For fleet managers and diesel truck operators, engine derate can be a frustrating and costly problem. It’s the unwelcome reduction in engine performance that can bring your operations to a grinding halt. When your engine’s power is diminished due to factors like overheating, low oil pressure, or emissions system malfunctions, it’s not just an inconvenience – it can impact your bottom line. That’s where the Jaltest diagnostic tool from Triad Diagnostic Solutions steps in as your trusted ally, helping you not only prevent engine derate but swiftly resolve it when it occurs. We offer a range of Jaltest Diagnostic tools including Diagnostics Tools for Commercial Trucks, Agricultural Equipment, Off-Highway Equipment, Material Handling Equipment, Commercial ADAS calibrations and more.

Understanding Engine Derate

Engine derate is like a self-defense mechanism for your heavy-duty diesel engine. When your engine’s electronic control module (ECM) senses a condition that could potentially harm your engine or its emissions system, it takes proactive steps to reduce power output. While it might be frustrating, it’s a crucial safety measure designed to protect your engine from severe damage and ensure compliance with emission standards.

Some common triggers for engine derate include:

  • Overheating: High temperatures can cause engine components to warp or fail. Engine derate reduces power to decrease heat production.
  • Low Oil Pressure: Inadequate oil pressure can lead to engine damage. Derate reduces the engine’s workload to minimize the risk.
  • Emissions System Faults: Problems with your exhaust after-treatment system, such as a malfunctioning diesel particulate filter (DPF), can trigger derate to avoid further emissions issues.
  • Excessive Exhaust Temperatures: Extremely high exhaust gas temperatures can damage the turbocharger or other components. Derate lowers exhaust temperatures to prevent damage.

The Power of Jaltest in Preventing Engine Derate

The key to managing engine derate effectively is early detection and resolution. This is where the Jaltest diagnostic tool shines. Here’s how it can help:
