What is up engine heads, today I have something really interesting for you, a brand new inline four cylinder engine that has the potential to completely change the game. Why? Because it claims that it has overcome the single greatest limiting factor of any inline four cylinder engine – and that is its displacement.

A few days ago I was researching and fact checking for one of my future videos and then I stumbled onto this page. This is the startup investor page for AlfaDan inc. Never heard of them? Neither have I. As you can see they’re looking for investors for their brand new marine outboard engine and have already raised more than a million dollars.
But that’s not what’s interesting. What’s interesting is that this is an inline four engine that aims to outdo V6 and V8 engines at everything. Now I’m not really familiar with the outboard powered boat industry but apparently the big deal is that these boats have grown over the years and by doing so they also need more power to push them through water. So the solution has simply been to add more outboard engines. Obviously this isn’t an optimal solution as it increases weight and fuel consumption.

And here’s where things get really crazy. ALFADAN claims that their revolutionary inline four engine offers 50% more horsepower, 50% less weight and 50% less moving parts compared to all current outboard engines. In other words 3 Alfadan inline fours can make the same power as 6 competitor engines at half the weight. I was like yeah right…..I’ve heard plenty of too good to be true claims over the years and that’s exactly what they usually are…too good to be true. So I decided to read on to see how exactly they claim to have achieved this. And here as you can see they talk about the inherent secondary imbalance we just spoke off, but more importantly they claim to have solved this design problem with a patented re-design of the i4 drive train, allowing ALFADAN to produce the very first high displacement inline four-cylinder engine.

So I kept scrolling down and things got pretty serious. This isn’t just empty claims, a proof of concept and feasibility study has already been completed. And not just by anyone, the feasibility study has been done my Mahle powertrain. As you may know Mahle is one of the most reputable names in the industry of engines and engine parts. The pistons inside the Bugatti Veyron are Mahle for example. I believe that says enough. Mahle has been at the forefront of engine downsizing, turbocharging and improvement efficiency.
But that’s not all. Alfadan has another big name behind them. Freevalve. You probably heard of them too. The sister company of Koenigsegg Automotive that has been making news headlines by developing a camless engine. That’s right. No camshafts which means no cam gears which means no timing chains or timing belts. The end result? A dramatically downsized engine with dramatically reduced friction and dramatically increased power potential.
