所设计的M453C和M35L扩大了KruppMaK四冲程发动机的规划,它已和M282/M332, M452/M453,M35,M551/M552和M601组成系列发动机,功率范围为780～9900kW,转速从1000r/min降低到400r/min。 M453C是近年研制的,缸径为320mm,近两年的记载用于陆用、船用装置已超过2200台。由于选用了适中的性能参数,使发动机工作可靠(活塞平均速度 8.4m/s,平均有效压力19.7bar),同时发动机机体和气缸盖都采用高级球墨铸铁。长的活塞行程使其获得满意的燃烧室,虽然压缩比高,但它有利于烧重油,低的燃油消耗率为131g/(ps·h),从动力学观点来说,有利于爆发压力和快速喷油,使发动机运转平稳柔和。 M35L还在试验,它是原M35机缸径350mm的变型长冲程发动机。设计目标是零件的最大可靠性和经济性。应用的原则类似于M453C发动机。
The M453C and M35L are designed to expand the KruppMaK four-stroke engine program and comprise a series of engines with M282 / M332, M452 / M453, M35, M551 / M552 and M601 with a power range of 780-9900 kW and a speed reduction from 1000 r / min To 400r / min. M453C is developed in recent years, bore 320mm, nearly two years of records for land use, marine installations have more than 2,200 units. Due to the selection of moderate performance parameters, the engine work reliably (average piston speed of 8.4m / s, the average effective pressure of 19.7bar), while the engine body and cylinder head are made of advanced ductile iron. Long piston stroke to obtain a satisfactory combustion chamber, although the compression ratio is high, but it is conducive to burn heavy oil, low fuel consumption rate of 131g / (ps · h), from the kinetic point of view, is conducive to the outbreak of pressure and Fast fuel injection, the engine running smooth and soft. M35L still test, it is the original M35 machine bore 350mm long variant stroke engine. The design goal is the maximum reliability and economy of the part. The principle of application is similar to the M453C engine.
