However, in some applications, such as a power generation facility, unwanted derating reduces the energy production which leads to lost revenue potential. Watch our video below to learn the causes of engine derating and how it affects engine performance. As the ambient temperature increases beyond designed operating conditions, engine derating begins, decreasing its efficiency. Deficiencies in a cooling system can result in higher engine fluid temperatures, which translates to a greater reduction in engine performance and an increase in fuel consumption. Although we cannot completely control engine derating due to high ambient temperatures, there are ways to mitigate some of the negative effects. AMOT has a range of temperature control products designed to maximize engine output and lower operating costs. Contact us to consult with an application engineer. What Causes Engine Derating?

Though hearty, the diesel engine is not impervious to occasional breakdown. This is especially true of late-model diesel engines , which come equipped with a host of government-mandated emissions equipment which can limit output when an issue is detected. If ignored, derate issues can leave truck drivers stranded. As mentioned, engine derate is a self-protective, or load limiting function that comes pre-programmed into the operating software of most modern diesel engines. This function first became prevalent during the earliest years of the new millennium, when more stringent diesel emissions standards were enacted by the federal government. When an engine enters derate, overall performance is significantly limited, as a means of self—protection. In this stifled state, an engine generally produces just enough power for its operator to exit the roadway, and seek further technical assistance wherever it is safe to do so. The exact extent to which a truck derates, or reduces power, varies by manufacturer. Certain engines, such as those bearing the Cummins or Paccar name, feature multiple states of derate, the first of which only limits power to a moderate level. This buys a motorist time to seek assistance and allows them to travel to the nearest truck-qualified truck shop.
