Xichai's "Three Aces" Power Debuts at Construction Machinery Showcase Highlights Must Not Be Missed

On September 20, 2017, the 14th China (Beijing) International Construction Machinery, Building Materials Machinery and Mining Machinery Exhibition and Technology Exchange Conference (BICES 2017) was opened at the Beijing New International Exhibition Center. As the “big brother” of the domestic diesel engine industry, Xichai brought five advanced products that meet current emissions requirements, covering its three classic engine series: Aowei, Hengwei and Conway.

Xichai's "Three Ace" series debut

In this exhibition, Xichai brought its three series of products. The first is 2 Conway 4DW series diesel engines. The first model is the 4DW93-45DT4 engine. This engine adopts the electronically-controlled common rail +cEGR+CCV+DOC+PF technology route. The key components adopt international brand names with excellent performance and reliable emissions. It is the first multi-cylinder diesel engine in China to pass the US EPA Tier 4Final test; the materials used for manufacturing are environmentally friendly, free of harmful substances, and meet the EU ROHS directive.

The second Conway product is the 4DW91 series engine. It adopts Bosch high-pressure common rail technology, and the air intake method is naturally aspirated. No post-treatment system is required to achieve non-road four-phase discharge, and the whole machine has better reliability and lower cost. In addition, 4DW91 series smoke starting less than 1m-1, smoke less than 0.5m-1, in line with environmental regulations in Beijing, Shanghai and other places.

Followed by 2 Hengwei series diesel engines. One is Hengwei 6DF3 series diesel engine, which uses professional matching software to customize the engine performance according to the characteristics of loader operation, low torque, torque reserve coefficient up to 30%, and strong engine power. Hengwei 6DF3 series has a unique high-power soft starter's motivation to effectively reduce the starter's failure rate, good low temperature start-up performance.

The other is Hengwei 4DLD series diesel engine. In the domestic diesel engine, it has taken the lead in adopting electronically controlled variable cross-section supercharging technology. At the same time, it adopts the hot-end EGR valve, which greatly improves the transient response of the diesel engine, and the overall machine economy and reliability are better. In addition, this engine uses four-valve technology, combustion is more complete, the entire machine than the equivalent fuel economy 5% -8%.

The last one is the Xichai Aowei 6DL2 diesel engine. Its displacement is 9L, power coverage is 220-300 hp, and industry leader in anti-mutation load capacity. The 6DL2 series engine adopts four valves, supercharged air cooling, mid-end high-end electronic control unit pump and electronically controlled common rail. It has reached the third stage of non-road and has the ability to meet the fourth stage emission standard. .

The unique advantages of Xichai help the market

The five models of Xichai engines that were exhibited at this time, despite different technical routes and emission standards, share several common features.

First of all, strong power, strong environmental adaptability, and high work efficiency. These engines use electronically controlled single-unit pump fuel systems, which are fully burned, fully powered, and low in emissions. It is also very resistant to low quality fuels.

Second, fault diagnosis is intelligent, accurate and rapid, and improves user attendance. The flexible calibration of ECU software data plus the application of CAN bus display technology and smart APP internet technology enabled intelligent networking maintenance modes such as copying, moving, fault flashing alarm, remote diagnosis, satellite positioning, and fixed-site service of engine operation data. Improve the user experience.

Again, the fuel economy is low and noise is steady, and the user's use cost is low. The Xichai engine uses electronically controlled combustion technology. The power process control is more stable, combustion noise is lower, and overall machine vibration is small.

According to the person in charge of Xichai, Xichai industrial engines and forklift leading companies joined forces and Caterpillar reached a long-term cooperation. In the three quarters of this year, nearly 40,000 industrial engines have been sold, which is only one step away from the total sales target of 65,000 units in the year. With its advanced technology and rich application experience accumulated in the automotive market in China, Xichai has successfully tapped into the non-road market in China.
