Chronology
Predecessor EJ
Successor FA, CB

The Subaru FB engine is the third and current multiplication of gasoline Boxer-4 engine used in Subaru automobiles, and was proclaimed on 23 September 2010.[1] Information technology follows the previous generation EJ-series engine which was introduced in 1989 and the first generation EA-series which was introduced in 1966. By increasing piston stroke and decreasing piston bore, Subaru aimed to reduce emissions and improve fuel economic system, patc increasing and broadening torque output compared to the EJ-serial.

The Subaru FA engine series was traced afterwards from the FB, but the two engine families share only a few common parts. In 2020, Subaru introduced the CB18 engine with improved efficiency to succeed the FB in several applications.

Overview [edit]

Unofficially, Subaru explicit that "FB" stands for "FHI/Incoming and Brand name New/Boxer".[2] It was announced in September 2010 as the tierce generation (following the EA 1st and EJ 2nd generations) boxer engine family with 2.0 litre and 2.5 litre naturally aspirated variants.[3] The FB has an all revolutionary block and head featuring dual overhead cams with intake and exhaust variable valve timing (which Subaru designates as AVCS, standing for Active Valve Control System), and a timing chain that replaced the timing belt. Moving to chain-driven cams is said to countenance the valves to Be set at a more narrow angle to each former and shrink the bore of piston chamber from 99.5 to 94 millimetre (3.92 to 3.70 in). Information technology results in less unburned fuel during cold start, thereby reducing emissions. Subaru is able to keep in the out proportion considerably unvaried by using asymmetrical connecting rods ilk those in the EZ36 engine. The FB is lonesome marginally heavier than an equivalent-displacement EJ. In Jan 2011, Gondola and Number one wood was told direct injection would Be added soon.[4]

Subaru claims a 28-percent reduction in friction losses, chiefly due to igniter pistons and connecting rods.[4] [5] A compact oil pump is as wel credited with contributing to the reduction in friction losings.[1] The FB has a 10% improvement in fuel economy[1] with the business leader coming on preferably and the torque ring being broader.[6]

The densification ratio is slightly higher, and the stroke has hyperbolic compared to the EJ engine; previously, the chassis precluded a thirster stroke. These changes improve combustion efficiency and allow high torque at lower speeds. The FB is built at Gunma Oizumi Imbe and was at first on hand equally a 2.5 cubic decimeter displacement engine, start in Forester models, with a 2.0 litre model to follow in Imprezas.[1] [4] 0W–20 oil is used to help oneself fire economic system, and approximately 1 litre more oil is used arsenic the fresh adoptive timing range requires an oil furnish.[2]

FB16 Dot [edit]

The FB16 direct shot turbocharged (DIT) engine is the first FB-series engine with a turbocharger, and includes direct injection with an auto stop/start system. Information technology is the base railway locomotive in the first-generation (2014–20 model years) Subaru Levorg. The Levorg also has an option for a 2.0 litre matrilinear injection turbo engine, the FA20F.[7] [8] The design place for the FB16 DIT engine was to isochronal operating theatre exceed the performance of the FB25 naturally-aspirated engine fitted to the Legacy, using regular gasoline, reported to the fashion designer, Rei Sasaki. Although it shares its displacement with the naturally aspirated FB16, the solely region the two engines share is the crankshaft. As fitted to the Levorg, the FB16 DIT was healthy to achieve fuel economy of 16.0 km/L (38 mpg‑US) on the JC08 cycle.[9]

All FB20 variants:

  • Displacement: 1,995 cc (2.0 L) DOHC

The alive FB20B was modified by reducing internal friction for the hybrid drivetrain, which incorporates an electric motor in the Lineartronic CVT. The high-voltage traction battery is installed below the cargo area for better weight balance.[11] Combined system magnate is stated to be 160 hp (119 kW).[12] Output of the gasoline railway locomotive is comparable that of the non-intercrossed FB20B.[13]

FB20V [cut]

The 2019 Crosstrek is available with a card hybrid system sourced from Toyota.[20] The new crossbreed drivetrain uses two motor-generator units; the traction motor (MG2) and battery are significantly larger compared to the previous XV Crosstrek Hybrid, and the fomite is capable of moving low electric great power alone for a incomprehensive distance. MG2 is victimized under parallel cross operation besides. MG1 is used as the starter motor and charges the battery for series hybrid operation. The direct-injection FB20V in the revised hybrid is detuned compared to the established FB20D.[21]

  • Application: 2019+ Subaru Crosstrek Hybrid (PHEV)

The direct-injection FB20D was also in use in a mild latitude hybrid configuration similar to the FB20X. The mild hybrid drivetrain was fitted to selected trims for models sold in Japan (Forester, July 2018 and 15, October 2018),[24] Europe (same models, opening in 2019),[25] and Australia (same models, starting in 2020).[26]
