Some 1000 attendees are expected to arrive in Helsinki for the 28th CIMAC Congress. This international gathering of combustion engine manufacturers, suppliers, experts, and legislative representatives offers the opportunity to be updated and fully informed on the latest developments in a variety of combustion engine related topics. Wärtsilä is a main sponsor of the event.
The presentations and discussions will cover product developments in diesel, gas, and dual-fuel engines; fuel injection & gas admission; turbochargers & air/exhaust management; components & tribology; controls & automation; exhaust gas after-treatment; basic research & advanced engineering; systems integration, propulsion & optimisation; fuels, lubricants & fluid technologies; and users’ aspects on maintenance & monitoring for both marine and land-based applications.
Wärtsilä will be presenting more than 20 technical papers and will have a prominent display at the exhibition. The focus of Wärtsilä’s stand will be the Wärtsilä 31 engine, which has been recognised by Guinness World Records as being the world’s most efficient 4-stroke diesel engine. The company will also be sharing information on its latest technologies.
CIMAC is a worldwide association consisting of National Member Associations, National Member Groups and Corporate Members in 26 countries in America, Asia and Europe.
Jaakko Eskola's speech
Speech held at CIMAC Welcome reception, Helsinki City Hall, 6 June, 2016.
Ladies and gentlemen,
I'm thrilled about hosting this event and welcoming you all to Helsinki, and so are many others at Wärtsilä.
The internal combustion engine has been around for over one hundred years. Despite new technologies and innovations on the market, the engine has kept its popularity throughout these years. And still today, it remains as relevant as ever.
CIMAC was born out of the need to collaborate to mend the damage done during the Second World War and today, the need for collaboration is just as acutely present. This time around, we need to prepare for what is to come as we take on the challenges brought about by climate change, rapid urbanisation and digitalisation.
With these challenges also come immense opportunities. Globalisation along with digitalisation has turned our world into one big connected entity, alleviating poverty for millions of people, making it much easier for local producers to reach world markets and for any entrepreneur to reach scale.
There are over 50,000 rivers in China alone, of which 123,000 km are considered navigable waterways and 61,000km are classified. These rivers serve the vast nation as a kind of bloodline with goods and services, and are therefore crucial.
A large part of the technology used today to transport these goods is fairly worn. Think of the positive impact we can have on the global environment with modern engines: less nitrogen oxides, less smoke and particulates and radically less fuel consumption. During my years in Asia, I have felt the urgent need to curb pollution. It's our CIMAC community's obligation to our planet to take our responsibility seriously.
This type of sustainable development is also what CIMAC is driving. A working group, 19 Inland Waterway Vessels, led by Professor Feng Wang is an excellent example of what is needed to curb climate change in this respect.
We've seen viable options to the combustion engines during recent years, and big steps have been taken with new technologies, such as energy storage. People may ask themselves whether the internal combustion engine will be made redundant in the coming years. Are its days numbered? Can we go about our daily lives without the one engine that powers everything from our lawnmowers to giant-size container vessels?
I don't think so. How we use the combustion engine will evolve, but it will still maintain a central position in the years to come.
Over the last 35 years, single cycle engine efficiency has gone up from just above 35 to 50%. We have introduced gas as a fuel and the infrastructure to support it. Nitrogen oxides’ emissions have dropped by 80% for diesel and even more for gas. We have learned to measure particulates and introduced reduction measures to limit their impact on our health. The engine has moved from being a standalone unit to becoming an integrated part of a system on both land and sea.
This trend will continue. Looking at the areas that will be presented during this CIMAC congress, you can judge where engine development is heading. Total efficiency will be over 60%, in combined solutions. Emissions will drop a large part of the remaining 20%. We will have after-treatment integrated with engines.
Already today, we can use 30% hydrogen in Wärtsilä gas engines. In the future, this will be one key engine fuel.
The engine has earned its place in any ship or energy system. Engine automation & control system development will make that engine performance optimal at any load and with any application. Engines will be connected on shore and on sea remotely for safe & optimised operation. It’s reliable, it’s flexible & agile, it’s cost effective, it’s environmentally sound, it’s powerful. The work being done here, by you, is enabling this development.
So even though the world is changing rapidly, and there are new types of energy sources available, the combustion engine remains as relevant as ever.
High efficiency, the possibility to use different types of gaseous and liquid fuels, as well as a good fit with intermittent energy sources like solar and wind, have given the combustion engine even more extended potential as an energy converter.
Flexibility in engine design requires a variable valve mechanism, to allow fast load-taking capabilities and optimisation at more than one load point. It also requires an electronic fuel injection, better known as common rail. Within a few years, all makers will have to move into electronic fuel injection on both land and sea.
Regardless of the development in oil prices, saving energy is still a key issue. From an engine point of view, it has been proven that high pressures on boost injection are the way forward. This sets its requirement on the base frame to be rigid and reliable, and calls for further calculations and simulations on stress and strength. To be able to have the same BMEP for a gas engine as for a diesel engine, a closed loop, self-adjusting combustion control is needed.
As we heard earlier today in Robert Ollus' speech, an engineer loves a challenge. To my knowledge, we are still missing the variable compression ratio, on many occasions said to be the Holy Grail for an internal combustion engineer. Provide that, and this industry will have yet one great value to offer our customers.
The last time CIMAC gathered in Helsinki was in the year 1981. Today we live in a world we thought was science fiction back then. Looking back, the first steps towards the globalised and digitalised world we live in today were taken that year. It was the year the word 'internet' was first mentioned, and Microsoft software MS DOS was launched.
The mind boggles when we ask the question: where will we be 35 years from now? We know that the megatrends that define the world today will be very much present and will have grown in magnitude. Urbanisation and digitalisation will continue to evolve, and the need for energy will increase. Climate change will continue to cast a shadow on everything we do, and in every venture we undertake, we have to take into account the environmental implications.
We will face great challenges along the way, but the last 35 years have shown that the best innovations are born out of challenges. Innovations are best brewed in an open atmosphere, and the need for collaboration will be ever present. So we are looking forward to the next 35 years of collaboration under the CIMAC umbrella.
I hope you'll enjoy your stay and leave Helsinki with a lot of takeaways from latest technologies and new friends.
