What is the difference between a three-cylinder car and a four-cylinder car?
1 Answers
The differences between a three-cylinder car and a four-cylinder car are: 1. Different number of cylinders: The engine of a three-cylinder car has three cylinders; the engine of a four-cylinder car has four cylinders. 2. Different ignition intervals: The ignition sequence of a three-cylinder car is 1, 3, 2, with an ignition interval of 240 degrees; the ignition sequence of a four-cylinder car is 1, 3, 4, 2, with an ignition interval of 180 degrees. Common cylinder numbers for car engines are 3, 4, 5, 6, 8, 10, and 12 cylinders. Engines with a displacement of less than 1 liter usually use three-cylinder engines, 1 to 2.5 liters generally use four-cylinder engines, around 3 liters usually use six-cylinder engines, around 4 liters use eight-cylinder engines, and above 5.5 liters use twelve-cylinder engines.
