engines that have a complete cylinder baffling system that covers the cylinder heads. Its purpose is to force the air to circulate around and through the baffle system. Inspect the cowl panels during each regular engine and aircraft inspection. Removing…

Chapter 6: Lubrication & Cooling Systems › Engine Cooling Systems › Reciprocating Engine Cooling System Maintenance
Reciprocating Engine Cooling System Maintenance The engine cooling system of most reciprocating engines usually consists of the engine cowling, cylinder baffles, cylinder fins, and some use a type of cowl flaps. In addition to these major units, there are also ... some temperature-indicating systems, such as cylinder head temperature, oil temperature, and exhaust gas temperature. The cowling performs two functions: 1. It streamlines the bulky engine to reduce drag. 2. It forms an envelope around the engine that forces…

Chapter 6: Lubrication & Cooling Systems › Engine Cooling Systems › Reciprocating Engine Cooling Systems
Engine Cooling Systems Excessive heat is always undesirable in both reciprocating and turbine aircraft engines. If means were not available for its control or elimination, major damage or complete engine failure would occur. Although the vast majority of reciprocating engines ... cooled, some diesel liquid-cooled engines are being made available for light aircraft. [Figure 6-49] In a liquid-cooled engine, around the cylinder are water jackets, in which liquid coolant is circulated and the coolant takes away the excess…

Chapter 3: Induction & Exhaust Systems › Reciprocating Engine Induction Systems › Supercharged Induction Systems
Induction System Troubleshooting Figure 3-8 provides a general guide to the most common induction system troubles. Supercharged Induction Systems Since aircraft operate at altitudes where the air pressure is lower, it is useful to provide a system for compressing ... fuel mixture. Some systems are used to normalize the air pressure entering the engine. These systems are used to regain the air pressure lost by the increase in altitude. This type of system is not a ground boost system…
