Small V8 engine made from Lego works on compressed air It seems that if you have a good imagination you can make just about anything from Lego. We have seen some great ideas of what it is possible to make using the bricks and more recently we have come across a handmade small working V8 engine made entirely out of Lego bricks. This isn’t just something to look at, it really is a V8 pneumatic engine that works. Of course not everyone is going to be able to replicate a working V8 engine in Lego bricks as the person behind it must have a lot of mechanical knowledge, plus lots of spare time and dedication to put this together. The sound of this tiny working engine is great and it makes you wonder what we will see next. Maybe the car to go with the engine?

Official LEGO Comments 1 The 1970 Plymouth Barracuda is one of the most sought after muscle cars. Especially the rare convertibles optioned with a 426 HEMI V8, and a four speed transmission. That is exactly what this car is! The size of this car is 22 studs wide, and 54 studs long. Which makes this car to a large 1:11 scale. Everything opens: Shaker hood, doors, trunk, and even the glove box! The car also has a LEGO Technic V8 engine exactly detailed as a 426 HEMI, rear wheel drive, suspension at the rear, and working steering with the steering wheel. Here is a list of all the engine details:
-LEGO Technic V8 with crankshaft, rods, and pistons -Orange cylinder heads and intake manifold -The giant black Hemi valve covers -Breather hose and PCV hose -Spark plug wires and distributor -Radiator (only with the upper hose) -Belt driven fan, alternator, and crank pulley It's time for LEGO that they are going to make some real American muscle cars! So if you want a 1970 HEMI 'Cuda in LEGO in 1:11 scale, then please support so it can become a real LEGO set!) and Ivan (idic.at) have released their new LPE motors at LPEpower.Finally they are selling a V8 configuration, after adding 1 month ago, the 2nd version of their Inline 3 LPE. The new 3 cylinder engine (SYS I3) is more powerful, smaller and lighter than its 3 cylinder predecessor.Even it outperformed a V8 version back from 2005, which powered Alex's Ford Mustang at the time.The new SYS I3 main features are:The new crankshaft concept in combination with the Scotch Yoke principle of operation.
The first and last crank pieces are constructed from 36 toothed bevel gears and are interconnected with a very rigid longitudinal shaft that prevents the crankshaft from twisting, which in terms greatly improves the torque output. The new camless valvetrain. Sliding yokes directly move the valve rockers - there are no shafts, cams or pushrods in the new camless valvetrain, therefore a huge amount of torsional friction has been eliminated - the new SYS I3 has ONLY eight moving parts! (For comparison: a standard conrod inline 3 with pushrod valvetrain would have arround 17 moving parts) For a complete description, please refer to this LPE webpage, at LPEpower.This motor motor performs 1500 rpms at 4 bars (60 psi) and is selling for 130,00€.A much more reasonable price than their predecessors, despite still a significant amount of money. However we should look at it from a partcount perspective as each of these motors include some highly priced pneumatic cylinders in the actuality and should take a significant amount of working hours to assemble, test and fine tune.
Below some videos from LPEpower YouTube channel, where you may see SYS I3 in action, inclusive the respective Mustang driveby, Now the most witted and new LPEpower first version of a V8 engine (V8-1.0). This motor main highlights are:Compact size with only 15 studs of length, while eliminating the crank end-to-end twisting and engine vibration.No V8 ever run so smooth on such low rpms, while at the same time offering 1500 rpms on only 4 bars of pressure.Integrates a centrally positioned balance shaft that also acts as a timing distribution gear. It prevents the crank and camshaft from twisting and enables a very precise operation even under great stress.It uses only 4 valves in the engine, you might wonder why. It enables a more balanced distribution of air to the paired cylinders and drastically reduces a lot of friction. Both are the key for such a smooth operation and for high rpms in a V8. A proper valvetrain geometry must pass the central point of the valve in as few degrees of the camshaft revolution as possible in order to offer the maximum air flow.
During one camshaft revolution each valve spends only ~60° in its central dead point, on the other ~300° it offers full potential air flow to the cylinder.The total engine weight is only 410 grams. In LEGO terms that would equal to an aluminum block and heads of a real V8 engine.This engine is actually capable of a much greater speed than 1500 rpms, but it was timing finetuned for the smoothest operation on low rpms and the biggest torque output throughout the entire rev band.For a complete description, please also refer to this LPE webpage, at LPEpower.On the videos below, you may see this V8 in action. In standalone and inside the Alex's Mustang, The V8 sells for 390,00€.
