Piston Ring Projection and Catching in Cylinder Ports of Two-Stroke Cycle Engine

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
In a two-stroke cycle engine, the piston and its piston rings slide over the cylinder wall and its cylinder ports. This study investigates how those piston rings project and catch in cylinder ports, and examines the effects of engine speed and round ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

Advanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Photoactive and Ultrastable Silicon/Boron Doped Diamond Photoanodes Enable Longstanding Photoinduced Electrochemiluminescence

Advanced Optical Materials, EarlyView.
This study introduces a highly durable n‐Si/BDD photoanode for photoinduced electrochemiluminescence that entirely circumvents conventional interfacial passivation. By delivering a stable photovoltage under near‐infrared irradiation, the heterojunction facilitates low‐potential optical upconversion.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Optimization of Fuel Injection Control System of Two-Stroke Aeroengine of UAV

Complexity, 2020
Power efficiency of two-stroke spark-ignition engine is generally low because improper amount of fuel injection leads to a lot of unburned fuel loss during the engine working process.

NEW DESIGN OF THE FIVE-STROKE SI ENGINE

Journal of KONES. Powertrain and Transport, 2013
The paper describes design of the five-stroke engine developed in the Chair of Combustion Engines at Cracow University of Technology. The idea of five-stroke engine, in which the expansion ratio is significantly greater than the compression ratio has been presented by the Belgian engineer Gerhard Schmitz.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

Advanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
