With the increase of combustion loading and the trend to reduce engine size, there is a need for thinner but stronger wet cylinder liners. While most of the current cylinder liners are made of gray cast iron, due to its good tribological behavior, machinability performance and competitive price, alternative casting materials like compact graphite iron, ductile iron and even steel are being considered to cover the future engine demands. In this paper, a new ductile iron (DI) cast material for wet cylinder liners is presented. The material has about 60 and 70% higher limits respectively for tensile stress and fatigue resistance as compared to conventional gray cast irons, but without penalty on the tribological properties. There is also a potential improvement to avoid cavitation on the outside surface due to its higher young modulus, which also equates to a higher stiffness. The tested cylinder liners were induction hardened on the running surface and a slide hone process was used to improve wear and scuffing resistance. The liners were tested in a HDD engine with PCP of 245 bar and showed similar wear as observed with conventional cylinder liners of gray cast iron material. The DI cylinder liners were also tested in an abusive scuffing engine test without any concern. The improved mechanical properties of the described new DI material introduce possibilities to reduce liner wall thickness or increase specific output. The preliminary evaluation in this paper showed that this new material is feasible for HDD diesel engines with PCP up to 250 bar. In cases that the customer needs to increase the bore diameter for output reasons there is the potential to reduce the liner wall thickness up to 25% based on high mechanical properties (UTS, Young Modulus and fatigue strength). In both cases, it’s recommended a FEA analysis to support the new component design.

The nature and mechanism of cracking in cast iron diesel cylinder heads arising from the differential thermal strains which occur in service are reviewed. The results of experimental work with test apparatus simulating the conditions in a cylinder head are presented, illustrating the importance of controlling the boiling conditions of the water at the cooling face of the flame deck. It is concluded that cylinder head temperatures, and therefore the danger of cracking, can be successfully reduced by increasing the flow of cooling water over critical areas by some form of directed flow.

Erosion Protection

Ultrasonic vibratory cavitation erosion tests were carried out on studying the cavitation erosion protection performance of different type of heavy-duty engine coolants for cast iron material of wet sleeve cylinder liners. The influence of coolant type, freezing point, corrosion inhibitor content and test duration on anti-cavitation performance were analysed. The experimental results showed that the anti-cavitation erosion performance of organic acid type heavy-duty engine coolants were better than the inorganic salt type heavy-duty engine coolants. For the same formulation coolant, increasing the content of ethylene glycol or corrosion inhibitor can improve the anti-cavitation erosion performance. With the extension of ultrasonic vibration test time, the anti-cavitation erosion protection performance for cast iron was reduced.
