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.

A comparative study on mean value modelling of two-stroke marine diesel engine [PDF]

open access: yes, 2009
In the present paper, two mean value modelling approaches of varying complexity, capable of simulating two-stroke marine Diesel engines, are presented. Both approaches were implemented in the computational environment of MATLAB Simulink®. Simulation runs

On the Rigidity and Mechanical Behavior of Triply Periodic Minimal Surfaces‐Based Lattices: Insights from Extensive Experiments and Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

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 ...

A Two-Stroke Range Extender Engine For Heavy Duty BEV applications [PDF]

open access: yes, 2020
A back-up range extender (REX) is proposed to support battery electric vehicles (BEV) for heavy duty applications. A single cylinder crank case scavenged two-stroke SI-internal combustion engine (ICE) with a turbocharger system is considered powerful and

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.

SCS: Superior‐Vena‐Cava Compressing Shape‐Memory‐Alloy‐Based Implantable Device for Heart Failure

open access: yesAdvanced Engineering Materials, EarlyView.
An implantable superior–vena‐cava compression device, utilizing biocompatible shape‐memory‐alloy actuators, regulates blood flow and thereby achieves an 18.6% reduction in end‐diastolic left ventricular volume in a porcine model of ADHF. This potential long‐term solution minimizes thrombosis risk by avoiding direct blood contact, offering a significant

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 ...

Quantum Analog of Carnot Engine [PDF]

open access: yesarXiv, 2017
In order to build a quantum analog of traditional Carnot engine, a common choice is replacing the two thermodynamic adiabatic processes with two quantum mechanical adiabatic processes. In general, such quantum Carnot engine has six strokes. We analyze the efficiency of such six-stroke quantum Carnot engine in a perturbative way.
