用，这种无节气门汽油机将大幅度地降低泵气损失，使中小负荷时的燃油耗降低10-15%。

Comparison and preliminary analysis are made between two design schemes of pumping with exhaust blower and injecting with injector for the investment and energy consumption in operation at given engine exhaust conditions.
