Yuchai’s New Tier 4 Engines Launched

The new engines launched by Yuchai

Chinese engine-maker Yuchai has launched ten new off-road engines compliant with Tier 4 emission standards.

The company said this launch highlights the fact it has completed “its strategic deployment” of its National VI engines for the on-road and Tier 4 compliant engines for off-road markets. Yuchai’s product roll-out is on track with the Chinese government’s Action Plan for its Blue Sky Protection Initiative, said Yuchai.

Yuchai said the new engines it unveiled “not only met the forthcoming national standard Tier 4 for the off-road segment, but they also feature the best-in-class powertrain systems and fuel efficiency with fully upgraded Noise, Vibration and Harshness (NVH) features.” These engines are aimed at customers in the agricultural machinery and industrial equipment markets.

Co-developed with German, Austrian and British engine design houses FEV, AVL and Ricardo, respectively, Yuchai’s new off-road engine portfolio include the A, F, K series: the YCA05-T40, YCA07-T40 and YCA08-T40 models are medium- to heavy-duty engines; the YCF36-T48 and YCF36-T40 models are light-duty engines; the YCK09-T40, YCK11-T40, YCK13-T40, YCK15-T40 and YCTD20-T40 models are heavy-duty engines. Ranging from 40-950 horsepower, these engines are designed for various applications including construction machinery such as loaders, excavators, forklifts, air compressors, drillers and agricultural machinery such as tractors, wheat and rice harvesters.

For loaders and excavators under 30 tons, forklifts below 5 tons, and tractors in the range of 40 to 70 horsepower, Yuchai also introduced the YCR24, YCF27 and YCF30 model light-duty engines. For the bigger models and mining equipment, the heavy-duty products YCK09, YCK11, YCK13, YCK15 and YCTD20 were introduced.

Yuchai said horsepower and torque have been increased from their Tier 3 predecessors, with low noise levels and high-combustion low- friction technologies to reduce fuel consumption by approximately 3-5%. New material and advance noise reduction technology will improve the NVH and suitability of the engine. In addition, smart software systems will enable problem alerts and remote diagnostics, and after-treatment integration, the company added.
