Study Notes
Cylinder Arrangement
- Cylinder arrangement refers to the position of the cylinders in relation to the crankshaft.
- Four basic cylinder arrangements include inline, V-type, W-type, and opposed.
Engine Configuration
- Inline engines line up all cylinders in a single row.
- W-type engines consist of two cylinder banks forming a narrow "V" with offset cylinders.
- Opposed engines have cylinders lying flat on either side of the crankshaft.
Cylinder Count and Engine Performance
- Typical car and truck engines have 4, 6, or 8 cylinders.
- More cylinders generally increase engine smoothness and power.
- An 8-cylinder engine produces twice the number of power strokes per crank revolution compared to a 4-cylinder engine.
Cylinder Numbering
- Engine manufacturers number each cylinder to aid technicians during repairs.
- Cylinder numbers are often stamped on connecting rods or cast into the intake manifold.
Cooling Systems
- Liquid cooling systems surround the cylinder with coolant to transfer combustion heat away from the engine block.
- Air-cooled engines use air circulation over cooling fins on cylinders to prevent overheating and are seldom used in passenger cars.
Fuel Types
- Engines can be classified by the fuel they burn, including liquefied petroleum gas, gasohol, and pure alcohol.
- The two most common fuels for vehicles are gasoline and diesel.
Ignition Types
- Spark ignition engines use an electric arc at the spark plug to ignite fuel.
- Compression ignition engines compress air in the combustion chamber until hot enough to ignite fuel.
- Gasoline engines utilize spark ignition, while diesel engines operate with compression ignition.
Engine Valve Configurations
- L-head engines have both intake and exhaust valves in the block, while I-head engines have both in the cylinder head.
- There are two basic locations for the engine camshaft: in the block and in the cylinder head.
- Cam-in-block engines use push rods to transfer motion to the rocker arms, whereas overhead cam engines position the camshaft in the cylinder head.
Camshaft Types
- Single overhead cam engines have one camshaft per cylinder head.
- Dual overhead cam arrangements are commonly found in engines with four-valve combustion chambers.
Combustion Chamber Designs
- Four types of combustion chamber designs include pancake, wedge, hemispherical, and pent-roof.
- Pancake combustion chambers feature valve heads almost parallel to the piston.
- Hemispherical combustion chambers place the spark plug near the center.
- Swirl combustion chambers are designed to spin the air-fuel mixture as it enters from the intake port.
- Four-valve combustion chambers enhance flow efficiency with additional valves.
- Three-valve combustion chambers consist of 2 intake valves and 1 exhaust valve.
