First, the popularity of manufacturers. The manufacturing accuracy and performance of diesel engines are directly proportional to the scale and investment of manufacturers. Only large-scale manufacturers have the strength to invest in high-tech processing equipment, thus ensuring the manufacturing accuracy and performance of products. Ask the farmers around to see whose diesel engine is famous. Fame also means that this diesel engine is recognized by everyone.
Second, the advanced nature and applicability of product technology. Advanced and applicable diesel engines are generally jointly developed with international leading enterprises, and are special diesel engines developed for supporting the application field of main engines. When they are researching and developing, they reflect the contemporary advanced level, and at the same time, they constantly improve their products and keep pace with the international modern advanced technology. However, the products of some enterprises, especially the small factories around large enterprises, are copied by surveying and mapping the products of large enterprises, or agricultural machinery is modified by changing the parameters of diesel engines supporting other industries. No matter mapping or modification, these enterprises can't learn the inherent technology of special products for large enterprises. Moreover, the special products of large enterprises are generally multi-series and multi-variety, and different products are matched with hosts with different power segments, which has a wide power range.
Third, the product's power, economy and environmental adaptability. Tractors, harvesters and other large-scale agricultural machinery products have a bad working environment, and often encounter gully obstacles, large and small resistance and other phenomena. Products with good power are easy to overcome because of their high power and torque reserve rate, keep the speed stable and ensure the working quality. For the economy of diesel engines, we should not only look at the fuel consumption when running, but also see whether the fuel consumption is greater and the power is stronger than other diesel engines when running. Agricultural machinery is bought and used, which saves fuel and runs fast. If it is hot in summer and cold in winter, it is a good diesel engine.
Fourth, the timeliness of service and spare parts supply. Busy farming time waits for no one. Harvesters and tractors work in the fields for a short time in a year. When they are used continuously with high intensity day and night, problems are inevitable. The key is the busy farming season, the services of manufacturers should be in place in time, and the accessories can be bought locally.
