Abstract

The exhaust manifold has a cylindrical aperture which is a close fit around an actuation rod or shaft which is moved forwards and backwards by a solenoid in order to maintain the correct volume / pressure of exhaust gasses which keep the turbo charger at peak operating conditions to eliminate or counteract, as much as possible, the effects of turbo lag. A pressure sensor monitors the pressure in the exhaust manifold at all times and signals the solenoid to advance or retract the actuation rod or shaft in order to maintain the peak operating conditions required by the turbo charger; ie when low pressure is sensed within the manifold the rod or shaft is advanced to reduce the volume hence instantly increasing the pressure and when pressure too high the rod or shaft is retracted thus reducing pressure hence maximizing the power output of the engine at all times required. An on/off switch may be provided so that the user may start the engine with the invention deactivated if desired.

Description

DFSCRIPTION
Th1it VARIABLE VOLUME MANIFOLD (V V M) AN II NVENTION BY PETER JOHN KENT.
The VARIABLE VOLUME MANIFOLD (VVM) is an invention to counteract the cflcts of what is usually referred to as TURBO LAG which is the time that elapses until the chaust manifold gasses reach optimum pressure within the exhaust manifold, in order to activate the turbo charger to useful means I optimum pressure.
From the sketch it is seen that the \VM incorporates an extendable and retractable rod / shafl to decrease the volume within the exhaust manifold when extended, thus increase the pressure within the exhaust manifold, and increase the volume in the exhaust mamfold when retracted, thus reduce the pressure within the exhaust manifold. A pressure sensor to determine pressure, that is when low pressure is sensed the rod / shaft is moved forwards to decrease the volume within the manifold hence increase the pressure hence supply the turbo charger with gas at a higher rate much sooner than existing turbo chargers, when pressure higher than desired is felt the rod / shaft may be retracted keeping the turbo charger supplied at an optimum level, a solenoid mechanism to move the rod I shaft forward and reverse as dictated by the pressure sensor. An on -off switch is incorporated so that the engine may be started as per normal if desired, once the engine is started the V V M may be activated so the pressure sensor can initially engage and shoot the rod forward to decrease the volume within the exhaust manifold and so increase the pressure to the turbo charger thus binging the turbo fan to optimum revolutions per minute (rpm) by way of the pressure sensor dictating the initial forward travel distance, thus with the vehicle at standstill on tick over the turbo is already building up to optimum pressure ready to move the vehicle forwards without having the usual time waste of waiting for the engine rpm to get to the higher end of the rev band to activate the turbo charger to useful means, in as much to say the VVM will get the turbo charger at optimum revs / pressure when the engine is still at the low end of the engine rev band maximising power output, a definite advantage over the already existing turbo charger operation. -\-
