康明斯 QSX15-C535 Diesel motor

Cummins diesel engine.The diesel engine hasthe highest thermal efficiency (engineefficiency) of any practical internal or externalcombustion engine due to its very highexpansion ratio and inherent lean burn whichenables heat dissipation by the excess air. Asmall efficiency loss is also avoided comparedto two-stroke non-direct-injection gasolineengines since unburned fuel is not present atvalve overlap and therefore no fuel goesdirectly from the intake/injection to theexhaust. Low-speed diesel engines (as used inships and other applications where overallengine weight is relatively unimportant) canhave a thermal efficiency that exceeds 50%.For more details and requests, please contactsalesperson Frank wechat/whatsapp+8615265755218
