It is a system that already has both Italian and international patents. The official press release explains that “it is a mechanical and forced control of the valves, both opening and closing. Once the structural and material resistance tests have been completed, we’ll move on to laboratory tests and then the engines will be installed in a company model for the appropriate road tests. An ambitious project that will represent a fundamental step in the development of products and the growth of the iconic artisan company founded in 1987.
Umberto Borile’s statements to Moto.it reveal all the details.
‘It took a gentleman from Spoleto, Dr. Massimo Fracassi, who is a well-known business consultant, to start over. The new company was born, it’s called Marik (from the first letters of his wife Maura and my son Riccardo, who we lost) and it will produce and market Borile motorcycles. The prototypes will always be made here in Vo’. We are now working on the engine dummy to present at MBE’
‘This is a new distribution system for four-stroke engines, designed, manufactured and patented by Borile. Basically, a mechanical and forced control of the valves, both when opening and closing. This system guarantees lower consumption and greater performance due to its lightness and smoothness. All you have to do is remove the spark plug and run it with your hands. It’s more compact than any other system: our cylinder head measures around 7 centimeters less in height than any other head with the same displacement. There are no springs, oscillators or chains, no sliding friction, no sliding of two surfaces. Here, the camshafts press on a ball bearing, which in turn is connected to a titanium rod, which raises and lowers two bars that carry the valves’.
The advantages are many, says Umberto Borile.
‘Other systems are based on a chain, which carries the movement from the crankshaft to the camshaft at the top end of the cylinder head. Now, sliding friction is created between the joints and links of this chain, even the skidder that stretches it creates sliding friction, even the camshafts in desmo systems slide on the oscillator. And all this sliding requires a lot of oil to reduce the possibility of seizure and to dissipate heat. Our system can also work without oil, which is an absolute novelty: only the lower part with the gears needs lubrication, but the lower part is affected by much less heat, also extending the life of the oil. And once again, all the rotating parts are in a low position, reducing the gyroscopic effect. These are all little things that together create a system that is both very simple and very effective. No valve adjustments and just a little oil vapor in the cylinder head’.
