At Rotary Club of Ann Arbor North Luncheon on January 3, 2019, Don Patterson was the keynote speaker. Don's topic was how automobiles work.
 
He talked about different type of engines and what engines can fit in different car frames. He showed the club, a small engine, a catalytic converter part and a fuel injector and taught us how they work.
 
Don talked about and showed a video on engine combustion. Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture.  In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work. The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the power train, this motion drives the vehicle’s wheels.
 
The club also had two special guests at the luncheon. Take a look at they're photos below.
