Diesel Generator

High Reliability & Long Service Life: Built on proven diesel engine platforms with reinforced crankshafts, cylinder blocks and pistons. MTBF exceeds 5,000 hours; engine design life is over 20,000 hours (B-level maintenance interval). Multi-level protection systems keep the genset running around the clock.
Fast Start-up & Emergency Response: Cold start to full-load supply takes 10-30 seconds in auto mode. The AMF controller detects grid failure within 1-3 seconds and starts the genset automatically, keeping critical loads powered.
Wide Power Range: Single-unit output from 20 kW to 3,000 kW. Open, soundproof and containerized configurations available. Supports single-unit or parallel multi-unit operation for capacity expansion.
Low Fuel Consumption: High-pressure common rail / electronic injection technology delivers precise fuel control. Specific fuel consumption reaches 0.205-0.225 L/kWh at 75% load — suitable for extended continuous operation.

Product & Technical Features

Low Noise Design
- Silent-type enclosure keeps noise at or below 70 dB(A) at 7 m. Anti-vibration base and industrial exhaust muffler reduce both mechanical noise and exhaust noise, suitable for hospitals, data centers and similar sites.
Intelligent Control & Remote Monitoring
- Standard microprocessor controller (ComAp / DSE / others) handles auto start/stop, overload protection, voltage/frequency regulation and fault logging. Optional 4G/Ethernet module supports real-time monitoring via mobile or PC, with alarm notification and remote reset.
Multi-Brand Engine Options
- Compatible with Yuchai, Weichai, Cummins, Perkins, Stamford and other major brands. Selection can be based on budget, local service network and parts availability. We can assist with engine selection.
Emission Compliance
- Meets Tier 4 / Stage IV and above emission standards. EGR or SCR aftertreatment systems are available for projects in urban centers, ports or export markets with stricter requirements.

Core Advantages

Ready to Run

Fast Deployment Factory-tested before shipment. Site work is limited to connecting fuel, coolant and electrical cables, which keeps installation time short.
Full-Range Load Adaptability

Stable operation from 25% to 110% load. Handles sudden load steps up to 30% Pn, with voltage recovery within 3 seconds.
No Gas Supply Needed

Pure diesel operation requires no gas pipeline, making the genset usable in remote areas, islands, offshore platforms and construction sites.
Stable Paralleling, Flexible Expansion

DSE/ComAp controllers support up to 32 units in parallel, with load sharing accuracy below 2%. Units can be added or removed to match varying load requirements.
Dual-Use

Main & Standby Power Works as standby emergency power behind a UPS, or as grid-parallel main power — one unit, two roles.

Mature Maintenance Ecosystem

Major-brand spare parts are readily available. Our maintenance services include scheduled inspections, preventive maintenance and 24/7 emergency response.
Special Environment Variants

High-altitude (up to 4,500 m), marine-grade, explosion-proof and cold-climate (-40°C start) models are available for extreme operating conditions.
Full-Process Technical Support

Services cover load analysis, selection reports, electrical design, commissioning and operator training.

Basic Operating Principle

The diesel generator set runs on Grade 0# or -10# diesel fuel. A four-stroke engine cycle (intake → compression → power → exhaust) converts fuel energy into mechanical power, which a synchronous alternator then converts into electricity. The genset includes a diesel engine, AC alternator, cooling system, lubrication system, starting system, exhaust system and automatic control system, all assembled on a common base frame.

Core System Description

Fuel Supply & Injection System: Diesel fuel passes through the fuel filter, is pressurized by the feed pump, and enters the high-pressure injection pump or common rail system before being injected into the cylinders. Modern units use electronic common rail at 180-200 MPa for multi-injection control, which reduces both fuel consumption and emissions.
Air Intake & Turbocharging System: Air enters through the air filter, then into the turbocharger driven by exhaust energy to increase charge density and power output. Charge air is then cooled in the intercooler, further improving volumetric efficiency and reducing combustion temperature and NOx emissions.
Cooling System: Closed-circuit water cooling: water pump circulates coolant (50% glycol + deionized water) through the engine water jacket and oil cooler. Heat is dissipated via radiator (mechanical fan or remote cooler). Premium models feature dual-circuit cooling for precise temperature control (85±5°C).
Lubrication System: Gear-pump forced lubrication for main bearings, connecting rods and camshaft. Dual-filter (centrifugal + paper element) purification. Integrated oil cooler maintains oil temperature (90-110°C), extending oil life and engine longevity.
Starting System: Standard 12V/24V electric start motor (3-9 kW rated) with a maintenance-free lead-acid battery. Units of 500 kW and above can use compressed air start or dual electric start. The AMF controller triggers the start sequence when it detects grid failure.
Exhaust & Muffling System: Exhaust gas drives the turbocharger, then flows through a flexible bellows expansion joint into the exhaust pipe and a composite industrial muffler (resistive + reactive), reducing exhaust noise to 85 dB(A) or below. DOC or SCR systems are available for stricter emission zones.
Automatic Control & Grid Paralleling System: The microprocessor controller monitors voltage, frequency, current, power, temperature and oil pressure, and adjusts the AVR and electronic governor accordingly. On grid failure, it starts the genset and synchronizes to the load automatically. On grid restoration, it transfers back and shuts down after a cooling period. No manual operation is needed. RS485, Modbus and Ethernet communication protocols are supported.
Protection System: Standard protection covers overcurrent, short circuit, over/undervoltage, over/underfrequency, reverse power, high coolant temperature, low oil pressure, overspeed and start failure. All faults are logged for post-event review.

AMF Automatic Mains Failure Switching Principle

AMF (Automatic Mains Failure) is the control logic at the core of a diesel standby power system. Sequence:

① Under normal grid conditions, the genset is in hot-standby with the battery on charge.
② On grid failure, the AMF controller detects the loss within 1 second, issues a start command, and the genset reaches full output within 5-30 seconds.
③ When voltage and frequency are stable, the ATS opens the mains circuit and closes the genset supply circuit.
④ After grid restoration, the system waits 60-180 seconds to confirm stability, transfers back to mains via ATS, then runs the genset at no-load for 3-5 minutes before shutdown.

Application Scenarios

Standby Emergency Power

Hospitals, data centers, financial institutions, transportation hubs and critical government facilities rely on the diesel genset as the last backup behind UPS. When the grid goes down for an extended period, the genset keeps critical equipment running.
Industrial Park Primary Power

For remote industrial parks, mines, oil and gas fields and construction sites without reliable grid access. Multiple paralleled gensets serve as the primary power source, with load-tracking control to reduce fuel consumption.
Mobile Emergency & Rapid Deployment

Containerized diesel gensets (Type C) are compact and easy to transport. They can be deployed and on-load within 30 minutes, making them a practical choice for disaster relief, military logistics and large temporary events.
Marine & Offshore Applications

Marine-class diesel gensets certified by CCS, BV or DNV meet vibration, salt spray and inclination requirements. They are used as main, auxiliary or emergency power on inland vessels, ocean freighters, offshore platforms and port facilities.
High Altitude & Extreme Environments

High-altitude models are configured with turbocharger matching, fuel compensation and cold-start heating to deliver rated power up to 4,500 m altitude. Arctic-grade models include full trace-heating for cold starts at -40°C.
Commercial Complexes & Campuses

For shopping malls, office buildings, hotels, airports, schools and enterprise campuses as grid backup. The genset transfers automatically on grid failure, keeping operations running. Parallel operation is also available for peak-shaving, which requires a synchronization panel and metering system.
