CPT’s engineering portfolio includes its award-winning SpeedStart technology, which can be cost-effectively applied to a wide range of gasoline and diesel engines. The technology is more advanced than many existing stop-start systems and lends itself to heavy usage and premium vehicle applications; providing a powerful, refined and controllable stop-start solution that is far more efficient and can be used more often. “Only by maximising the number of stop-start events can fuel consumption and CO2 emissions be significantly reduced,” says Pascoe. “Its potential for energy recovery under braking is also considerable.”
The world’s first bespoke belt-driven integrated starter generator (B-ISG) to operate at 12 volts also resolves all the issues that initially made car makers reluctant to introduce stop-start. As the name implies, SpeedStart can restart an engine in half the time of a conventional starter motor and is currently the best stop-start technology able to cope with ‘driver change of mind’; an all too frequent occurrence when drivers suddenly have the opportunity to drive on, but with conventional stop-start systems the engine has already reached the point of no return and can no longer be prevented from shutting down before it can be restarted. SpeedStart also allows the driver to leave the vehicle in gear, meaning it’s unobtrusive and there is no change of driving behaviour required of the driver.
Other CO2 reducing technologies from CPT include the company’s launch ready VTES electric supercharger. Unlike a turbocharger or crankshaft driven supercharger, the CPT method of boosting is completely independent of engine speed and offers precise electronic control. No matter how low the engine revs, the 2kW booster remains highly responsive and fast acting. This crucial difference means the technology is perfectly suited to maintaining vehicle performance and driveability - now widely recognised as a critical marketing issue for down-speeded vehicles with taller gearing or more radical engine downsizing.
Completing the line-up of CO2 reducing technologies is CPT’s innovative TIGERS turbo-generator for exhaust gas energy recovery, which is currently under development. Coupled to an exhaust driven turbine the air or water cooled device is intended to generate electrical power during steady state cruising. Exhaust gases provide an efficient and underutilised method of power regeneration, particularly for a throttled gasoline engine, and can further help improve fuel economy and reduce CO2 emissions.
All three technologies have been applied to a number of technical collaborations and development projects with leading car makers, engine developers, Tier 1 suppliers and engineering consultancies. “With all three technologies there is very little modification to the base engine design or vehicle electrical architecture enabling vehicle manufacturers to apply them at relatively low cost,” says Pascoe. Other potential applications include fuel cell electric vehicles and emission reduction in diesel engines.
Controlled Power Technologies was set up in 2007 as a management buy-in funded by venture capital initially to acquire advanced powertrain technologies from Visteon Corporation and its technology development partner Emerson Corporation. CPT comes with a highly experienced team of automotive engineers and is backed by a number of prominent investors specialising in the energy and environmental sectors.
