Water jacket

Water jacket

A water jacket is a component of an engine that is used for cooling purposes. It is responsible for carrying away excess heat and maintaining nearly constant temperature conditions. Water is supplied through the cylinder head and engine block via the water jackets to cool the engine. Water cooling is achieved by circulating cool (but not chilled) water through an integral water jacket.From: Automotive Technician Training: Theory [2019], Emission characteristics of a CI engine using preheated CNSL oil & diesel blends and ethanol fumigation [2020], Tutorials in Radiotherapy Physics [2019], Illustrated Encyclopedia of Building Services [2019]

Water-cooled engines work on the principle of surrounding the hot areas inside the engine with a water jacket. The water takes on heat from the engine and, as it circulates through the radiator, gives it off to atmosphere. The heat concentration around the top of the engine means a water pump is needed to ensure proper circulation.

Figure 1 shows Experimental setup for the ethanol fumigation technique. It always runs at the rated speed because of its coupling with Eddy current dynamometer. The experiments were conducted using Kirloskar AV-1 single cylinder four stroke diesel with vertical water cooled engine with the parameters as shown in Table 1. The water is supplied through the cylinder head and engine block through the water jackets in order to cool the engine.
