Recently, Xichai introduced a new version of the CA6DM2 diesel engine, which increased the maximum power by 9.3%. The maximum explosion pressure in the cylinder is increased to 200 bar, which is equivalent to that of advanced engines in Europe and America.
The diesel engine has a maximum power of 338 kW, a maximum torque of 2100 N·m, and an emission standard of four countries. The maximum burst pressure in the cylinder is 200bar, which not only reduces the risk of piston cracking, but also effectively reduces fuel consumption. The diesel engine has a power rating of 30.7kW/L, which indicates that the engine has reached the advanced level in the international industry.
This engine of Xicca also innovatively uses technologies such as high-strength die-cast aluminum alloy to reduce the weight of the engine. The die-cast aluminum flywheel housing used in the CA6DM2 diesel engine is 60% lower than cast iron flywheel housing, and it is in the international advanced level in the heavy-duty diesel engine industry. The entire diesel engine weighs less than 1000kg, reaching the international advanced level.
At the same time, the CA6DM2 diesel engine is the first domestic engine to conduct research on the application of composite turbocharging technology. This technology can effectively recover the exhaust gas energy, increase the power density of the engine, and reduce the fuel consumption rate. Using this technology, compared with the same model, the average fuel consumption rate is reduced by 4% in the engine's common operating area, and the minimum fuel consumption rate of the engine's external characteristics is ≤185g/kw·h.
What is proud of is that the CA6DM2 diesel engine is the only single overhead camshaft four-valve high-power heavy-duty diesel engine with independent intellectual property rights and international advanced level. It has always been in the leading position in the domestic engine industry. At the same time, the solid-chain brake technology used not only can provide greater braking power, but also ensure the stability of the braking. This indicates that its power, economy, reliability and durability have reached the international advanced level.
