ELECTRIC SUPERCHARGER FOR VEHICLES THAT NEEDS A POWER BOOST

Today, there are a lot of latest innovations that comes out of the streamline. This is because of the continuous needs of many car owners from around the world. Performance is one of the main reasons of this. So here’s the good news, Controlled Power Technologies has developed a quick and excellent technical solution for the predicament when it comes to downsizing’ engines without compromising drivability and performance – the electrical supercharger. CPT’s low-cost production-ready variable torque enhancement system or VTES utilizes an electrically driven supercharger on demand (within 350 milliseconds) when the driving conditions demand it. The VTES can be implemented on current vehicles, using existing 12 volt electrical architecture, and when used in series with a turbocharger, the 2kW of electrical power translates into 20kW at the crankshaft.

 

Basically, downsizing the engine is considered as one of the most cost effective means to vehicle CO2 reduction. The European automakers have already moving rapidly towards the 30% reduction in displacing the mid-sized engines to around 1.4 to 1.6 litre capacity while offering the potential to provide up to 15% reduction in CO2 emissions. However, this downsizing trend will only be successful if the technology used is cost effective and at the same time the driving experience is still satisfying and sustaining the needs of the mass market consumer. Hence, the market success for the automakers is also influenced by their ability and that is to improve or maintain the vehicle drivability at the lowest possible total system cost.

 

In order for the smaller engine to become effective and survive in urban environments, they should be equipped with instant full torque availability so that the driver will be able to acquire an excellent acceleration. This responsiveness is important to avoid fuel from being wasted since the driver can select the low ratio gears to keep up with traffic low. To make it possible, smaller engines will usually need some good and reliable boosting systems. But nowadays, there are much simpler and more cost-effective solutions which can help prevent the systems from becoming more complex and expensive than the engine itself.

 

The creation of VTES is intended for these needs. The Variable Torque Enhancement offers a full boost within 350 milliseconds and can improve low speed torque response for an optimum turbocharged gasoline and diesel engines. This new masterpiece can be implemented on the new generation of vehicles using a 12volt electrical architecture and is more effective than any equivalent mild hybrid solution.

 

The CPT VTES system utilizes an electric motor driving a supercharger compressor that delivers an air charge to the vehicle engine for a short period of time, that is, when the driving conditions requires it. Meanwhile, its transient boost maximizes the engine torque at low engine speeds. Every time is used in series with the series conventional turbocharger. It usually gives out a 2KW electrical power that translates into 20KW at the crankshaft. Other advantage is that the possibility of battery draining is minimal and its charged is being restored by the engine alternator.

 

VTES can provide a dramatic increase on the air charge density over the critical first ten combustion cycles of the low-speed transient operation while delivering an excellent improvement both in emission performance and torque where it truly matters most. But it will only be achieved when correctly matched to the engine. Furthermore, its electric supercharger, the CPT family of low powertrain related products features a stop-start system now moving into close production readiness and exhaust energy recovery system in an advanced development stage. The CPT VTES ‘SpeedStart12’ stop-start system can crank up to 2.8-litre gasoline or 2.0-litre diesel engines; it also used standard 12 volt architecture. This part packages into the space of a typical alternator and all of the electronics that are integrated into the unit.

  1. Downsizing engine concept, it just a great concept because it reduces co2. Read it.

  2. For electric car the wheels and the rims should be driven very easily…Then only the driving will be safe…
