Energy can be recovered and returned as process make-up air, used to preheat combustion air, or used for plant or office heating.

可以在空气补偿的过程中对能量进行恢复和退回，用于对燃烧空气的再加热或工厂、办公室的加热。

It works by forcing fuel directly into the combustion chamber of each cylinder to mix air and gas simultaneously at the point of combustion, rather than mixing air and gas in a separate chamber like more conventional engines.

The difference between turbocharging and supercharging is simple: a turbocharger boosts engine air pressure by using exhaust gas to power a turbine that pushes more air into the combustion chamber.

One is exhaust gas recirculation, which pumps cooled exhaust back into the engine air intake, lowering the combustion temperature and reducing NOx formation.
