What is turbo engine ? – Turbocharged engine

Technology, Vehicles
A turbocharger, (or turbo), is a turbine-driven constrained acceptance gadget that expands an inner ignition motor's effectiveness and force yield by compelling additional air into the burning chamber. This improvement over a normally suctioned motor's capacity yield is because of the way that the blower can compel more air—and proportionately more fuel—into the ignition chamber than air pressure alone. In normally suctioned cylinder engines, admission gases are "pushed" into the motor by barometrical weight filling the volumetric void brought about by the descending stroke of the cylinder (which makes a low-pressure zone), like how fluid is drawn up into a syringe. The goal of a turbocharger is to improve a motor's productivity by expanding the thickness of the admission gas
