Chevrolet Cruze RVC Technology to Boost Fuel Economy

March 29, 2011, By Sanjeev Ramachandran

With demand for ultimate fuel economy proving to be the main factor in automobile purchase decisions these days, Chevrolet has tread on to a new terrain by employing a new technology for their Cruze.

Known as Regulated Voltage Control (RVC), the new patented technology from General Motors has been brought in so as to improve the fuel economy of the vehicle. The technology works in various steps.

The power that runs from the alternator to the battery of the vehicle is reduced from 14 volts to 12.8 volts under normal driving conditions with the RVC.

The alternator converges on the power on the vehicle’s electrical loads, which in turn, avoids charging the battery with current that is not required by it. Thus by reducing the voltage to the battery, the demand on the alternator is also reduced.

Obviously, the alternator’s pull on the engine is reduced by way of this. This mechanism allows the engine to run more efficiently.  The fuel economy, is thereby, improved with the enhancement in the working of the engine.

According to Doug Dickson, an electrical engineering specialist with the GM Global Energy Center, the technology will help improve fuel economy on the Cruze by up to 1.5 percent. He further added that RVC enables more than eight additional miles of range on every tank of fuel, which sounds too good.

Other advantages of the new technology is that, when the battery is fully charged, RVC supplies some of the power to handle the load created by electronic gadgets  – such as the radio. This further reduces the electrical demands on the alternator and the engine.

On the other hand, when the battery charge is low, the alternator automatically extends the necessary voltage to recharge the battery. The battery, thus remains fully charged even it handles more of the vehicle’s electrical load, through automatic recharging.

Sounds like this could be the advent of an amazing technology on the green terrain.
