Florida Detroit Diesel Allison’s Post

Here's a brief report on the testing of our hybrid propulsion system for the eWave 9000 catamaran. The system consists of two fixed 6 kW electric motors, manufactured by ePropulsion, and an outboard Tohatsu 30 HP engine equipped with a rudder attachment. Only the combustion engine can be steered using a steering wheel. When using only the electric propulsion with the combustion engine turned off, the yacht maintains full maneuverability across all speed ranges. However, issues may arise during weak reverse thrust. Physics comes into play as the lack of water flow around the rudder makes steering difficult. In summary, we have succeeded in developing a simple and reliable hybrid propulsion system for our catamaran. On one hand, it provides the possibility of silent and environmentally friendly sailing for many hours using batteries, and on the other hand, it ensures 100% safety, practically unlimited range, and extra power thanks to the combustion engine. 🚤⚡️🌊🔋🌿 #HybridPropulsion #eWave9000 #SustainableSailing #GreenTechnology #BoatingLife#ElectricEngine

The race to develop premium standards for engine coolants is underway. ASTM’s engine coolants & related fluids committee (D15) is finding new ways to test engine coolants in electric vehicles and to help combat issues such as overheating and range anxiety https://lnkd.in/eWHquuk7 #engines #coolants #EVs #electric #electricvehicles

The highs & lows of the rotary engine https://lnkd.in/esd77VRS For the last 130 years, almost every internal combustion engine fitted to a car has had anything from one to 16 pistons inside it. But this isn’t the only option. Some manufacturers have used, or at least experimented with, rotary engines, which at first sight appear to have a much more clever design. The fact that they have not become universal, despite having been available to the public for nearly 60 years, shows that this isn’t entirely the case. Nevertheless, they are fascinating devices, and well worth a look. We’ll start with a brief investigation of their history and design, and then discuss 36 actual or planned rotary-engined cars, in approximate order (because the timescale isn’t always obvious) of when they appeared:

Volvo Penta has expanded its D8 IMO III solutions for smaller, high-speed commercial vessels, including models like the D8 IPS-600, D8 IPS-650, D8 IPS-700, D8 450 hp, D8 510 hp, and D8 550. These 7.7-liter, 6-cylinder diesel engines deliver up to 405 kW and 550 hp, with common-rail fuel injection and twin-entry turbo with charge air cooling. Key to this range is Selective Catalytic Reduction (SCR) technology, which combines exhaust gases with diesel exhaust and urea through an integrated injector pipe. The SCR unit, featuring a rotating outlet, ensures compliance with emissions standards. Ideal for 15-meter commercial vessels like pilot boats and high-speed ferries, these engines operate efficiently at 20 to 40 knots. #volvopenta #dieselengine #commonrailfuelinjection #twinentryturbo #chargeaircooling #highspeedferries #selectivecatalyticreduction #emissionsolutions #imo

Transitioning from an internal combustion engine (ICE) to a #HybridElectric vehicle (HEV) can be daunting. Where do you start? Read our blog: https://prker.co/43jO9SA #Transportation #ACTExpo

Why has the United States and European Union imposed Tier 5/Stage V Engine regulations on non-road mobile machinery? One of the main reasons are related to reducing harmful emissions, technological advancements in fuel consumption and operational costs, health and environmental benefits. The intention is a pro-active approach to address air quality and reduce emissions produced from internal combustion engines. What we found when testing our new Tier 5 TwisterTrac VS350 is that during testing there was no soot visible in the exhaust pipe. The engine was also noticeably quieter and noise levels were less. How do you feel about the advent of Tier 5/Stage V engines and is this an initiative you support? #TwisterTrac #Innovation #CrushingPower #EasyMaintenance #ProudlySouthAfrican

The SU7 will eventually have three electric-motor options, with names taken from internal-combustion engines. Available first are the V6 option, rated at 295 horsepower, and the V6s, rated at 664 horsepower

We are permanently continuing work on the railway drone I mentioned earlier (https://lnkd.in/eyjn7CeQ). It’s important not only to make the transport move but also to brake, especially when it weighs a quarter of a ton. As is known, braking on electric locomotives is done by short-circuiting the windings of the traction motors. This same principle has been implemented in our design. https://lnkd.in/eBwuYxqY

The SAE J1939 standard (Serial Control and Communications Heavy Duty Vehicle Network) has originally been designed by SAE International to be used in heavy duty vehicles. In the meantime, the protocol is widely used also in agricultural machinery, rail vehicles and sea vessels and in a wide range of diesel-driven machinery. MicroControl J1939 protocol stacks (as well as our CANopen and CANopen FD stacks) facilitate effective software development. 👉 Our modular system shortens and simplifies your development and helps defining interfaces. 👉 The customizable software components based on standard elements sustainably increase transparency and effectiveness. 👉 Valuable working time is saved, and development and production processes are accelerated. #J1939 #MicroControl #heavyduty #agriculture #offroad
