Direct water injection and combustion time in SI engines

Over time, internal combustion engines were profoundly developed becoming more reliable, more economical and less polluting. Even if the current trend is headed towards hybrid and electric vehicles, the development of these engines continues by optimizing its operation with alternative fuels and inn...

Even if the current trend is headed towards hybrid and electric vehicles, the development of these engines continues by optimizing its operation with alternative fuels and innovative technologies.
