REVOLUTIONIZING THE GAME BEETWEEN
EV and ICE

AKS ACTIVE Patented technology A transformative Leap for ICE engines in the EV Era

"Revolutionary thermodynamical model for ICE engines, regulating heat transfer within milliseconds cycle"

AKS ACTIVE is a revolutionary breakthrough technology capable of reducing fuel consumption by up to 30% backed by patent number DE112017000942.1T 2019. This is achieved through the application of specialized material layers, leading to the thermal activation of the combustion chamber. AKS is an active combustion chamber of a piston engine with an innovative thermal structure, in which excess heat (previously dissipated to the radiator) and portions of exergy (previously expelled with exhaust gases) are internally stored along with the engine's operating cycle. This leads to a revolutionary utilization of fuel, with minimal engine upgrade costs.

To understand the future it's good to understand the past

Evolution of heat cycle in combustion chamber

a) Carnot’s sketch of hypothetical heat engine (1824)

b) Internal combustion heat engine, e.g. Newcomen first steam machine (1712) or Stirling engine (1816);

c) Internal combustion steam engine, e.g. Reithmann (1873) and later work by Otto (1876) – with a passive combustion chamber (BKS);

d) Thermally insulated passive combustion chamber BKS, e.g. as studied by Woschni (1986) under the auspices of BMW and Daimler;

AKS is an innovative design of a piston engine which overcomes limitations in efficiency set out in the second law of thermodynamics and the ideal hypothetical Carnot heat machine of 1824.

e) AKS ACTIVE – Author’s proposal to develop the passive combustion chamber (BKS) into an active combustion chamber (AKS).

Key:

A – source of heat; B – source of cold (ambience); C – radiator (external cooling);

1 – thermal buffers (BT) retaining portions of excess heat; 2 – thermal buffers (BT) retaining portions of anergy; 3 – sinks of exergy in the form of mechanical energy included in calculation of energy streams balance determined by source and sink.

exergy

– energy stream per mechanical work

anergy

– residual energy from thermodynamic

transformation, excreted through exhaust

excess heat

– heat exhausted from combustion

chamber contents for protection of fuel from thermolysis

Thermally insulated layers applied in combustion chambers can revolutionarily reduce fuel consumption e.g. from 6 dcm3 to below 4 dcm3 per 100 km, and CO2 emissions by over 45 g/km.

Birth of the Invention

„After several decades of designing and implementing industrial innovative automation systems, we initiated our own work on a combustion chamber regulation for internal combustion engines, closing within milliseconds, which was not even theoretically resolved. The goal was to eliminate the paradoxical need for simultaneous heating and cooling. This was Rudolf Diesel’s dream. We began by developing prototypes of our own engine („Flawless Wankel”). Collaborating with TU Breslau and TU Warsaw, we achieved a mechanical breakthrough, but not the ultimate objective. However, from the analysis of the work emerged the groundbreaking idea of thermally active combustion chamber, which does not require a new design”.

"It is a thermodynamic revolution, without a mechanical one”

HOW IT WORKS ?​

The essence of the technology, as well as its simplicity, lies in adjusting the appropriate surface area and thickness of AKS THERMAL and AKS ISOLATE layers relative to the parameters of a given engine. This allows for directing energy in the combustion chamber precisely where it is needed at a given place and time. As a result, heat is always where it is most needed – a task already handled by the natural processes of thermodynamic processes, which are often misunderstood or incompletely understood.​

AKS ACTIVE LAYERS

Caution: This is a simplified description. In practice, the exact parameters of the AKS active layers are calculated individually for each engine, following calculating sheets and the patented specification.

AKS THERMAL

Example SURFACE: 30 CM2 WIDTH: 0.1 MM

AKS THERMAL is designed to store heat when the chamber heats up, so that it can be released back into the combustion chamber during the next stroke of the engine. Under normal conditions, heat would dissipate to the radiator and be lost!

AKS ISOLATE

Example SURFACE: 30 CM2 WIDTH: 0,1 MM

This layer is designed to retain excess heat generated in the combustion chamber. The principle of operation is similar to that of a thermos. We don't want the heat to escape, so we store it inside, thereby insulating it from the external temperature.

Rudolf diesel in 1890's was dreaming about reusing heat portions within the engine

After over 120 years and many decades of research thanks to AKS ACTIVE this process have been discovered and backed by thermodynamical model based on fundamental laws of physics and mathematics such as conservation of energy

100J

IS ABSORBED AND RELEASED WITHIN MILISECONDS TIME-CYCLES BY AKS THERMAL LAYER RATHER THAN WASTED IN COOLING SYSTEM

That’s as little portion of heat energy as boiling a small glass of water.​
