Honda N-Series diesel engines

The N series is Honda's first diesel engine. It is a four-cylinder common-rail diesel engine for medium sized Honda vehicles. It features the ubiquitous Common Rail Direct Injection configuration which Honda brands as their i-CTDi (Intelligent Commonrail Turbocharged Direct injection). The most notable feature is the aluminum block, which uses proprietary technology to the manufacturing process of the cylinder block, and provides both light weight and high rigidity. The valvetrain is a DOHC style with chain driven camshafts. The Fuel System is a high-pressure (1600bar) Common rail direct injection type with a variable geometry turbocharger with intercooler.
