“…The FTP-75 driving cycle was performed in 7 sources (A, B, C, D, I, J, K, and L), whereas the NEDC in 5 sources (E, F, G, H, and M). When it comes to differences in terms of relative changes of fuel consumption when using the same fuels but different driving cycles, A. Olmos et al [86] showed in the case of E22 and E100 that those relative differences of FC when comparing FTP-75 with NEDC are negligible. Therefore, FTP-75 and NEDC results could be compared to each other.…”

“…Therefore, an additional effort is required to reduce NMOG emissions. It is crucial to identify solutions to improve EHR fuel vaporization and combustion quality prior to engine warmup, avoiding misfires and poor combustion events occurrence [6], [7].…”

One of the main challenges for OEMs to reduce tailpipe emissions is to meet emissions regulation at minimum costs, keeping the vehicle at affordable price to the final customer. Starting in January 2022, all vehicles sold in Brazil will need to comply with PROCONVE L7 (PL7) emissions regulation. PL7 imposes more stringent emissions limits and new procedures to be followed such as the NMOG (Non-Methane Organic Gases) determination. This paper details the NMOG calculation with ozone formation potential corrections. The PL7 NMOG + NOx emissions limit is one of the biggest challenges when running tests with EHR fuel (reference hydrous ethanol) mainly due to aldehydes and unburned ethanol generation prior to engine warmup. The majority of NMOG is generated during the cold phase of ABNT NBR 6601 emissions cycle. This paper aims to detail potential actions to reduce NMOG and meet the PL7 emissions limit when running a light passenger vehicle with low displacement PFI (Port Fuel Injection), normally aspirated, three cylinders engine and fueled with EHR fuel. The emissions tests were run at Ford Tatuí Development Center.

Energy management and vehicle fuel economy are important automotive development drivers besides ambient emissions. Many technologies and solutions are being proposed, compared and improved. Any solution demands expensive resources to be tested and sometimes even the most accurate experimental arrangement is not enough to prove its effectiveness. In this scenario numerical simulation represents an important and reliable tool to make sure even very small improvements, very difficult to be measured, could be honestly compared. Considering that a vehicular solution could be more efficient depending on drive cycle this paper compares, by numerical simulations, the impact of vehicle powertrain plus driving conditions on a passenger car fuel economy. From powertrain side different transmissions, manual (5 and 6 speed) and automatic (6 speed: dual clutch, torque converter and CVT), are compared. From driving conditions side different test cycles (FTP75, HWY, NEDC and WLTC) and vehicle loads (unloaded 1000 kg vehicle and loaded 1500 kg vehicle) are compared.
