”A killer technology”
When the CraftEngine passed the 15 procent efficiency mark, project manager at AVL Björn Zachrisson turned on his stereo and popped open a bottle of champagne. The advanced test facility at AVL in Sweden turned into a temporary disco!
”Right then I knew we had found a killer technology,” he says.
- A killer technology?
”Yes, a machine that, with small adjustments, has the technical c
apacity to out perform most of the other known technologies in the field and will beat the competition,” he adds.
Björn Zachrisson, project manager and development engineer at AVL’s multinational test plant outside Stockholm, is extremely impressed with the CraftEngine’s benefits and convinced that it has a global commercial potential.
”I am convinced that the CraftEngine is going to be a success all over the world. I’m impressed by the depth of competence and creativity that inventor Harald Nes Rislå possesses and, not least, the spirit and ambitions of the whole Viking Development team.
- But isn’t this technology already well-known?
”It’s true that similar technologies have been used in larger systems, but never on a small scale like the Craftengine, and that's the secret,” Zachrisson says. ”The CraftEngine has the potential of meeting a huge demand in the market. It can be used on farms, office buildings, apartment complexes.. You name it! But the market will be significantly greater if Harald and his team develop an even smaller version, and I’m sure they’ll be able to achieve that. A CraftEngine with a capacity of 2-3 kW would be of great interest to today’s households.”
Zachrisson says there are still a few tests and measurements at high and low temperatures left for them to do. The settings on the machine must also be calibrated to achieve optimal performance. The single-cylinder prototype, which has been tested by IPU in Copenhagen, will, most likely, be sent to AVL’s test facility in Sweden.
”Our plan is to carry out additional tests to compare the single-cylinder version with the one that has two cylinders,” Zachrisson says. ”This is the only way for us to decide which version to put into commercial production.”
- When will you make that decision?
”I think we’ll be able to make that decision in the next one to two months,” he says.
Zachrisson says the CraftEngine project is one of the most exciting initiatives he has ever been involved in.
”I love global products, like this one” he says. ”A surgery bed I helped develop a few years ago for General Electric is currently being used in hospitals all over the world. The CraftEngine has the potential of becoming a global product, which is why we have been working so hard to make it work. I have spent additional 15 to 20 hours per week and most weekends during the past six months working on it. When people tell me to get a life, I reply: "I've got a job, that's my life."
- Drinking champagne at work?
”Sure, drinking champagne and listening to music,” Zachrisson says. ”As far as I know, it was the first time this has ever happened at our test factory, but if you experience something like this I believe it was entirely appropriate.”
