Draft:Suzuki J engine


The Suzuki J engine family is a series of all aluminium inline-four cylinder engine from Suzuki, first introduced in February 1996. The displacement ranges from 1.8 to 2.4 litres. It features dual overhead cams, 16 valves in total, multi-port fuel injection, and variable valve timing in later models. The J engine was Suzuki's 'big block' series engine. To keep development costs down, it had a significant parts and design commonality with the H family of V6 engines: aluminum block and cast iron sleeve structure, and valve train chain drive.[1]
