The two-stroke engine is an engineering marvel that has been incorporated into many aspects of modern-day life. While many seek to eliminate the two-stroke, others seek to revive this simple and effective power plant, aiming to make it more environmentally friendly and fuel-efficient. If successful, improvements could be far-reaching and transformative. Students can be introduced to this topic, learning: design principles; the implications of this technology on society; how to build, repair, modify an engine; create solutions; and ultimately make an informed decision as to the proper use of the two-stroke engine.
