In 2013, under the call of the National Energy Conservation and Emission Reduction, domestic internal combustion engine companies increased their production and sales in natural gas engines. As one of the earliest companies engaged in the development of gas-fueled engines in China, Weichai Group has been at the forefront of the development, production, and sales of natural gas engines. Driven by continuous upgrading of technology, quality and after-sales services, the Weichai Group continued to sell its gas engines. In 2013, Weichai Group's sales of gas engines reached 38,500 units, an increase of 75% year-on-year.
Weichai natural gas engine
Weichai Group started to research and develop natural gas engines since 1999. With the continuous development of the domestic natural gas vehicle market, the Weichai Group's gas engine products are gradually put on the market. The product models include WP5NG, WP6NG, WP7NG, WP10NG, WP12NG, WP13NG, etc. It covers 120-353 kW and meets national IV and national V emission standards. It is widely used in many industries such as city buses, road passenger cars, heavy trucks , construction machinery, ship power, and power generation equipment to meet the needs of our customers. Power requirements for light buses and trucks.
Weichai Group's natural gas engine adopts an internationally advanced electronically controlled single-point injection system. Due to its precise fuel control, it has the characteristics of fast response and good economy. In the national V emission stage, the Weichai Group natural gas products still use the lean-burn combustion and oxidation catalytic emission routes, which not only ensure the economic advantages of products, but also reduce the cost of customer emissions. For the characteristics of slow natural gas combustion and high heat load, The Chai Group has conducted special research and development on cooling systems, ignition systems and exhaust systems. In addition, Weichai Group has been paying attention to the verification and assessment of product optimization design, bench testing and vehicle testing to ensure and maintain the superior market competitiveness of natural gas products.
With advanced product technology and ultra-low energy consumption, Weichai Group's gas engines have gradually gained the trust of more and more customers. Many supporting host customers stated that the low gas consumption and timely service are the main reasons why they chose the Weichai LNG engine. According to calculations, according to a car running at least 100,000 kilometers a year to calculate, the current natural gas price is about 4.5 yuan / cubic meter, even if calculated according to the lowest value of 100 kilometers of solar terms, a car to save operating costs at least 60,000 yuan per year . Taking Shaanxi Auto Truck Co., Ltd. equipped with Weichai WP12 gas engine and a 29-ton truck load as an example, the field test results showed that the gas consumption per 100 km was only 34.93 kg, which was nearly 3 kg lower than that of competing products.
In addition to the high technological content and low energy consumption of gas, sound after-sales service is an important reason why Weichai Group's gas engines have won the recognition of customers. It is reported that at present, the matching market for gas engines of the Weichai Group has covered various fields such as trucks, buses, marine power generation, and construction machinery, and the market has increased rapidly.
