Wheel loaders are widely used in important engineering fields. The running state of the engine as its sole power source has a great influence on the economy of the loader. Aiming at the problem of highly transient fuel consumption of a certain type of wheel loader in China this paper proposes a control method for engine transient energy-saving control which reduces the instantaneous fuel consumption by limiting the angular acceleration of the engine when the accelerator pedal suddenly stamped. Aiming at the problem of poor fuel economy in V working condition and engine speed control without considering loader working condition recognition energy-saving control of the whole machine with two operating modes is proposed. The working mode was mainly set by mode selection switch. While realizing working condition recognition the operating points of the engine are distributed in the area with a low fuel consumption rate. The results of the field test show that under this control strategy the dynamic mode could make the whole machine have better dynamic property and fuel economy. In the economic mode the dynamic property is reduced but the economy is greatly improved.
