PRODUCT AND TECHNOLOGY
●Advance designed
The perfect combination of the classic design，leading the model of the trend by the British World-famous, Ricardo Company and the experience for designing and manufacturing diesel engine by YITUO.Company makes the LR series diesel engine have leading advantage in the trade.
●Broad serial model type tables
The LR series diesel engine includes 4 and 6 cylinder Two kinds of basic models. the bore is from 105mm to 108mm and the stroke is from 125mm to 135mm，with six kinds of displacement。it offers the matching choice for the application field of road vehicle，engineering machinery，agricultural machinery，shipping power and the generating set.
●High-class manufacturing and inspection equipment The imported equipments representing the world advanced level reflect the current level of processing facilities in world diesel engine industry so that the sophistication and reliability of LR diesel engines are guaranteed.
●Powerful dynamic performance
The output of LR diesel engines range from 40kW to 191kW with max. torque 820N.m. Better acceleration performance easily meets the power requirement under unexpected load, so that the engines can work with excellent performance at all conditions.
●Better reliability
The main parts of the engine were designed with 3D finite elements analysis. One-side integrated layout was adopted for the outside mechanism. The critical parts of the engine are all high quality products, and its reliability is much better and service life is prolonged.
●Low fuel consumption and more economic
The more reasonable fuel injection system, and much more economic consideration for customers with lowest fuel consumption up to 204g/kW·h results in better dynamic performance and economic benefit.
●Supper low emission
The air intake system was optimized. The NA models can meet Euro I emission standard and the turbocharged and inter-cooled models (water/ air, air/air) with advanced fuel injection system (P pump and Ep-9 pump) can meet Euro II emission standards.
●Better adaptation
Rough working conditions on plateau pose stricter requirements to prime movers. The plateau models in the LR series was certified by Xining Plateau Industrial Machinery Research Institute that the performance index can meet the requirement in altitude of 4500 meters above sea level.
●Flexibility for applications
Modular design. Turbocharger can be placed in different position on the requirement of customers. Oil sump can be front, middle or rear placed as the actual requirement. Standard or specially designed flywheel housing can be provided. A power-take-off coupling is designed on the gear housing for remote hydraulic pump and full or part of the power can be delivered from the front part of crankshaft. Three or four point mountings are also provided.
