Suzuki K15B 1.5L Engine
Here in this post, I have gathered information about the Suzuki K15B 1.5L Engine from its official website, including its specifications, Problems, and Reliability.
We believe in providing reliable information to our readers, therefore we prefer to obtain information on the Suzuki K15B 1.5L Engine from authentic sources.
This article, which has been updated, has all the information you require about the Suzuki K15B 1.5L Engine.
The K15B debuted in 2018, and it is a 1.5-litre inline 4-cylinder gasoline engine with natural aspiration.
The K15B is the largest of Suzuki’s inline-four engines. Popular Suzuki vehicles, including the fourth-generation Suzuki Jimny (Sierra/Global), the Suzuki Ciaz, and the Suzuki Ertiga, a compact MPV with room for seven people, all include the 1.5L engine as standard equipment.
The previous small-displacement engine series, which included the M13A and M15A, was discontinued in favour of the new engine.
All of the moving parts in the K15B are made of aluminium. The cylinder block is made of aluminium and features cast-in cylinder liners.
Within the block, the crankshaft is installed at an angle relative to the cylinders. Lightweight pistons with low-tension rings and split-type connecting rods are used in the motor.
Cylinder heads made of aluminium alloy with four valves per cylinder and twin overhead camshafts sit above the engine block.
The timing chain used in the engine is both sturdy and durable; it is also silent, which helps reduce the engine’s overall level of noise, vibration, and harshness.
The camshafts for both the intake and the exhaust are equipped with variable valve timing (VVT).
Camshafts drive bucket hydraulic lifters to open and close the valves. There’s a plastic valve cover on there.

Suzuki K15B 1.5L Engine Problems
It is too soon to speak about frequent issues with the new 1.5L K-series engine, as it has only recently entered the market.
New owners have noted greater oil consumption from the get-go, which is likely par for the course with this particular motor.
Not only that, but the modern injectors used to improve atomization are sensitive to the quality of the fuel, even though conventional fuel injection is still used.
