ABSTRACT:
The design and construction of present midsupported liner and multipiece block engines has caused increased manufacturing cost and reduced engine reliability. The present invention overcomes these engine construction problems by using an engine structure comprises the bottom block portion, cylinder head, top block portion positioned between the bottom block portion and the cylinder head and midsupported cylinder liner. The cylinder liner and the top block portion form an annular space therebetween for cooling the combustion area. The top block portion is structurally designed to have a simple profile which is easy to cast, core and machine thereby reducing overall costs. The predetermined height of the top block portion "H.sub.1 " and the predetermined height of the annular space "H.sub.2 " combined with the ability to vary both or either further simplifies the manufacturing of a variety of engines having a variety of output horsepower and yet retain a high efficiency level. The top block portion concept eliminates bottom bores and reduces high stresses in the components within the engine thereby increasing life and reducing down time.
