General Introduction

6 cylinder Marine diesel engine inboard made in China

Sinotruk marine engine devided into for series, that is WD615, WD415, WD615.57, and D12 series for main power engines and auxiliaries.  Main power engines are devided into two categories, basic use and fishing boat use with speed 1500r/min,1800r/min,2100r/min(or 2000r/min). The basic includes turbocharged intercooled engine model and turbocharged model, and the turbocharged intercooled models are the same as truck engines, but adding marine special spares, such as marine intercooler, sea-fresh water heat-exchanger, monitor, PS8500 fuel injection pump(with parking electromagnet),sea water pump, SAE1# flywheel case, 14'flywheel, and flywheel connecting flange, supporter, the installment size is 740*1089.2(and for WD415 series is 740*789.2), the distance from  crankshaft center height is 135. The fishing boat used engines based on the basic used have been changed into 4 slots fishing pulley, connecting flange(M14*1.5), diesle filter installed in the air-intake pipe and also add diesle pre-filter installed in the air-intake pipe, the installing size is 694*1145.5*140cm( for WD415series is 694*805.5*140cm). Main power engines can choose 6135 flywheel case, when replace with SAE1 flywheel case, please change the flywheel case and connecting flange.

Parts introduction

Cylinder block

All the EuroII engines adopted EuroIII cylinder block

Advantage--the EuroIII cylinder block rigidity is higher, improve engine operation reliability and longer the engine using life.

Fuel injection pump

PS8500 injection pump, only 415 series is PS 7100

Advantage--PS8500 is the first line product in engine field of China market, fuel consumption, torque and displacement better than others.                                   

The injector is by U.K DELPHL tech. better pulverization and sufficient burning.

Connecting rod

By EuroIII standard

Advantage-- Adopts the standard EuroIII of RICHARDO, U.K., strengthening and upgrading the current connecting rod.

Starter

Adopts deceleration type starter

Advantage-- volume and weight reduce 1/3 than others. Big torque ensured when starting at lower temperature and no tooth breaking, adopts advanced tech of slow engagement sealing system, IP56 military vehicle structure, extends using life.

Customers feedback

MAN series engines no maintain within 15000 hours, we try to up to 50000hours.

Parts advantage

Short delivery time, usually dispatch can be within15-20 days, the parts price is lower 1/4-1/3 than others.
