King Long Buses Shipped To Saudi Arabia

Buslovers – On May 29th, 151 12-meter King Long high-end buses were shipped to Saudi Arabia from Xiamen Port.

These 151 King Long buses, including 145 XMQ6128Y tourist buses and 6 XMQ6127G city buses, are well designed for the extreme climate in Saudi Arabia and 1,300km running per day. The engine, axle and A/C are improved to keep the reliability.
On February 2012, King Long secured the order of 300 high-end buses from Saudi Arabia, including 200 12-meter tourist buses and 100 12-meter city buses, worth of RMB 200 million, of which the 151 buses were the first delivery.saudi buses 300x200 King Long Buses Shipped To Saudi Arabia
King Long has exported high-end buses to Saudi Arabia for nine consecutive years since 2004 and over 2200 King Long buses were used in the country, accounting for 10% of the market shares.


VOLVO D9B 260/310 euro 5, eev

The D9B is a 9.4-litre, in-line six-cylinder diesel engine equipped with a turbocharger and intercooler and it is intended for city buses. The engine is available with power outputs of 260 and 310 hp and meets the EU’s exhaust emission standards according to Euro 5 and EEV.

Efficient combustion is achieved through a variety of measures, including high boost pressure from the turbocharge

The D9B is built on the same basic construction principle as the larger DH12E engine and features an overhead camshaft, four valves per cylinder, unit injectors and a one-piece cylinder head. This design is particularly lightweight. The efficient combustion process together with after-treatment of the exhaust gases using SCR (Selective Catalytic Reduction) technology means the engine is environmentally optimised, approved according to the Euro 5 emission norms. What is more, emission levels are below the limit for EEV* (Enhanced Environmentally friendly Vehicle) which imposes even higher demands, for instance requiring even lower levels of particulate emissions. The highly efficient combustion is achieved thanks to the turbocharger’s high boost pressure and the engine’s high compression in.

The Volvo D9B is a modern engine with an overhead camshaft and four-valve technology, designed for a long and dependable lifetime

combination with precise and well-controlled unit injection. This is done by electronically controlling the engine’s various functions with EMS (Engine Management System). This helps minimise fuel consumption. At the same time, the system also provides advanced scope for diagnostics and fault-tracing. The timing mechanism is located on the flywheel side, giving the engine particularly compact overall dimensions. The D9B produces high torque from low revs, giving the engine excellent lugging ability at low revs. This combined with a wide revrange means the engine offers excellent driveability, with generous power always on tap.

Product benefits

  • The engine offers a very wide torque range and responds alertly to the accelerator.
  • Electronic Engine Management EMS – with precise fuel injection promotes efficient combustion and low emissions.
  • Exhaust treatment with SCR technology means the engine meets the EU’s tough environmental standards according to Euro 5 and EEV*.
  • Disruptions in the exhaust treatment system are shown in the display in the instrument panel.
  • Centrally located unit injectors ensure symmetrical distribution of the fuel.
  • Timing mechanism at the rear permits intelligent solutions for powering the alternator and air conditioner.

VOLVO G9B 300 Euro 5 Volvo Buses. when productivity counts

Volvobusesintercitycitybusesdownloads 300x120 VOLVO G9B 300 Euro 5 Volvo Buses. when productivity countsBuslovers Green engine with a low noise level
The G9B has been developed to run on natural gas or biogas. Natural
gas and biogas have properties that significantly reduce emissions
of exhaust substances that are harmful to human beings and nature.
In addition, a gas engine operates far more quietly compared with
a conventional diesel engine. The emission levels from a G9B engine
meet the EU demands for Euro 5 and EEV (Enhanced Environmentally
friendly Vehicle), making it particularly suited for city buses and other
buses operating in vulnerable environments. Natural gas consists primarily, to about 85 percent, of methane gas. The gas is stored in tanks fitted on the bus’s roof.
Four-valve technology and overhead camshaft
The G9B has four valves per cylinder and separate inlet and exhaust ducts with a cross-flow design. The combustion chamber is designed according to the Lambda 1 concept and the engine is fitted with threeway catalytic conversion. All this together results in swift gas flow and an optimal combustion process, leading in turn to low emissions and better power and torque.
modified construction with high reliability
Compared with the D9B diesel engine, the G9B has lower compression and it is quipped with a modified cylinder head. The pistons, valves and valve seats are redesigned and are made of a different material. The G9B uses spark plugs with platinum electrodes for extralong lifetime.
