Honda N22A N22B engine

The Honda N-type engine (Honda Ngata engine) is an in-line 4-cylinder Water-cooled diesel engine with Common rail Direct injection for medium-sized vehicles manufactured by Honda Motor Co Ltd.

History

The N series is Honda's first automotive diesel engine, for medium-sized vehicles developed in-house as a successor to the diesel engine that had been supplied by Isuzu Motors. 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 2,200cc N22A i-CTDi (Intelligent Common rail Turbocharged Direct Injection) was introduced for the first time in the European specifications of the 7th generation Accord and 4th generation Accord Tourer (Accord Wagon in Japan) announced at the Frankfurt Motor Show on September 1, 2003. The third-generation CR-V European specification N22A-equipped vehicle announced on September 4, 2006 was equipped with a DPF.

On September 25, 2006, it was announced that the improved N22A engine had met the US emissions regulations "Tier II Bin 5." In 2007, the name I-DTEC was announced. The 2,200cc N22B i-DTEC was adopted for the first time in the European specifications of the 8th generation Accord and the 5th generation Accord Tourer released in 2008.

Later variants 1.6L i-DTEC was adopted for the first time in the Civic European specification released in 2013. N15A 1.5L i-DTEC was adopted in Amaze released in India in 2013. 160ps 1.6L i-DTEC was adopted for CR-V in 2015.

N22A i-CTDi 

The biggest feature is that the cylinder block adopts an aluminium block manufactured with a technology called "semi-solid (semi-molten) casting”, which has succeeded in achieving both high rigidity and weight reduction. There are two intake and two exhaust valves, and the camshaft is driven by a timing chain. The fuel injection system is a high-pressure common rail type direct injection, and a variable nozzle turbocharger from Honeywell. with an intercooler installed. Some models are equipped with a DPF (Diesel Particulate Filter) in the exhaust system.

N22B i-DTEC 

It was developed with the goal of meeting the US exhaust gas regulations "Tier II Bin 5," which requires NOx emission levels equivalent to those of gasoline vehicles with new type front intake/rear exhaust port configuration, and also conforms to Europe's "Euro 5." The exhaust port of the cylinder head has been changed to the front, the compression ratio and injection nozzle have been renewed, and the displacement has been reduced to 2.2 L or less by reducing the stroke. This is available with the five-speed automatic transmission only.
