POLLUTANTS EMISSION REDUCTION
SI - spark ignition engines (petrol, LPG)
Quasistoichiometric combustion - low air excess at idle and constant loads and engine speeds, but subunit at accelerations and decelerations
High concentration emissions at acceleration and deceleration and at high loads and speeds
Emissions SI: CO, HC, SO2, NOx, PM
CO, HC, SO2, Nox are reduced up to zero in idle and constant loads ( ITP ) tests and decreases by 20 - 70% in accelerations and high loads and speeds; AFR also balances at high loads. PM decreases by more than 50%
CI - (diesel)
High air excess 350% - 750%, or even higher at constant loads and speeds, but much lower at accelerations (high loads and engine speeds)
High concentration emissions at idle, acceleration and high loads and speeds
Emissions CI: CO, HC, NOx, PM, PAH*
PAH = polycyclic aromatic hydrocarbons
Particles with carbon content ( PM ) and volatile organic compounds (HC, VOC, PAH) are decomposed and useful oxidized, up to 90%. Reduce smoke to zero when discharged, including during accelerations.
Emissions of polluting gases and particles will be reduced as a result of use, reducing their ability to form and reform from the beginning of the combustion process to the discharge. The process of reducing the emission formation capacity starts from starting the engine, ie it acts even before the catalyst is sufficiently heated. The engine will heat up two times faster with . CO2 emissions will be reduced in proportion to the reduction in fuel consumption.
Optimizing combustion processes, implicitly, reducing the concentration of exhaust emissions, is directly dependent on the state of maintenance of the engine, from the air filter to the flue gas discharge (completely sealed and complete exhaust system), including the state of the combustion management systems (sensors, couplings, spark plugs, coils, etc.) system application cannot provide the expected effects on engines with significant deficiencies.
