[edit] G10

The G10 is an inline 3 cylinder engine utilizing aluminum alloy for the block, cylinder head and pistons. The G10 has 1.0 liter of displacement and is equipped with either a carburetor or electronic fuel injection and has an optional turbocharger. It has a single overhead camshaft driving six valves.

A 2.91 in (73.9 mm) bore and 3.03 in (77 mm) stroke give the engine a total of 1.0 L (993 cc/60 in³) of displacement. It produces 48 hp (36 kW) at 5100 rpm and 57 ft·lbf (77 N·m) at 3200 rpm with 9.5:1 compression in the carburated model, 55 hp (41 kW) at 5700 rpm and 58 ft·lbf at 3300 rpm in the fuel injected model.

From 1985 to 1986 the engine used a hemispherical head carbureted design. Later, as fuel injection was mandated, the cylinder head was redesigned to add the additional cooling required. This caused the fuel economy of the engine to suffer. A detuned 49 hp unit was used in the ultra-fuel-efficient Geo Metro XFi model, which delivered as much as 58 miles per gallon.

As the 3-cylinder engines aged however, they began to become less stable and subject to vibration as well as minor deficiencies in the fuel injection system that led to decreased fuel economy. A flaw exists in 3-cylinder engines equipped with an EGR valve - if the valve fails or the EGR passages become blocked, the center combustion chamber can get too hot, and over time, lose compression due to exhaust valve failure.

[edit] G13

The G13 is an in line 4 cylinder engine utilizing aluminum alloy for the block, cylinder head and pistons. Displacing 1.3 L (1298 cc/79 in³), fuel delivery is either through a carburetor, a single point fuel injection or a multi-point fuel injection.

The engine was produced as either an 8 valve with a single overhead camshaft (G13A) or as a 16 valve with double overhead camshafts (G13B).

[edit] G13A

The SOHC G13A was used in the following vehicles:

[edit] G13B

The DOHC G13B was used in the following vehicles:

[edit] G13BA

The SOHC 8-valve G13BA was used in the following vehicles:

[edit] G13BB

The SOHC G13BB has electronic MPFI fuel injection, generating 56–59 kW (75–79 hp) at 6,000 rpm and 104–115 N·m (77–85 ft·lbf) at 4,500 rpm, and was used in Suzuki Baleno / Esteem from 1995 to 2000 and Suzuki Jimny from 1999 to 2004.

The Swift GTI twin cam is well known. Older Swift GS types (before '89) used a special camshaft and carburetor, which are now sought after items. There is a smaller 993 c.c. Variant (G10B) that was used in the 1993 Suzuki Alto.
