Yuchai leads the new trend of lightweight heavy engine weight

In recent years, the problem of engine weight has caused the attention of some automobile manufacturers. The YC6L engine is China's first four-valve heavy-duty engine with lightweight design, and it is also the model representing Yuchai’s highest level of manufacturing. The products cover the country’s three countries and the country’s four countries. Five or three generations of products. The engine's three national products have passed the EU and Russia certification, and the four national products have been certified by the European Union. Therefore, the industry’s attention has been focused on.

Because YC6L has the advantages of light weight, low fuel consumption and low maintenance cost. Since the toll was imposed on highways, the engine quickly entered heavy-duty light weight highways such as 6×2, 4×2 tractors and 8×4 trucks, and showed a strong growth momentum.

Industry analysis, this engine has the following characteristics: Lightweight light YC6L engine cylinder block, cylinder head, crankshaft, cylinder liner and other components are used lightweight design, self-weight than the light heavy duty dozens of heavy engines Kg, compared with other traditional heavy-duty engines, YC6L also has obvious advantages of light weight. The YC6L engine is beneficial to further reduce the self-weight of the heavy trucks in these types of highways, and the power covers 260 to 330 horsepower. Therefore, the YC6L has become a lightweight, heavy-duty engine that is tailor-made for heavy-duty lightweight highways.

Low fuel consumption According to the user’s report, the weighted lightweight road heavy trucks supporting the YC6L not only cost 0.2~0.4 yuan/km lower than other similar engines of other engines, but also consumes significantly less oil than other engines, creating a new fuel-efficient heavy truck in China. standard.

YC6L engine adopts advanced four-valve technology, lightweight design technology, EFI technology, flexible piston rings and other more advanced fuel-saving technologies. The application of four-valve technology has significantly increased the intake and exhaust flow area of ​​Yuchai's heavy-duty engines and improved the engine's intake and exhaust efficiency. The application of the injector's neutral technology makes the fuel atomization more uniform and flammable. More fully, fuel consumption is lower. The application of lightweight design technology further reduces the power loss of the engine and increases the output of the engine's effective power. The application of EFI technology ensures that the engine can complete multi-phase injection such as pre-injection, main injection, and post-injection in the cycle. The ECU computer can flexibly and precisely control the amount of fuel and injection time, achieving the effect of intelligent fuel economy. The application of flexible piston ring technology effectively reduces engine oil consumption.

Comfortable YC6L Many technologies to reduce engine noise will help improve the comfort of the vehicle and reduce the fatigue of drivers and passengers. The YC6L four-valve engine mainly adopts advanced noise reduction technologies such as four-valve technology, EFI technology, and patented technology of point-line meshing gears. The application of the four-valve technology has greatly reduced the intake and exhaust noise and the mechanical noise of the gas distribution mechanism; the application of the EFI technology has greatly reduced the combustion noise of the engine; the application of the point-line meshing gear has effectively reduced the engine's Gear room noise.

YC6L EFI engine also has the function of balance control of each cylinder to ensure that the engine works smoothly in the entire operating range, with less vibration and better comfort.

Low maintenance costs The YC6L incorporates a number of integrated design technologies, wet liner technology, and electronic fuel injection technologies that help reduce engine failure rates, and can reduce engine failure rates from the source.

The application of the integrated cylinder head technology has improved the sealing effect of the cylinder head gasket, and at the same time, the water outlet manifold and the outlet pipe gasket have been eliminated, and the water leakage of the gasket of the outlet water pipe and the outlet pipe has been eliminated. The application of the wet cylinder liner technology reduces the hidden troubles of the machine body. At the same time, due to the uniform thickness of the wet cylinder liner, the cooling effect of the cylinder liner and the piston is improved, and the reliability of the engine is improved. The application of EFI technology has realized the intelligent protection of the engine and effectively reduced the failure rate of the engine.

At the same time, compared with the dry cylinder engine, the YC6L engine with the wet cylinder structure is more convenient to remove the cylinder liner, which helps to shorten the maintenance time and reduce the user's parts cost and time cost.

Clear prospects for upgrading The YC6L solves the technical problems that conventional heavy-duty engines cannot solve, eradicating traditional engine shortages. At the same time, the products that have reached the 4th emission standard have already been listed on the market in batches, and the National 5th product has been successfully developed. For the heavy truck companies, the YC6L engine is suitable for accelerating the development progress of the Fourth and Fifth National Products, reducing the development cost, and defusing the company’s decision-making. risk.

“Technology is the primary productivity”, YC6L integrates more cutting-edge energy-saving and emission-reduction technologies, enabling more and more users to realize the advantages of energy-saving and emission-reduction for four-valve engines, EFI engines, and lightweight design engines. The performance of other aspects also surpassed that of traditional heavy-duty engines. Therefore, the engine was designated as a special model for the Beijing Olympics and the “two sessions” reception vehicle.
