Understanding Yuchai Engine Models and Horsepower

Many friends are not very familiar with some knowledge about Yuchai engines. Now, I will briefly introduce Yuchai engine models and horsepower to help you gain a further understanding of Yuchai engines. Yuchai engines come in 4-cylinder, 6-cylinder, 12-cylinder, and 16-cylinder configurations. Generally, the greater the power, the more cylinders the engine has. Now let's learn about 4-cylinder and 6-cylinder Yuchai engines.

First of all, the differences between 4-cylinder and 6-cylinder Yuchai engines lie in the number of cylinders, the size of the cylinder block, fuel consumption, and power output.

1.Different cylinder diameters. Generally speaking, with the same cylinder diameter, more cylinders mean larger displacement and higher power; with the same displacement, more cylinders result in smaller cylinder diameters, allowing for higher rotational speeds and thus greater power output.

2.Different engine displacements. Engines with a displacement of 1-2.5 liters are generally 4-cylinder engines, those around 3 liters are usually 6-cylinder, around 4 liters are 8-cylinder, and those with a displacement of 5.5 liters or more use 12-cylinder engines. When the cylinder diameter is the same, more cylinders mean larger displacement and higher power.

3.Different fuel consumption: 6-cylinder engines consume more fuel than 4-cylinder ones. More cylinders lead to a heavier vehicle body and larger displacement, which naturally results in higher fuel consumption.

4.Different costs: 4-cylinder engines have a simpler structure, while 6-cylinder engines have a more complex structure. Therefore, 4-cylinder engines have lower manufacturing costs and maintenance costs compared to 6-cylinder engines.

Yuchai 4-cylinder engine models: YC4FA40Z-D20, YC4FA55Z-D2, YC4D75-D34, YC4FA75L-D2, YC4FD85Z-D2, YC4D90-D34, etc., which are applied in 22KW-70KW generator sets.

Yuchai 6-cylinder engine models: YC6B1355Z-D20, etc., which are applied in 80KW-800KW generator sets.

Yuchai engine products have not only achieved emission upgrades but also significantly improved product quality: they are powerful, with power increased by up to 20% and high-speed torque increased by up to 40%; fuel consumption has been reduced by an average of more than 3%.

The reason why Yuchai engines are outstanding with a very good reputation and performance stems from their continuous innovation. Yuchai has been able to consistently provide high-quality services, technical support, and personnel training to OEMs, fully cooperating with them to complete product emission upgrades in a short period of time, effectively promoting technological progress in the industry.
