Parameters Characterizing the Performance of Automotive Electronic Control Systems on Petrol Engine Emissions

Engineering Proceedings
It is evident that a novel engineering solution is required in order to elevate a greater number of polluting cars into a higher category. There appears to be a paucity of direct interest in upgrading Euro 1, 2, 3, 4, and 5 vehicles to the highest ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Adaptability assessment of automobile repair options in terms of product value, environmental impact, and cost (A case study of automobile engines)

Nihon Kikai Gakkai ronbunshu, 2020
Automobile repair options include three types: new, rebuilt, and reused parts. Both rebuilt and reused parts are manufactured from used parts, so environmental impact and cost are lower than new parts.

Analysis of vibration and acoustic signals for noncontact measurement of engine rotation speed [PDF]

, 2020
The non-contact measurement of engine speed can be realized by analyzing engine vibration frequency. However, the vibration signal is distorted by harmonics and noise in the measurement.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Carbon taxes, path dependency and directed technical change: evidence from the auto industry [PDF]

, 2012
Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between “dirty” (internal combustion engine) and “clean” (e.g.
