Diesel engines are suffering from emissions of NOx and PM. Some conventional mechanical injection engines (like small diesel - 3 wheelers and small cars/SCV) will go out of production in 2020 , when BS VI comes, as these engines can't afford costly CRDI + After treatment systems. (DOC+DPF+SCR). Nox is the mostt difficult to handle. Tractor engines and stationary DG sets will face the problem of meeting NOX post 2023 to meet stringent requirements. We are doing R&D on Pre- treatment Technologies (PTT) for reduction of NOx and PM and improving fuel economy ( PTA- pre treatment of intake air , PTE- pre-treatment of Exhaust gas Re-circulation ; and PTF- pre-treatment of fuel) PTA and PTF are also about using alternate fuels like Methanol/ethanol and bio-diesel etc. Concepts have been tried and tested for PTA and PTF and scale up is needed for commercialization. PTE is still in concept stage . We need resources to move forward.
