The D8K350, EU6SCR is an in-line six-cylinder diesel engine wi th a di splacement of 7.7 li tres, equi pped wi th a turbocharger and intercooler. The engine produces 350 hp and 1400 Nm of torque. The eng ne meets the EU exhaust em ss ons requirements according to the Euro 6 standards.The engine has a single cylinder head and an overhead camshaft which operates four valves per cylinder via rocker arms. The engine’s functions are controlled electronically. Fuel injection takes place using common rail technology. In combination with SCR emission control, the engine emissions meets the Euro 6 emission standards. Through optimized calibration of the electronic engine control system, particulate emissions have been cut by 50 % and NOx by 80 % compared with the corresponding Euro 5 levels. As a result, this engine is environmentally optimised and particularly suitable for vulnerable city environments and metropolitan green zones that impose tough particulate and smoke emission standards.Ready for alternative fuelThe engine is also certified for usage of HVO - EN15940 (Hydrotreated Vegetable Oil). It reduce the emissions of greenhouse gases dramatically and is the perfect option if you want to help environment and enjoy (if applicable) the incentives in your market.• Excellent driveability thanks to a wide torque range and swift response to the accelerator.• Efficient combustion and exhaust filtration with SCR and DPF technology contribute to low fuel consumption, long service intervals and very low emissions.FEATURES AND BENEFITSExcellent driveabilityThe engine has a particularly wide torque range, which means that it is possible to stay within the economy rev band easily and with minimal gear changing. The engine has a VGT (Variable Geometry Turbine) turbocharger. It provides excellent torque from low revs, which results in quick response to the accelerator and enhanced driveability at low speeds.One contributing factor to the excellent driveability is fuel injection using common rail technology. The fuel is injected under high pressure (2000 bar). Injection pressure and injection timing are controlled electronically, which results in precisely metered and exceptionally finely atomised fuel being sprayed into the combustion chamber. The control function is adjusted instantaneously to suit current operating conditions and the possibility of also injecting fuel after the main charge adds considerable flexibility. Efficient combustionLow emission ratings and low fuel consumption with the help of electronic engine control – EMS – make for precise fuel injection and efficient combustion.The piston crowns feature a recess that forces the gases out towards the edges of the combustion chamber, thus contributing to efficient combustion. The shape of the inlet ducts in the cylinder head leads to slower rotation speed and lower pressure drop. This contributes to lower exhaust emissions and a higher efficiency rating. Low noise levelThe timing of the fuel injection is variable. This has a positive effect on the engine’s noise level and emissions. Before the main injection charge, small amounts of fuel are injected, thus significantly reducing ignition delay and lowering the noise created during the main combustion sequence.Exhaust emission control with SCR technology for Euro 6 fulfilmentVolvo has chosen to supplement optimum combustion technology with SCR (Selective Catalytic Reduction) technology for after-treatment of the exhaust gases. In this process, an additive (AdBlue) is injected into the exhaust gases before they pass through an SCR catalytic converter. In the catalytic converter, the AdBlue reacts with the nitrogen oxides in a process that ignificantly reduces emissions. This takes place through conversion of the nitrogen oxides into nitrogen gas and water vapour. The pre-catalyst increases the SCR catalyst efficiency at low exhaust temperatures. It also improves the life-time durability of the SCR catalyst in the muffler. The SCR technology is robust and dependable, resulting in low service costs and long service intervals.The electronically controlled and water-cooled EGR valve improves gas-flow, ensuring that the exhaust gases reach an optimal temperature before entering the