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.

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.

Earth Dreams Technology. The engine uses a single turbocharger from Wastegate Type & Variable Geometry Turbocharger (VGT). It enables strong power from about 1,500 rpm. With Diesel particulate filter (DPF), IDLE STOP SYSTEM, Exhaust gas recirculation SYSTEM (EGR) & Small Size Intercooler.

Applications

The i-CTDi engine uses a variable-nozzle turbocharger from Honeywell or Garrett. It enables strong power from about 1,500 rpm.^[1] This Honda engine is exclusive to European markets where Honda could operate. It meets Euro 4 emission standards

Applications

Whilst the N22A has the intake ports on the front of the engine, the N22B has the new standard rear intake/front exhaust port configuration. The stroke has been slightly reduced to qualify for sub-2200 cc engine displacement, for tax and registration purposes in some jurisdictions. The N22A has an exhaust on the rear of the engine. It meets Euro 5 emission standards
