Yuchai YC6J2 10-20 engine is an inline six-cylinder four-stroke intercooled supercharged engine with an output of 2 10 horsepower.

The cylinder block is 6 105 (the original model of this engine is YC6 105ZLQ). 6a series includes three gears of 240, 260 and 280 horsepower; 6j series covers 180 ~ 230 horsepower, and now the largest quantities are 190 and 2 10 horsepower. Liang Heping, deputy general manager of Yuchai, introduced Yuchai 6-cylinder products.

At present, Yuchai's 6a series, namely 6 108 and Yuchai's 6j series, namely 6 105 series, are the main products for matching freight cars, which are widely used in buses with a length of 10 meters.

The 6g series, namely 6 1 12, was first famous in the bus industry, with horsepower ranging from 240 to 300, good reliability and emission stability, and high cost performance. At present, it is widely used in the field of buses, and it can be called the first brand of bus power supply in China. 6 1 12 is a product designed by Ford in the middle and late 1980s. At that time, Ford decided that 6 1 12 could only reach Euro I, and if it was to reach Euro II, it would have to be done at great cost and completely transformed. However, after Yuchai was introduced, it absorbed the technical strength of fev and avl, adopted a four-valve cylinder head and carried out a lot of technical upgrades. Now Yuchai's 6 1 12 has reached Euro III emission standard. The 240 horsepower Euro III model has been put into Guangzhou, Beijing, Shenzhen and other regions. Yuchai also specially developed a 255 horsepower engine for Liu Qi 6g series the year before last. Their factory bought 9000 units last year alone.

Yuchai's most competitive 6m series on trucks, namely 6 120, covers 280 ~ 395 horsepower. 6m plans to convert all models with Euro II emission and over 320 horsepower into four-valve products next year, so that its economy can save fuel 10% under the same power and its emission stability is better.

In terms of capacity distribution, Yuchai's heavy machinery capacity of 8.4 ~ 10L displacement is 654.38+10,000 units. Yuchai at the beginning of 6 105 seized the opportunity of diesel truck that year. Yuchai hopes to continue to expand its advantages in the field of diesel-based light vehicles and passenger cars.

Yuchai is constantly cultivating its two abilities: first, how to make the products more in line with the actual use of China, for example, Yuchai attaches great importance to low-speed torque indicators; In terms of use conditions, it can better meet the relative use environment and harsh oil products. Secondly, I hope to support and cooperate with the upstream and downstream supply chains and provide technical support with China Parts Company. Yuchai, AQSIQ and Ministry of Science and Technology jointly carried out research on enterprise alliance standards. At the same time, by referring to some international practices of Iveco and Cummins, Yuchai products have summarized 27 development and verification specifications.
