What statement is true concerning diesel engines, such as those used for main propulsion and auxiliary power on tugboats?

🔍 Key Concepts

• Basic engine motion types: reciprocating vs rotary • Where the fuel actually burns: internal vs external combustion • How diesel fuel is ignited compared to gasoline engines

💭 Think About

• Ask yourself: In a diesel, do parts move back-and-forth, rotate, or both — and what is the primary motion type used to describe the engine? • Does a diesel burn its fuel inside the cylinder where the piston moves, or somewhere outside and then transfer heat in? • What specifically causes ignition in a diesel: a spark plug, or very high compression and temperature of the air-fuel mixture?

✅ Before You Answer

• Identify whether a diesel is classified as reciprocating or rotary for exam purposes. • Decide if a diesel is an internal or external combustion engine based on where combustion takes place. • Confirm whether diesel ignition relies on heat from compression or electric spark.

What statement is true concerning diesel engines, such as those used for main propulsion and auxiliary power on tugboats?

Diesel engines are rotary, internal combustion engines using the heat of compression to achieve ignition.

Diesel engines are reciprocating, external combustion engines using the heat of compression to achieve ignition.

Diesel engines are reciprocating, internal combustion engines using an electric spark to achieve ignition.

Diesel engines are reciprocating, internal combustion engines using the heat of compression to achieve ignition.
