engine called 5 time

I would be interested in information from the so -called 5 -time engines, how little I know is that it is a three -cylinder engine that only work the cylinders of the tips and the exhaust goes to the third cylinder that compresses it and it must send it to the other two cylinders in addition to going with turbo to see if someone could indicate where I can get more information since I am a grandfather who still has passion for mechanics www.manualsdemecanica.com/components/co...Moticons/shocked.png
