The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine.[1] There are 1.4 L and 1.6 L versions of this engine.

The Gamma II can apparently run in Atkinson cycle (leaving intake open longer for more complete burn but less displacement) under low loads for additional fuel economy with the ability to shift to Otto cycle on demand under high loads or for extra acceleration.

Gamma I

1.4 MPi (G4FA)

The G4FA is a engine. Bore and stroke is . It has MPI and makes at 6,300 rpm and of torque at 4,200 rpm. Power is dropped to at 5,500 rpm and of torque at 4,200 rpm in the Hyundai i20. The engine features double overhead cams with 4 valves per cylinder and a chain driven camshaft with continuously variable valve timing system CVVT on intake camshaft only. It is replaced by the 1.4 L Kappa (G4LC) engine.

Applications

1.6 MPi (G4FC)

The Gamma 1.6 MPI version features the same 77mm bore as the 1.4 (G4FA) but an increased 85.4mm stroke and makes at 6,000 rpm and of torque at 4,200 rpm. In 2010, the G4FC was replaced by the G4FG engine.[2]

Applications

1.6 FLEX (F4FA/F4FC)

Flex fuel version of the Gamma 1.6 MPi. Bore and stroke are 77mmx85.4mm and the engine makes at 6,000 rpm and of torque at 5,000 rpm.

Applications

1.6 LPI (L4FA/L4FC)

It is a hybrid variant with liquefied petroleum gas engine and electric motor.

Applications

Gamma II

1.6 MPi (G4FG)

Released in 2010, the Gamma II MPI version with dual CVVT (continuous variable valve timing) is a 1591cc engine that makes at 6,000–6,300 rpm with of torque at 4,500–4,850 rpm.

Applications

1.6 FLEX (F4FG)

Flex fuel version of the Gamma II 1.6 MPi. Bore and stroke are 77mmx85.4mm for a total displacement of 1591cc. The engine makes at 6,300 rpm and of torque at 5,000 rpm.

Applications

1.6 GDi (G4FD)

The 1.6 Gamma GDi engine is a gasoline direct injection engine, with Dual-Continuous Variable Valve Timing (D-CVVT).[6] Power output to at 6,300 rpm and at 4,850 rpm.[7]

Applications

1.6 T-GDI (G4FJ)

Announced in 2011,[8] it is a version of 1.6 Gamma GDi with twin-scroll turbocharger, air guided intercooler, direct fuel injection system and dual CVVT. It produces 2040NaN0 at 6,000 rpm with of torque at 1,500–4,500 rpm. A detuned version is available with 1770NaN0 at 5,500 rpm.

The engine was unveiled in the 11th Hyundai-Kia International Powertrain Conference.[9]

The engine has been revised in the 2nd Generation Veloster Turbo to include a new pressurized cooling system, higher compression ratio of 10:1, electronically actuated wastegate, and a new ECU (CPEGD2.20.3).

Its improved version equipped with Continuously Variable Valve Duration (CVVD) was released in 2019 as the Smartstream G1.6T (G4FP) engine.
