A V4 cylinder has 4 ignition coils. In some cases, a compactor multi-outlet ignition coil provides cylinders to deliver the highest efficiency level, for example, 2 coils for 4 cylinder engines.
Some of the Most Popular V4 Engines
The particular model range starts with a 192 HP turbocharged 1.5-liter four-cylinder. They also have 252 turbocharged 2.0L 4 cylinders with 4 ignition coils.
Subaru Impreza has a 2.0 liter turbocharged and intercooled motor, with significant variations in the engines with 4 coils.
Hyundai Elantra Has 3 Engine Options With 4 Coils They Are
- 2.0-liter four-cylinder with 147 horsepower and 132 pound-feet of torque (SE, SEL, Limited)
- 1.6-liter turbocharged four-cylinder with 201 horsepower and 195 pound-feet of torque (N Line)
- 2.0-liter turbocharged four-cylinder with 276 horsepower and 289 pound-feet of torque (N)
TOYOTA 3RZ-FE – 2693 CC
This is a 4 cylinder engine that was specifically developed in the 80s for the HiAce van, Prado SUVs and Hilux pickups. This was known as one of he most modern engines which has a cast block head covered with 16 valve head with a timing chain and no hydraulic lifters. The engine can also produce a torque of 240 Nm at 4000 RPM from 152 horsepower.
Toyota 3RZ-FE 2.7L
Toyota developed the 3RZ-FE, a 2.7-liter inline 4 cylinder gasoline engine, in 1994 to 2004. Each cylinder has two intake sprinters that are uniquely engineered to maximize horsepower. The engine received an electrically operated fuel ignition system as well as Toyota’s Electronic Spark Advance (ESA) ignition, which allowed the ECM to adjust engine performance based on sensor signals. Instead of a coil pack, early engines used a single ignition coil and a basic distributor.
Alfa Romeo Twin Spark 16V
This was a 4 cylinder engine with 2 spark plugs per cylinder. Individual ‘coil over spark’ ignition is used on the 16-valve engine, with the timing of the ignition regulated directly by the Bosch engine control unit, and each coil fires two spark plugs at the same time.
On the earlier 16 valve engines, one coil would fire a spark plug in the cylinder nearing the top of the compression stroke and also a spark plug in the cylinder rapidly approaching the top of the exhaust. As a result, each coil serves two spark plugs, and each cylinder is served by two coils in this layout. In the event of a coil failure, one of the two plugs will still function, in this case.
Do V4 Engines Use Distributorless Ignition Systems?
Yes, V4 engines use distributorless ignition systems in which the distributor of the electronic ignition system is restored with the number of induction coils. The system provides direct voltage to the spark plugs.
How many ignition coils does the distributorless system use?
The system uses one coil per cylinder or pair of cylinders. Furthermore, the timing is controlled by an Ignition Coil Unit and the engine Control Unit. Altogether this makes the system work more efficiently and proficiently.
Are Compact coils used in V4 ignition systems?
Yes, compact coils are used in V type engines. 1 ignition coil per 2 pairs of cylinders is provided by a compact (or multi-outlet) ignition coil. For example, two coils for a V4 engine, 3 coils for a V6 engine, and 4 coils for an V8 engine. When equating to the first series of ignition coils, its design provides high heat capacity, empowering for a mass depletion of up to 40%.
