Even Firing Engine Cars
An even firing engine is an internal combustion engine in which the firing interval between each cylinder is equal to the angle of crankshaft rotation between each cylinder. This results in a smooth and even power delivery, and it also helps to reduce vibration. Even firing engines are often used in luxury cars and sports cars, but they can also be found in some economy cars.
There are two main types of even firing engines: V-type engines and inline engines. V-type engines have two banks of cylinders that are arranged in a V-shape, while inline engines have all of their cylinders arranged in a straight line.
V-Type Even Firing Engines
V-type even firing engines are the most common type of even firing engine. They are popular because they are relatively compact and lightweight, and they can be easily packaged in a variety of vehicle designs. V-type engines are also known for their smooth and powerful operation.
The firing order of a V-type engine is determined by the angle between the two banks of cylinders. The most common firing order for a V-type engine is 1-8-4-3-6-5-7-2, which means that the cylinders fire in the following order:
- Cylinder 1
- Cylinder 8
- Cylinder 4
- Cylinder 3
- Cylinder 6
- Cylinder 5
- Cylinder 7
- Cylinder 2
This firing order results in a smooth and even power delivery, and it also helps to reduce vibration.
Inline Even Firing Engines
Inline even firing engines are less common than V-type engines, but they are still used in some vehicles. Inline engines are popular because they are relatively simple to design and build, and they are also very compact. Inline engines are also known for their smooth and quiet operation.
The firing order of an inline engine is determined by the number of cylinders in the engine. The most common firing order for a 4-cylinder inline engine is 1-3-4-2, which means that the cylinders fire in the following order:
- Cylinder 1
- Cylinder 3
- Cylinder 4
- Cylinder 2
This firing order results in a smooth and even power delivery, and it also helps to reduce vibration.
Advantages of Even Firing Engines
There are a number of advantages to using an even firing engine. These advantages include:
- Smooth and even power delivery
- Reduced vibration
- Compact and lightweight design
- Easy to package in a variety of vehicle designs
- Reduced emissions
- Improved fuel economy
Disadvantages of Even Firing Engines
There are also some disadvantages to using an even firing engine. These disadvantages include:
- More complex to design and build than odd firing engines
- Can be more expensive to manufacture than odd firing engines
- May not be as efficient as odd firing engines at low rpms
Conclusion
Even firing engines are a popular choice for a variety of vehicles. They offer a number of advantages, including smooth and even power delivery, reduced vibration, and compact and lightweight design. However, even firing engines can also be more complex and expensive to design and build than odd firing engines.
