Diesel Engine Reliability in Extreme Cold: Preventing Automatic Shutdowns.
This law enhances the safety and reliability of diesel vehicles and equipment in regions experiencing extreme cold temperatures. It allows manufacturers to temporarily suspend automatic engine power reduction or shutdown functions triggered by emissions control system faults when temperatures drop below freezing. This measure aims to prevent the immobilization of vehicles critical for safety and transportation in remote, cold areas.
Key points
Safety in Freezing Conditions: Below 0°C (32°F), manufacturers can temporarily disable automatic engine shutdown or power reduction features linked to emissions faults to prevent life-threatening situations or loss of essential transportation.
DEF Exemption: Vehicles operating in regions with prolonged freezing conditions (e.g., far north) can receive a year-round exemption from the requirement to use Diesel Exhaust Fluid (DEF), which often freezes and becomes impractical in extreme cold.
Ensuring Critical Mobility: The changes aim to ensure continuous operation of emergency and transportation vehicles vital for remote areas where engine failure poses a serious safety risk.
