Integral Powertrain Ltd, of which Intrinsys is a division, has developed an exciting new pressure charging technology which will enable a new generation of highly efficient, downsized automotive engines that exhibit very low CO2 emissions and excellent driveability.
Market Drivers - Energy demand for transportation is increasing but global energy supply is rising at a slower rate, limited by many practical and economic factors. The need to reduce fuel consumption is clear, but consumers remain strongly driven by a desire for “fun to drive” vehicles, demanding increased performance.
One route to reducing fuel consumption & CO2
emissions is the use of a smaller capacity engine; however torque enhancement is required to achieve the required performance. Turbochargers are an efficient boosting system, but suffer from response lag while superchargers offer poor efficiency and present significant NVH challenges.
SuperGen System
How does the SuperGen system work?
SuperGen incorporates an efficient continuously variable drive by combining an epicyclic traction drive with a high efficiency electric motor. The SuperGen system combines two drive paths, one mechanical and one electrical.
Mechanical drive: Power comes in to the SuperGen unit from the crank via a belt, driving a ring “gear” at 2.5 times engine speed. If the planet hubs are held stationary, the sun wheel turns at 13 times input speed (32 times engine speed).
Electrical drive: If the engine were stationary and the small control motor were to turn the planet hubs , the sun would turn at 14 times motor speed.
Combined drive: The compressor speed is the sum of the mechanical & electrical drive; as a result the compressor can be modulated accurately between 0 & 225,000rpm.
SuperGen Improves Driveability - SuperGen enhances vehicle driveability by improving low speed and mid range torque by up to 22 percent. This allows a 1.4 litre engine with SuperGen to have 10% taller gearing and still comfortably exceed the tractive force provided by a 2.0 litre baseline engine.
