Dodge 3.6 Firing Order (How to Understand The Engine Cylinder Number?)

Each brand of engine comes up with a specific unique firing sequence. And each engine configuration has its own different sequence of events. That’s why the Ram 3.6L engine firing order will be different from the Ford 5.4 Triton, Chevrolet 350, or another popular engine. 

So, what is the correct Dodge 3.6 Firing Order?

What is Engine Firing Order?

Firing line order refers to the pattern through which individual cylinders of an internal-combustion engine get sparked. Basically, it’s the correct operating pattern of the gasoline engine’s spark plugs or the diesel engine’s fuel injection sequence. 

The cylinders of an engine are not ignited in the traditional 1-2-3-4-5-6 pattern. It may lead to damage or breakage of the crankshaft. For this reason, manufacturers often reorder the combustion process to strike an excellent power-to-weight ratio in the motor. 

Engine firing order refers to the specific order in which an engine’s cylinders produce and distribute power. For inline engines, the cylinder closest to the radiator at the front is always considered to be cylinder 1. Consequently, the next in line is referred to as 2, and thus on.

The total number of cylinders in an engine sets the order. Nonetheless, it may be different from one engine to the next due to design considerations. Most inline engines have the cylinder closest to the radiator be numbered 1.

After that comes cylinder 2, and so forth. However, cylinder numbers in V-engines are sometimes assigned differently. In most cases, though, it will be the first on the right side of the first bank.

Nowadays, most modern vehicles come with 4 or 6 cylinders. Engine’s crankpins with 4 cylinders are set at an angle of 90 degrees from one another. Usually, manufacturers often apply either the 1-2-4-3 or 1-3-4-2 sequence of firing. And a horizontally-opposed 4-cylinder motor follows the firing order of 1-4-5-3. 

On the other hand, the firing order of an inline-6 cylinder engine is generally 1-5-3-6-2-4, 1-3-2-6-4-5, 1-2-4-6-5-3, or 1-2-4-6-5-3. 

Why Is Firing Order Important?

In an internal combustion engine with several cylinders, the firing order sets the sequence in which the cylinders give power to the engine. When constructing an engine, selecting the correct firing sequence is essential for reducing vibration and producing smooth operation for a lasting engine load-bearing capacity and rider comfort.

The proper selection of firing order also has a significant impact on the design of the crankshaft.Achieving balance and minimizing vibration as much as could be humanly possible are the major goals of designing a firing sequence. 

As the cylinders can’t all fire at once, the firing sequence guarantees a consistent power supply. For optimal performance, a piston’s spark plug has to be inserted at precisely the right moment in time as the piston rotates.

The power supply will be jerky if it ignites at the same time. Moreover, incorrect combustion caused by a wrong firing sequence directly affects an engine’s efficiency. Efficiency in fuel combustion may be maximized by using the correct firing sequence.

Guide To Firing Orders of Engine 

How manufacturers use the distributor to place the spark plug wires helps to attain the proper firing order. The ECU (Engine Control Unit) is responsible for ensuring that a modern engine, including an engine-management system with direct ignition, uses the appropriate firing sequence.

Particularly on distributor-equipped automobiles, most often, the firing order takes place on the intake manifold, valve covers, or cylinder head. 

Regarding the discussion of automobiles, if you see from the point of view of the driver’s seat, the vehicle’s leftward faces the driver’s left side. When speaking about engines, the front part is the place for locating the accessory pulleys like the water pump and alternator. And the flywheel, through which the transmission connects with the motors, is set on the back engine. 

However, most manufacturers position the front engine as forward-faced in FWD (Front Wheel Drive) vehicles with lengthwise arranged engines. Although some others, such as Citron, Saab, and Renault, occasionally place the engine backward-faced with the number 1 pointing to the firewall. 

Based on different engine layouts, the cylinder numbering also differs. For example, the spark plugs in straight engines come from the engine’s front toward the rear, starting with number 1. Whereas in a radial engine, the firing sequence has to adhere to a specific pattern since, for the firing impulses, it’s a must to follow the crank throws motion at the time of rotation. 

But the firing orders of inline engines might differ slightly. Although the firing orders of inline engines might differ slightly, most of the firing orders are organized in such a way that cylinders firing get equally spaced around the crankshaft.

