Which is the economy mode, E or P for trucks?

[Pires]

E stands for Economy mode, while P mode represents Power mode or Heavy-duty operation mode. P mode is primarily designed for high workload operations, whereas E mode balances both workload and fuel consumption. In P mode, both engine speed and pump flow rate are significantly higher, resulting in relatively greater fuel consumption. E mode reduces the main pump flow rate to some extent, aiming for lower fuel consumption, and is generally the preferred mode for routine operations. Additional Information: 1. P mode refers to Power mode or Heavy-duty operation mode, where both engine speed and pump flow rate are set high to prioritize heavy workloads, consequently leading to relatively higher fuel consumption. 2. E mode denotes Economy mode, which balances workload and fuel consumption, typically operating at 80%-90% power capacity. The main pump flow rate is partially reduced in this mode to achieve lower fuel consumption, making it the standard choice for general operations.
