4. Basic concept for car fuel saving test : 4. 4. 车子节油测试基本概念

A). Proceed with the test under the same condition;
B). The fuel saving rate varies due to different car models, ages, speeds, conditions and road conditions.
C). The allowance is smaller at the same section of highway to or from at a speed of 100 Kin/hr.
D). The allowance is smaller on highway at a speed of 100 Km/hr. but do not set the speed.
E). In downtown, due to the traffic light and traffic jam, the allowance will be bigger, which is not recommended.
F). New car has less carbon accumulation and new mechanism, the fuel saving rate will be lower.
G). New car must use fuel saver to prevent carbon from accumulating, keep a smooth fuel loop, maintain mechanism normal operation, which not only may save maintenance cost, but also may delay the mechanism aging and extend the service life.

A. 应在同一条件的情况下进行测试。
B. 因车种、车龄、车速、车况、路况不同，节油率会有所差距。
C. 约100公里同路段高速公路【往】【返】误差较小。
D. 行驶高速公路以时速1百公里的车速误差小，但不可以定速。
E. 市区内测试因红绿灯、堵车等因素误差会大，不建议使用。
F. 新车因积碳少、机件新、节油率会稍低。
