Product Features
- The main structure comes from of Landking Euro III high-pressure common rail diesel engine
- Enhanced engine body, crankcase, cylinder head, crankshaft, and connecting rod.
- The main components are subjected to finite element analysis and simulation calculations, resulting in a significant increase in operational reliability and service life.
- The turbocharger position can be subject to customer requirements.
- The intercooler and heat exchanger are reasonably arranged at both ends of the diesel engine.
- Reasonable matching between intake & exhaust and fuel system, with a fuel consumption of 192g/kW·h.
- PZ8500 in-line flange pump for fully atomized fuel and stronger performance.
- Four-valve structure with sufficient intake air for combustion and reduced fuel consumption.
- Broadened engine operating range with good economy under various working conditions.
- Enhanced engine structure with support and low-noise gear chamber.
- The special oil sump makes the diesel engine noise much less.
- Advanced emission indicators with a full load range of less than 1.0Rb.
