A. Type of fuel used:
1. Diesel engines: These engines use diesel fuel, which is a type of heavy fuel oil. They are commonly used in large ships due to their high efficiency and reliability.
2. Gasoline engines: These engines use gasoline as fuel. They are typically found in smaller vessels, such as pleasure boats and small fishing boats.
3. Dual-fuel engines: These engines can operate on both diesel and natural gas. They provide flexibility in fuel choice and can be more environmentally friendly.
B. Cycle of operation:
1. Two-stroke engines: These engines complete one power cycle in two strokes of the piston (one upstroke and one downstroke). They are simpler in design and have a higher power-to-weight ratio.
2. Four-stroke engines: These engines complete one power cycle in four strokes of the piston (intake, compression, power, and exhaust). They are more fuel-efficient and produce less pollution compared to two-stroke engines.
C. Number of strokes per cycle:
1. Two-stroke engines: These engines have two strokes per cycle, as mentioned above.
2. Four-stroke engines: These engines have four strokes per cycle, as mentioned above.
D. Types of ignition:
1. Spark-ignition engines: These engines use spark plugs to ignite the air-fuel mixture in the combustion chamber. They are commonly used in gasoline engines.
2. Compression-ignition engines: These engines rely on the heat generated by compressing the air in the combustion chamber to ignite the fuel. They are commonly used in diesel engines.
E. Number of cylinders:
1. Single-cylinder engines: These engines have only one cylinder. They are typically found in small boats or auxiliary engines.
2. Multi-cylinder engines: These engines have multiple cylinders, such as 2-cylinder, 4-cylinder, 6-cylinder, or even more. The number of cylinders affects the engine's power output and smoothness of operation.
F. Cooling:
1. Air-cooled engines: These engines rely on air circulation to dissipate heat and keep the engine cool. They are commonly used in smaller boats or engines with lower power requirements.
2. Water-cooled engines: These engines use a cooling system that circulates water or a mixture of water and coolant to remove heat from the engine. They are more efficient in dissipating heat and are commonly used in larger ships.
1. Diesel engines: These engines use diesel fuel, which is a type of heavy fuel oil. They are commonly used in large ships due to their high efficiency and reliability.
