Yes, there is a V12 engine. It's a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft.

In some forms of zircon. UV light causes the stone to change color. a process known as sunlight. Prolonged exposure to other factors. including heat. chemicals. and UV radiation. may cause permanent damage to the stone. It is best to minimize UV exposure in order to maintain the stone in good condition. but zircons that are free of impurities are usually more resistant to these effects.

Common-Rail Direct Injection (CDI) engines, developed by Mercedes-Benz, were primarily designed to enhance the efficiency and performance of diesel engines. The CDI technology focuses on improving fuel injection into the engine, making it more efficient and providing better combustion, which results in higher performance and lower emissions. While CDI technology itself is about the precision and control of fuel injection, many CDI engines are indeed equipped with turbochargers. The addition of a turbocharger complements the efficiency of CDI by forcing more air into the combustion chamber, which when combined with the precise fuel injection of CDI, significantly boosts engine power and efficiency. However, not all CDI engines come with a turbocharger as standard; it largely depends on the specific model and its intended performance objectives. In summary, while CDI technology primarily pertains to fuel injection, many CDI engines utilize turbocharging to further enhance their performance and efficiency.
