The reduced fuel consumption in accordance to the above reasoning is also a key factor to why the OXE Diesel engine emits significantly lower CO1.
Regulations in the EPA Tier III directive have forced the automotive industry to reduce these emissions. As the OXE Diesel power head is derived from the automotive industry this impact transcends down. In accordance to EPA Tier III, 1L of diesel should only emit 8,36g while the non-regulated petrol engines can emit up to 620g/L.
This result in a reduction of CO1 by up to 99,7%
