Honda J 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 Japan, with engineering taking place in the United States. 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 (), 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.

J25

The J25A was used only in the Japanese domestic Inspire/Saber models. The J25A displaced . Its bore and stroke was . The J25A used a 10.5:1 compression ratio and was a SOHC VTEC design. Output was at 6200 rpm and of torque at 4600 rpm. It had a variable intake manifold to optimize torque output across varying engine speeds and engine response.

J25A

J30

The J30A displaces and is a SOHC VTEC design. Its bore and stroke is . Output for the J30A1 was initially and of torque, later increased to and of torque. The J30A4 pushed output to and 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 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 (SAE Net 08/04) and (SAE Net 08/04) of torque. According to Honda, horsepower gains were achieved with improvements to the airflow of the intake and exhaust system.
