Recently, SAIC-GM-Wuling reported that its total sales volume was 1.458 million last year, not only fulfilling its annual sales target of 1.35 million, but also increasing by 12% over the same period of last year.
According to Yuan Zhijun, Deputy General Manager of SAIC-GM-Wuling, SAIC-GM-Wulingâ€™s sales target for 2013 is set at 1.5 million units.
In the three major operations of SAIC-GM-Wuling, the commercial vehicle market continues to lead the market. The annual sales volume has now reached 1.348 million, ranking first in the mini vehicle market. On the passenger car side, Baojun's products have sold over 10,000 units a month and the cumulative sales volume has exceeded 110,000 units. In overseas operations, after the Wuling Hongguang production line was exported to India last year, the N300 (Wuling Rongguang) model of this year's subsidiary successfully went offline in Egypt.
The sales volume of specific models is as follows. Wuling Light sold 530,000 units this year and accumulated sales of 4 million units. Wuling Rongguang sold more than 490,000 vehicles this year and was the first domestic model to be produced in Egypt. Wuling Hongguang listed for only two years, accumulatively sold more than 300,000 vehicles. Baojun 630 stabilized at more than 6,000 monthly sales in the second half of the year.
The piston is one of the main moving parts of the
engine, is composed of combustion chamber components.
The pressure of the gas piston through the connecting rod to the crankshaft, realize the change from heat energy to mechanical energy.
The work condition is very bad, and the temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas contact, greatly alternating thermal stress and mechanical stress.
And by the serious corrosion of gas, and under the condition of boundary lubrication and cylinder wall friction and strong impact 1 times.
The piston in high temperature, high pressure, strong corrosive gas contact so that it has enough strength and hardness,
Heat resistance and good thermal resistance, high fatigue strength and corrosion resistance. For high speed Diesel Engine Piston also requires light as far as possible.
In order to reduce the inertia force.
Marine piston large low speed diesel engine of the crosshead is usually combined.
The heat treatment process by normalizing and annealing, and iron pearlite are ferrite organization, has good heat resistance.
Piston alloy quenched and tempered steel has better heat resistance and corrosion resistance. The skirt with nodular cast iron annealing treatment, with good wear resistance.
