Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the torque amplification?Increases leverage on the crankshaft during the power stroke, enhancing torque output
2. What is the friction reduction?Decreases lateral thrust against cylinder walls, potentially reducing wear and improving efficiency
3. What is a desaxe engine?A desaxe engine has the cylinder’s center shifted a little from the crankshaft’s center, making the engine "wobbly" but smarter.
4. Why does the offset help the engine?The shift makes the connecting rod act like a longer lever, giving more torque and reducing side‑thrust, which lowers friction and wear.

Bore Axis: The central longitudinal axis of the cylinder bore.
Crankshaft Journal: The cylindrical surface on the crankshaft that rotates within the connecting rod bearing.
Connecting Rod: The linkage mechanism connecting the piston to the crankshaft.
Thermodynamic Efficiency: The efficiency with which an engine converts heat energy from combustion into mechanical work.