In V engines, generally, manufacturers maintain the initial forward cylinder as number 1. But others place it so that the engine’s side is 1-2-3-4 and the other side is 5-6-7-8. But other manufacturers number the engine’s cylinders from the front towards the back along with the crankshaft. Therefore, one side’s firing sequence is 1-3-5-7, and 2-4-6-8 is for another side. 

What Is The Dodge 3.6 Firing Order?

The Dodge 3.6 liter V6 engine is the only one whose cylinders follow a firing order in the traditional 1-2-3-4-5-6 pattern. The 305-horsepower, the 3.6-liter V6 engine, is unique because it uses sequential ignition. The sequence of shots is 1-2-3-4-5-6.

This implies that the engine’s ignition sequence goes as follows: cylinder-1, cylinder-2, and cylinder-3. It proceeds from cylinder-4 to cylinder-5 and finally to cylinder-6.

Furthermore, other manufacturers’ V6 engines employ a different ignition sequence. This occurs due to the fact that different manufacturers implement different firing patterns for particular engines.

01. Dodge Ram 1500 3.6L Firing Order 

1-2-3-4-5-6 is the firing sequence of a 1500 Dodge Ram with a 3.6-liter engine. The cylinders’ configuration is as follows: Bank of the vehicle occupied by the passenger, from front to back: 1, 3, and 5

Left-hand, front-to-back: 2 -4 -6

02. Dodge Charger 3.6 Firing Order 

Dodge Charger V6 3.6 Liter engine’s firing pattern is 1-2-3-4-5-6. And, the cylinders are configured as 2-4-6 on the left bank and 1-3-5 on the right bank. 

03. Dodge Caravan 3.6 firing order 

The firing order of the 2012 Dodge Caravan 3.6L is 1-2-3-4-5-6. The radiator side’s front bank firing order is 2-4-6, and 1-3-5 is for the rear bank. The firing order of other model years of Dodge Caravan and Dodge Grand Caravan is equipped with this same order pattern. 

2014 Dodge Caravan 3.6 firing order is 1-2-3-4-5-6. The proper bank ignition order is 1-3-5, and the left bank is 2-4-6. 

People Also Ask

How do I know if my firing order is wrong?

If the firing order goes wrong, the vehicle will still get started, but it won’t function properly. As a result of the incorrect firing sequence, the spark can be supplied to the cylinder before the fuel and air have been appropriately mixed or compressed to the accurate level. In the worst possible scenario, you’ll notice that the ignition key will not cause the engine to start. 

Can I change the engine firing order?

You are unable to adjust the firing sequence since it has been predetermined inside the layout of the interaction between the camshaft and crankshaft. The standard firing sequence for a 4-stroke inline engine is 1, 2, 4, 3. However, the inverse firing order of 1,3,4.2 is also possible.

How to know if my engine’s firing order needs to be corrected?

There are a few symptoms of a wrong-firing command. When the engine’s cylinders are fired in the incorrect sequence, you may not experience any immediate effects, but the vehicle won’t operate right.

Such a situation occurs when the spark is sent to the cylinder despite the absence of an air-fuel mixture or improper compression of the mix. The worst-case situation is that twisting the key won’t help to spark out the engine.

What is a 3-stroke engine’s firing pattern?

An internal combustion 3-stroke engine uses the first piston’s single cycle and the second piston’s single stroke within the confines of a single cylinder to execute the entire ignition process of intake, exhaust, compressing, combustion, and expansion during a single crankshaft rotation. The ideal firing sequence of a 3-stroke engine is 1-3-2.  

What is an 8-stroke engine’s pattern of firing?

Considering several facts such as engine cooling, engine vibrations, back pressure development, engine balance, and power flow, manufacturers set the best firing order for 8-cylinder engines, such as:

  • 1-8-4-3-6-5-7-2 (318 Dodge Motor)
  • 1-8-4-3-6-5-7-2 (V8 4.7L Dodge Engine)
  • 1-8-4-3-6-5-7-2 (V-8 5.9 L Chrysler Dodge Hemi Engine)
  • 1-8-4-3-6-5-7-2 (426 Hemi engine)
