CO2 emission reduction through mass and friction reduction in the components of an OTTO cycle flexible engine

The present article shows the effect of the mass and friction reduction inside the engine over the carbonic gas emission reduction in the atmosphere. Authors have confirmed that the mass reduction and low friction in the internal components of the OTTO cycle engine, achieved by exhaust and admission valves re-dimensioning and sealer's substitution can help to reduce fuel consumption and, consequently, CO2, the main greenhouse effect gas. It is exposed and discussed different measurements of torque and power curves, friction power, and specific fuel consumption compared in the same engine without the proposed improving actions.
