Efficiency of Six-Stroke Engines: A New Era in Motor Technology


The Six-Stroke Engine represents a significant advancement in motor technology, offering a cycle of six strokes with two power strokes. Unlike traditional four-stroke engines, six-stroke engines combine both external and internal combustion, leading to increased efficiency and reduced emissions.

Mechanics and Design

The six-stroke engine differentiates itself with a modified cylinder head featuring two additional chambers: one for combustion and another for air heating. This separation allows for more design flexibility and results in a notable increase in thermal efficiency. The engine operates on two cycles: an external combustion cycle and an internal combustion cycle, each consisting of four events.

Advantages Over Traditional Engines

The six-stroke engine boasts several advantages:

  • Increased Thermal Efficiency: Due to its design, it has a greater change in volume during the power stroke compared to intake and compression strokes, enhancing efficiency.
  • Reduced Fuel Consumption: It can potentially reduce fuel consumption by 40%, offering significant economic and environmental benefits.
  • Lower Emissions: The six-stroke engine dramatically reduces emissions, contributing to a cleaner environment.
  • Multi-Fuel Capability: Capable of operating on a variety of fuels, it offers flexibility in fuel choice, including less polluting options.

Constructional Details

The six-stroke engine’s construction includes a cylinder head equipped with four valves, two of which are conventional (intake and exhaust), and two made of heat-resisting material for the additional chambers. The combustion chamber walls are designed to be thin to facilitate heat exchange, enhancing efficiency.

Operation and Efficiency

In operation, the six-stroke engine is thermodynamically more efficient, with an operating efficiency of approximately 50%. This is a significant improvement over the 30% efficiency typically observed in petrol engines. The engine’s design also allows for smoother operation at low speeds, making it particularly effective in urban driving conditions.

Future and Impact

The adoption of six-stroke engines in the automotive industry could have a profound impact on both the environment and the global economy. With the potential for up to 40% reduction in fuel consumption and 60% to 90% reduction in emissions, depending on the fuel type, the six-stroke engine presents a promising future in motor technology.


The six-stroke engine offers a practical solution to improving current internal combustion engine technology. Its efficiency, reduced fuel consumption, and lower emissions position it as an innovative alternative with the potential to reshape the automotive industry.
