1·Present the advantages of gas-fired absorption chiller-heater, gas-engine chiller and desiccant cooling system.

介绍了燃气吸收式冷温水机组、燃气机驱动的冷水机组和除湿冷却式空调机的优点。

2·As soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

司机一挂上挡，踩下油门踏板，发动机就重新启动了。

3·In testing, the Jetpack could travel at 60 miles per hour for up to 30 miles, and as high as 7,800 feet using a gas engine and two ducted fans.

在测试中，喷气设备可以60英里每小时的速度飞行30英里，通过一个气体引擎和两个管道风扇，可以上升到7,800英尺的高度。

4·In testing, the Jetpack could travel at 60 miles per hour for up to 30 miles, and as high as 7, 800 feet using a gas engine and two ducted fans.

在测试中，喷气设备可以60英里每小时的速度飞行30英里，通过一个气体引擎和两个管道风扇，可以上升到7,800英尺的高度。

5·If the car needs more range, a gas engine kicks in to power a generator that creates additional electricity for the electric motor.

如果汽车需要更多的里程，燃气发动机就投入使用，产生额外的电能来驱动电机。

6·But the star of the show is the Chevy Volt, the electric car with a backup gas engine.
