In the continuous pursuit of innovation, Japanese automobile giant Nissan has a patent for one internal combustion engine logged in, mostly off carbon fiber, also known as Carbon, is manufactured. An extremely interesting development that has the potential to change the rules of the game. The main feature of the construction is this Motor housing, which is made of lightweight yet incredibly strong carbon fiber, while the internal, highly stressed parts are still made of metal. But how does Nissan deal with the extreme heat loads that occur during combustion? Simply, they have provided a cavity between the metallic cylinder and the carbon fiber casing in which to continuously coolant circulates. The design is inspired by the principle of "wet liners". The use of carbon compensates for the weakened structural integrity, a known disadvantage of the principle, while reducing engine warm-up time, resulting in less wear.

At the same time, Nissan has also taken precautions to ensure that carbon housing not overheated. Although carbon has many positive qualities, heat resistance is not its forte. But don't worry, the engineers at Nissan have this covered! One of the main advantages of innovation is that it is clear weight loss of the motor. Carbon fiber composites can be up to five times lighter than comparable steel structures. Furthermore, they are significant stiffer and you coefficient of thermal expansion is much lower than most metals. The big question, in which vehicle does Nissan want to use the revolutionary carbon engine? Rumors point to the new one GT-R but we should not forget that a patent does not necessarily mean immediate mass production.
Conclusion
- Nissan is perhaps making an impressive step into the future of the internal combustion engine. By using carbon in the motor housing, you can develop a motor that is significantly lighter and heats up faster. With this, Nissan shows that there is still a lot of potential for innovation when it comes to combustion engines and that it will hopefully continue. Whether for sports cars or hybrid vehicles, lighter engines could make a significant difference weight loss mean and thus improve performance.
Of course, that wasn't the end of it!
