Chronology

SuccessorSmartstream G1.6/G1.6T

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.

Being a development from the Alpha II engine, significant changes include the aluminum construction of the block and cylinder head, resulting in a 15 kg weight reduction to just under 100 kg, and the use of a timing chain instead of belt. It is also the first offset crankshaft engine developed by Hyundai.[2]

Production takes place in Shandong, (China, by Hyundai WIA), Žilina (Slovakia), Hwaseong (South Korea) and Irungattukottai (India).[2]

Gamma I

[edit]

1.4 MPi (G4FA)

[edit]

The G4FA is a 1.4 L (1,396 cc) engine. Bore and stroke is 77 mm × 75 mm (3.03 in × 2.95 in). It has MPI and makes 111 PS (82 kW; 109 hp) at 6,300 rpm and 14 kg⋅m (137 N⋅m; 101 lbf⋅ft) of torque at 4,200 rpm. Power is dropped to 100 PS (74 kW; 99 hp) at 5,500 rpm and 13.9 kg⋅m (136 N⋅m; 101 lbf⋅ft) 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)

[edit]

The Gamma 1.6 MPI version features the same 77mm bore as the 1.4 (G4FA) but an increased 85.4mm stroke and makes 124 PS (91 kW; 122 hp) at 6,000 rpm and 15.9 kg⋅m (156 N⋅m; 115 lbf⋅ft) of torque at 4,200 rpm. In 2010, the G4FC was replaced by the G4FG engine.[3]

Applications

1.6 FLEX (F4FA/F4FC)

[edit]

Flex fuel version of the Gamma 1.6 MPi. Bore and stroke are 77mmx85.4mm and the engine makes 130 PS (96 kW; 130 hp) at 6,000 rpm and 16.5 kg⋅m (162 N⋅m; 119 lbf⋅ft) of torque at 5,000 rpm.

Applications

1.6 LPI (L4FA/L4FC)

[edit]

It is a hybrid variant with liquefied petroleum gas engine and electric motor. To prevent knocking it has a higher compression ration of 12. instead of 10.5.

In this configuration the engine runs in Atkinson cycle (leaving intake open longer for more complete burn but less displacement).[2]

1.6 MPi (G4FG)

[edit]

Released in 2010, the Gamma II MPI version with dual CVVT (continuous variable valve timing) is a 1,591 cc (97.1 cu in) engine that makes 123–134 PS (90–99 kW; 121–132 hp) at 6,000–6,300 rpm with 15.4–16 kg⋅m (151–157 N⋅m; 111–116 lbf⋅ft) of torque at 4,500–4,850 rpm.[3]

Applications

1.6 FLEX (F4FG)

[edit]

Flex fuel version of the Gamma II 1.6 MPi. Bore and stroke are 77mmx85.4mm for a total displacement of 1,591 cc (97.1 cu in). The engine makes 130 PS (96 kW; 128 hp) at 6,300 rpm and 16.5 kg⋅m (162 N⋅m; 119 lbf⋅ft) of torque at 5,000 rpm.

Applications

1.6 GDi (G4FD)

[edit]

The 1.6 Gamma GDi engine is a gasoline direct injection engine, with Dual-Continuous Variable Valve Timing (D-CVVT).[7] Power output to 140 PS (103 kW; 138 hp) at 6,300 rpm and 17 kg⋅m (167 N⋅m; 123 lbf⋅ft) at 4,850 rpm.[8] It was introduced in 2010 in the Hyundai ix35 and Kia Sportage.[2]

Applications

1.6 T-GDI (G4FJ)

Exhaust and twin-scroll turbocharger of the T-GDI version

Announced in 2011,[9] 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 204 PS (150 kW; 201 hp) at 6,000 rpm with 27 kg⋅m (265 N⋅m; 195 lbf⋅ft) of torque at 1,500–4,500 rpm. A detuned version is available with 177 PS (130 kW; 175 hp) at 5,500 rpm.

The engine was unveiled in the 11th Hyundai-Kia International Powertrain Conference.[10]

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.
