Very high radial compressive stresses can develop in these LHR heads as a result of constrained expansion of the high-temperature fire deck area inside the cylinder liner.
Operational life is reduced unless care is taken in material selection and design.
The size followed from a strict meching criteria. In turn, this will provide diesel engines with greater reliability, lower fuel consumption, and lower maintenance and operation costs. In addition, the volume requiring armor protection will be reduced with consistent additional savings. Because this analysis was done on a generic head, any future diesel-powered fighting vehicle could benefit from LHR technology. All rights reserved.
