Abstract: "fuel remap" refers to economy remap, which is a process that adjusts a vehicle's Engine Control Unit (ECU) to improve fuel efficiency, to reduce the emissions or to increase the power. Regardless of the fuel remap ultimate goal, this process leads to the engine emission change. The current paper proposed a measurement system for a gasoline engine pollution detection during the remap process. The nitrogen oxides, carbon oxide and the hydrocarbons levels are monitored and also the particulate matters (PM) according to the Euro 7 standard requirements. The external temperature and pressure are measured and compared with the gas exhaust temperature and relative humidity to clarify all combustion processes. The accomplished test with the fuel remap process shows significant increase of the pollution levels of the detected gases and the ultrafine particulate matters with size up to 1µm.
