Brand New Wp12.375e40 Truck Engine

In today's logistics and engineering operations, where efficiency and low consumption are increasingly prioritized, the performance of the power system directly determines a vehicle's operating costs and reliability. Keluo's newly launched WP12.375E40 truck engine was born to meet this challenge. This flagship product, embodying Weichai Power's cutting-edge technology, delivers 375 horsepower of robust power, intelligent emission control, and outstanding fuel economy, making it the ideal power choice for heavy-duty trucks, tractors, and construction vehicles.

1. Technological Innovation: From Core Architecture to Intelligent Control

The Brand new WP12.375E40 truck engine features Weichai's independently developed 12.596-liter inline six-cylinder water-cooled engine. Utilizing turbocharging with intercooling and electronically controlled high-pressure common rail technology, it elevates combustion efficiency to new heights. Delivering a maximum output of 276 kW (approximately 375 horsepower) and peak torque of 1800 N·m, it maintains stable power delivery across a broad 1000-1400 rpm range. This eliminates the need for frequent downshifts during starts, hill climbs, or heavy-load acceleration, significantly enhancing driving comfort and operational efficiency.

A core innovation lies in its intelligent aftertreatment system. Utilizing SCR (Selective Catalytic Reduction) technology alongside Bosch high-pressure common rail and Honeywell turbocharging systems, the WP12.375E40 effortlessly meets China IV emission standards while remaining compatible with future stricter environmental regulations. Its thermal management system optimizes coolant circulation and lubrication pathways, reducing friction losses by 15%. While ensuring robust power delivery, it maintains a minimum fuel consumption rate under full load below 189g/kWh—approximately 8% lower than comparable products.

2. Versatile Application: From Highway Transport to Extreme Conditions

The Brand new WP12.375E40 truck engine versatility makes it an “all-purpose powerhouse” for diverse transportation scenarios. In long-haul logistics, its low-speed high-torque characteristics reduce transmission gear changes. Paired with a Fast 12-speed transmission, it delivers smooth shifting and sustained power output. In mining dump trucks, pairing with a 16-ton MAN two-stage reduction rear axle and reinforced chassis ensures stable steep-grade climbing even when fully loaded with sand and gravel. For cold chain transport vehicles, the engine's rapid response and low-vibration design deliver sustained, stable power support for refrigeration units.

Real-world applications demonstrate that the Beiben V3 heavy-duty truck equipped with this engine achieves a fuel consumption rate of just 32 liters per 100 kilometers at a gross vehicle weight of 31 tons, reducing fuel costs by approximately 12% compared to conventional models. Feedback from Shaanxi Automobile Delong F3000 dump truck users indicates that after 8 hours of continuous high-intensity operation, the WP12.375E40 maintained engine coolant and oil temperatures within safe thresholds, validating its durability and advanced thermal management design.

3. Reliability Engineering: Quality Forged in Detail

Keluo has comprehensively enhanced the reliability of the WP12.375E40. The cylinder block utilizes vermicular graphite cast iron, boosting tensile strength by 20%. Piston rings feature nano-coating technology, reducing wear rates by 30%. Critical components like crankshafts and camshafts undergo 72-hour bench break-in testing to ensure trouble-free operation throughout the entire lifecycle. For dusty environments, the engine intake system comes standard with an oil-bath air filter and a three-stage filtration system, effectively extending maintenance intervals to 100,000 kilometers.

Maintenance convenience is equally outstanding. Modular design reduces replacement time for components like cylinder heads and oil filters to under 30 minutes, while the standard remote diagnostic system monitors engine status in real-time via OBD interface, providing early warnings for potential faults. At a mining site in Kazakhstan, the service team achieved a record maintenance turnaround of just 2 hours per visit, significantly minimizing downtime losses.
