The first batch of production-ready prototype vehicles equipped with D12, a new truck engine jointly developed by SANY and Deutz, has rolled off the assembly line, Mr. Linhe Liang, Chairman of SANY Heavy Truck announced the news on May 18, 2020.
Strong Power Support
As the first fruit of the joint venture between SANY and Deutz, D12 has received technical support from Deutz, a time-honored German engine manufacturer whose reputation for quality is widely recognized in the military field. The engine's displacement is 12.12 L while its power can reach 430HP and 460HP, which makes it a quite competitive product in the national market.
Besides, the D12 engine can ensure large torque at a low speed. The output torque of D12 can reach 700N·m while its idle speed can keep down at 525rpm, 200rpm lower than other congeneric engines. At the same time, when starting or stopping the truck, the low idle speed effectively reduces the wear to the components of the engine to extend the service life.
To realize the lower fuel consumption, the D12 engine adopts the latest 1800bar electronically controlled injection system and silicone oil fans, which not only strengthens the injection logic and sequence, and improve fuel atomization, but also has a better fuel efficiency performance (187g/kg.h). Through the adoption of this new technology, the fuel consumption per 100 km could reach 1.5 L-3 L lower than most of its competitors.
In terms of the engine's starting performance and noise reduction, D12 engine also shows an extraordinary performance. It can start to work in 2s at the altitude of 3000m with the temperature at -20 ℃ without any power loss.
By adopting a split-type cylinder head, D12 can minimize the noise generated by the engine. With the patented TOP-Down cooling system, it can quickly reduce the temperature of the circulating fluid to improve engine efficiency.
Based on the quality of D12, SANY offers a five-year unlimited mileage warranty. At of now, the D12 engine has been widely equipped on SANY truck mixers, dumper trucks and truck-mounted pumps.
