If you’re responsible for fleet performance, uptime, or emissions compliance, making smart idle policy decisions is critical. But with so much outdated and misunderstood information, it’s hard to know how idling truly impacts your aftertreatment systems.
This piece explains how DPF systems work, what they need to stay healthy, and why unmanaged idle, not idle, is often the real problem. Along the way, we’ll break down how APUs, factory auto-start systems, and Idle Smart each impact regeneration and downtime risk.
You’ll get:
- A clear understanding of how aftertreatment systems function
- The cost implications of different idle strategies
- What happens when engines don’t get warm enough to trigger passive regen
- Where factory auto-start systems fall short, and how smarter idle controls can close the gap
