Different "Inline Engine" Configurations Explained | [I2 to I8]

Introduction:
The straight or inline engine is an internal combustion engine with all cylinders aligned in one row and having no offset. In this engine construction, the cylinders are placed in a straight line. The inline engine can have up to 2, 3, 4, 5, 6, or 8 cylinders.

Inline engines are smaller in overall physical dimensions than designs such as the radial and can be mounted in any direction. These engines are very common in vehicles with an engine capacity of up to 3 liters. Although, the manufacturers term an inline engine with four cylinders as an Inline-4 engine. They usually denote it by I4 or L4 in a car’s nomenclature.

1) Straight-Twin Engine: A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine with cylinders arranged in a line along with a common crankshaft.

2) Straight-3 Engine: A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along with a common crankshaft.

3) Straight-4 engine: An inline-four cylinder (also known as an I-4 or straight-four) engine is a very popular choice for today’s economy vehicles as the simple design allows for both efficiency and perfect primary balance. In an I-4 engine, all 4 cylinders are mounted in a straight line along with a single crankshaft and oriented in an inclined or vertical plane

4) Straight-5 Engine: The straight-five or inline-five engine is an IC engine with five cylinders aligned in one row, sharing a single-engine block and crankcase. The justification for a five-cylinder engine is that it is compact as an inline-four and almost as smooth as a straight-six engine.

5) Straight-6 Engine: The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is an internal combustion engine with six cylinders mounted in a straight line along the crankcase with all the pistons driving a common crankshaft (straight engine).

6) Straight-8 Engines: The straight-eight engine or inline-eight engine (often abbreviated as I8 or L8) is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase.
