Which engine is better in Weichai and Cummins?

Cummins is quite good. Although the price is a little expensive, the comprehensive performance of each part is good. The good sales of these two machines in China is inseparable from the timeliness of service. If I remember correctly, both of them should have the requirement to arrive at the site within 24 hours. 55 points for service. Besides accessories, the price of Cummins accessories is notoriously expensive. In terms of accessories, Weichai wins completely. Cummins is quite delicate to use. The engine oil, filter element and routine maintenance must be operated on time and in accordance with the safety regulations, otherwise it will be easy to break down. In contrast, Weichai is more bold and unconstrained, with large torque and large reserve power. It is not afraid of failure. Cummins patented PT fuel system with unique overspeed protection device; Low pressure oil pipeline, few pipelines, low failure rate and high reliability; High pressure injection, full combustion. Equipped with fuel supply and return check valves, it is safe and reliable to use. Air intake system of Cummins diesel generator set: Cummins diesel generator is equipped with dry-type air filter and air resistance indicator, and uses exhaust gas turbocharger, with sufficient air intake and guaranteed performance. In the past, Weichai’s dominant position in the field of heavy truck engines did not depend on its leading technology, but mainly benefited from the market environment. During the golden decade of the rapid development of the heavy truck industry in the past, the heavy truck enterprises focused on rapidly seizing the market and had no time to take into account the engine and other key parts. However, as the heavy truck industry has entered a stable development period, the industry competition has intensified, and the product technology has been upgraded, heavy truck enterprises have started to lay out engine manufacturing in recent years.
