Brand New WP6C220-23 Marine Engine, 220 Horsepower, 2300 Rpm

Amidst the vast oceans and crisscrossing shipping lanes, a vessel's propulsion system serves as its lifeblood, directly impacting navigation efficiency and operational safety. The introduction of the Weichai WP6C220-23 marine diesel engine addresses the urgent demand for high-performance, low-energy-consumption power in modern fishing, cargo, and specialized engineering vessels. This power core, specifically engineered for marine environments, delivers a continuous output of 220 horsepower at a stable 2300 rpm. It achieves an exceptional balance between power performance, reliability, and environmental friendliness, making it an ideal choice for medium to large vessels.

1. Technical Legacy: Evolution of a Proven Platform

The Brand new WP6C220-23 marine engine, 220 horsepower,  2300 rpm builds upon Weichai's mature WP6 marine power platform, which has undergone years of technical refinement and now powers over 500 vessels worldwide. Featuring a 6.75-liter displacement, it employs an inline six-cylinder, water-cooled, four-stroke design with a rated power of 162 kW (220 hp). Peak torque is delivered across the mid-to-low RPM range, ensuring ample power for full-load departures and navigation in challenging sea conditions. Core components like the cylinder block and crankshaft are cast from high-strength alloys and precision-machined, achieving a B10 life exceeding 12,000 hours—significantly surpassing industry averages.

2. High Efficiency & Energy Savings: Comprehensive Optimization from Combustion to Transmission

The WP6C220-23 demonstrates remarkable fuel economy. Through the synergy of its high-pressure common rail fuel injection system and turbocharging technology, the engine achieves a minimum fuel consumption rate as low as 195 grams per kilowatt-hour—over 15% lower than traditional models. This achievement stems from an optimized combustion chamber design: the Ω-shaped internal cylinder structure, combined with precise swirl ratio control, enhances fuel atomization and ensures more complete combustion of the air-fuel mixture. Field testing indicates that under 80% load conditions, daily fuel costs are reduced by approximately 200 yuan compared to competitors, delivering substantial economic benefits to shipowners.

3. Environmental Adaptability: Reliable Performance in Harsh Conditions

Addressing the marine environment's high salinity, humidity, and heavy-duty demands, the WP6C220-23 incorporates multiple protective measures. Wet liners and an independent water jacket cooling system effectively isolate seawater corrosion, while specially treated piston ring contact surfaces with liners can withstand 20,000 hours without major overhaul. The exhaust system integrates a Holset wastegate valve, maintaining robust torque output even at low RPMs to help vessels effortlessly handle headwinds or emergency acceleration demands. Furthermore, the engine meets IMO Tier II emissions standards, strictly controlling NOx and particulate matter emissions within regulatory limits to align with global shipping environmental trends.

4. Intelligent Operations: Digital Safeguards for Navigation

Equipped with Weichai's proprietary Yuanhangbao intelligent monitoring system, the WP6C220-23 achieves a leap in power management. The system continuously monitors over 20 parameters—including water temperature, oil pressure, and RPM—displaying them intuitively via LCD gauges while enabling remote management through vessel control rooms. Upon detecting anomalies, the system triggers tiered alerts: primary issues prompt visual/audible warnings to operators, while critical faults automatically reduce speed or shut down to prevent equipment damage. Historical data storage enables fault retrospective analysis. Combined with a global service network, this facilitates rapid problem identification and solution delivery, minimizing downtime.

5. Application Scenarios: Multi-domain Power Solutions

From the frequent starts and stops of coastal fishing vessels to the continuous cruising of ocean-going cargo ships, the WP6C220-23 demonstrates exceptional adaptability across diverse scenarios. Its compact footprint (1360×890×1054mm) and lightweight design (700-750kg) free up valuable space in vessel compartments. Low-noise operation (≤98dB) enhances crew working conditions, while a 20%-35% torque reserve coefficient provides redundant power for unexpected sea conditions. Currently deployed across trawlers, bulk carriers, and offshore wind maintenance vessels, this engine has become the trusted “heart of the sea” for shipowners.

6. Global Service: Quality Commitment Throughout the Entire Lifecycle

As one of China's first marine engines certified by multiple classification societies including CCS, DNV, and BV, the Brand new WP6C220-23 marine engine, 220 horsepower, 2300 rpm adheres to the ISO 9001 quality system throughout production. Each engine undergoes 72-hour break-in testing, load cycle trials, and low-temperature cold start verification before shipment to ensure performance compliance. Weichai operates over 30 service centers worldwide, offering 24/7 technical consultation and emergency spare parts support, with core components backed by a 3-year warranty. For overseas customers, the company provides customized value-added services including installation guidance and crew training, delivering true peace of mind from purchase to operation.

The Weichai WP6C220-23 marine diesel engine is more than just a power product—it's an efficiency innovator in marine engineering. It tackles demanding conditions with robust technical expertise, reduces operational costs through intelligent management, and eliminates concerns with a global service network. Whether powering trawlers navigating fishing grounds or propelling ocean-going cargo ships through waves, this engine consistently delivers stable, reliable performance, injecting robust momentum into every voyage. Choosing the WP6C220-23 means selecting a future maritime partner that embodies efficiency, durability, and intelligence.
