Somender Singh's Design to Improve Turbulence in Combustion Chambers by Creating a Vortex
- Somender Singh says a radical design change to the face of combustion chambers by forming grooves, channels or passages through the squish areas will further enhance in-cylinder turbulence followed by multi flame front combustion. Do-it-yourselfers might consider cutting some grooves in their chambers to approach the effect. (ref)
This PESWiki page is intended to feature the technology and report on results from those who have implemented the design in their combustion chambers.
Introduction to Singh's US patented technology capable of improving fuel consumption & lowering harmful emissions out of diesel & gasoline engines.
This simple 'unconventional' design can improve existing Petrol & Diesel Engines with minor changes to the combustion chamber. This simple design further improves the Thermal Efficiency by burning the Fuel & Air more completely due to quicker & better burn inside combustion chambers. This form of combustion makes more power from the same amount of fuel and expels much less CO2 & other harmful emissions into the air.
Singh's involvements in Motor Sport, Adventure Sport, Aero Sport & Photography in the last 40 years has taught him a lot about Turbulence and its far-reaching effects. All this research led to his Theory: " Design To Improve Turbulence In Combustion Chambers " ~ US Patent 6237579 issued on May 2001. Ever since, he has bettered 100's of 2 & 4 stroke Petrol & Diesel engines with this simple technology. Enthusiasts around the world have also grooved their engines to reap the benefits stated in Singh's patent.
Singh's simple physical design change addresses the most 'stressed out' component of an engine, the combustion chamber where fuel turns into fire! Singh's design deforms the combustion chamber surfaces with grooves to create the desired turbulence to achieve more complete combustion at these moments. The outcome of this discovery was instead of engines cracking up due to the deformities by design, they instead started to perform smoother & better due to the desired turbulence coming at the right moments.
Grooved turbulence has helped Singh to achieve accelerated laminar total clean burn combustion (ALTCBC) in the absence of pre-ignition & knock, and the use of higher compression ratios too. These simple modifications have brought about an ultra wide useable torque band, further improving drivability out of existing engines.
In addition to significantly increased mileage gains, emission tests in approved centers have shown ample proof of reductions in emissions compared to standard engines.

Another Groovy Invention (video) - Somender Singh describes (in English) his patented technology for a Belgian TV station. Says that by putting three simple grooves going into the combustion chamber that mileage can be increased by as much as 50%, through the properly-placed turbulence.

Gadgetman Groove for Boosting Horsepower and Mileage - Ron Hatton's "gadgetmen" use a Dremel tool to cut a groove in the throttle body. The modification takes about an hour and is reversible through epoxy. Somehow, the air turbulence that is set up by that groove has the effect of increasing horsepower, torque, and mileage, while decreasing emissions. (PESWiki; Dec. 7, 2009) (Comment)
