Bimax Alchimia, boat “made in Lazio”

Redazione
Bimax alchimia

From the combination of a concept that is revolutionary in its own way and a turbodiesel renowned for its fuel efficiency comes an eight-and-a-half-meter walkaround capable of cruising at 20 knots while burning only one liter of diesel per nautical mile This boat is an eight-and-a-half-meter model from Bimax, a boatbuilder from Lazio known for the quality of its hulls, marketed under the name “Alchimia” and available in the “28” and “32” versions—designations that naturally refer to the overall length expressed in feet. The first is a 32-quintal walkaround characterized…

Honda Bf 115 marine engine: a four-cylinder for sea lovers

Redazione
honda bf 115

The Honda “BF 115” four-cylinder is part of a family of three engines built on a displacement of 2,354 cubic centimeters and delivering 115, 135, and 150 horsepower. The cylinders use a long-stroke configuration, with bore and stroke measuring 87 and 99 millimeters respectively, and they breathe through DOHC valvetrains with four valves per cylinder. On the “150” model, however, the valvetrain also incorporates the “VTEC” variable valve timing system, making the BF 150 mechanically quite different from both the BF 115 and the BF 135. The latter, in turn,…

Exports of battery materials and technologies: Pechino imposes new restrictions

Redazione

China has imposed new restrictions on the export of materials and technologies related to cathode production, the essential components used in electric vehicle (EV) batteries. This protectionist move—officially justified as a measure to ensure the “sustainable development” of the domestic battery industry—adds another layer of control over the global supply chain of strategic materials Years ago, Beijing had fully opened its doors to Western companies eager to manufacture locally. Over time, however, China has gradually distanced itself from these partnerships—absorbing foreign technologies, replicating production models, and building up the industrial…

Solid state batteries: what they are and how they work

Redazione
batterie allo stato solido

Solid state batteries represent a significant leap forward in electric vehicle technology. Unlike traditional lithium-ion batteries, which consist of a liquid electrolyte, solid-state batteries use a solid electrolyte, improving energy storage capacity and reducing charging times. Traditional lithium-ion cells contain four elements: anode, cathode, liquid electrolyte, and separator. Solid-state batteries simplify this design to just three elements: anode, cathode, and solid electrolyte, which acts as both an ionic conductor and separator Solid-state electrolytes can be polymeric, ceramic, or hybrid. Polymeric electrolytes enable ion transport through their molecular structure and can…

Come funziona una batteria al litio

Agricultural machines powered by electric motors powered by so-called “lithium batteries” are on the rise, components that can however be characterised by extremely different chemical compositions and therefore equally different performances. In these pages, a review of the most widespread types on the market, developed thanks to the collaboration with the online magazine “NewsAuto.it” Lithium Manganese Oxide (LiMn2O4) – Lmo The rise of electric-powered agricultural machinery has led to increased reliance on so-called “lithium batteries.” However, these batteries can feature vastly different chemical compositions, leading to significant performance variations. In this…

Sdf Farmotion 45 engine: designed for agriculture

Redazione

Ranked second in frequency of use among traditional tractors most registered in 2024 within categories “B,” “C,” and “D,” the Farmotion 45 engine—designed and manufactured by the SDF Group—powers the brand’s mid-range tractors. Holding a 12.5% share of the analyzed segment, this four-cylinder engine from the Treviglio-based group meets the needs of Same and Deutz-Fahr tractors, and together with the smaller Farmotion 35 engines, accounts for a total share of just under 17% Developed from the outset specifically for agricultural use, the Farmotion 45 features a four-cylinder inline layout with…

Automotive Hyundai, hydrogen on a dual path

Redazione

Despite the challenges linked to integrating hydrogen into automotive propulsion systems, Hyundai continues to refine both its fuel cell systems and hydrogen internal combustion engines. These two parallel lines of development combine technological innovation with real-world industrial applications Over recent years, hydrogen has taken on an increasingly central role as an alternative energy carrier, emerging as one of the most promising solutions for reducing emissions in the automotive sector and giving rise to two distinct yet complementary technological directions: on one hand, fuel cell propulsion, and on the other, the…

Transmission oils: new Sae standards come into force

Redazione

The Sae 300 standards, issued in 2021, introduced an update to the viscosity classification system for engine oils. This year, a similar update has been applied to SAE J306 standards, which regulate lubricants for transmission oils, axles, and differentials, aiming to support the development of higher-efficiency systems The acronym “Sae” stands for “Society of Automotive Engineers”, the international standards organization serving the aerospace, automotive, and vehicle industries. Among its various responsibilities is the definition of lubricant classification standards for these sectors, which are periodically updated as technological progress gives rise…
