                        Variable Torque Enhancement Systems

“Variable Torque Enhancement Systems (VTES) are PCM controlled inductive turbines instantly boosting engine power.”

“VTES systems combined with exhaust energy recovery systems will radically change hybrids as we known them today.”

A “Hybrid  describes 2 technologies blended into one: electric motors and gas engines as we have today.  

What exactly is a “Hybrid Four”* concept? Briefly, 2 more technologies added to the Hybrid cars of today.

1.      Use of a 1/3 smaller gas motor than the size engine found in Hybrid use today, for better mileage when cruising

2.      Hybrid individual electric wheel power is applied for acceleration and regenerates battery power during braking

3.      Inductive motor intake turbine will pressurize intake charge on demand, canceling out the smaller displacement. AndThe VTES engineers designed use stored battery power compresses the intake to produce 20-40% more free engine torque.

4.      Exhaust exiting the engine still contains energy now recovered in a turbo driven generator charging the battery. The VTES engineers recover waste thermal energy in the exhaust to drive a turbine coupled to a 6 kW generator. This concept stories previously wasted heat energy for later VTES or individual wheel motor power again improving overall thermal efficiency and with it big gains estimated to 70 MPG to the “Hybrid Four”.

 “The electric powered supercharger also can react more quickly, spinning up to 70,000 rpm in less than 350 milliseconds to provide the power boost precisely when the driver needs it. ” said Pierre-Emmanuel Strohl, Valeo’s Product Marketing Director of Powertrain Systems, at a media briefing in late July 2012 at the company’s North American headquarters in Troy, MI. “The VTES supercharger, compatible with both gasoline and diesel engines, uses electric power rather than the crankshaft to inject air into the engine and boost output. Because it is decoupled from the engine, there’s no power drag that forces the power plant to burn more fuel and produce higher levels of unwanted emissions. Tests have shown exhaust generators can produce 6kW of energy to the batteries to store”

“A VTES system equipped car then routes battery power to an inductance 12V supercharger that quickly produces instantaneous boost. The electrically driven supercharger works in conjunction with the fuel management to produce instant boost and lower emissions all-the-while using less fuel.”  Strohl continues.  The two devices together are claimed to improve fuel economy by 20%. French supplier Valeo has plans to supply new technology to help certain car manufacturers to each the 56 MPG our US EPA mandated for the year 2025. Engineers found the immediate response of inductive turbines, when combines with exhaust energy recovery generators powering the huge batteries in hybrid vehicles the best way to reach 60-70 mpg in a car not too different from today’s cars. 

Engineers estimate carbon-dioxide emissions could be reduced 15%-25% in a vehicle using the micro-hybrid technologies at a cost of $1,000-$2,000, well below what it says is the $2,100-$13,000 outlay for mild, full and plug-in hybrid powertrains. VTES (for variable torque enhancement system), could be beneath the hood of a production vehicle within 12 month. Nick Pascoe, chief executive officer CPT says: “use of the electric supercharger could help prevent future fuel-economy-focused powertrains that combine downsized engines with high-ratio transmissions from “driving like a dog.”

A 30% reduction in engine size can translate into a 15% reduction in CO2, Pascoe tells WardsAuto in an interview prior to the technology sale to Valeo last year “That’s a big improvement, but will anyone buy it? (This) gets you back to being (both) green and fun to drive.”
