Gearing Up for New GHG Emissions Regulations
The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) have adopted the first-ever GHG regulations for heavy duty engines and vehicles. These regulations are geared to improve fuel efficiency and cut carbon pollution. Implementation will begin in January 2017 for all US and Canadian manufacturers.
The program promotes a new generation of cleaner, more fuel efficient trucks. The final standards are expected to lower CO2 emissions by approximately 1.1 billion metric tons, save vehicle owners fuel costs of about $170 billion and reduce oil consumption by up to 2 billion barrels over the lifetime of the vehicles sold under the program.
The regulations have spurred changes to many engine options, including:
|MX-13 and MX-11||PX-7 and PX-9||ISX15|
|New engine ratings||New EGR cooler||Revised turbo|
|Fuel-efficient turbocharger & air compressor||Damper diameter increase||Revised EGR cooler|
|Single canister aftertreatment||Single canister aftertreatment||Revised crank breather|
|Variable speed oil pump & coolant pump||Naturally aspirated air compressor|
|Fuel module with pre-filter||New fuel pump/lines|
|New harness routing||Composite oil pan|
|Valve cover material (MX-13 only)||Single canister aftertreatment
