Propulsion

The most significant developments in propulsion in the automotive, marine, aviation and rail sectors are driven by changes in emission legislation related to CO2 reduction, noxious emissions reduction and taxation policy. A global shift is taking place as consumers and governments demand a reduction in Greenhouse Gas Emissions across all sectors. It’s crucial for all sectors to develop sustainable propulsion systems and fuel options, and this is likely to result in a diverse propulsion system mix. Propulsion system development also needs to align with the infrastructure required to supply the necessary energy in various forms. A subscription to RiCK™ can help you discover trusted propulsion market research and intelligence for the automotive, marine, rail and aerospace industries. RiCK™ includes over 300,000 references, including 100 journal and magazine subscriptions, conference papers and reports, news and articles from organisations such as SAE International (Society of Automotive Engineers) and IMechE (The Institute of Mechanical Engineers.)

What is propulsion?

Propulsion is the driving force of an object; for road vehicles, the propulsion system drives wheels that produce traction through a reaction against a road surface, and for rail locomotives, it’s a similar process. Propellers draw in and accelerate a fluid stream to propel ships and aircraft.

What are the key developments in propulsion?

Hybrid and Electric Powertrains
One of the most significant recent developments has been the electrification of powertrains, whether this is the development of electric vehicles themselves or the production of dedicated hybrid engines (DHEs) which take full advantage of being part of hybrid powertrains. The powertrain industry is evolving rapidly and has seen powerful technology innovations, intensifying competition and increased regulation. Component suppliers help the rail, marine and automotive sectors meet demand by providing expertise in transmissions and power electronics to produce optimised components and systems. Numerous initiatives have given rise to studies and analysis of low or zero environmental impact powertrains. Key technological developments include the downsizing and boosting of engines, the application of variable systems such as variable valve-timing and variable valve-lift, and the reduction of mechanical friction.

Sustainable fuels and Biofuels
There are many competing sustainable propulsion system and fuel options being developed and all will have a role to play within the diverse propulsion system mix. Sustainable fuels including hydrogen, biofuels and synthetic electro-fuels (or e-fuels) can work in different sectors. For some sectors electrification is difficult and sustainable de-fossilised fuels are essential. Heavy-duty transport is likely to use hydrogen as a zero carbon fuel with propulsion via ICE or fuel cell electric systems. RiCK™ can be used to locate the latest research in this area.

Lifecycle emission reduction
In addition to existing legislation there is an increasing focus on GHG reduction on a lifecycle basis and increasing propulsion system efficiency. Accounting on a lifecycle basis will include energy production (well to wheels) and vehicle production and recycling. This will see an increased focus on technology and process improvement throughout the supply chain.

Sustainable Fuels and Biofuels
Sustainable fuels are now also being seriously developed, from hydrogen to biofuels to synthetic electro-fuels (or e-fuels), which can address the existing vehicle fleet as well as new vehicles. For some sectors like heavy-duty transport and commercial aviation, electrification is difficult, and the sector is looking to use sustainable de-fossilised fuels Heavy-duty transport is focussed on Hydrogen as the only suitable zero carbon fuel with propulsion via ICE or fuel cell electric systems.
