Honda J engine

Article Discussion

Template:More citations needed Template:Infobox automobile engine The J-series is Honda's fourth production V6 engine family introduced in 1996, after the C-series, which consisted of three dissimilar versions. The J-series engine was designed in the United States by Honda engineers. It is built at Honda's Anna, Ohio, and Lincoln, Alabama, engine plants.

The J-series is a 60° V6 unlike Honda's existing 90° C-series engines. Also unlike the C series, the J-series was specifically and only designed for transverse mounting. It has a shorter bore spacing (Template:Convert), shorter connecting rods and a special smaller crankshaft than the C-series to reduce its size. All J-series engines are gasoline-powered, use four valves per cylinder, and have a single timing belt that drives the overhead camshafts. VTEC variable valve timing is used on almost all applications, with exceptions being the J30AC and J35Y8 (which use Variable Timing Control [VTC] instead).

One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. Initially, the system turns off one bank of cylinders under light loads, turning the V6 into a straight-3. Some versions were able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads and four-cylinder use under medium loads.

J25Edit

The J25A was used only in the Japanese domestic Inspire/Saber models. The J25A displaced Template:Convert. Its bore and stroke was Template:Convert. The J25A used a 10.5:1 compression ratio and was a SOHC VTEC design. Output was Template:Convert at 6200 rpm and Template:Convert of torque at 4600 rpm. It had a variable intake manifold to optimize torque output across varying engine speeds and engine response.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

J25AEdit

J30Edit

The J30A displaces Template:Convert and is a SOHC VTEC design. Its bore and stroke is Template:Convert. Output for the J30A1 was Template:Convert at 5500 rpm and Template:Convert of torque at 4800 rpm. The J30A4 pushed output to Template:Convert and Template:Convert using a three-way VTEC system, a higher (10.0:1) compression ratio and a novel exhaust manifold cast as one piece with the cylinder head. It weighs nearly Template:Convert less and is an inch shorter than J30A1. This version was on the Ward's 10 Best Engines list for 2003 and 2004. The IMA hybrid version was on the list for 2005. In 2006 Honda created the J30A5 to mark the 30th anniversary of the Accord. It boosted output to Template:Convert (SAE Net 08/04) and Template:Convert (SAE Net 08/04) of torque. According to Honda, horsepower gains were achieved with improvements to the airflow of the intake and exhaust system.

J32Edit

The J32A displaces Template:Convert and is a SOHC VTEC design. Its bore and stroke is Template:Convert. Output was Template:Convert at 5600 rpm and Template:Convert at 4700 rpm for the J32A1, with the J32A2 raising output to Template:Convert at 6200 rpm and Template:Convert at 3500–5500 rpm. A more aggressive camshaft, more free flowing intake/exhaust, and a 2-stage intake manifold produced a Template:Convert increase over the J32A1. The J32A3's output in the 2004/2005 TL is Template:Convert. Due to changes in SAE testing methods, 2006–2008 model years have a reduced output rating of Template:Convert, despite being mechanically identical. The J32A3 includes a one-piece exhaust manifold cast with the cylinder head, first introduced on the J30A4.

J37Edit

The J37 uses a die-cast aluminum block with aluminum cylinder liners. Primarily due to the cylinder liners being made from aluminum instead of cast-iron the engine weighs less than the J35Z engines. The intake manifold is made from a cast magnesium alloy.
