What part of an internal-combustion engine turns linear motion into rotational motion?
Heat engines are machines that burn some type of fuel to produce heat, then convert the heat energy into mechanical energy. Most heat engines burn gasoline to produce heat. In addition to the fuel, large amounts of air are needed for combusion. Two types of heat engines: (steam engines – 1 min) #2 Questions 1. External-Combustion Engine: Fuel is burned outside the engine. Turbine 2. Internal-Combustion Engine: Fuel is burned inside the engine. Four-Cycle (strokes): • Intake • Compression • Power • Exhaust Two-Cycle (strokes): • Intake and Power • Compression and Exhaust Diesel Engine: Fuel is compressed to a point where the temperature is high enough for spontaneous combustion. Any volunteers may ask the science facilitator for tools and remove the #1 piston from the Chevy 350 V-8 engine in the classroom. Concept Understanding: • Write at least one paragraph explaining why a two-cycle engine is less efficient than a four-cycle engine. • Write at least one paragraph explaining why two-c
