SINGAPORE - Port Fuel Injection (PFI) vehicles will need to be banded for particulate matter (PM) or fine soot under the Vehicular Emissions Scheme (VES) from July 1, 2018, the National Environment Agency (NEA) said in a statement on Tuesday (June 13).
Car dealers will have six months from the commencement of the scheme on Jan 1, 2018 - which gives rebates for low-pollutant vehicles and surcharges for high-pollutant ones - to submit their PM emissions readings.
PFI vehicles, where fuel is injected just before the engine's combustion chamber, are currently exempted from the need for PM testing. This is because PM emissions from PFI vehicles are deemed to be low under current European emission standards, NEA said.
However, NEA has relooked its treatment of PM banding under the VES for PFI vehicles after "feedback and analysis".

Submission of emissions data will from July 1, 2018, be required for PFI vehicles, just like all non-PFI vehicles, so the vehicles can be banded for PM under the VES.
PFI vehicles that do not have PM emissions submitted can still be imported into Singapore - provided they meet the Euro 6 emission standards - but they will be banded under the highest VES surcharge band, which imposes a surcharge of $20,000.
The VES incentivises the purchase of vehicles that perform better than Euro 6 emission standards by providing a rebate or imposing a surcharge.
VES bands are more stringent than the respective Euro 6 standards for Carbon Monoxide (CO), Nitrogen Oxides (NOx), Hydrocarbons (HC) and PM.
"In the absence of emissions test data, there is no certainty that the PM emissions of PFI vehicles can be deemed to be negligible for the purposes of banding for PM under the VES," said NEA.
