I knew we had several internal combustion engines in our family’s possession, but the total count is impressive.

• one 6-cyl 170hp, big yellow car

• one 4-cyl 130hp, little brown car

• two 6-cyl 250hp, airplane

• one 1-cyl 6hp, airplane tow widget

• one 1-cyl 2hp, portable generator

• one 1-cyl 8hp, snowblower

• one 1-cyl 6hp, lawnmower

Their upkeep costs scale superlinearly compared to their horsepower, but so does their entertainment value!
