Understanding The Basics Of Stroker Engines

By Matthew Campbell


The stroke and bore of an engine are used to calculate displacement. The better your cylinder diameter (bore), the better the horsepower you get. A better stroke on the other hand, provides increased torque. For you to understand aspects around stroker engines, you must first get familiar with how the engine functions as a whole.

The normal engine of car has over 350 moving parts. The most vital ones are the cylinders, spark plugs, pistons, fuel jets and crankshaft. You will find four pistons in the typical four-cylinder, four-stroke engine. Each of the pistons helps to complete a cycle of four different strokes. Strokes are the motion through which a piston crosses the diameter of a cylinder in whichever direction.

Here is a clear description of how a piston functions within its cylinder in a petrol engine. For a stroke to start, the piston will be at the top dead middle of a cylinder. It will then descent forming volume and a combination of air from the intake valves and gasoline. The second stroke is when the piston rises from the bottom dead center and causes compression of the gasoline and air mixture in the cylinder head.

The third stroke begins with the piston on top of the dead center of a cylinder. The functions of the spark plugs are at this point crucial and they ignite the compacted gasoline, creating a lot of pressure that makes the pistons descend once more. After the gasoline is burnt, the material left behind is freed through a separate valve and the piston can now continue to get to the dead centers top. It is the functions of the four pistons that power a vehicle engine.

A stroker engine is designed to increase the stroke of an engine or rather the distance that each piston covers. Creating more distance will in return accelerate the rotating speed of the crankshaft as well as the connecting rod, generating better torque. This will also better acceleration causing the wheels of a car to rotate faster.

When a car has better torque, it can speed up within a shorter duration. It is however crucial to understand that this will not better its maximum speed or power. A vehicle with better torque can in the beginning lead during a race, although the car with better horsepower will catch up and remain in front within no time.

To increase the distance covered by the pistons, there are various strategies that could be used. First, the block deck height can be increased. This is an expensive option and you need to acquire an aftermarket block deck that is specially designed for a stroker engine. You can also choose to increase the length of the rod linked to a piston or simply opt to buy a stroker kit.

There are more than a few pros allied with having a stroker engine. First, you will enjoy better placement and more torque. You will also achieve top speed within a shorter while. It will not be necessary for you to down shift if you want to accelerate from lower speed.
