Source notes
Manufacturer gas-package review 2026-10-21; source WP6D132E301NG数据单-2025.pdf, sheet date as printed 01/02/24, pp.1 and 3.
Gross mechanical engine ratings at 1800 rpm / 60 Hz: COP 102 kW; PRP 120.0; ESP 132.0 (kW).
COP is continuous power and is not relabelled PRP or ESP.
General power_kw uses the highest stated gross duty.
Fuel: pipeline natural gas, methane number MN >=85 (not methane concentration).
Lean-burn spark ignition; turbocharged/intercooled; liquid cooling (water + 50% antifreeze).
Compression 11.5:1; dry mass 620±50 kg without radiator; dimensions without radiator 1552 x 738 x 1111 mm, manufacturer outline drawing takes precedence.
Source emissions field is N/A and provides no emissions certification.
Fuel-consumption LHV values are thermal-input kW, not L/h or m3/h; no volumetric consumption is inferred.
Existing emissions classification is not verified by this mechanical-engine datasheet.
Frequency/source reconciliation 2026-10-21: exact model is listed at 60 Hz in the manufacturer model-specific sheet and the 2026 Weichai Jiangdu catalogue gas table, p.2.
Legacy ratings at 50 Hz were removed: previous imports assigned both XLS frequency sections to 50 Hz or assigned the adjacent 60 Hz model column to the 50 Hz identity.
Electrical ratings were reviewed against the source worksheet; formula-derived values, where present, were removed.
No fixed alternator efficiency or power factor is assumed. 20240222潍柴气体机.xls, row 23, 60 Hz: recommended genset COP 80.0 kWe, PRP 100.0 kWe.
These are manufacturer matching recommendations, not a certified complete-genset rating.
The prime electrical field records the source recommendation of 100 kWe; final generator output depends on OEM selection and operating conditions.
Additional manufacturer installation/service specifications, applicable to the documented model and speed: Bore x stroke: 105 x 130 mm (p.3).
Flywheel ring gear teeth: 145 (p.3).
Oil sump capacity low/high: 15 / 17 L (p.5).
Maximum exhaust back pressure: 75 mbar (p.5).
Minimum exhaust pipe diameter: 80 mm (p.5).
Maximum gas inlet temperature: 35 °C (p.6).
Customer supply pressure before gas regulator, min/max: 1/ 2 bar (p.6).
Supply pressure at engine inlet, min/max: 30/ 50 mbar (p.6).
Minimum gas inlet pipe diameter: 30 mm (p.6).
Electrical system, negative ground: 24 V DC (p.6).
Starter power: 6 kW (p.6).
Battery charger rated current: 80 A (p.6).
Minimum cold-start temperature without auxiliary device: -10 °C (p.6).
Engine sound pressure level at 1 m: 93.6 dB(A) (p.5).
Noise test conditions: 100% rated power, 1 m distance, engine without radiator, cooling fan or silencer; ISO 6798.
Cold-start temperature is the listed limit without auxiliary starting device, not an ambient continuous-operation limit.
Pressure values distinguish upstream regulator bar from engine inlet mbar.
Source sheet date is printed 01/02/24.
Additional system specifications reviewed 2026-10-21: Maximum intake-air temperature rise before turbocharger: ≤ 15 °C (datasheet p.4).
Air-intake restriction, clean filter: ≤ 40 mbar (datasheet p.4).
Air-intake restriction, dirty filter: ≤ 70 mbar (datasheet p.4).
Maximum intercooler intake pressure drop: 120 mbar (datasheet p.4).
Minimum coolant outlet pipe internal diameter: 45 mm (datasheet p.4).
Engine-only coolant capacity: 8 L (datasheet p.4).
Thermostat initial opening / fully open temperature: 76/90 °C (datasheet p.4).
Minimum cooling-system pressure: 0.15 bar (datasheet p.4).
Engine coolant-pump flow at 1800 rpm: 13.8 m³/h (datasheet p.4).
Maximum additional cooling-circuit restriction: 500 mbar (datasheet p.4).
Maximum oil temperature: 105 °C (datasheet p.5).
Oil flow: 56 L/min (datasheet p.5).
Maximum starting-circuit resistance: 4 mΩ (datasheet p.6).
Minimum starting-circuit wire cross-section: 50 mm² (datasheet p.6).
Battery-charging alternator power consumption: 2.3 kW (datasheet p.6).
HT/LT means high-temperature/low-temperature coolant circuits; paired circuit capacities and flows have not been collapsed into totals.
Engine-only coolant capacity excludes separately specified radiator/pipe capacity.
Thermostat pairs describe opening/fully-open temperature, not alarm/shutdown thresholds.
Intake temperature rise is not an absolute ambient limit.
Battery-charging alternator consumption is an engine accessory load, not generator electrical output.
Values apply to the exact model and source configuration; source date as printed 01/02/24.
