About

G-Drill is a manufacturing and mechanical engineering design company in Piraeus, Greece. For the past 3 years, we have been focused almost exclusively on the design and manufacture of an innovative Internal Combustion Engine, based on our patented design, that allows us to control the kinematic motion of the piston and hence, create a cleaner, more efficient, and more powerful combustion. More info about our LESS innovative technology can be found on its own website, https://less-engineering.com/

Solution & Product

Our basic innovation lies in our patented mechanism for converting reciprocating motion to rotary motion and vice versa. This is called the LESS mechanism, and itself has many applications, from Pumps, to Compressors, to Internal Combustion Engines. We've already built a prototype for a compressor using our patented design, and we are currently building a pump and an internal combustion engine. Right now, we are focusing on our 2-cylinder, 4-stroke, 413cc petrol engine prototype, which will be completed, tested an evaluated soon.

Innovation & Scalability

Internal Combustion Engines in particular have a lot of disadvantages and flaws, but they are still wonders of engineering, and they get the job done. With LESS, all of the proven technologies and solutions are kept in place, and we merely improve a key component that allows us to do the same job, only better. With a lighter and smaller mechanism. Since it doesn’t affect the thermodynamic cycles of traditional engines, the LESS mechanism is applicable to all kinds of ICEs (Diesel, Gasoline, LPGs etc). Even better, we can improve them! With LESS, the combustion can be designed specifically as wanted, resulting in increased performance and efficiency. For example, we can introduce a delay in the Top and Bottom Dead Centers of the piston (via the undulated surfaces’ design, see Kinematics section for more info), and fix a shortcoming of the crankshaft mechanism resulting in high energy losses and low-efficiency ratio due to the imperfect combustion. The delay in the Top Dead Center enables a near-perfect isochoric combustion and better mechanical conversion of the pressure in the combustion chamber into work. Because our mechanism makes 2 (or more) reciprocations per full rotation, it completes one full combustion cycle in 360 degrees. As a result of this, we produce the same work as traditional designs at half the RPMs but twice the torque, as you can see on the right, cutting the amount of gear reduction required by half.

Traction & achievements

As mentioned, so far we have built 2 prototypes, one as a pump, and one as a compressor, to verify the basic components of our mechanism. We have also designed our first petrol engine prototype, which will be our first near-market-ready and proof-of-concept prototype, showcasing our design's advantages.

Team & Why Us

The principal innovator behind the patent, George Georgitzikis, has decades of experience as a mechanical engineer, has designed dozens of innovative products, and is the author of two more patents. The CEO Vasilis Georgitzikis is a serial entrepreneur having started his first VC-backed company in 2011 at the age of 23.

Funding Needs

We are not currently seeking any funding. We will start seeking funding after we have measured and proven the success and benefits of our current prototype.