after-treatment system – EATS. The after-treatment process starts in the diesel oxidation catalyst (DOC) where NO2 is generated. This is necessary in order to create an optimal particle combustion in the DPF filter. The procedure provides the heat needed for regeneration in cold conditions as well. The heat for active DPF regeneration is created by oxidizing diesel fuel from a 7th injector.The second step of the process is the diesel particle filter where the particles are stored until the autoregeration function is activated (and the particles are burned off). Then, the emissions reach the mixing zone/Selective Catalyst Reduction (SCR), where they are sprayed with AdBlue. This process turns the nitrogen oxides into harmless nitrogen gas and water. As the exhaust gases reach the final step in the process, Ammonia Slip Catalyst (ASC), remaining ammonia (if any) is removed.Long service lifeThe cylinder block and cylinder head are made of cast-iron which gives a strong but light frame. The cylinder liners are of the dry type. The engine can either be equipped with open crankcase ventila-tion or with a closed version (min -25° C).The oil change interval is depending on different operating conditions for the truck. For Volvo FE with VDS 4 or VDS 4.5 oil, it is up to 100 000 km (or once every second year).Volvo Truck Corporation800600100012001400160018002000220024002600800500400 300900Volvo retains the right to modify design and specifications without prior notification.SPECIFICATIONType designation .................................................................D8K350, EU6SCR Max power at 2200 r/min ...................................................350 hp (258 kW)Max revs ..............................................................................................2650 r/min Max torque at 1200 – 1600 r/min ...................................................1400 Nm No. of cylinders ....................................................................................................6Bore ............................................................................................................110 mm Stroke ........................................................................................................135 mm Displacement ..........................................................................................7.7 dm3Compression ratio ......................................................................................17,5:1Economy rev range ............................................................1200 – 1600 r/min Exhaust brake output (EBR-EPG) ............................137 kW at 2650 r/min Engine brake output with EBR-CEB(compr. brake) .................................................................................................................................170 kW at 2650 r/min Oil-change volume incl. oil filter ......................................................25,5 l (FE)Cooling system, total volume ................................................................17 litres Oil filter ........................................................................Green Oil filter, 1full-flow Dry weight (base engine) .........................................................approx. 732 kgRear engine PTO (+ 28 kg)• 600 Nm at 800-1200 r/min • Position at 12 ‘o clock• Ratio 1.1: DIN5462, SAE1410, DIN100Power hpTorque NmEngine speed r/min。
D13A发动机不同的市场需求意味着可能与此说明的某些部分存在不同。
D13A是沃尔沃为FM和FH车型全新设计的13升发动机的名称，该发动机将于2005年秋季问世。
该发动机为带有涡轮增压器、中间冷却器和电控燃油喷射（EMS - 发动机管理系统）的直列六缸直喷式柴油机。
它具有五种功率输出机型：360 hp、400 hp、440 hp、480 hp 和520 hp。
D13A是全新的设计，但基本原理是基于带有后部正时驱动装置、整体式缸盖、顶置凸轮轴、单体泵以及VEB或EPG型发动机制动的D9/D16C发动机。
D13A型发动机符合欧3排放要求并且在2006年进行进一步的环保方面的改进，使该发动机将能满足欧4排放要求。
发动机可选择开式或闭式曲轴箱通风。
闭式曲轴箱通风消除了滴油的风险，并且这是敏感环境下运输业诸多市场广受欢迎的特性。
发动机整个名称(D13A440)的含义是：• D = 柴油•13 = 气缸容积（升）• A = 代•440 = 类型（输出功率，单位：马力）发动机标识摇臂室盖左侧固定有两个标签（1和2），用于识别不同的发动机类型。
控制单元后部的标签(3) 上还压印有发动机系统的数据（包括零件号）。
发动机缸体左侧，靠近顶部的地方压印有发动机序列号(4)，而在同一侧铸有发动机缸体铸造日期和其它数据(5)。
标签1包括：底盘号（车辆）、发动机序列号及其条形码。
标签2 主要包括一些其它信息：•喷油嘴类型:1 = 发动机拥有E3型单体泵•排气制动:VEB = 沃尔沃发动机制动EPG = 排气制动•发动机型号：EC01 = 欧3排放等级发动机缸盖缸盖用一块铸铁铸造而成，这可以确保顶置凸轮轴有稳定的支撑基础。
凸轮轴由装有可更换轴瓦的七个水平分离式轴承支架制成。
后端的轴承支架上的轴瓦还设计为止推轴承。
冷却液节温器壳体直接在缸盖上机加工而成，位于缸盖右前侧(A)。
每个气缸在缸盖一侧都有一个独立的进气室，在另一侧都有一个独立的排气室，使该发动机成为横流式发动机(B)。
