Zero-emission mobility is focused on solving the challenge of autonomy, which raises most of the doubts among those who are thinking of buying EVs. The truth is that there are other manufacturers who have chosen to develop new fuels (and some of them you have already seen). Today we are going to introduce you to a prototype that has gone even further: this is the first 1-stroke REx engine.
This is the enigmatic REx engine that has experts on edge: attention to this
The e-Rex engine from Innengine is a new 1-stroke engine design that is going to change the auto industry itself. The e-Rex engine performs all 4 strokes of a conventional engine in a single stroke. This is accomplished by means of a piston that is triangular-shaped.
It presses the air-fuel mixture on one side while the other side is moved by the combustion. The experts are amazed at how the 1-stroke idea makes the engine operating so simple and at the same time improves its performance.
Through the integration of the four strokes into one unbroken motion, the e-Rex engine delivers the power which is not only smooth but also seamless unlike anything that has ever been seen at this time. This can be the main reason for the enhanced driving experience and the ultimate perfection in driving.
The e-Rex is a significant milestone for the development of engine technology. Its design is so simple and elegant and at the same time the benefits over the traditional engines make it one of the most innovative in the recent automotive history.
Why it’s not just an electric motor like other ones? The key is REx
The e-Rex engine style has many significant advantages over the engines with multiple pistons and strokes per cycle. The main benefit is that it has a great number of stationary parts. A regular four-stroke engine needs two revolutions of the crankshaft to finish one cycle.
This refers to various pistons moving up and down, intake and exhaust valves opening and closing, spark plugs firing, and the rest of it. Numerous components are moving and they need to be timed and synchronized perfectly. The e-Rex has a single piston that works once in each cycle.
Thus, the efficiency of the operation is considerably improved and the number of moving parts is significantly decreased. So, as it turns out, the fewer components that are susceptible to wear and tear or failure, the more reliable the device is.
The unique rotary valve styling does away with the necessity of the traditional poppet valves that are often deficient in the ordinary engines. The e-Rex’s valve is as simple as a spinning disc with openings that fit with the ports in the cylinder head of the stationary head.
An increased efficiency to boost electricity in cars: godbye to hydrogen
The e-Rex engine proves to be a great example of fuel efficiency as it is far more efficient than the conventional engines. The e-Rex, which merges the intake, compression, power and exhaust strokes into one smooth movement, cuts out the inefficient pauses between cycles.
This optimization enables the engine to get more fuel energy which in turn gives the fuel economy gains of 15-30% over the standard engines. E-Rex is the ultimate in performance, efficiency and reliability and this is achieved by the use of the latest advancements in technology like variable valve timing and a starter-generator.
These improvements enable the engine to work at its best point even when the weather, road, or another factor is not favorable. Generally, the engines that use the old technology are wasteful of fuel when they start up, idle and accelerate because they have the fixed valve timing.
At this point, you may wonder: why is it important that a 1-stroke REx engine exists? Many might think it is simply a step backwards, but we believe it is a clear advance. Not only because it opens the door to fuel cell hybrid powertrains (similar to EVs), but also because it offers a short-term solution to decarbonization. The company expects to commercialize it on a large scale over the next few years.
