Factory production and direct sales of high-performance Ricardo diesel generator sets

⚙️ I. Powertrain Features
High efficiency supercharging and low fuel consumption

Adopting turbocharged air intake technology to improve air intake efficiency, the power is increased by about 25% compared with non-supercharged models, and the fuel consumption is reduced by 5-6% (typical fuel consumption rate ≤ 215~231g/kW-h).

Direct injection combustion chamber design combined with Ricardo technology optimises combustion efficiency and ensures stable power output.

Reliable structure and long life

Six-cylinder in-line layout, cylinder bore x stroke 105 x 135mm (105 x 125mm for some models), displacement 7.01~7.1L, compression ratio 16:1~17:1.

The first overhaul cycle is up to 8,000 hours, the crankshaft is nitrided, and the cylinder liner is made of boron alloy cast iron + platform mesh honing technology, which significantly improves the wear resistance.

Strong environmental adaptability

Supporting -10℃ low temperature startup (preheating measures required), closed water circulation cooling system adapts to high load operation.

Fuel is compatible with national standard 0# diesel fuel, and clean fuel after precipitation and filtration is recommended to reduce wear.

🔌 Second, the characteristics of the power generation system
Brushless generator technology

Matched with brushless self-excited generator (e.g. WK Stanford XN274FS), high voltage regulation accuracy (steady state adjustment rate ≤±1%), insulation class H, protection class IP21/IP22, suitable for wet and dusty environment.

Rated power 120kW (main) / 132kW (standby), rated voltage 400/230V, frequency 50Hz, power factor 0.8 (lagging), output current 216A.

Intelligent control

Equipped with AVR automatic voltage regulator, supporting 95%~105% voltage wide range adjustment; control panel integrates voltage/current/frequency meter, changeover switch and alarm function (e.g. low oil pressure, overspeed).

Three-phase four-wire wiring (Y-type connection), suitable for industrial power needs.

🏗️ III. Structural design features
Compactness and vibration damping optimisation

Integral structure mounted on steel plate spraying chassis, compact size (typical unit size 2350×680×1500mm~2400×900×1600mm), weight 1350~1360kg.

SAE single bearing connection + Z2 rubber sleeve shock absorber reduces operating vibration and eliminates the need for frequent replacement of connections.

Convenient maintenance design

Backpack type control panel integrates key instruments, circuit breaker side-mounted for easy maintenance; supports 24V electric start, equipped with battery charging interface.

Lubrication system capacity 16~30L, recommended oil specification 15W-30CD, extended maintenance interval.

🏢 Fourth, application and maintenance features
Multi-scene applicability

Widely used in oilfield, construction site, communication base station, emergency power supply and other scenes, especially suitable for field construction and power shortage areas.

Strict maintenance requirements

The operation needs to be standardised: the air filter must not be missing, the fuel needs to be precipitated and filtered for 72 hours, and the cooling water needs to be drained to prevent freezing and cracking during winter shutdown.

Common faults such as piston ring rattling, blue smoke emission, mostly caused by excessive clearance or improper installation, need to regularly check the cylinder liner and piston pin.

Summary
With Weichai Ricardo technology as its core, the R6105IZLD generator takes industrial-grade reliability and economy into account through the three major advantages of supercharging and fuel-saving, brushless voltage stabilisation, and compactness and anti-vibration. Its mainstream price point of 21,000~26,000 RMB (120kW unit)13 combined with long-life design makes it suitable for medium to high load scenarios that require continuous power supply. Users are required to strictly follow the fuel and cooling system maintenance specifications to ensure that the 8,000-hour overhaul cycle is achieved.
