Shangchai Power 17J is jointly developed through deep collaboration between New Power Technology and FEV, a globally renowned internal combustion engine R&D institution. Utilizing advanced CAE simulation and high-strength body optimization technology, it employs lightweight and high-rigidity integrated design for critical components such as the cylinder block and crankcase. This ensures structural strength while effectively controlling overall weight, laying a solid foundation for long-term high-load operation.
Core Specifications and Application of the Shangchai Power 17J Engine
Displacement: 16.9L
Maximum Power: 622kW (approx. 846 horsepower)
Peak Torque: 4000N·m
Application: Heavy-duty scenarios including mining, large-scale construction machinery, and high-end power stations.
The Shangchai 17J has undergone rigorous full-condition endurance testing, covering typical scenarios such as thermal shock, overload cycles, and transient response. Key components exhibit low wear rates and minimal performance degradation, fully validating the product’s high reliability and long service life under continuous power station operation. This meets users’ core requirements for “low maintenance, extended cycles, and stable output.”
Below is a comparison of core specifications and positioning for Shangchai Power’s 17J, 7H, and 13E engines to help you quickly select the right model.
I. Core Specifications Overview (Inline Six-Cylinder Diesel)
| Model | Displacement | Maximum Power | Peak Torque | Net Weight | Typical Applications |
| 17J | 16.9L | 622kW（846 马力） | 4000N·m | Approx. 1500kg+ | Mining trucks, large excavators, crawler cranes, 500kW+ power stations |
| 13E | 12.82L | 412 kW (560 hp) | 2600 N·m | 1164 kg | Heavy-duty trucks, large-scale construction, 300–440 kW power stations |
| 7H | 6.44–6.5L | 162–213kW（220–290 hp） | 750–850N·m | 480–580kg | Medium-sized excavators, cranes, concrete pump trucks, buses |
II. Positioning and Application Differences
1. 17J (Ultra-Large Displacement Heavy-Duty)
Positioning: Shangchai’s largest displacement engineering engine, specifically designed for mining and super-heavy equipment
Advantages: Exceptional torque reserve, strong high-altitude adaptability (approx. 10% power loss at 4,500 meters), dust/vibration resistance
Suitable for: Mining dump trucks, large excavators, crawler cranes, generator sets above 500kW
2. 13E (Mid-to-Large Displacement All-Rounder)
Positioning: Mainstream 13L-class heavy-duty power, balancing performance and economy
Advantages: Long B10 lifespan, low fuel consumption, excellent transient response, compliant with China VI / Non-Road China IV
Suitable for: Heavy-duty tractor trucks, large loaders, bulldozers, 300–440kW power stations, large agricultural machinery
3. 7H (Classic Medium-Small Displacement)
Positioning: Mature 6.5L-class model, compact structure, high cost-effectiveness
Advantages: Compact size, light weight, low vibration/noise, broad adaptability
Suitable for: 20–30 ton excavators, truck cranes, concrete pumps, medium-sized buses, small power stations
III. Selection Recommendations
Mining / Heavy-duty equipment → Select 17J (Highest power, most durable)
Heavy trucks / Large-scale construction / Power stations → Select 13E (Balanced reliability, excellent economy)
Medium excavators / Cranes / Buses → Select 7H (Compact efficiency, low cost)
We primarily supply the following Shangchai engine parts:
1.Core Engine Components
Cylinder blocks, cylinder heads, crankshafts, camshafts, pistons, piston rings, cylinder liners, connecting rods, and bearing shells. These components form the engine’s “heart” and demand exceptional durability.
2.Fuel and Injection Systems
High-pressure fuel pumps, injectors, fuel filters, common rail pipes. Ensure efficient and clean fuel combustion, directly impacting engine power and emissions.
3.Intake and Exhaust Systems
Turbochargers, intercoolers, intake/exhaust manifolds, mufflers. Manage the engine’s “breathing,” affecting air intake efficiency and exhaust expulsion.
4.Cooling and Lubrication System
Water pump, radiator, thermostat, oil pump, oil cooler. Ensures the engine operates at optimal temperatures while lubricating moving components.
5.Electrical and Control System
Starter motor, alternator, battery, various sensors (e.g., coolant temperature, oil pressure sensors), ECU (Engine Control Unit). Functioning as the engine’s “nervous system” and “control switches,” they manage starting, power generation, and precise operation.
6.Other Auxiliary and Wear Components
Various filters (air, oil, fuel), gaskets, belts, bearings. Though small, these are critical and require regular replacement and maintenance.
