NEW 2027 Cummins Diesel Engine EMISSION REGULATIONS are WILD **Diesel Mechanic Explains**

I discuss the impending EPA 2027 Emission regulation update for diesel engines like the 6.7L cummins, 6.7L Ford power, the 6.6L duramax and all the heavy duty diesel engines. This is the biggest EPA emission updated in almost 20 years. there are 3 major changes, 50% reduction in diesel particulate matter, 82.5% reduction in NOx gases and 180% extension on emission component warranties.

I figured i would breifly explain the 4 major compoenets of an emission system, EGR, DOC, DPF and your SCR all play a factor in reducing the 3 main polutants of carbon monoxide, particulate matter and nox gases.

the first major change is the reduction of particulate matter by 50% bringing the total amount of 0.005 grams which is a pretty heavy reduction. bringing the diesel engine level well below the average passenger gas vehicle.

the next major change is a reduction of nox gases by 82.5% which I think will be the hardest for manufactures to hit. cummins is going to be installing a 48V electric heater to help keep the SCR hot and thus reduce more nox gas making the whole system more effecient. they willl also be intoducting a new dual chamber SCR system.

lastly and this is what really interested me was the mandatory warranty extensions. current most medium duty diesel trucks are setting at around 100,000 miles of standard coverage warranty but now manufactuers will be forced to give a 280,000 miles warranty on emission components which is a major jump.

this unfortunately and as cummins points out will heavily affect the cost of the engines, driving up the cost of purchase significantly.
