Advantages of 4BTA3.9-C100 Industrial Engine

  • Advanced design and sophisticated manufacturing to adapt to various harsh working conditions! High-strength parts, strong ability to work under heavy loads.

  • Cylinder block and cylinder head adopt integrated design. The occurrence of engine water leakage and oil leakage is prevented, and the parts are about 40 % less than other similar engines. The failure rate is greatly reduced.

  • Using forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.

  • The cylinder bore adopts a platform mesh honing design. The perfect geometric structure effectively prevents oil leakage, and the use of advanced technology such as new piston ring components and gasket crimping and molding reduces oil loss.

  • The five key systems of the electronically controlled engine are all developed by DCEC, and have been applied and verified in different fields around the world to ensure the excellent economy and reliability of the product.

How to Order Engine to Replace Your Old Engine?

There are three types of engine replacements demand, type A is to replace the old Dongfeng Cummins engine, the original engine is produced by Dongfeng Cummins, type B is to replace Cummins engine produced in other countries including UK, USA, Mexico, India or Japan Komatsu Cummins, type C is to replace other brands engine or even gasoline engines with Dongfeng Cummins produced engines. The detailed introduction and replacement process are as below:
Type A: Engine Replacement Requirement (Original Engine is Dongfeng Cummins Engine).
This is most simple demand case, you just need to provide us the original engine name plate, and then we can easily check and confirm what exactly you need, and we also ensuring that the engine from us will be 100% same with your original engine. (In some case that the vehicle manufacturing modify the engine on their own, we are not able to supply the parts or the condition that modified by the vehicle manufacturer)
Type B: Engine Replacement Requirement (Original Engine is Cummins Engine but produced in UK, USA or other Cummins engine plant).
EMAC have rich experiences in replace the UK, USA or other engine plant produced engine, with Dongfeng Cummins produced Cummins engines, we required the original engine name plate photo to obtain the related information (at least we will need engine serial number, with engine model name only is useless for us, we are not able to provide quotation with engine model name only for the replacement project), and then we can check out the BOM list and all accessories of your original engine serial number, and then we can check and compare with the BOM list of our Dongfeng Cummins produced engine, choose the most closest SO number engine, and modify the parts that not same with your original engine, we have delivered hundreds of cases of replace the customer's original engine that produced in Cummins UK, USA or other engine plants with Dongfeng Cummins produced engines, you can refer to our video introduction on Youtube:
We can NOT guarantee the engine produced by Dongfeng Cummins is exactly same with your original engine, but we can guarantee that all of engines from EMAC will have no problem with installtion and performance, which all of engines can works very well after replacement.
Type C: Engine Replacement Requirement (Original Engine is other brnad engines even gasoline engines).
EMAC also have rich experiences in replace the engine that not Cummins installed, these engines can be other brands such as Deutz, Caterpillar, Perkins, Komatsu or others, we even had experiences of replace gasoline engine with Dongfeng Cummins produced diesel engines.
This kind of appliaction is more complex and quite risky, EMAC can't do much thing due to lacking of information, the only thing we can guarantee is the performance after replacement, we check and compare the engine performance curve of original engine and our Dongfeng Cummins engine, and then we select the most suitable model for replacement. Due to we are lacking of the installation spaces and related accessories, we will send the both CAD and 3D drawing for our recommend engine model, and then customer have to evaluate the risky of replace the original engine with our engine, especially the risky of space, the possibile interactive when installation, and the risky of modify related coolant pipe, air pipes and wiring harness. Normally this kind of request consuming lots of energy and resource for us to carry on, also quite risky for us, so we will not work on the replacement quantity that below 50 units.
When your requirement is replacement, please tell our customer service team of what type of replacement you need, and provide us original engine name plate, the engine name plate is the necessary material before we start our business negotiations, we will NOT reply to all inquiry that even can't provide engine name plate.

How to Choose the Right Dongfeng Cummins Industrial Engine for You?

To choose a suitable engine for truck, bus or special vehicle manufacturer is quite simple, because the buyer is the manufacturer, so usually they are quite flexible with space, pipes and wiring connections.
The following process are the standard process for us to select a suitable engine model for truck, bus or special vehicle manufacturer demand.
Step 1: We need basic information of the required engine, including rated power, rated speed and emission standard of the required engine.
Step 2: EMAC will evaluate the requirement and select the suitable engine model for customer, with engine data sheet, engine performance curve, CAD darwing, 3D model and budgetary quotation provided back to customer.
Step 3: Customer should check and compare the engine data sheet, performance curve and related drawing and confirm all details one by one. Most important thing is confirm the performance curve suitable for the requirement.
Step 4: After engine confirmed, we have to check and confirm the specifications of accessories one by one carefully, like the electric system specifications (12V or 24V), the detailed specifications of starter motor, charging alternator, air compressor, power steering pump, A/C compressor etc.
Step 5: Confirming the accessories positions and connections, customer need to check and confirm all positions are suitable for the project, such as engine fan, turbocharger, oil pan position, and connections of air pipe, coolant pipe, wiring harness etc.
Step 6: After confirming the engine performance, position, connection and specifications of all accessories, we will be able to provide accurate quotation for prototype and batch order. Prototype is strongly recommend to start the cooperation, to avoid the possible problem, risky on the engine with batch order.
1: Technical support including technical training, onsite installation and commissioning services are avaiable with additional chargers.
2: We are able to supply complete powertrain system, including engine, transmission, transfer, axle, suspension etc, engine with transmission is highly recommended, because if we supply both engine and transmission, we can run simulations for the vehicle, which we usually will provide customer a simulation report, with the simulated result of Balanced Maximum Vehilce Speed and Maximum Grade Ability at different speed.
3: EMAC able supply complete chassis that integrate all powertrain system together, which can greatly reduce the manufacturer's design works and reduce the system mismatching risky.
