| Résumé : |
Growing demand for sustainable solutions is driving the need for nove) norms forcing car manufacturers to create more efficient and environmentally-friendly engines. This is a major driving force in the global trend of electrification in the automotive industry. However, as the transition to electric motors will take severa I years, car manufacturers still have to find solutions for combustion engines as well. Downsizing engines is now a popular method to reduce car weight and consumption. Higher temperatures that come with downsizing have resulted in new material requirements. |
