REVIEW SIX STROKE ENGINE

, 2017
Now a day the most difficult challenges in engine technology is to increase its thermal efficiency, If the efficiency is higher, than there will less fuel consumption and lower atmospheric emissions per unit of work produced by the engine. In Six Stroke engine, the name indicates a cycle of six strokes in which two are useful power strokes.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation

Advanced Robotics Research, EarlyView.
A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.

Expansion Engine - 4 strokes

This work introduces a novel expansion engine that integrates heat exchange with thermal energy storage and operates on a Quasi-Carnot cycle, combining quasi-isothermal and quasi-adiabatic processes. Unlike conventional combustion, Stirling, or Organic Rankine systems, the proposed design minimizes entropy generation and improves efficiency by using ...
