Recently, the FISITA2012 World Automotive Engineering Annual Conference and Exhibition sponsored by the China Association of Automotive Engineers and co-organized by Nuremberg Convention & Exhibition Services Co., Ltd. opened in the China National Convention Center. Weichai Power was invited to participate in the exhibition and exhibited two engine products: WP7 series diesel engine and WP12HPDI gas engine .
In this exhibition, Weichai Power highlighted WP7 series diesel engines and WP12HPDI gas engines. Among them, the green environment-friendly engine WP12HPDI gas engine is highly favored, and during the exhibition, visitors to the booth visited the consultation. The engine uses natural gas as the main fuel and uses a high-pressure common-rail direct-injection fuel system to inject 5% of diesel fuel into the cylinder before compression TDC, and 95% of natural gas is injected into the flame at 300 bar to become the main fuel. Combustion work, thereby achieving a 70% reduction in particulate matter emissions, carbon dioxide reduction of about 20%, to meet the national emission standards. The HPDI engine ensures the power, torque and efficiency of the original diesel engine. Its power is exactly the same as that of the diesel engine, and it brings a revolutionary technological innovation to the traditional spark plug ignition type natural gas engine. At the same time, high-pressure direct injection nozzles can further improve performance, reduce fuel consumption, emissions, and noise according to common rail injection engine design, saving fuel costs for users and creating greater economic benefits.
Founded in 1948, FISITA (Federation of International Automobile Engineering Societies) has developed for more than 60 years and now has 37 member states covering more than 170,000 professional engineers worldwide. It is known as the "United Nations" in the world of automotive engineering technology.
