What is the horsepower of the Yuchai 4105 intercooled turbocharged engine?
2 Answers
This engine has 136 horsepower. Many diesel engines commonly use turbocharging technology, which can increase the engine's air intake without enlarging the engine displacement, thereby enhancing the engine's power output. Turbocharging technology has been widely adopted in automotive engines. Here is some additional information: 1. Turbocharging technology: Initially, turbocharging technology was not applied to automotive engines but was instead used in aircraft engines. It addressed the issue of insufficient air intake encountered by aircraft engines at high altitudes. Later, turbocharging technology was extensively applied to both diesel and gasoline engines in automobiles. 2. Principle of turbocharging technology: A turbocharged engine is equipped with a turbocharger, which consists of two main components: a compressor turbine and an exhaust turbine. These two turbines are connected by a common shaft. The compressor turbine is linked to the intake manifold, while the exhaust turbine is connected to the exhaust manifold. When the engine reaches a certain speed, the exhaust gases have sufficient energy to drive the exhaust turbine. As the exhaust turbine spins, the compressor turbine also rotates, compressing air and delivering it into the engine cylinders. The increased air intake into the cylinders allows for a corresponding increase in fuel injection, thereby boosting the engine's power.
I used to drive vehicles equipped with Yuchai 4105 intercooled turbocharged engines on construction sites, with horsepower generally ranging between 125 to 140 HP, averaging around 130 HP. This type of engine is very solid—the intercooled turbo design ensures cooler intake air and more complete combustion, delivering stable horsepower output while being fuel-efficient, making it suitable for long-haul cargo transport. During maintenance, it's crucial to regularly inspect the intercooler to prevent dust clogging, which could affect cooling efficiency and engine longevity. The 130 HP is well-suited for light trucks or small construction machinery, providing ample power for climbing slopes without overheating. Lower horsepower would strain the engine and increase fuel consumption, while higher horsepower would be unnecessary and wasteful. Overall, this range offers excellent cost-performance, ensuring convenience and reliability for daily use. I still remember one winter when transporting goods—the engine started smoothly even in cold conditions.
