THE MECXIC™ ENGINE

The MECXIC INTERNAL COMBUSTION ENGINE INNOVATIONS are the result of a fundamental re-thinks of how internal combustion engines turn heat into work.

They are targeted at increasing the longevity of the internal combustion engine via the following benefits:

• The design promises significant improvements to both fuel consumption and a reduction in exhaust gas pollutants.
• The improvements come at a time when the worldwide search into finding a viable replacement for the IC engine appears to be stalling on cost, safety and environmental lifecycle factors.
• The MECXIC INTERNAL COMBUSTION INNOVATIONS have been carefully engineered to achieve anticipated performance improvements via a policy of:

Minimising complexity, avoiding exotic materials, complementing current IC engine technologies, utilising engine mass production facilities, running on existing fuels and lubricants, preserving the low maintenance/high reliability features expected of traditional IC engines.

WHAT IS THE MECXIC CONCEPT ?

The underlying philosophy of the MECXIC ENGINE is the ECCENTRIC EXPANSION of the combustion gases within a traditional piston/cylinder/crankshaft configuration. This ensures that more of the heat produced by combustion is recovered as useful work - giving direct benefits in improved specific fuel consumption.

However, the MECXIC ENGINE  has several other less obvious but equally beneficial spin-offs:

• This eccentric expansion reduces the temperature of the exhaust gases significantly – savings on cooling and lubrication components and materials are anticipated.
• The mechanical configuration ensures almost complete purging of exhaust gases from the cylinder as the piston is configured to sweep the combustion chamber space also.

The above two factors combine to significantly reduce the high temperature re-combustion of exhaust gases – a major source of unwanted NoX emissions from a ‘traditional’ IC engine.

• Due to the eccentric power stroke of the MECXIC engine, the facility to introduce exhaust ports into the cylinder barrel is exploited, resulting in reduced thermal loadings in the cylinder head area, and lower mass flow of high temperature gases through the conventional exhaust valve.
• As a consequence of the above factor, a combined inlet/exhaust valve becomes a practical alternative - saving on manufacturing, maintaining and driving separate exhaust valve gear while allowing optimum sizing and positioning of the combined inlet/exhaust valve(s) within the cylinder head.
• A higher torque is produced during the power stroke due to the inherent mechanical configuration of the MECXIC engine.
• Thermal efficiencies calculated by assuming an adiabatic expansion of the combustion gases shows increases of between 15 and 18% in a practical engine running a 1:2 eccentric expansion ratio.
