DPF delete done and dusted!๐. HINO DUTRO, BABY QUANTUM and NV350 came through with the following PAINS:
1๏ธโฃ๐ฆ๐ฒ๐๐ฒ๐ฟ๐ฒ ๐น๐ผ๐๐ ๐ผ๐ณ ๐ฝ๐ผ๐๐ฒ๐ฟ
-the engine was struggling to breathe due to excessive exhaust backpressure.
-turbo boost was limited,resulting in sluggish acceleration and poor torque output - especially NOTICEABLE on INCLINES or when LOADED.

-the Diesel Particulate Filter(DPF) continously ATTEMPTED FORCED REGENERATION(burning off soot), which overheats the exhaust system, and CONSEQUENTLY the engine itself.
-too frequent regeneration cycles shorten the lifespan of the turbocharger and the ENGINE itself.

-the DPF warning light and engine warning light were an eyesore to the customer,worsened by limp mode activation, the vehicle was under-performing BADLY.
4๏ธโฃ๐๐ป๐ฐ๐ฟ๐ฒ๐ฎ๐๐ฒ๐ฑ ๐ณ๐๐ฒ๐น ๐ฐ๐ผ๐ป๐๐๐บ๐ฝ๐๐ถ๐ผ๐ป
-the engine was now working HARDER to push exhaust gases through the CLOGGED DPF,burning more diesel than normal!
-extra diesel gets to be injected during regeneration,resulting in BAD FUEL ECONOMY.
5๏ธโฃ๐๐ป๐ด๐ถ๐ป๐ฒ ๐ผ๐ถ๐น ๐ฐ๐ผ๐ป๐๐ฎ๐บ๐ถ๐ป๐ฎ๐๐ถ๐ผ๐ป
-"post-injection" during "too much frequent" regeneration cycles caused diesel to wash down into the oil sump.
-this diluted engine oil,resulting in:
1)reduced engine lubrication.
2)increased wear on critical engine components like the crankshaft and bearings.
3)engine ceasure(knocking) kuti "ko ko ko ko, GO, zii, engine hapachina pelile๐"

-excessive exhaust backpressure and excessive HEAT could have led to turbo and engine damage if the DPF delete had been DELAYED.
-in extreme cases, cylinder pressures rise TOO HIGH,risking the following:
1)head gasket failure.
2)piston damage.
3)engine ceasure(knocking).

-replacing or PROFESSIONALLY cleaning the DPF is EXPENSIVE!
-a severely clogged DPF needs to be replaced by a BRAND NEW unit, costing thousands, THAT IS WHY IT IS LOGICAL JUST TO DELETE THE DPF!

1)idling.
2)short runs.
3)stop-start deliveries RESULTING in increased DPF problems as the engine doesn't get enough time and conditions to regenerate the DPF.
