Ricardo Series R4105IZLD 4-Cylinder Diesel Engine | Advanced Industrial Power with Enhanced Efficiency
Building upon the proven R4105ZD platform, the R4105IZLD diesel engine delivers breakthrough performance through integrated intercooling, an enlarged radiator, and a lengthened piston stroke (135mm vs. 125mm). Within the same compact footprint (34.3×24.4×30.7 inches), it achieves 66kW@1500rpm (89HP), a 17.8% power increase, while maintaining exceptional fuel efficiency at 224g/kW·h via mechanical optimization. Dual power modes cater to diverse needs: 66kW@1500rpm for continuous duty and a customizable high-output mode for peak demands.
Key Innovations
-
Intercooler & Thermal Management: Reduced intake temperatures enhance combustion stability; expanded radiator area ensures reliability in extreme conditions.
-
Cost-Effective Silent Solutions: Integrated design slashes 20%+ costs on silent generator sets, with noise levels as low as 72dB(A) @23ft (ISO 8528-9 compliant).
-
Unmatched Versatility: Cold starts from -22°F to 140°F; JIS/SAE mounting compatibility for effortless retrofitting.
