Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Single-cylinder 125 CC stepped piston engine for mobility and portable power generation applications [PDF]

open access: yes, 2015
Two-stroke engines is far simpler than four-stroke version from its physical perspective. For a given brake output, two-stroke is lighter, easier to work on, and provide higher power-to-weight ratio than the four-stroke, making it suitable for small ...

Development of a 2-Stroke GDI Engine

open access: yesEnergy Procedia, 2017
Abstract Nowadays, high-pressure gasoline direct injection (GDI) can be considered a standard technology, due to the wide application on 4-stroke turbocharged engines. This technology – in combination with other specific solutions - has been successfully applied to a 500 cc, 30 kW 2-stroke engine, initially developed as a range extender.

Electronic Control System for Optimized Resonance Operation of Dielectric Elastomer Pumps through Self‐Sensing

open access: yesAdvanced Engineering Materials, EarlyView.
A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Mathematically analysis on two stroke uniflow scavenging system [PDF]

open access: yes, 2007
Conventional 2-stroke engines are commonly used for two-wheeled and marine vehicles that have small engine displacement. However problems such as unstable combustion, high fuel consumption rate, high hydrocarbon (HC) emission need to be resolved.

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

open access: yesAdvanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

The zero-dimensional model of the scavenging process in the opposed-piston two-stroke aircraft diesel engine

open access: yesPropulsion and Power Research, 2019
The analysis of the scavenging process in two-stroke engines is important in terms of achieved performance and emission of toxic substances. The amount of mass of air used for the scavenging process and the amount mass of gas retained in the cylinder ...
