Copyright Goodheart-Willcox Co., Inc. 220 Critical Thinking Questions 1. Research laser ignition system technology for internal combustion engines. What is the basic design of a laser ignition system? What are the advantages and disadvantages compared to a spark ignition system? Do you think this technology will eventually replace the electronic spark ignition system currently used in modern vehicles? Why or why not? 2. Examine the development of the automotive ignition system from the days of the first internal combustion engine vehicles to today’s late-model vehicles. What factors have driven the continued development of the ignition system? Over the years, what were the major reasons for the removal and/or addition of certain parts to the overall ignition system design? Have any parts remained relatively unchanged in their design or operation? What are the three biggest benefits of today’s ignition systems compared to the ignition systems used in the past?
