The gasoline spark ignition engine and the diesel compression ignition engine are both examples of __ engines. a. Rotary b. Internal combustion c. External combustion d. Two-stroke

## Step 1<br />The problem is asking us to identify the type of engines that both the gasoline spark ignition engine and the diesel compression ignition engine fall under. <br /><br />## Step 2<br />The gasoline spark ignition engine and the diesel compression ignition engine are both examples of internal combustion engines. This is because the combustion process in these engines occurs within the cylinders of the engine. <br /><br />## Step 3<br />In the gasoline spark ignition engine, a spark plug ignites the air-fuel mixture in the cylinder. This causes a rapid expansion of gas, which pushes the piston down. <br /><br />## Step 4<br />In the diesel compression ignition engine, the air is compressed to a high temperature and pressure, and the fuel is injected into the cylinder. The heat from the compressed air ignites the fuel, causing a rapid expansion of gas that pushes the piston down. <br /><br />## Step 5<br />This is different from external combustion engines, where the combustion process occurs outside the engine, such as in a steam engine. <br /><br />## Step 6<br />Rotary engines are a type of internal combustion engine, but they are not the only type of internal combustion engine. <br /><br />## Step 7<br />Two-stroke engines are a type of internal combustion engine, but they are not the only type of internal combustion engine.
