New Engines

Fascinating internal combustion engines in the past, and you can check out those videos via the links in the description later. Today, however, we're going to talk about three free piston internal combustion engines that could revolutionize the industry. Let's dive in. Many contemporary advancements internal combustion engines aim to reduce their size and weight, facilitating their integration into hybrid ve A new development from the Center for Energy Research showcases a free piston engine that serves as a generator in a hybrid car, providing electric power to both the battery and the electric motors. Structurally, the engine consists of two oppositely located cylinders housing two interconnected pistons. Between these pistons, a linear motor generator is situated. T It serves as a starter initially and, once the engine is running, it generates electricity. The declared efficiency of the increased efficiency is largely thanks to the removal of unnecessary components. For instance, there's no crank connecting rod mechanism in t Lateral friction, a common issue in standard piston engines due to the connecting rod angle, is also reduced. The absence of bearing supports allows the engine to operate at a Furthermore, tests have shown a reduction in harmful emissions by 15%. The end result is an engine that'significantly more efficient, cheaper to manufacture, compact, and easy to maintain. The operating principles are similar to those of conventional engines, meaning that massive funding for research is not required. Plus, the piston's position can be adjusted, thus varying the compression ratio, w The cooling system can also be downsized due to lower heat generation. The presented Mark V prototype includes four pistons with a total vol Essentially, it is two free piston engines working in opposition to each other to compensate for vibrations. T Based on visualization, it operates on a two-stroke cycle. A unified cooling circuit is used for both motors and the system. At the top, we have an intake manifold, with the exhaust situated at the bottom. The prototype itself is rather compact, just 50 centimeters long, 20 centimeters Many car manufacturers are also seeking solutions for maximally efficient internal combustion engines. This is why a major car manufacturer The goal is similar to create a compact generator for a hybrid ve T Let's first look at the structure. On the left, we have the combustion chamber, and a coil is located in the cylinder wall. Here, a permanent magnet is positioned on the piston. When these components move, energy is generated. The W-shaped piston structure, depicted in brown on the diagram, is designed to compactly accommodate all these elements. At the back of the piston, there are two gas spring chambers. T Now, let's consider the operating principle. There are two strokes. First, we see the power stroke energy is generated. Then, at the bottom dead center, the intake hole and the exhaust valve open. At t After the power stroke, the piston must be returned and the air compressed. For t During the power stroke, the gas is compressed. Afterwards, the piston returns and compresses the fuel-air mixture. Toyota conducted tests and the engine operated for several hours without issues, with a fairly The plan is to use two such interconnected engines in hybrid cars, w As we know, Toyota won't widely show off new technology until they've thoroughly tested it, so we'll wait and see. Now let's continue, but please, There's a t Structurally, this engine has a minimal n A hollow rod runs through the entire engine, where the piston, w There's also the engine block, and on the sides are two cylinder heads and two bearings. The intake holes are located wit Meanw As a result, we get minimal friction, a minim A weight 6 times less than a comparable traditional engine, and a power output of 30 kW for such a compact generator. One of these stationary generators has now been launched, and they will begin to be used in cars in a couple of years. Please write in the comments what you t
