Variable Cycle Internal Combustion Engine

 

Abstract
The purpose of this design project is to produce a prototype of a cam-less engine, capable of shifting between four and six stroke operations based on the temperature. The motivation behind this design was to produce an engine capable of scavenging waste thermal energy by utilizing six stroke capabilities, while retaining the benefits of a conventional four stroke. This is accomplished by utilizing a conventional, four stroke internal combustion engine. The design involves using an electronically controlled valve system that distributes necessary combustion materials at the correct timing for each operation. This program is coded and utilizes the Arduino system to ensure that proper measurements can be taken and relayed to the linear actuators. Additional changes to the engine were made as well to integrate a water injector capable of properly distributing the correct amount of water per cycle. Community Benefit: A positive impact on the community and the environment as a result of the engine’s reduced reliance on fossil fuels through energy conservation. In addition, it is easily adaptable to the mainstream market.
