# Honda N engine

The N series is Honda's first automotive diesel engine, an inline-four for medium-sized vehicles. It uses common rail direct injection, which Honda brands as i-CTDi (Intelligent Common-rail Turbocharged Direct injection). The most notable feature is the aluminium block, which uses proprietary technology in the manufacturing process to provide light weight and high rigidity. Roller chains drive two overhead camshafts. A variable-geometry turbocharger and intercooler are used.

## N15A1 (Earth Dreams i-DTEC)

The i-DTEC engine uses a 2-Stage turbocharger from Wastegate Type & Variable Geometry Turbocharger (VGT) left/right. It enables strong power from about 1,500 rpm. With Diesel particulate filter (DPF), Start-stop system, Exhaust gas recirculation system (EGR) & Small Size Intercooler.
