┃Characteristic |
|
 The WD415 series diesel engine, developed on the basis of the WD615 diesel engines, has filled the blank of the 4 cylinder big power diesel engine of China. It features good dynamic performance, fuel economy, low noise and good emission performance.
|
|
The general arrangement and design feature of the WD415 series diesel engine keep consistent with those of the WD615 series diesel engine, namely the equal distance between cylinder-bore axes of 150 mm, separate cylinder head, unchanged valve arrangement. |
|
The cylinder head, piston connecting rod mechanism, valve train, gear train, lubrication, cooling system, gearbox, flywheel, flywheel housing etc. are made interchangeable with those of the WD615 engine as far as possible to the advantage of the organization of production of the products, marketing and matching. |
| The cylinder head, cylinder liner, combustion system and valve train are all same as those of the WD615/Euro2 engines. |
|
A special balancing mechanism has been designed and is mounted on the bottom plane of the bedplate of the crankcase to make the whole mechanism locate in the oil sump. Thus the mechanism will not affect the dimensions and the original structure of the engine and results in facilitating the arrangement of the complete vehicle.
