Low-emission Engines for Future Hybrids

Posted in Future Technology | Hybrid Cars | Transportation

Future Hybrids China is one of the most polluted countries in the world. But they are not unaware of the ill effects of the excessive use of fossil fuels. They are paying attention to lessening the environmental effects of the poisonous gases. China is making rapid strides towards clean energy and investing considerable time and talent in new researches regarding green energy. They are working on a new type of internal combustion engine. Researchers in China are developing and using a new and more accurate computer model to assess performance of the free-piston linear alternator (FPLA).


This research regarding the FPLA, can lead to a low-emission, fuel efficient engine for future hybrid electric vehicles. Qingfeng Li and colleagues point out that the FPLA has only one moving part and its engine is such that it can generate electricity.

In the device, a piston in a cylinder shuttles between two combustion chambers. Permanent magnets are attached on the piston to generate electricity by passing through the coils of an alternator centered on the cylinder. The advantage of this particular engine is, it can work using various fuels. The engine can burn a variety of fuels, including natural gas and hydrogen. This type of engine can be advantageous in a future world of climate change and possible fossil fuel shortages.

Here the research team is depending heavily on a computer model. Their report explains development of a superior computer model to appraise performance of the FPLA and direct engineers in creation of the engine. Results of their preliminary simulations showed that the FPLA could speed up three times faster than other internal combustion engines. This will burn fuel in ways that diminish air pollution. “It is an environmentally friendly power source for the future,” the report concludes.
