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…

Chapter 3: Induction & Exhaust Systems › Basic Carburetor Induction System › Induction System Icing
Induction System Icing A short discussion concerning the formation and location of induction system ice is helpful, even though a technician is not normally concerned with operations that occur when the aircraft is in flight. [Figure 3-7] Technicians should ... know something about induction system icing because of its effect on engine performance and troubleshooting. Even when an inspection shows that everything is in proper working order and the engine performs perfectly on the ground, induction system ice can cause…
