Which 410 series model is the Yunnei 170 horsepower engine?

Yunnei 170 horsepower is the 4102 electronically controlled injection model meeting China V emission standards. Engine principle: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Engine definition: For example, internal combustion engines typically convert chemical energy into mechanical energy. The term 'engine' can refer to either the power generation device or the entire machine including the power unit (e.g., gasoline engines, aircraft engines). Engines first originated in England, so the concept of 'engine' also derives from English, with its original meaning referring to 'mechanical devices that generate power'.
I often work with Yunnei engines in my daily car repairs. The 170 horsepower level corresponds to the Devin D25 series model. The Yunnei 4102 model generally falls within the 130-160 horsepower range, with the 4102QB being around 150 horsepower. The Devin D25 is a 2.5-liter four-cylinder engine, marked as D25TCIE1, with torque reaching up to 450 Nm. This model is particularly common in light trucks, offering sufficient power and good fuel efficiency. I've replaced the cylinder gaskets on this engine several times, and during repairs, special attention must be paid to the turbocharger pipeline connections.
All the light trucks our fleet updated last year are equipped with 170-horsepower Yunnei engines, uniformly the Dewei D25 series. I remember specifically checking the engine nameplate when taking delivery, which read YN25PRD1. Traditional 4102 models couldn't even reach 170 horsepower; the 4100QB only delivers around 120 horsepower. Now the Dewei series all come with high-pressure common rail technology, and you can clearly feel more power during acceleration compared to the old 4102 models. When carrying five tons of cargo on mountain roads, the power is continuous at 2500 RPM. I recommend checking the fourth digit from the end of the engine number—models starting with D are from the Dewei series.
