　　2. The strong adaptability of electronic fuel injection in daily use. As a well-established manufacturing enterprise, Volvo has mature technology and does not have the common faults of other electronic fuel injection machines. Its stability strengthens the equipment's competitiveness in the industry.

　　3. Having a good reputation and high usage rate, Volvo is no less attractive than direct injection excavators when used in harsh environments or even on high altitudes. The maturity of parts eliminates the burden of expensive maintenance, making the machinery more attractive.
