1. It is an all-aluminum engine with the latest exquisite design, light weight, large compression ratio, compact appearance, strong power, low fuel consumption and extremely low working noise. Aluminum alloy die-casting cylinder is beneficial to environmental protection, reducing the weight of the whole vehicle and improving fuel economy;
2.473QB engine has a long stroke and better power performance at medium and low speeds. At 2400r/min, the torque can reach more than130n.m. From the external characteristic diagram, the peak torque can reach 140N? m；
3. The timing system adopts silent chain, with low noise and maintenance-free; The connecting rod adopts advanced expanding and breaking technology with high reliability; The intake manifold is made of plastic ester, which has small airflow resistance and good heat insulation performance; High compression ratio design improves combustion performance, improves thermal efficiency and reduces fuel consumption.
4.473QB has the characteristics of low speed and high torsion. As can be seen from the external characteristic curve, 473QB reaches the first torque peak 134N at 2800 rpm. m； 4G 15S reaches the first torque peak 124N.m at 3000 rpm, so the 473QB has the characteristics of low speed and high torque, and the vehicle equipped with 473QB accelerates faster.
5.473QB has low fuel consumption. Due to the lightweight design, the fuel consumption rate is reduced, and the weight of the whole vehicle is also reduced, which is more conducive to fuel saving.
