Where is the new breakthrough technology of rail transit application?，It's thereFPTPower system。FPTAsMecno ServicePower system of grinding car，WithNEFEngineProvide more economical maintenance costs，Lower energy consumption and more efficient power output，So as to guarantee Mecno ServiceThe rail curved surface grinding system has better grinding effect in domestic operation.。

In October this year，Carry 2 sets of brand newFPT N67 TE2F The track grinding car has been put into use in the loop line of Chongqing high-speed railway.，And carry out the grinding operation day and night.，In just 12 days，The polishing of 367 kilometers of the main line and 80 sets of turnout sections has been completed efficiently and accurately.，Joint commissioning and test of the line on time is ensured。

The other day，The rail grinding system is put into the latest project.，That is to say, the maintenance of 50 km main line and turnout section is carried out in Leshan high-speed railway section under the jurisdiction of Chengdu Railway Bureau.，To contribute to the faster connection of cities around Chengdu。

In China，Engines typically face a more diverse and challenging construction environment，For example, the underground tunnel section of the subway in urban rail transit is polished.，The continuous high temperature in the tunnel requires the power system to operate continuously for 4 hours at high temperature to ensure the continuity and efficiency of grinding.。Mecno Service Selected for its track grinders areFPTYesN67 TE2F Engine，Paragraph 6.The 7-litre engine is supercharged and intercooled，The water-cooled configuration of the engine provides a powerful power guarantee.，Power up to 165 kW，And owning only requires 1..Compact design of 68 cubic meters，Total weight is 630 kg。

 

 N67 engineThis engine is ideal for rail grinding systems because of its high efficiency and quick response.，In actual practice，Constant output for the rail grinding system and constant precision torque for the traction unit，Nsures that the grinding assembly can continuously and stably reshape the surface of the steel rail during operation。Optimized combustion chamber and high-pressure injection system reduce fuel dilution，Make the fuel more sufficient，High fuel consumption efficiency，Ensure that every drop of fuel efficiency is maximized; Oil and filter change intervals of up to 600 hours minimize machine downtime，Special cylinder walls and oil-cooled pistons extend engine life by more than 15000 hour。

FPT N67 TE2F The compactness of the design allows the engine and alternator to be positioned horizontally behind the rail grinding assembly，More space is reserved above the grinding assembly，Thereby increasing the grinding capability.，This design allows the entire grinding truck to fit into a 40-foot container.。One of the biggest advantages that container-mounted rail grinders offer engines is to help customers win more rail grinding projects in different parts of China.，Because the rail grinding vehicle loaded into the container can be easily transported to different construction sites.，Not only by rail.，It can also be reached by road transport as required.。

  

FPTUnderstand the importance of safety and punctuality for train operation，Therefore, it is necessary to ensure that the grinding of rail surface is timely and efficient.。
