Suzuki M13A 1.3L engine Specs, Problems, Reliability. The M13A is a 1.3-liter inline four-cylinder gasoline engine, the tiniest one from the Suzuki M engine household. The Suzuki M13A was used in popular little SUV Suzuki Jimny (M13AA) and compact automobiles such as Suzuki Ignis, Suzuki Swift, and Suzuki Liana. When the fourth-generation Suzuki Jimny was launched, the engine production began in 2000 and was stopped in 2018. The 1.3 L M13A was changed with a more powerful 1.5-liter K15B engine out of the Suzuki K engine family.
The engine has an aluminum cylinder block with cast-iron damp liners. On top, there is an aluminum 16-valve cylinder head with double overhead camshafts. The M13A engine uses a timing chain. The valvetrain features solid containers with shims over pails utilized for valve clearance change (no hydraulic lifters). The valve clearance inspection is needed every 20,000 miles (30,000 km).
There two consumption valves and 2 exhaust valves per each cylinder. The diameter of consumption valves is 37.0 mm (1.457 in), and the exhaust valves are 25.0 mm (0.984 in). The engine is geared up with VVT (Variable Valve Timing) system on the intake camshaft, but the version without VVT was available for some markets. The headcover and intake manifold are made of aluminum.
The M13A features a standard Multi-point fuel injection (MPFI) that interacts with the electronically-controlled throttle – ETCS (Electronic Throttle Control System).
