Abstract

Although the various operating conditions of a small gasoline engine are easily discussed, they are not so easily demonstrable. The teaching aid to be constructed will be used to demonstrate the relationships between throttle-controlled engine speed, fuel and air flow, volumetric efficiency, combustion efficiency, fuel-air ratio, exhaust system temperature, and pressure conditions existing in the air induction system at various choke positions of a four cycle single cylinder engine.A review of literature related to reciprocating internal combustion engines reveals a lack of information dealing with the relationship between throttle-controlled engine speed and the above listed factors of engine operation--especially for small gasoline engines. The project presented in this paper was designed to help fill in some of these information gaps by providing a vehicle, in the form of a four cycle small gasoline engine, for demonstrating these relationships and assertaining information for graphic illustration of the various operating aspects of a particular engine under the conditions which follow.
