AJAX ECIDI diesel engine

The AJAX ECIDI (from Electronic Control Indirect Injection) series is a family of four-stroke diesel-powered internal combustion engines. The family was designed and produced by AJAX, a joint venture between Gorganstien Motor Works and Murdovsky Motors. The AJAX ECIDI was primarily water-cooled, but air cooled variants also existed. V engines featured overhead camshafts and 4 valves per cylinder. However, the inline configuration ECIDI engines can be supplied as sidevalve units with a reverse-flow cylinder head, something exclusive to the inline configuration and absent from the V configuration ECIDI. Inline engines also featured an overhead valve arrangement despite not being crossflow engines.
