Chronology
Predecessor Alpha
Successor Smartstream 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.

Contents

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

1.4 MPi (G4FA)

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)

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)

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)

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]

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)

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)

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

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.
