Overheating Investigation on 5-Cylinder Engine

Overheating is a common automotive engine problem. It is often the result of coolant loss or low coolant level which may be due to leaks in hoses, radiator or even engine itself.

An issue related to the engine cylinder head critical metal temperature transmitted to driver's temperature gauge as red zone was seen on 5-cylinder light duty diesel engine during confirmation prototype phase tests. ATI recordings showed that engine coolant temperature was rising to red zone of temperature gauge during acceleration.

Engine cylinder head critical metal temperature and coolant pressure measurements across the thermostat housing were conducted during the overheating experimental investigation and measurements were compared with 5-cylinder engine cooling system Flowmaster analysis.
