Nowadays, the environmental-friendly products are becoming more and more popular in every walk of life and there is no exception for the auto industry. Thus, the energy saving performance parts—turbocharger is coming back. And what make that happen?
Modern turbochargers benefit from a stainless-steel housing (instead of cast iron) and improved nickel-alloy turbines, which gives them the ability to withstand up to 1922 degrees F, allowing the engines to run much closer to ideal stoichiometric air/fuel ratios.
Small tweaks introduced into the modern turbos include: better shape of the blades, bearings that run on less oil, and lighter materials, which enables the turbo to spin 18 percent faster at around 200,000 rpm with reduced weight. Besides, the then turbos were designed to produce the maximum power and were most efficient at high engine speeds. But now, thanks to the new design of the turbo, it can work efficiently when engines run at light load and medium speeds, thus, conserving more energy. It is safe to say that a small, modern, gasoline-turbo engine will save about 8 to 10 percent over a large engine that makes similar power and torque. Amazing, isn’t it?
Moreover, the technology advancement applied to the engine also helps turbochargers to regain its popularity. For instance, the two knock sensors employed by Ford’s Ecoboost V6 can instantly detect engine-killing detonation, thus advancing the ignition timing and at the same time ensuring the safety.
There is no doubt that the idea of energy conservation will dominate every aspect of our life. And turbochargers, as an efficient energy saving partner, will have a bright future.
