In 1989, Honda released the VTEC system. [13] While the earlier Nissan NVCS alters the phasing of the camshaft, VTEC switches to a separate cam profile at high engine speeds to improve peak power. The first VTEC engine Honda produced was the B16A which was installed in the Integra, CRX, and Civic hatchback available in Japan and Europe ...
A Honda K24A Engine with i-VTEC. VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
The Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters.
Variable Cylinder Management (VCM) is Honda's term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving. The second version of VCM (VCM-2) took this a step further, allowing the engine to go from 6 cylinders, down ...
The J30A4 pushed output to 242 hp (180 kW) and 212 lb⋅ft (287 N⋅m) 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 20 lb (9.1 kg) less and is an inch shorter than J30A1.
This can cause fuel leaks and lead to an increased risk of injury, warned NHTSA. This recall comes after another one issued by Honda for 1.7 million cars in early October due to steering wheel issues.
Honda K24A4 2.4L DOHC i-VTEC Engine installed in 2003 Honda Accord. The Honda K-series engine is a line of four-cylinder four-stroke car engines introduced in 2001. The K-series engines are equipped with DOHC valvetrains and use roller rockers on the cylinder head to reduce friction.
They are one of the few Honda 4-cylinder automobile engines that are designed to sit longitudinally for rear wheel drive. These engines are a distant relative to the F-series engines found in the mid-1990s Honda Accord and Prelude. [1] To get most out of the compact-sized engine, Honda engineers utilized technology derived from Honda's racing ...
