Since Nikolaus August Otto invented the four -stroke engine with compressed load in 1876, its evolution has been constant to the present day.Many have tried to improve it by changing the design of their cameras, the entrance of gasoline or their own internal structure with different results.But today's case is a more nut rotation.It is an engine that does not need oil and only weighs 10 kilograms.
The inventor of this curious engine is an Israeli company called Aquarius Engines and has been working on this project since 2014, now reaching the last stage of its development.The Aquarius Two Sided Free Piston Linear Engine (FLE) as it has been called, it is a linear internal combustion hydrogen engine that uses opposite forces to generate movement through a "free piston" system, creating a hugeamount of power in a small space.In the beginning it will be used as an auxiliary engine of electric/hydrogen vehicles although brand engineers ensure that it can be used in vehicles alone.
It is created from 20 pieces
This small engine of just 10 kilograms has a unique operation that we will try to explain to be understood.The propeller itself has a piston mounted on a rigid axis that moves laterally.This movement is achieved thanks to the internal combustion generated in the two cameras that have the sides.

Two cameras that do not have valves since these have been replaced by two ports located on the piston axis itself.The injectors are placed each in a combustion chamber and are responsible for injecting the fuel at the precise moment.The best of all is that it does not need an oil lubrication since the set uses a graphite coating in the piston and the cylinder, which avoids the "parasite" burning of hydrocarbons, thus reducing pollutant emissions of the engine.

At first this engine was going to work in gasol.The propeller is only able to generate up to 100 hp of power with a single module, although if it joins as in a generator the power can be raised enough horses.But if something attracts attention is its construction since it only uses 20 pieces to form.
The absence of lubrication brings another advantage, and it is to make maintenance periods extended over time and are not very expensive.According to the company, the engine can work perfectly for 10.000 hours what the average use of a hybrid vehicle is taken as a reference, would be equivalent to 80 thousand kilometers.
Companies like Nokia have already signed up to use despite the fact that the final development remains in process.Once finished, the Israeli company expects its application to reach everyone, whether as an auxiliary generator, as a main engine or as a base.
Application possibilities are infinite even if we want something difficult for such a project to apply on a motorcycle.However, it has numerous advantages and above all a reduced weight that would benefit its implementation.Maybe a boxer -like assembly like the BMW use would be the most correct.Only time will tell us if this engine becomes the industrial revolution of the 21st century.
