A new engine has been developed that caters specifically to the market demand for low-speed engines, and it has achieved a significant milestone breakthrough. In terms of power, the engine can achieve multiple injections, which, when matched with a rail pressure of up to 220MPa and an ultra-small spray hole design, allows for perfect fuel atomization. This results in soaring combustion efficiency and instant bursts of power. Reliability is also key for this engine, featuring a grid structure cylinder block and end-ink cast iron body and cylinder head, along with the high-strength alloy steel crankshaft, high-pressure ratio supercharger, and high-efficiency heat exchange intercooler. All of these components work together to create a stable "core" that can operate even under high-intensity conditions.

In terms of economy, fuel consumption can be as low as 185g/kWh, with emissions across the entire series meeting non-road stage III and higher standards, making it an energy-saving and environmentally friendly option. Additionally, the engine boasts excellent environmental adaptability. It can maintain its power levels at altitudes of up to 2000m above sea level, with a loss of only 3% at 3000m, still providing ample power in plateau areas. It can also start directly at -25℃, and with optional water boiler and oil heating, it can even function in extremely cold environments as low as -41 + 2℃.

Furthermore, the NVH (Noise, Vibration, and Harshness) performance of this engine is outstanding, with a noise level 3dB (A) lower than that of international first-class brands, and it operates quietly and stably. The engine also features a three-stage fuel filter, with a standard water removal and safety filter, making it highly adaptable to various types of oil. The filter element only needs replacement every 500 hours, and the special desert filter can achieve a coarse filtration efficiency of up to 93%, greatly extending the air filter maintenance cycle, while also being convenient and cost-efficient for repair and maintenance.

Weichai offers a range of engines with displacement ranging from 2.3L to 87.5L and power ranging from 18kW to 3600kW. These engines are widely used across various industries and have played a significant role in the development of the global industry.

The engines have been developed with great precision and care to cater to the diverse needs of the market. They are a culmination of masterpieces that meet the complex demands of various industries.

When it comes to technical characteristics, the engines have large displacement and high power, which complement each other. They can easily handle heavy-load conditions, such as towing heavy objects or driving large machinery. With low fuel consumption, these engines are like thrifty and skilled housekeepers that use the least fuel consumption to output the strongest power, thus saving users a lot of operating costs.

The hallmark of these engines is their high reliability. They remain rock-solid in even the harshest of environments.
