Maruti Suzuki introduced its all-new DDiS 225 diesel motor successful 2019, lone to beryllium discontinued a twelvemonth later. When the BS6 emanation norms rolled retired successful 2020, India’s largest carmaker announced that it would signifier retired its diesel engines and connection a petrol-only line-up going forward.

This announcement came arsenic a surprise, arsenic it had lone been a twelvemonth since Maruti had started offering the DDiS 225 motor successful the Ciaz and Ertiga. It seems it wasn’t the BS6 regulations that killed disconnected this engine, but a plan flaw.

According to a media report, the plan of the DDiS 225 motor made it intolerable to upgrade it to BS6 standards. Besides a dual-mass flywheel, the cylinder caput featured an integrated exhaust manifold. This configuration resulted successful the overcooling of the exhaust gasses. By the clip the exhaust reached the Diesel Particulate Filter (DPF), it turned into a liquid form.

This, accompanied by the soot couldn’t walk done the DPF filter. Also, the regeneration process would scope 1,300 degrees C, damaging the DPF and Diesel Oxidation Catalyst (DOC).

Maruti did see switching backmost to a much accepted bolt-on exhaust manifold. However, diesel cars had gotten adjacent much costly by past owed to the stricter emanation norms.

So, Maruti couldn't warrant the re-engineering costs for that motor contempt diesel inactive playing for astir 20% of wide car sales? That seems a spot shortsighted to conscionable fto spell of that large a market, particularly by the marketplace person nary less. Can they root a diesel motor from Toyota successful the future? That would beryllium an absorbing prospect.

I americium really rather blessed to spot this station due to the fact that I utilized to person repeated problems with my Maruti Ciaz which had the 1.5L Diesel engine. The motor was rather refined and the powerfulness was besides rather bully but determination were repeated issues with the engine, chiefly the cheque motor airy coming connected and off. In a alternatively isolated incident, 1 time the car motor conscionable decided to springiness up and erstwhile taken to Maruti we ne'er truly got an reply to what the occupation was but they got the car up and moving quickly.

Luckily for maine this car was my authoritative conveyance provided by the authorities and I had a accidental to power this conveyance with the older gen Ciaz with the much trustworthy 1.3L Diesel that was successful the section garage, albeit that was an older utilized model. To beryllium rather frank, I ne'er truly noticed that overmuch of a quality successful betwixt the 2 engines and preferred the 1.3 arsenic it NEVER gave maine a azygous occupation successful the ~50,000 kms that we enactment connected it.
